Chapter # 01 INTRODUCTION 1.1 Introduction: Financial crisis occurred in recent years (2007) has come up with a need for policymakers and economists to identify those firms which are financially distressed. The most versatile instrument for the purpose of identification is stock price because of availability and frequency of information. Typically, financially troubled firms should have high returns on stocks to be expected and higher risk indicators based on market, such as earnings to price ratio and ratio of book- to- market; because wisdom based on conventional advocate that those firms which have higher risk will have definitely lower values of market as compared to other firms. Consequently, financial distress can also be the link to account for the value premium, i.e., the significant positive relationship between returns on stocks and indicators of risk based on market as frequently argued in literature. The most confusing anomaly of asset pricing is the terrible performance of stocks of firms approaching towards financial distress. The result contrasting to it, although yet comprise an incongruity, but understanding of this incongruity will be simple. Distress aspect is explained by Fama and French (1992), in their opinion it is inadequately measured by past betas would settle the elevated returns for those firms who have high book to market, however Capital Asset Pricing Model (1964) may be considered insufficient for the estimation of distress risk. The literature on asset pricing evoked the financial distress concept to explain abnormal patterns in the range of stock returns (Chan and Chen, 1991) and Fama and French (1996). According to this phenomena certain companies have set 1 elevated probability that show their failure to meet financial obligations these firms are financially distressed and stocks of these companies move align, hence risk associated with such stocks is not diversifiable so, investor demand premium with respect to bearing risk on such type of stocks. Standard model of asset pricing i.e CAPM is not able to capture the premium that is demand by investor for bearing risk on distress stocks. Theoretical underpricing of CAPM build by Sharpe (1964) and Lintner (1965) never led to a pragmatic success. In early empirical work, the Black (1972), extended the model, which can hold a compliment exchange of standard return for market beta, got some success. But in the era of late 1970’s many variables uncover by research like size, P/E ratio and thrust that insert into the justification of average returns grant by beta. These problems are severe enough to nullify most functions of the CAPM. Researchers show that average return of stocks related to various variables. Such as its size, book-to-market equity (BE/ME), “the ratio of the book value of common equity to its market value)”, earning/price (E/P'), cash flow/price (C/P'), and growth of historical sales. (Banz, 198l), Basu (1983), Rosenberg, Reid, and Lanstein (1985), and Lakonishok, Shleifer andn Vishny (1994).) These are patterns regarding to which average returns of stocks vary. CAPM doesn’t explain these patterns (Sharpe (1964) and Lintner (1965)), these are normally called as anomalies of CAPM. Most of the anomalies of CAPM are related to average-returns of stocks and model presented by Fama and French (FF 1993) three factor model captured these anomalies and tested pricing of these anomalies in equity market. The model state that three factors are sensitive to expected return on a portfolio in surplus of risk-free rate: (i) surplus return on portfolio of extensive market (ii) in a given portfolio difference between return on stocks of small size and large stocks 2 (SMB, Small minus Big); (iii) the discrepancy between return on those portfolios having stocks of high-book-to-market and those portfolios having stocks of low-book-to-market. (HML, High minus Low). Fama and French (1995) illustrate that book-to-market equity and incline on HML substitute for relative distress. Weak firms with steadily low earnings lean to have high BE/ME and affirmative slopes on HML; financially sound firms with steadily high income have low BE/ME and downbeat slopes on HML. Using HML to make clear returns is therefore in line with the support of Chan and Chen (1991) that there is co variation in proceeds associated to relative distress that is not detained by the market return and is compensated in average returns. Similarly, using SMB to explain returns is in line with the evidence of Huberman and Kandel (l987) that there is co variation in the returns on small stocks that is not captured by the market return and is compensated in average returns. Financial distress is major risk factor that affects the stocks. Firms which are financially distress represent unhealthy firms and healthy firms are those who meet their financial standards. In addition to HML and SMB we can also incorporate HMU healthy minus unhealthy. Hence the purpose of this study is to explore the relation of financial distress and stocks returns by adding variable of HMU in typical Fama and French three factor model and to find out does financial distress exist as a risk factor. 1.2 Rationale of the Study and Research Gap: There is need to look at financial distress as a risk factor which can affect the expected return on stocks in a given portfolio because when we include small and big firms, high and low firms, there must be some firms which are meeting their financial obligations and some which are below the standard they are facing the financial distress risk factor and 3 investor demand risk premium for holding such stocks. The need of hour is to mention such firms separately by finding the difference of their stocks returns can be known as healthy and unhealthy firms, HMU. The relation of financial risk and returns on stocks has been studied by many researchers in different aspects in developed countries. Models of bankruptcy have been used by many researchers for division of firms by possibility of failure to pay, so it is found by them again and again that the higher the failure likelihood, the poorer the return (Dichev (1998). Regular amendment for risk makes this relation stronger. Moreover the effect is more dominant in those companies with low ratio of B/M, where threat of failure is implausible to play a significant role (Griffin and Lemmon (2002). They study the distress risk with book to market equity and stocks returns. One well known explanation for demanding high premium for high book to market equity is that those firms are allocate a privileged risk premium because of the larger risk of distress. Consistent with this analysis, Fama and French (1995) and Chen and Zahng (1998) show that firms with high book to market equity (BE/ME) have determinedly low income, higher fiscal leverage, more earnings ambiguity and are more likely to slash dividends contrast to their low BE/ME corresponding item. In distinction, Dichev (1998) uses procedures of bankruptcy risk projected by Ohlson (1980) and Altman (1968) to discover firms with high possibility of financial distress and get that these firms have a tendency to have low standard stock returns. Dichev’s consequences appear to be conflicting with the analysis that firms with elevated BE/ME make high profits as a premium for distress risk. Researchers tried to predict financial distress by analyzing the performance of distress stocks (Campbell, et al, 2010). Some researcher incorporate the financial distress risk factor with equity returns by using the variable difference between 4 winning and losing stocks, UMD Gao et al (2013). Although financial distress has been reported in many studies in foreign countries but those studies done with several limitations. Financial distress is never studied in the context of healthy and unhealthy stocks. And there is no evidence of such type of study in Pakistan as previously no one has theoretically and empirically examined the full interaction among portfolio stock returns and the difference between financially distress stocks returns and healthy stocks returns. Hence there is need to conduct research on this topic. The proposed study tries to discover the pricing of distress risk on stocks returns. 1.3 Theoretical Foundation: Asset pricing theory (CAPM): This theory plays a vital role in proposed study. The birth of theory regarding asset pricing comes from model of (CAPM) given by John Lintner (1965) and William Sharpe (1964). The appeal of CAPM is that it intuitively and powerfully predicts about measurement of risk and captures the relation between risk and return to be expected. It is stated by theory of CAPM that return to be expected on a stock endures a relationship which is linear in nature with covariance of stock with return on portfolio of market. However, the basis of typical CAPM base on some key traditions, which are listed below: • The securities returns presumed to be distributing generally. • The investor functions of utility are either normal or quadratic. • All non-market risk, that is unsystematic, assumed to be eliminated. • The opportunity for risky assets is determined by the existence of assets that are risk free and market portfolio. 5 • Costs and taxes on standard transactions are excluded. Whenever the above listed assumptions are fulfilled the standard model of CAPM is applicable, hence the main concern of investor is linked with the mean-variance of the returns on their stocks. This typical model of single factor is also identified as standard model of two-moment. This model lies on such tradition that is normal distribution of returns and investor function of utility is quadratic. Basically, the fact on which the typical model base is that if the risk is high the return will be definitely high. However, empirically this relation has failed to persist because alone market beta is not able to explain the variations that comes in returns of stocks and the unrealistic assumptions of the model. The empirical evidence on asset pricing show the theme of FINANCIAL DISTRESS to explain otherwise anomalous patterns in the cross-section of stock returns (Chan and Chen (1991) and Fama and French (1996)). The idea is that certain companies have an elevated probability that they will fail to meet their financial obligations; the stocks of these financially distressed companies tend to move together, so their risk cannot be diversified away; and investors charge a premium for bearing such risk.' The premium for distress risk may not be captured by the standard Capital Asset Pricing Model (CAPM) if corporation failures are correlated with deteriorating investment opportunities (Merton (1973)) or declines in unmeasured components of wealth such as human capital (Fama and French (1996)) or debt securities (Ferguson and Shockley (2003)). In this case distress risk may help to explain patterns such as the size and value effects that are anomalies in the standard CAPM. Fama and French (1992) Model: Joint roles of Size, market beta, Earnings/price, book to market and leverage ratios studied by Fama and French on average returns of 6 cross-section stocks for Amex, NYSE and NASDAQ for the period of 1963 to 1990. Results suggest that market beta has no descriptive power while E/P, Size, B/M and leverage have noteworthy descriptive power for the explanation of returns on average. However book to market ratio and size become significant when beta is incorporated, and in explaining the average returns on stocks they appear to absorb the effect of E/P and leverage. FF (1992) thus, argues that risk associated with stock should be multidimensional if pricing of stocks is rational. Fama and French (1993) used technique of time series regression to extend the scope of their study on both bonds and stocks. Returns on monthly basis for bonds and stocks are regressed upon five characteristics: portfolio of market, portfolio of size factor, portfolio of BM, a premium of default and premium of term. Results for bonds and stocks are slightly different. For stocks, three factors come up significant these are returns on portfolio of market, portfolio of size and a book to market portfolio and for bonds two factors are significant and these are default and term. As an outcome, model of three factor constructed by Fama and French (1993) also known as model of asset pricing which incorporates three factor namely factor of market, size and value factor. Study reports that this extension of model is useful for capturing the returns on average for the cross section of stocks. According to this model the return to be expected on portfolio in surplus of rate which is risk free is described in such sense that how returns of portfolio are sensitive to three factors: (i) the surplus return on portfolio of broad market (ii) the difference between portfolio’s returns of small size stocks and portfolio of large size stocks. (SMB) and (iii) the difference between portfolio return having stocks of high B/M ratio and portfolio return having stocks with low B/M (HML). 7 1.4 Problem Statement: Curiosity in the pricing of financially troubled firms is extensive. Chan and Chen (1991) depict insignificant and distressed firms as follow: Their market value is lost, their producers are inefficient and their chances of taking financially leverage is high and they are suffering from problems of cash flows. They are minor in the logic their prices likely to be more responsive to changes in the market, and the chances of their survival are less under unfavorable economic conditions. Theory of asset pricing advocate that for holding stocks of such marginal firms investors will claim. However for bearing such risk whether investors are in reality rewarded or not that is an empirical question. Researchers tried to use different models to classify firms by the possibility of failure. Consistently they reported that firms whose chances of failure are more their returns are respectively low, ( Dichev, 1998). The puzzle of distress risk has got most considerable attraction, both in theoretical and empirical studies. The basic theme regarding distressed stocks is that their returns are low, but on theoretical basis researchers argues, against it being inferred as an abnormality. Campbell, Hilscher,and Szilagyi (2008), advocated that stocks related to those firms which are distressed, in reality, too stumpy to arranged in single framework. It is showed that market betas of financially distressed stocks are higher, their standard deviations are also high and other procedures for measuring risk yet, returns generated by them are low. Thus it becomes important to check that “How financially distress stocks affect the expected stock return of portfolio?” 8 1.5 Research Questions: This study addresses following research questions: ‘’Does financial distress priced as a risk factor in equity market of Pakistan’’? “Does the excess returns on portfolio stocks are sensitive to distress risk or not”? 1.6 Research Objectives: To check the impact of financial distress on stocks returns. To check whether financial distress exists as a risk factor for affecting the expected return on portfolio in the context of listed firms of Karachi stock exchange. To assess the distress risk premium. 1.7 Significance of the study: This paper illustrates a lot of research work done on the topic under discussion and the difference of opinions in the results of authors and it adds significantly to the growing body of literature considering the interaction among financial distress and stocks returns. This study was stimulated by pragmatic phenomena of typical concept of financial distress and underwrites new intuitions to this complex and exciting pitch of research about financial risk. This study tries to overcome the previous limitations (taking HML as proxy for distress) and deliver such a comprehensive form of theoretical framework which is in the form of dynamic process of corporate failure and supported empirically. Hence this study contributes a proper mechanism for the better understanding of procedures for financial distress in the context of practical and theoretical domain. 9 1.7.1Theoritical Contribution: This study make addition of new asset pricing anomaly in the typical Fama and French 3 Factor Model by adding a new variable, HMU. This addition is significant in the sense because in previous studies financial distress is measured by bankruptcies, so for the first time financial distress is quantified in the context of stocks returns. The present developed model about financial distress can be useful for both academic purposes to have the logical understanding of financial distress in corporate sector of Pakistan and also can become as a base for the further development of models regarding financial risk which are still absent theoretically. 1.7.2 Practical Contribution: The complete theoretical debate of proposed study was initiated by practitioners and their interpretations concerning the discrepancy occurring between theory and practice. Theory only nominate market risk this is only risk which is priced in returns of equity and practiced. But financial risk incorporating continuously for last several years. The requirement for theoretical explanation that why some investors, like private houses of equity, institutional investors and hedge funds become able to outperform the market by overlooking risk of market inspired this study to go in this direction. The results of this empirical study can be used by practitioners to improve their level of understanding and knowledge about distress risk and financial distress. The world of finance can take the advantage of this study in following listed ways. 10 Study how value of company suffers in the state of financial distress and how distress risk affects the weakening performance of bankrupt candidate. Enhance knowledge about how to price distress stocks and become able to progress strategy about making investment in those securities which are financially distressed. This study brings the community of science a bit advance in understanding what actually happens when a company suffers from financial distress and why those stocks which are financially distressed become attractive for an investor with comprehensive risk appetite. This research contribute to theory of asset pricing by categorizing the distress risk nature, and answer positively the research question about pricing this type of risk in equity market of Pakistan. It can also provide useful information that helps regulators to revisit their policies and design a realistic structure in which no firm face financial distress risk factor. 1.8 Organization of the Study: The proposed study combined in five chapters. Chapter 1 presents introduction, which includes background, research gap, problem statement, research questions, research objectives, and significance of study. In chapter 2 literature of (1) Capital Asset Pricing Model; (2) Fama and French three factor Model (3) (SMB, small minus big); (4) (HML, high minus low), (5) Financial distress and stocks returns (HMU, healthy minus unhealthy) explained and hypothesis are developed, chapter 3 described data and methodology and chapter 4 presents results and discussion. Finally in chapter 5 conclusion, policy implications, limitations and future directions are given. 11 Chapter # 2 LITERATURE REVEW The present study is aimed to analyze the impact of Financial Distress on stocks returns in non-financial listed firms of Pakistan. In doing so, it is essential to delve into the literature and historical perspectives of these variables to analyze the nature of relationships that have been explored and supported by different studies. Major findings of these studies are reviewed below. 2.1 Capital Asset Pricing Model Pioneers of CAPM are Sharpe (1964) and Lintner (1965), CAPM states that rate which is risk free and premium on expected risk both combines and become equal to expected return. It points out that variation in cross-sectional expected returns is only explained by market beta. In essence, according to CAPM a stock is expected to earn the rate which is free of risk together with a compensation for tolerating extra risk as précised by the beta of that stock. Data of private sector in UK scrutinized, Greene (1990) initiate that CAPM is not fit for data of UK, though Sauer and Murphy (1992) have assured that for explaining the data of German stock market CAPM is best model. However, Hawawini (1993), have study more thoroughly, the healthiness of CAPM in stock markets of France, Canada, Japan, UK, Spain and the US cannot be validated. Non-normality in returns have shown in various studies, thereby restrict the use of model of mean-variance to only pricing on theoretical basis (Galagedera, 2004). 12 Unconditional distribution of security returns is not normal stated by Chung et al. (2001) .The extensions of standard CAPM to high co-moments models are led by ambiguous results of it. Investors were become aware of to become worried for all moments of returns on stocks. Subsequently, the variance and mean of returns only were inadequate for full characterization of distribution of returns (Rubinstein, 1973). Hereafter, nonparametric models were developed by researchers that add more moments to typical CAPM. The two-moment model of CAPM has expanded through incorporation of the third moment, fourth moment, skewness and kurtosis, by several authors. Moreover, claimed by Harvey (2000) both kurtosis and skewness are not assessed in developed markets but, they do exist in emerging markets. A noteworthy positive relationship between returns and volatility was establish in those markets which are emerging, with the importance of the coefficient of volatility being wrinkled by the insertion of kurtosis and co-skewness in the model of CAPM. The “Security Market Line (SML)” illustrates the relationship between asset beta and its expected returns. Beta shows relation of surplus return which is expected on a stock compare to the on the whole surplus return of market. The extent to which the asset expected returns are sensitive to the movements of market is explained by beta. When beta is zero, it is considered to be neutral for changes incorporated in market. For decades, unconditional single-factor of CAPM model was accepted by financial analyst. When comparison done with multifactor models of asset pricing it is comparatively simple to use and also regard as efficient in cost. For the purpose of verification, that asset may be fairly priced or not, the CAPM SML can be in use for both analysis of individual security and portfolio analysis. The main proposition of the CAPM is emphasized by Fama (1976), Roll (1977), that when market is at 13 equilibrium, the value-weighted portfolio of market, M, is “mean-variance-efficient”. The efficiency of mean-variance of M says that: (i)𝛽, is the only risk that is needed to explain the return which is expected; beta the incline in the regression of a return on security on the market return, (ii) for 𝛽 risk positive premium is expected.Main point is that proof of (ii) support for CAPM is positive relation between 𝛽 and return to be expected, only if (i) if, 𝛽 be enough to explain expected return. On the other hand, like FF (1992), KSS find that 𝛽 provided the explanation of size in avrage return confirming Banz (1981).Moreover, the prime awkwardness of CAPM is no longer size. Variables that (unlike size) do not appear to be associated with 𝛽(such as earnings/price, cash flow/price, BE/ME, and past sales growth) add even more notably to the explanation of average return provided by 𝛽 (Basu (1983), Chan, Hamao, and Lakonishok (1991), FF (1992, 1993, 1996), and Lakonishok, Shleifer, and Vishny (1994)). The anomalies of the CAPM regarding average return suggest that, if pricing of asset is rational, a multifactor edition of Merton's (1973) intertemporal CAPM (ICAPM) or Ross' (1976) pricing theory of arbitrage (APT) can provide an improved explanation of average returns. The excess return on market of the CAPM is a relevant risk in many multifactor substitutes, like the ICAPM and Connor's (1984) equilibrium side of the APT. Thus, proof of a positive relation between, and expected return does not favor the CAPM over these alternatives. This point has been illustrated by three-factor model of Fama and French (1993, 1994, 1995, and 1996). As compared to CAPM this model provides an improved description of normal returns, and it captures those anomalies of average-returns that CAPM missed. 2.2 Fama and French 3 Factor Model: A different perspective of asset pricing has been presented by models of Fama and French (1993). The aim of their study is to 14 explain excess returns on portfolio related to three risk features. These risk factors are excess return on market portfolio, the difference between the portfolio of small stocks having excess return and portfolio containing big stocks having excess return, difference between portfolio’s surplus returns of high B/M ratio and portfolio of low B/M. They uncover that construction of portfolios is for imitate factors of risk that are associated to factor of market, size and value of stocks and stocks returns are notably effected by these factors. Their model claimed to be successful for capturing the average returns of crosssection on U.S. stocks. Difference between returns of stocks on stock exchange of New York (NYSE) and (NASD) have been explained by Fama et.al (1993). Returns of similar size stocks on both NYSE and NASD vary; returns on stocks of NYSE are much higher in the duration of testing. The difference is explained by using Fama and French model of three factors. Reason for the variation on returns of same size stocks demonstrated by their analysis and they come up with the following justification that risk of stocks is different, Fama and French model of three factors captured it. It is argued by Fama et al. (1993, p.37) that stocks having high level of sensitivity be likely to be those firms who have steadily deprived earnings, this results in low prices of stocks and therefore their ratios of B/M is high. On the other hand stocks having low sensitivity have a propensity determinedly elevated earnings, it direct to low ratio of B/M. They come up with this conclusion that ratio of B/M is the mainly central factor of risk that illuminates the difference between returns of NYSE and returns of NASD stocks. A test has been conducted by FF (1995) to check that discrepancies that come on prices of stocks, in relative to size effect and effect of BE/ME reveal the deviations comes in firm’s earnings. High ratio of BE/ME reports 15 poor earnings and if BE/ME is low it indicates high earnings if constant with rational pricing reported by Fama and French (1995, p.131). Their model was tested on AMEX, NYSE and stock market of NASDAQ. It is reported, size and factor of market in earnings enlighten the factors of returns but no relation was found by them between value factors and factors of returns and earnings. One more research on U.S data was provided by Fama and French (1996). The argument they given was that when model of three-factor used anomalies missed by CAPM widely disappear. Formation of portfolios with respect to cash flow/price, earnings/price and sales growth is tool for explaining the well-built patterns in returns observed. For the period of 1963-1993 model of Fama and French was tested on NASDAQ, NYSE and AMEX by Daniel and Titman (1996). The findings of their test were not in the support of FF typical model. Their conclusion was that there does not prevail any relation between Fama- French three types of risk factors and expected return. For the period of 1981-1993 model was tested on listed stocks of “Italian Stock Exchange” by Aleati et.al (2000). They find that in the returns of stocks only variables associated with interest rate changes and market index are priced. They wrap up that ratio of price-to book is dependent on the period of estimation. The study of Daniel and Titman’s (1997) was extended by Davis, Fama and French (2000) they tested the model from period of 1929 to 1997. The results of their study were contradicting from Daniel and Titman. Study done by them was in the support of model of FF. In India Sehgal and Connor (2001) scrutinize the model of FF empirically. Results of this study were in the support of model. They accepted this fault that there are several unanswered questions in the study done by them. One of unanswered question was that whether value and size factors are persistent in reporting 16 the risk for a portfolio of wider range. Validity of this model was also tested by Güzeldere and Sarıoglu (2012) on ISE-100 index from year 1999 to 2011. Panel data was used to analyze monthly returns. Results of this study were also in the support of the FF model considering three main factors. Hence conclusion comes out in the favor of this model as it seems to be more powerful and best as an alternative for CAPM. In financial sector efficacy of this model was tested by Hamid et.al (2012) by using returns of portfolio. Stocks of “Karachi Stock exchange” held in Pakistan were used. Six portfolios were taken for the implication of Model of FF in this study. Data on monthly basis was taken related to 20 banks for time period of five-year from period of January 2006 to December 2010. Results of this study showed that model is appropriate for financial sector presiding in Pakistan’s economy. 2.3 Firm Size (SMB), Firm Value (HML) and Stocks Returns: Relation between characteristics at firm level and returns on stocks is extensively investigated after 1980 in developing and developed countries. A significant link between specific factors of firm and returns on stocks suggested by findings of literature in examined countries. The effect of size was first recognized by Reinganum and Banz (1981) who come to know that premium is present for return on stocks of small size for the period of 1936-1975 for the stocks which are listed on NYSE. This effect was later also confirmed in Australia and USA by Stambaugh and Blume (1983) and Brown et al. (1983) respectively. The effect of BM was firstly renowned in (1985) by Rosenberg et al. Premium was found by them on returns of those stocks who have high ratios of BE/ME in stock market of US. Such value premium or effect of BM was later established in USA by Davis et al (1994) and outside USA by Capul et al, (1993) and Chan et al. (1991).Their 17 findings reveal that size of firm and BE/ME have significant effect on expected returns on stock, positive and negative, respectively. Developed countries were covered in study of first group. According to FF (1992) there is no power of market beta for explanation of variation comes in returns of stock in U.S while selecting firms from non-financial sector, hence they find that size of firm and equity ratio of book to market can captured the variations that come in cross – sectional returns on stock for the time of 1962 to1989. It is reported by Fama and French (1992) that premium related to risk for size and BM variables are simply computable, drastically with negative and positive sign. Three factor model of FF (1993) was empirically examined by Eleni and Andreas (2004) they use data of Japan from 1992 to 2001 time period. The conclusion reveals noteworthy relationship among specific three factors and returns to be expected on stocks in the Japanese market. Additionally, it undoubtedly shows that there is only factor of market which have mainly explanatory power for explaining the variation comes on returns of stock returns. The expressive power of the factor of size (SMB) is more dominating than the explanatory power of value factor the BE/ME (HML) it is true for those portfolios which consist of small size stocks and vice versa for testing portfolios of big size stocks, Bryant and Eleswarapu (1997) from period of 1971 to 1993 and also Pinfold et al (2001) from duration of mid- 1993 to 2001March, acknowledged a strong effect of BM but a very weak effect of size on stocks of US. Strong effect of size and BM was described by Vos and Pepper (1997) over the time period of 1991-1995, whereas their study was replicated by Li and Pinfold (2000), over the time period of 1995 to June 1999, and hence they did not find any evidence of book to market effect. 18 In the market of Japan Chui and Wei (1998) and Daniel et al. (1997) find that for the explanation of variations come in stock returns book-to market of equity plays a considerable role. This relationship was investigated by second part of studies for mostly developing market also includes stock market of Sri Lanka. When use approach of multifactor model for Malaysia by Veeraraghavan and Drew (2002) evidence reported by them for premium on factor of value and size. They account that for Malaysia, factors recognized by FF (1993), enhanced the explanation of variations come in stock returns. In “Shanghai stock market” size effect and less persistent BM effect was reported by Drew et al. (2003). Regression model of Fama-Macbeth (1973) was applied by Senthilkumar (2009) on particular industries of India for inspecting the performance of stock returns in ratio of book to market and size. They come up with no effect of size while considering overall markets and a noteworthy effect of book to market in all of related groups. When test was applied on both variables, there is less significant negative relationship between size of firm and average return; when book to market included in selected stock returns of India it seems to take in the role of size. The two most popular factors were investigated by Anuradha (2007) on returns of stocks listed on CSE and reports the negative relation of size with respect to return and positive relation of BE/ME. It is also reported by Mahawanniarachchi, (2006) that a significant negative relationship found between factor of size and individual returns on stocks and positive relationship between BE/ME, factor of market and single stock return. Auxiliary, it is reported that factor of size, market factor and BE/ME factors have substantial descriptive powers for the explanation of stock return in Sri Lanka. Chaturika Nimal and Seneviratne employed model of three factor (FF) (1995) for investigating the size and BM factors for explaining equity returns and 19 earnings for the stocks of CSE. Outcomes of the study suggest that the earnings of corporation are linked with three factors, but reliable link doesn’t provide by it among the performance of factors in earnings and returns on stocks on CSE. Also, they recognize that factor of market has more capability for predicting the stock returns of future in comparison to size and value on CSE. The size effect provides that firms having small capitalization of market reveal high returns on average which notably exceed the returns of big cap firms. The effect of BM indicates that if ratio of B/M is higher then returns on average will be higher for such stocks and also vice versa. Premium on such high B/M stocks is known as premium of value. Analyses on features of firms having high ratio of BM and firms having stocks of low B/M is done by Fama and French (1995). Firms with high ratio of BM found in distress persistently and other with low ratio found continual profitable. Study reports that the higher returns of those stocks whose BE/ME is high can be attributed to holding of less profitable and riskier stocks. Study further reveals that HML in model of three factor is used as substitute for relative distress. Financially unsound firms having persistently low earnings have a tendency to to have high ratio of BM and on HML have positive slopes, financially sound firms with higher income earnings lean to have low B/M and their slopes on HML are negative. Dennis, Perfect, Snow, and Wiles (1995) provide support to Fama and French’s results and confirm prior findings that for any given size category, average annual portfolio returns increase as the BE/ME increases and, for any given BE/ME category, average returns decrease as size increases. The BE/ME effect is found significant for different holding periods and a trading strategy based on BE/ME and size could have been profitable. The implication of their study is that investors can significantly outperform the market if they select small20 size-high-BE/ME securities for their portfolios during the period. Fama and French (1998) provide additional valuable out-of-sample evidence by testing the FF three factor models in thirteen different markets over the period 1975 - 1995. Study reports that 12 of the 13 markets record a premium of at least 7.68% per annum to value stocks. Seven markets show statistically significant BM/ME betas. However, Daniel and Titman (1997) do not agree with Fama and French (1992, 1993, and 1996). Daniel and Titman (1997) investigate the impact of factor loadings on stock returns for the period 1973 –1993 and report that expected returns are not a function of loadings on the Fama and French risk factors. They argue that it is the covariance between high book-to-market ratio stocks that leads to similar properties rather than a common risk factor. Kothari (1995) MacKinlay (1995) and Loughran (1997) see the matter in from a different perspective. It is argued by them that a considerable premium portion is because of biasness of survivor and snooping of data. The source of data for BE contains firms unevenly and those firms have high ratio of BE/ME and they survive in distress so the return on average for such firms is overstated. The hypothesis regarding snooping of data speculates that researcher’s desire of searching for variables that are related to average return, may lead to identification of anomalies that are present specifically in the sample and are used for identification. However, several studies consider it a weak argument and dismiss the biasness of survivor and hypothesis about snooping of data. Halliwel et al. (1999) tests the Fama and French (1993) model in Australian equity market and reports the presence of some premium on small sized and high book-to-market ratio stocks. 21 However, study reports that explanatory power of Fama and French three factor model is not significantly higher than traditional CAPM. Halliwel et al. (1999) do not find any evidence for the decrease in size sensitivity, given a transition from low to high book-tomarket ratio stocks. This behavior is found inconsistent with Fama and French (1993) that reports the presence of a tendency for size sensitivity to fall when moving from lower to higher book-to-market portfolios. Model of Fama and French was tested by Sehgal and Connor (2001) on Indian market and they found that three factors i.e Size, factor of BM and return of market explain more powerfully the mean returns of cross- sectional stocks as compared to typical asset pricing model (CAPM) that lies upon only one factor that is market returns. When model of Fama and French was applied on Australian data by Faff (2001) for the time period of 1991 to 1999 results strongly supported this model and accepted the high explanatory power of three factors for average returns. Existence of significant negative relationship was evidenced by this study which is in actual contradicts to expected relationship that is premium should be positive for stocks of small size. Faff (2001) therefore reported that his study results seem to be consistent with other reverse size effect evidenced recently. Comparison of CAPM and Fama and French model of three factors was done by Veera raghavan and Drew (2003). In this study descriptive power of both models was challenged for markets of South East Asian and presence of value and size premium was reported in such markets. This study reports that variations incorporated in returns for those markets can well explained by FF model of three factor. Premiums demand by investors are actually compensation for bearing certain type of risk and model of asset pricing based on single factor is unable to explain this type of 22 premium argued by Drew and Veera raghavan (2003).In equity market of Australia Gaunt (2004) execute test out of sample for the time period of 1991 to 2000 and concludes that for small size companies having low BM ratios beta tends to be higher. So after a long discussion on size of firm and value of firm we come up with following hypothesis. H1: There is a negative relationship between firm size and stocks returns. H2: There is a positive relationship between book-to-market value of equity of a firm and stock returns. 2.4 Financial Distress and Stocks Returns: Stocks of distressed firms perform below standards and their underperformance becomes an anomaly that comes in the form of twist. High returns on “value stocks” that are anomalous is explained by several researchers and Fama and French (1996) by assuming that such firms are moving towards bankruptcy: due to incorporation of bad news in market their prices effected and move towards down. And risk of bankruptcy is somewhat that markets should quite dislike. Losses that may occur due to default can be in the form of systematic risk for lot of reasons, and the collective default rate is rather volatile. For the returns of shares bearing high risk this argument provide support for the prediction of risk premium for default to be positive. Financial distress can be defined in several contexts but in simple words it is defined as “the firm’s inability to pay financially obliged liabilities as they mature”. Different perspectives of financial distress were pointed out by Beaver (1966) for the very first time. Every form of financial distress depend on the kind of event occurring just like bankruptcy, default of bonds, an account of bank which is overdrawn or failure to pay dividend on preferred stock all these characterize the operational type of financial 23 distress. Financial distress is also reported by Baldwin and Mason (1983), Andrade and Kaplan (1998). Interpretation of financial distress is described by these authors as critical event which occur and it occurrence let company financial soundness in trouble and to get rid of this situation certain strategies are required. Another definition was given by Hendel (1996) according to which chances of firm going bankrupt depends on the extent of liquid assets it have and how much credit is available. Dichev (1998) was the first to show that prediction does not bear out and that the performance of high risk shares is actually very bad. He make groups for CRSP such sample which is Compustat matched including time period from 1981 to 1991 then grouped this sample into portfolios on the basis of degree of bankruptcy for this purpose he use ratings of ohlson (1980) and Altman (1968). Mean returns for high risky firms are calculated and then did comparison with average and less risky firms. Firms’ performance with high level of risk of bankruptcy is obviously worst when comparison done with both indicators. A strategy of trade that goes for long time in portfolio of equally weighted firms where the bankruptcy risk is low and for short time in those firms where risk of bankruptcy is high earns almost on monthly basis 1.17% and on annual basis 22.4%. By busing regression confirmation of results are made. Another evidence of negative relationship between distress risk and returns is find by Griffin and Lemmon (2002). For distress proxy is used by Ohlson's (1980) O-score, relationship is still negative even non stationary structure of regular returns is corrected by means of 3 factor model of Fama-French. In addition, this relationship is determined by those firms which have low ratio of book to market (BE/ME). When firms with low BE/ME are placed in highest quintile of Ohlson’s O score average return for such firms is only 6.36%, and if we talk about other portfolio around half of mean return and for that 24 period to some extent lower than rate which is risk. Firms which are in subset having high ratio of BE/ME, as these firms are consider as distressed firms their returns are not as lower as expected from their BE/ME. While those firms which are most distressed in given quintile, the difference between estimated return when considering high and low BE/ME firms it is approximately 14.44%. For using the Z score as indicator of Altman (1968) results are strong. On the other hand contrary to above argued literature Vassalou and Xing (2004) presented an evidence which is based on measure of distance-to-default. After the formation of portfolio authors depicts positive correlation between the measure of risk of default and monthly returns for the small size firms as well as those having highest ratio of BE/ME. These estimations are interpreted and repeated by Da and Gao (2005). All the results which are important can be drawn to reversals of first month, showed by them mostly due to problems of data problems with currency stocks, such as bounces of bid-ask and illiquidity. Complete picture showed by two papers which are working papers. Cumulative returns of six months are formed by Garlappi, Shu and Yan (2005) from portfolios which are sorted conferring to risk of default. An unrestricted returns’ negative dependence on defaulting risk has been found by them by using credit rating of standard and poor. Firms in the sub sample having low BE/ME predict negative relationship when they use EDF measures which are generated by data of Moody's KMV. Indicators of default risk present in real world has been used by this study and those indicators were vended to thousands of participants exist in market. New grounds break by Campbell, Hilscher and Szilagyi (2005) when they construct their own indicator of default risk in reduced form which is based on model of logit for bankruptcy and develop concept in broader form for company failure. When firms are 25 sorted into ten diverse portfolios on the basis of their expected default risk, they illustrate that firms which are financially distressed strongly underperform those firms which are financially healthy. If three factor model of Fama- French and CAPM used to correct returns the difference can be magnified. The alpha of three factor for highest percentile of the default risk distribution relates to return of approximately -25% at yearly rate. -15% still exists annually for highest 5%. The portfolio which is long-short and contains 10% stocks having lowest risk of failure and take short 10% stocks having highest risk of failure would earn an enormous 23% annually, and it is almost exactly the similar figure set up by Dichev (1998). Stocks of financially distressed firms bear excess negative premium for this purpose three justifications have been advocated. One possibility can be malfunctioning of markets. Mispricing is described by Griffin and Lemmon (2002) and difference in size is related by them to signs of informational asymmetry. However, such deviation is unexplained that why systematic overpricing lead by informational asymmetry? Two versions advanced by Campbell et al. (2005). One point is this that, markets might be irrational. Specially, financial institutions could have had a prominent an earlier dislike of shares of distressed firms whose return characteristics does not justified them. The shares of financially distressed firms underperform as institution’s market shares go up. Second, inefficiency of markets may exists. The information set they possess may not include the default indicator created by authors, though the authors carefully make sure about availability of its components at time and bias of look-ahead was eliminated by using rolling procedure of estimation. When default indicators of real world are used as they can be used by anyone, effect still exist this is not explained by latter argument. A 26 fundamental explanation centered on risk reported by Livdan, Sapriza and Zhang (2005). Investment of firms reduced by financial constraints. This reduction lowers the level of risk they have to bear risk and therefore their anticipated returns. One important shortcoming of this explanation is: it is unable to explain why distressed firm’s portfolio returns are still small even after making corrections for risk by using CAPM or a three factor model of Fama-French, and why anomaly become more worsen after this correction. Stock returns which are expected for distressed firms should higher and higher risk indicators based on market, such as ratio of earnings to price and ratio of book-tomarket, because conventional insight recommend for these firms risk should high and low values of market values as compared to other firms. So after long discussion following hypothesis can be form H4: There is a positive relationship between distress risk premium and stocks returns. 27 Chapter # 3 DATA and METHODOLOGY 3.1 Modeling Framework Market Based Factors: Market Premium Markey Premium Firm Specific Factors: Market Size Premium Book-to-Market Ratio Value Premium Distress Premium Stock Returns 3.2 Data Sources: The sample consists of 100 companies from different sectors for the period 2005-2012. Data is collected from annual reports published on stock exchange website and BSA (Balance Sheet Analysis) available on state bank of Pakistan website. Availability of data is key concern here so sample excludes the companies for which data is not available and financial companies such as banks and insurance companies because of difference in their capital structure and profits from other non-financial companies. Method of data 28 collection is secondary. This study used secondary data to accomplish research because the data on firm capitalization, firm value, and stocks returns and financial distress is calculated from annual reports. Single factor has been used by CAPM for the purpose of comparison of portfolio with equity market. It has been observed by Fama and French that assets which are categorize in certain classes perform better as compared to others. Hence two factors have been added by Fama and French in CAPM namely value premium and size premium in order to capture the effect of size and market to book ratio, In order to capture these factors, portfolio approach proposed by Fama and French (1993) has been adopted by this study. 3.2 Model Specification. To check the validity of given hypothesis and to find out the relationship between financial distress, firm size and firm value and stock returns the following regression model is proposed 𝑅𝑖𝑡 − 𝑅𝑓𝑡 = 𝛽0 + 𝛽1 (𝑅𝑚𝑡 − 𝑅𝑓𝑡 ) + 𝛽2 𝑆𝑀𝐵𝑡 + 𝛽3 𝐻𝑀𝐿𝑡 + 𝛽4 𝐻𝑀𝑈𝑡 + 𝜖𝑖𝑡 3.3 Variable Description: The above mentioned formula captures the succeeding dimensions: 1. The return which incorporates zero risk. 2. The premium on market beta. 3. Premium on Size effect. 4. Value premium 5. Financial Distress 7. The management impact (𝛽0) 8. Random error 29 𝑅𝑓𝑡 is rate of treasury bill in the start of Month t. 𝑅𝑚𝑡 Basically the market return or the return which is value weighted during Month t for all those non-financial stocks which are listed on stock exchange of Karachi. SMBt = in a given portfolio difference between return on stocks of small size and large stocks. HMLt = the difference between the return on a portfolio of high-book-to-market stocks and the return on a portfolio of low-book-to- market stocks HMUt= The difference between return on a portfolio of healthy stocks and the return on a portfolio of unhealthy stocks. ∈𝑖𝑡 = Error term 3.4 Portfolio Formation: 1. First of all market capitalization of main portfolio is calculated for the end of year June t-1 and then stocks are sorted in ascending order. Now two portfolios are formed first 50 companies moved to small portfolio because they have low market capitalization next 50 are placed in big portfolio as they have high market capitalization. First portfolio named as Small other portfolio named as “Big”. 2. Now Small portfolio is sorted on the basis of book to market equity in descending order. It subdivided into two portfolios one contains first 25 stocks as their median point is 25 and 50 firms are equally subdivided into two portfolio one which have high book to market named as S/H other contains remaining 25 stocks which have low book to market named as S/L. Big portfolio is also subdivided into two portfolios in same manner named as B/H and B/L. 3. In order to incorporate distress effect we use coding those firms which have Z score higher than cutoff are coded as 1 and those firms which have z-score lower than specific 30 cutoff are coded as 0. Then sub portfolios that are S/H, S/L, B/H, B/L are sorted in ascending order on the basis of Z score. From 25 stocks in each portfolio some stocks categorize in small high distress portfolio S/H/D and some moved to small high un distess S/H/UD same happen with B/H and B/L. As there is no median point one portfolio may have 7 distress stocks other may have 12 un distress stocks so we consider only first seven from both portfolios that is lowest number and miss other stocks. Cutoff point set by Altman (2002) is 1.81 its accuracy rate is 84%. According to Altman when a firm have Z-score less than 1.81 its chances of default is high. Finally. Size, B/M and z-score portfolios are then formed at the intersections of the two z-score. P, S, B, S/H, S/L, B/H, B/L, S/H/D, S/H/UD, S/L/D, S/L/UD, B/H/D, B/H/UD, B/L/D, B/L/UD. 3.5 Variable Construction: SMB = 1/4 * [(S/H/D – B/H/D) + (S/L/D – B/L/D) + (S/H/UD- B/H/UD) + (S/L/UD _ B/L/UD)] HML =1/4 * [(S/HD – S/L/D) + (B/H/D – B/L/D) + (S/H/UD – S/L/UD) + (B/H/UD – B/L/UD)] HMU = 1/4 * [(S/H/D – S/H//UD) + (S/L/D – S/L//UD) + (B/H/D – B/H/UD) + (B/LD – B/L/U)]. D stands for distress firms UD stands for un distress firms. How to assess distress risk premium? To measure distress risk or to check which firms are financially distressed and which are financially healthy Z-score has been used as proxy. Accounting ratios which are predefined, Z score can be derived from the weighted sum of such ratios. Altman (1968). Those firms whose Z score lie above specified cut off seldom fail, although the rate of failure is much high in those firms having z-scores lower the cut off. When we use this 31 model of bankruptcy a firm which have calculated z score <1.81 its financial profile will be closer to formerly bankrupt firms, therefore taking itself at an obvious risk of bankruptcy, on the other hand if z>1.81it indicates that firm’s financial position is not at the risk of bankruptcy. Z = 0.012X1 + 0.014X2 + 0.033X3 + 0.006X4 +0.999X5 X1 = working capital which includes current assets- current liabilities/total assets, X2 =earnings which are retained for future/ total assets, X3 = EBIT/ total assets, X4 = market capitalization/total liabilities reported in balance sheet. X5 = sales/total assets. 32 Chapter # 4 RESULTS and DISCUSSION: Table 1: Average Return Difference Time Period 2005-2012 Time Period 2005-2012 Time Period 2005-2012 Time Period 2005-2012 Time Period 2005-2012 Time Period 2005-2012 Time Period 2005-2012 Time Period 2005-2012 Time Period 2005-2012 Average Return Small -0.010119734 Average Return Big -0.006754473 Difference t-stat -0.003365261 0.735952368 Average Return Small -0.010119734 Average Return of Market -0.001836818 Difference t-stat -0.008282916 0.476493392 Average Return Big -0.006754473 Average Return of Market -0.001836818 Difference t-stat -0.004917655 0.669249667 Average Return High -0.015290237 Average Return Low -0.014467349 Difference t-stat -0.000822888 0.940470546 Average Return High -0.015290237 Average Return of Market -0.001836818 Difference t-stat -0.013453419 0.270333776 Average Return Low -0.014467349 Average Return of Market -0.001836818 Difference t-stat -0.012630531 0.288369636 Average Return Distress -0.020893596 Average Return Un Distress -0.006954652 Difference t-stat -0.013938944 0.316368304 Average Return Distress -0.020893596 Average Return of Market -0.001836818 Difference t-stat -0.019056778 0.160323032 Average Return Un Distress -0.006954652 Average Return of Market -0.001836818 Difference t-stat -0.005117834 0.701221971 33 4.1 Average Return Difference: Table 1 reports mean excess returns of small and big capitalization portfolios and difference between their average excess returns. Theory is supported by results, as results reported in this table clearly indicated outperformance of big firms over portfolios of small firms for the time period during which sample is taken. Hence, small capitalization firms are supposed as being more risky than big firms and consequently investors of small firms will claim higher returns for adjusting risk they are bearing. Though, t-stat directs that there is no noteworthy difference between mean returns of small and big portfolio. When comparison of returns of small firms portfolio is done with portfolio of market, value of t-stat shows that there is no considerable difference between small portfolio returns and market portfolio. Results reported in table also specify that portfolio of big firm’s stocks underperforms portfolio of market for the period of sample. Again of t stat indicates that there occurs no significant variance between mean returns of market portfolio and big portfolio. When portfolio of high book to market is compared with low, premium for high portfolios are certainly higher as they are risky enough for investor to demand high returns. Whereas t value is still insignificant which depicts no markedly difference between returns of high and low portfolios. When returns of high portfolio is compared with market return, t stat specifies no marginal difference between both portfolios. For the taken sample time period low book to market portfolio is also compared with portfolio of market here also low portfolio underperforms the market portfolio and t value suggests that there does not exist a significant difference between both portfolios under consideration. In the last distress factor is reported first mean returns of portfolios of distress firms are compared with the average return of un distress portfolio just like small capitalization 34 firms distress firms also perceived as risky and it is clear from the average returns that un distress firms outperforms distress firms and high returns for distress stocks is the justification of their being risky. Finally distress and un distress portfolios are separately compared with returns of market portfolio and results are same as described above for size and value factors.

Mean return of sample companies taken in this study for time period 2005-2012 is 0.012% and average standard deviation of all returns is 0.07%. Mean of all portfolios 35 come negative this is may be due to abnormal behavior of market for the time period of sample taken. Another reason can be overlapping of time period returns of one year effect the all returns when mean calculated. When comparison of small portfolios and big portfolios is did for the purpose of descriptive statistics it is obvious that average return of big market capitalization firms is high as compare to small capitalization firms. One reason may be this that big firms are represented in value-weighted index of KSE, whose performance was well during the period of study except for few years when period of crisis came. Hence, on average companies of small capitalization stocks pay low and their returns adjusted for risk should be high as their profile is perceived as high risky. Statistics of standard deviation indicate that average risk for both small firms and big firms portfolio is nonetheless same, even though the average return of big firms is high in contrast to small stocks. When measures of descriptive statistics for high and low bookto-market firms portfolios is compared, it is showed that portfolios of low book-to-market outperform portfolios of high book-to-market in terms of high mean return. Again, high risk is associated with portfolios of high book-to-market. The regression model has been applied at the confidence interval of 95% to test the validity of the 4 factor model.

However HMU have been found to have insignificant relationship with stock returns with t value of -1.4157and therefore do not explain dependent variable S. The value of R2 in this regression is 0.57 For dependent variable B the relationship of explanatory variables MKT and HML is positive and significant with t values of 9.82946 and 2.776726 respectively whereas SMB and HMU have been found to have an insignificant relationship with stock returns their reported t values are 0.767091 and -0.101 thus no impact on B with value of R2 equals to 0.62. In small cap high book to market portfolio, results validate the presence of market premium, SMB and HML, with positive and significant coefficients for MKT, SMB and HML whereas negative and insignificant coefficient for HMU. The t stat value for MKT is 6.971673, SMB is 9.973006 and HML is 8.731173. It means they explain returns of S/H stocks. However HMU has no relationship with dependent variable with an insignificant t stat value of -1.46404. The value of R2 is 0.78 In small cap low book to market portfolio, dependent variable S/L has been found to be positively and significantly related with independent variables MKT, SMB and HML negatively and significant related with HMU. The t values for MKT, SMB, HML and 42 HMU are 2.664707, 4.419461, 2.258335 and -2.00644 respectively. The reported value of R2 is 0.35. The existence of market risk premium along with size, value, and distress risk factor has been supported in small cap high book to market distress S/H/D portfolio with R2 of 0.63 The MKT, SMB, HML and HMU have positive and significant relationship with t-stat values of 2.841918, 6.020444, 8.571328, 4.01907 respectively. Hence MKT, SMB, HML, and HMU explain the stock returns for S/H/D portfolio. In portfolio small cap high book to market un distress risk factor S/H/UD results support the existence of MKT, SMB, HML, and HMU. MKT, SMB and HML have positive and significant relationship with dependent variable S/H/UD and have the t stat values of 5.25414, 7.563034 and 5.778484 respectively whereas HMU has negative and significant relationship and the reported t stat values is -6.5580. The value of R2 in this regression is 0.722. For dependent variable S/L/D the relationship of explanatory variables MKT and SMB is positive and significant with t values of 3.661682, 5.632639 respectively whereas HML have negative and insignificant relationship with t stat value, -1.14472 and HMU also have been found to have an insignificant relationship with stock returns thus no impact on S/L/D with value R2 equals to 0.44. In small cap low book to market un distress portfolio S/L/UD, results validate the presence of market premium, SMB and HMU with positive and significant coefficients for MKT, SMB and negative and significant coefficients for HMU. The t stat value for 43 MKT is 2.525488, SMB is 7.166555 and HMU is -8.26249. It mean they explain returns of S/L/UD stocks. However HML has no relationship with dependent variable with an insignificant t stat value of, -0.93652.The value of R2 is 0.61. In small cap high book to market portfolio, dependent variable B/H has been found to be positively and significantly related with independent variables MKT and HML, whereas no relationship with SMB and HMU have been found. The t values for MKT, SMB, HML and HMU are 7.747, 0.618605, 2.471419 and 0.0166 respectively. The reported value of R2 is 0.50. The existence of market premium has been supported in B/L portfolio with R2 of 0.43. The MKT has positive and significant relationship with t-stat values of 6.792076. SMB, HML and HMU have insignificant impact with t stat value of 1.122912, 1.672985, 0.3338 for dependent variable B/L and therefore does not explain returns of portfolio B/L. In portfolio B/H/D results support the existence of MKT, SMB, HML, and HMU premium. MKT, HML and HMU have positive and significant relationship with dependent variable B/H/D and have the t stat values of 3.949912, 4.992542 and 2.991722 respectively whereas SMB has negative and significant relationship and the reported t stat values is -3.93177 . The value of R2 in this regression is 0.43 For dependent variable B/H/UD the relationship of explanatory variables MKT and HML is positive and significant with t values of 2.6189 and5.664462 respectively whereas HMU has negative and significant relationship with t stat value, -6.4596 respectively. 44 The SMB has been found to have an insignificant relationship with stock returns thus no impact on B/H/UD with value R2 equals to 0.58.

Results reported in this table hence proved that current returns of portfolios sorted on the basis of four factors are unable to explain the future portfolio return. Rolling beta method is failed in equity market of Pakistan. For two pass regression procedure given by Fama and Macbeth (1973) has been used, where time series linear regression estimate the factor betas are estimated by time series linear regression of portfolio return on a set of common factors. Then, regression which is cross sectional of average return on coefficients or betas estimated prices of risk factor. Main purpose is to assess the significance level of firm specific factors in the second phase ordinary least square (OLS). However, results reveal model of four factor fails to illuminate relationship between MKT, Size, Value and Distress premiums and future 46 returns of stocks returns during the time period of testing. Value of R2 show insubstantial explanatory power of the build model. Hence, insignificant relationship prevails between betas of portfolio and premiums of systematic risk for factor model. As, all of the coefficients for model of four factors are empirically insignificant except few one’s which show substantial value premiums. Hence, value effect to a little extent is useful in forecasting of future returns. The existence of market risk premium along with size, value and distress premium has not supported in P portfolio with R2 of 0.29. The MKT, SMB, HML and HMU have insignificant relationship with t-stat values of 0.952888, -0.11912, 0.916234 and 1.1765 respectively therefore does not explain returns of portfolio P. In portfolio S results does not support the existence of MKT, SMB, HML, and HMU.MKT, SMB, HML and HMU have insignificant relationship with dependent variable S and have the t stat values of 1.463576, 0.593935, 0.602749, -0.8373 respectively. The value of R2 in this regression is 0.18. For dependent variable B the relationship of explanatory variables MKT and HML is positive and significant with t values of 2.747365 and 4.139521 respectively whereas SMB and HMU have been found to have an insignificant relationship with stock returns their reported t values are 0.789674 and -1.96814 thus no impact on B with value of R2 equals to 0.43. In small cap high book to market portfolio, results do not validate the presence of market premium, SMB, HML and HMU with insignificant coefficients for MKT, SMB, HML and HMU The t stat value for MKT is 1.130185, SMB is , 0.788044, HML is 0.121548 47 and HMU is , -0.87915. It means they don’t explain returns of S/H stocks. The value of R2 is 0.13 In small cap low book to market portfolio, dependent variable S/L has been found to be insignificantly related with independent variables MKT, SMB, HML and HMU. The t values for MKT, SMB, HML and HMU are 0.295097, 1.058856, -0.13862 and -1.03704 respectively. The reported value of R2 is 0.12. The existence of market risk premium along with size and distress risk factor has been not supported in big cap high book to market B/H portfolio with R2 of 0.32 The MKT, SMB and HMU have insignificant relationship with t-stat values of 1.421954, 0.578952 and 1.79898 respectively whereas HML has positive and significant relationship with stocks returns and its reported t value is 3.536106. In portfolio big cap low book to market B/L results don’t support the existence of MKT and SMB. HML and HMU have positive and negative significant relationship with dependent variable B/L and have the t stat values of 2.931904, -5.1583 respectively. However MKT and SMB have been found to have insignificant relationship with stock returns with t value of 0.895373, -0.32087. The value of R2 in this regression is 0.34. For dependent variable small cap high book to market distress S/H/D portfolio the relationship of explanatory variables MKT, SMB, HML and HMU is insignificant with t values of 0.689436, 0.188181, 1.025069, 0.270367 respectively thus no impact on S/H/D with value of R2 equals to -0.01. 48 In small cap high book to market un distress S/H/UD portfolio, results does not validate the presence of market premium, SMB, HML and HMU. The t stat value for MKT is0.900049, SMB is -0.44393, HML is 0.528852 and HMU is -1.65492. It means they don’t explain returns of S/H/UD stocks. The value of R2 is 0.07. In small cap low book to market distress portfolio, dependent variable S/L/D has been found to be positively and significantly related with SMB with t value , 2.80035 and insignificantly related with independent variables MKT, HML and HMU. The t values for MKT, HML and HMU are 1.414421, -0.44348 and -1.3903 respectively. The reported value of R2 is 0.16. The existence of market risk premium along with size, value and distress risk factor does not supported in small cap low book to market un distress S/L/UD portfolio with R2 of 0.05 The MKT, SMB, HML and HMU have insignificant relationship with t-stat values of 1.275677, 0.49525, 1.449149, 0.247445 respectively. In portfolio big cap high book to market distress portfolio B/H/D results do not support the existence of MKT, SMB and HML. HMU has negative significant relationship with dependent variable B/H/D and have the t stat values of -2.1201. However MKT, SMB and HML have insignificant relationship with stock returns with t value of -0.34231, 0.131631 and 1.74895 respectively. R2 is 0.06. For dependent variable big cap high book to market un distress B/H/UD portfolio the explanatory variables MKT, SMB, HML and HMU are insignificant with t values of 49 1.253448, 1.861916, -0.17714, -0.95679 respectively thus no impact on stock returns. R2 equals to -0.00. In big cap low book to market distress B/L/D portfolio, results does not validate the presence of market premium, SMB, HML and HMU. The t stat value for MKT is 0.48704, SMB is -0.21631, HML is -0.48589 and HMU is -0.34306. It means they don’t explain returns of B/L/D stocks. The value of R2 is -0.08. In big cap low book to market un distress portfolio, dependent variable B/L/UD has been found insignificantly related with MKT, SMB, HML and HMU. The t values for MKT, SMB, HML and HMU are -0.41211, 0.428375, -0.52707, -0.10046 respectively. The reported value of R2 is -0.04. 4.5 Discussion: The existing literature postulates that distressed firms are small firms, and those having high B/M and these factors are enough to capture the risk of distress factor that is overlooked by market factor. Though, the pricing of default risk in equity returns of Pakistan, which is explicitly focused by this paper, has been inefficiently addressed to date. We use method of z-score, a measure which is accounting-based and it is known to be a strong indicator of financial distress from which firms suffer, it can be used as proxy for bankruptcy risk. Results we find opposing to the factor of distress hypothesis, stocks of distressed portfolios make lower returns as compared to portfolios of non-distressed firms. Same results concluded by Dichev (1998) on data of sample taken by him. It is argued by Fama 50 & French (1995) that only a small share of financially distressed stocks in reality go bankrupt, while vast majority still surviving, this can be a strategy that investors invest in distressed stocks to earn greater returns. However, proposed study empirically find that on average proportion of firm is 18 which are reported as distressed firms for the period of sample and these firms go bankrupt as share of default firms is sufficient enough for driving the realized return down to implement the strategy of making investment in stocks of distressed portfolios. Vassalou & Xing (2002) and Griffin & Lemmon (2002) predicted that effects of size and B/M are determined by stocks of high risk of bankruptcy. However, they make sorting in sequence and results might be sensitive to the procedure of sorting. Further, Vassalou & Xing’s model of contingent-claims for assessing likelihood of bankruptcy has variable of key interest size, the proposed study also apply sorting but to identify distressed firms stocks are sorted on the basis of Z score and its evident from results of our model of zthat for small cap firms having high book to market and financially distress portfolio S/H/D size premium, value premium and distress premium is note ably significant which relate our results with previous literature that small firms are risky and they are more vulnerable to financial shocks they don’t have stable financial structure and due to their riskiness investor claim high risk adjusted returns. It also indicate that distress premium is priced in equity Market of Pakistan. Table 1 reports Statistical properties of the variables of four factor model. Table 1 indicates that average return on market portfolio is high as compared to other portfolio but negative it may be due to one reason that equity market of Pakistan perform below 51 standard for the time period of 2005 to 2012. Average return of big portfolio is high in comparison to low portfolio which means value stocks (having high B/M) outperformed growth stocks. On average stock returns of big portfolio are high than stocks of small size which mean negative SMB. In Table 2 it is indicated that portfolios of B/H and S/H have high returns and are high risky. However, B/H found to be efficient as it offers greater returns at low risk level. In segments of small and big stocks high B/M outperformed low B/M stocks. Returns of B/L are low then B/H, though it is supported as empirically evidence on subject is that stocks of high cap firm earn low returns and stocks having low ratio of book to market underperform in relate to stocks having high ratio of book to market. (Stattman, 1980). Standard Deviation is supporting justification of risk based on higher returns for all portfolios. If we make analysis of multivariate regression results it is worth to mention here that size premium is find significant for portfolios of all stocks except B/H, B/L and S/H/D. Therefore, factor of SMB cannot ignored whenever to make decisions at economic level. Though market premium is significantly positively related to returns of all portfolio and this is constant with conventional model of asset pricing. Therefore, it is perceived that factor of market return can expressively explain returns of equity but it is unable to fully explain the returns. So size, value and distress premium captures the returns which are ignored by market factor. 52 Chapter 5 CONCLUSION 5. Conclusion: The basic motive behind that study is to find out the working mechanism of asset pricing keeping in view the relationship between size, value and stocks return in the capital market of Pakistan. For this two broader categories of factors are used named as Market specific Factors and Firm specific factors.In market specific factor Market Premium is taken under consideration for the Firm specific Factors Size Premium, value Premium, Profitability Premium, Investment and free cash flow Premium are taken under consideration.After the deep study the best suited model for this study was Fama and French model.Various tests were performed on the collected data, as it was five factor model. There were four objectives of this study. First was to investigate persistence of already tested size and value anomalies in emerging market of Pakistan. Second was to investigate the impact of profitability premium (RMW) on excess portfolio returns. Third was to examine the impact of investment premium (CMA) on excess portfolio returns. Fourth was to study whether the free cash flow anomaly exists as a risk effecting the excess portfolio returns in the context of Karachi stock exchange 53 This study explores the mechanism of asset pricing by examining the relationship between size, value, distress and stocks returns in equity market of Pakistan for time period of June 2005 to June 2012. For this purpose monthly prices of stocks are used. To discover the combined effect of four factors namely market premium, size premium, value premium and distress premium a new factor HMU has been added to three factor model of Fama and French. Testation of this new four factor model has been done in this study. The main objective of this study was to check whether distress risk priced in equity market of Pakistan or not. In this study, we show that the distress risk-return relation is dynamic. In the cross section of stocks, recent innovations in distress risk are negatively related to subsequent return. We explore the relation between distress risk and the size and book-to-market anomalies. We find that distress risk is a plausible explanation of the anomalous returns of the SMB portfolio. However, we find no evidence that distress risk can explain the anomalous returns of the HML portfolio. Distress sensitivity is came out significant and positive for small cap firms and stocks have high book to market. Thus we conclude that there is a financial constraint factor, an identifiable independent common source of economic shocks to firm value. The evidence suggests that financial constraints do affect firm value and that the severity of constraints varies over time. Second, our investigation of the role of financial constraints in asset pricing reveals the surprising result that constrained firms earn lower returns than un constrained firms, a result not explainable using existing asset-pricing models. Third, financially constrained firms do not have returns that are significantly more cyclical than average. Consider the following explanation of the size effect in asset pricing, the fact that small firms have high returns and have common return variation. Small firms have more precarious access to external 54 finance and are more exposed to variations in credit conditions and to macroeconomic fluctuations generally. Therefore, investors need to be compensated for holding small stocks. This explanation is attractive because it provides an economically meaningful story that is consistent with the following different pieces of evidence: Small firms have high returns, are more cyclical, have higher loadings on monetary policy, and tend to be more financial constrained than other firms. Unfortunately, the results in this article suggest that this explanation is wrong. Unlike small firms, financially distress stocks do not earn high returns and are not particularly exposed to macroeconomic risk or credit conditions. Distress stocks outperform un distress stocks. Distress factor include credit worthiness analysis of firms for financial and non-financial institutions, identification of undesirable investment risk for portfolio managers and individual investors and to aid in more effective internal and external audits of firms with respect to going-concern considerations, among others. Size premium is found significant for all portfolios except big high, big low and big high distress. So size premium also hold in Pakistani market. However, value premium show inconsistency. Average returns of portfolios sorted on the base of Size indicate small portfolios have high risk as well as high returns but average of small and big portfolios returns reports contradictory results. It can be result of anomalous behavior of market in period of 2005 to 2006. The main findings of the study reveal that four factor model markedly explains the returns of portfolios. Premiums for distress come negative, so we cannot get the accurate results of second pass regression are contradictory to our hypothesis. Griffin and Lemmon (2002) also find a negative relationship between financial distress as proxied by Ohlson's (1980) O-score and subsequent returns, even after correcting for the stochastic structure of returns by means of a Fama-French 3 55 factors model. In addition, they show that this relationship is driven by firms with a low book to market (BE/ME) ratio. Garlappi et al. (2005) find that the negative relationship between probability of default and returns is restricted to the firms with low BE/ME ratio. Campbell et al. (2005) also observe a maximum underperformance for low BE/ME firms, although underperformance is also high in the subset of the firms with the very highest BE/ME ratios. There-fore, decision makers should wisely account for these factors in making any decisions about investment or from which sources financing is possible and about valuation. However results of second pass regression are substantially insignificant for Pakistani market which depicts that current coefficients of four factors that are market, size, value and distress are unable to explain the future returns, though four factor model and conventional CAPM is significant as they explain the current stock returns of equity market of Pakistan. 5.1 Research Limitations: This study has some limitations just like other empirical studies which can consider as point of start for future research. The availability of data is key concern here and this accessibility designed this study for only Pakistani market. Unfortunately this study did not have opportunity to take under consideration other markets in order to assess that interpretations drawn from this empirical study can also applicable on different markets and samples. Limitation of time period is also noteworthy. In this study only model of three factor is taken now five factor has also come. 56 5.2 Future Directions: One way to extend this study is to examine the relationship between risk of financial distress and returns on stocks in an economy under two different states one is in good state and other is bad. This study assume that non-diversifiable risk specifies only sensitivity of single stock or stocks in the form of portfolios to the movements of broad market. However systematic risk can be define in form of whole economy and its sensitivity towards shocks which are macroeconomic in nature to check whether this new model apply provisionally on the economy’s state. Another expansion can be to build a model in which interrelation between risk of financial distress and recovery from this situation can be investigated. The most exciting challenge for researchers in the area of valuation of corporations can be integration of individual volatility with discount rate for the purpose of valuation of those stocks which are distressed. This field of financial distress in corporations is still underdeveloped area of empirical and academic research and it call practitioners and scholars to keep investigating this new interesting and encouraging arena of modern finance.
