We find that professional connections not only benefit analysts, but also connected executives’ firms and analysts’ brokerage houses. Analysts with professional connections to firms have more accurate earnings forecasts, informative stock recommendations and are more likely to become all-star analysts. Connected analysts are more likely to follow departing executives and initiate research coverage on their new firms. Finally, buy-side investors allocate greater trade commissions to brokers employing professionally connected analysts. The evidence is robust postRegulation FD indicating that management access remains important to capital market participants.

Introduction Sell-side equity analysts collect, decipher and disseminate complex information to their buyside and retail clientele. The extant literature indicates that analysts are important information intermediaries in capital markets as their research output are used by investors in generating earnings expectations, evaluating firm performance and forming investment decisions (Francis, Lafond, Olsson and Schipper, 2005; Loh and Mian, 2006). While analysts rely on a wide array of information channels in developing insights about their coverage firms, superior access to management has long been recognized as one of the most important and useful conduits of information available to analysts (Chen and Matsumoto, 2006; Soltes, 2014). Survey evidence from analysts in Brown, Call, Clement and Sharpe (2014) and Institutional Investor’s annual poll of buy-side institutions suggest that maintaining strong relationships with firm management is a critical component of their job. 1 In this paper, our focus is on management access obtained through a distinct and economically important information channel—professional connections. Considerable evidence illustrates that professional connections are among the most frequently used relationships in financial markets and have a significant impact on the transmission of business-related information and decision making (e.g. Kuhnen, 2009; Stuart and Yim, 2010; Engelberg, Gao and Parsons, 2012; Duchin and Sosyura, 2013). Business ties do not mandate homophily between two parties, are developed in a professional setting and considered more formal compared to social connections (i.e., educational ties, religion, nonprofessional organizations) representing a unique aspect of capital market relationships (Hwang and Kim, 2009; Fracassi and Tate, 2012). However, the literature is silent on the impact of business ties to analysts. 2 We conjecture that analysts exploit professional networks within their coverage portfolio to cultivate superior access to management thereby providing them a competitive advantage in acquiring and/or processing information. We also investigate the benefits of professional connections from the perspective of connected executives’ A 2013 global survey of 693 CEOs and CFOs conducted by the Bank of New York likewise suggests that of the total time spent with the investment community about 20% is with sell-side analysts. See Bank of New York Mellon, Global Trends in Investor Relations: A Survey Analysis of IR Practices Worldwide, 9th edition, 2013. 2 Conversations with several Directors of equity research (DOR) and sell-side analysts confirm the view that professional connections are an important information channel. In fact, one DOR indicated that analyst connections are a factor they take into consideration when making hiring decisions. 1 2 firms and analysts’ brokerage houses providing a more complete picture of the importance of these connections in the capital markets. 3 Our sample consists of a large and unique dataset of hand-collected pre-analyst employment backgrounds merged with biographical information for senior officers and directors obtained from Boardex of Management Diagnostic Limited (Boardex). A significant advantage of pre-existing professional connections is that they have been formed ex ante, therefore their formation is not related to company-specific information being transferred eliminating reverse causality concerns. We define a professional connection as one where an analyst and a member of a coverage firm’s management are directly connected through overlapping employment at the same firm prior to the analyst becoming a sell-side analyst or where an analyst is indirectly connected to management through “intransitive triads” created by direct professional connections (e.g. Engelberg, Gao and Parsons, 2012; Ishii and Yuan, 2014; Bramoullé, Djebbari and Fortin, 2009; Pool, Stoffman and Yonker, 2014). In our sample of 94,185 forecasts on 3,413 firms by 2,467 analysts between 1993 and 2011, we find that earnings forecasts issued by analysts with professional connections to management in the coverage firm are more accurate than forecasts of analysts without such connections. The mean relative accuracy of analysts with professional connections is 2.7% higher compared to analysts lacking such ties after controlling for other factors shown in the analyst literature to explain crosssectional differences in earnings forecast accuracy. By way of comparison, all-star analysts generate 2.5% more accurate forecasts. In addition, the inclusion of alternative potential channels of management access (i.e., investment bank affiliation, optimism, alumni networks, geographical locality) leaves our results nearly unchanged, lending support to the notion that professional connections represent an economically important and distinct information channel exploited by sellside analysts. We examine the impact of Regulation Fair Disclosure (Reg FD), which was a regulatory shock enacted in August 2000 prohibiting selective disclosure of private information. This regulation has generated a tremendous amount of research with mixed findings. Our results are robust pre- and post-Reg FD providing evidence in favor of analysts’ views that management access remains important in a post-Reg FD world (Brown et al., 2014). We acknowledge that business connections are only one of several forms of management access. Educational links (Cohen, Frazzini and Malloy, 2010), optimistic research on client firms (Gintschel and Markov, 2004; Chen and Matsumoto, 2006), investment banking affiliation and geographical proximity (Malloy, 2005) might be among other means to get privileged access to management. However, as we show in Appendix A, the correlation between professional connections and these alternative channels is very low. For instance, the correlation between alumni links and professional connections is only 0.05. 3 3 Akin to better earnings forecast accuracy, superior access to management through professional connections may also allow an analyst to issue more informative stock recommendations. We find stock upward revisions issued by analysts on coverage firms where professional connections exist elicit a 0.44% greater abnormal market reaction compared to upgrades issued by analysts without such connections. The impact of professional connections on stock upgrades is smaller in magnitude in the post-Reg FD period, but remains significant. This result is also in contrast to Cohen et al. (2010), suggesting that professional connections are indeed driven by different mechanisms and incentives compared to informal social connections formed through college alumni links. We do not find similar return differentials on analysts’ downgrades. This asymmetric market reaction to upgrades and downgrades is consistent with the interpretation that senior managers may be more reluctant to share insights about their firms during negative business states (Mayew and Venkatachalam, 2012). Our baseline results strongly suggest that professional connections aids analysts’ performance, but it is possible that such information advantage may be correlated with unobservable characteristics. To address this potential issue, we use a natural experiment where there exists a plausibly exogenous shock to an analyst’s professional connection stemming from executive movements in the coverage firm. We identify a subsample of 2,267 (4,373) cases in which an analyst loses (gains) professional connections in the coverage firm emanating from connected executives changing employers. We find relative forecast accuracy of analysts in the coverage firm with professional employment connections deteriorates by 4.8% following the departure of a connected senior manager. Similarly, analysts improve their forecast accuracy by 4.5% when an insider with professional ties to a sell-side analyst joins the followed firm lacking such linkages. Using the same natural experiment of executive job movements employed for earnings forecasts, we find market reactions to connected analysts’ recommendation upgrades are significantly lower (higher) after an analyst loses (gains) a professional connection in the coverage firm. Next, we examine if professional connections are related to analyst career outcomes and lead to an increased probability of being included in Institutional Investor’s annual all-star team. Superior management access of sell-side analysts is consistently ranked among the most important attributes by buy-side institutions that rank the best analysts in each industry. Our findings are consistent with this notion. We find that professional connections strongly increase the likelihood that an analyst will become an all-star analyst. Specifically, a one-standard deviation increase in the log number of professional connections increases the odds of becoming an all-star by 29% for an analyst after 4 controlling for factors previously documented in the literature. Consistent with our other tests, this result is robust in the pre- and post-Reg period. Lastly, we shift our attention to the importance of professional connections for the executive’s firm and analyst’s brokerage house. On the benefits accrued to firms, we focus on a dynamic setting by analyzing analyst coverage initiation decisions in the context of executive movements across firms (Brochet, Miller, and Srinivasan, 2014). For analysts covering departing executives’ old firms, we find analysts with professional connections are significantly more likely to initiate coverage on their new firms. In economic terms, the likelihood of analysts initiating new coverage is 2.1 times more likely when analysts share professional connections with the departing executive compared to cases where no such connections are present. The results hold in the preand post-Reg FD era, suggesting that firms secure research coverage from sell-side analysts through their executives’ professional connections. From the brokerage houses’ perspective, if sell-side analysts assist buy-side clients obtain superior management access to their investment firms through exploitation of their professional connections, then we expect these clients to reward brokers with greater trade allocations and hence commissions on these firms. We empirically test this conjecture using institutional transaction data obtained from Ancerno Ltd over 2000 to 2011 with a sample of 173 unique institutions transacting in 2,968 investment firms covered by 1,947 analysts. The results indicate that the relative commission share of brokers is 0.25% higher on firms covered by connected analysts compared to firms followed by analysts lacking professional connections. This result illustrates the importance of sell-side analyst professional connections in trade allocation decisions of fund managers across brokerage houses. Our paper contributes to several recent strands of literature and should be of interest to both academicians and practitioners. First, our paper makes an important contribution to the large body of research focused on the sources of systematic performance differences across analysts. We document a previously unexplored and economically important source of management access exploited by sell-side analysts through professional connections with executives in coverage firms. Second, our paper sheds further light on the ongoing debate on whether Reg FD has curtailed the benefits of superior access to management or firm management continues to be an important source of information for analysts in the post Reg-FD period. Our findings are consistent with the view among practitioners that acquisition of in-depth public insights on coverage firms through professional connections aids analysts in filling out a “mosaic” of value-relevant 5 information emphasizing the importance of cultivating access to management in the post-Reg FD era. Third, we provide empirical evidence that executives’ professional connections help their firms attract analyst research coverage, furthering our understanding into the factors affecting coverage decisions of sell-side analysts. Analysts’ professional connections to management in coverage firms likewise aid brokers obtain higher trading commission from client buy-side funds. Consequently, our paper is also relevant to the growing literature investigating the determinants of buy-side investors’ commission and trade volume allocation decisions (e.g. broker size (Juergens and Lindsey, 2009); affiliated equity underwriting business (Irvine, 200, 2004); analyst reputation and industry knowledge (Jackson, 2005; Gokkaya, Liu, Xie and Zhang, 2015)). Finally, we add to the emerging literature that highlights the importance of professional networks for a wide range of parties in corporate and financial settings; e.g. investment banking (Cornelli and Goldreich, 2001), venture capital (Hochberg, Ljungqvist and Lu, 2007), private equity (Stuart and Yim, 2010), mutual funds (Kuhnen, 2009; Tang, 2013), mergers and acquisitions (Engelberg, Gao and Parsons, 2012), and CEO compensation (Engelberg, Gao and Parsons, 2013). Our paper is the first to illustrate the implications of professional connections in the context of sellside analyst research. The remainder of the paper proceeds as follows. Section 2 provides a brief review of the literature while section 3 describes the data and provides descriptive statistics. Section 4 presents the main results on analyst output; forecasting accuracy and stock recommendations. Section 5 provides an analysis on career outcomes. Section 6 presents an analysis on the impact of professional connections to firms and brokerage houses. Section 7 provides robustness tests and section 8 concludes. 2. Related literature and motivation Our study is related to at least three different branches of literature. First, our paper contributes to an extensive body of work attempting to identify the main sources of performance differences across sell-side analysts. Second, it sheds additional light on the ongoing debate about whether passage of Reg FD has eliminated benefits accrued to analysts from better management access. Third, our study is linked to research exploring the implications of professional connections in various corporate and financial settings. In this section, we provide an overview of relevant studies in each of these three strands. 6 2.1. What analysts provide to market participants A large component of a sell-side analyst’s job entails gathering and processing information about her coverage portfolio and producing research reports that include forecasts on future earnings prospects and stock recommendations on these firms. The general consensus is that analysts bring valuable new information to market participants through their research as shown by their ability to influence stock prices of coverage firms (e.g. Womack, 1996; Clement, 1999; Gleason and Lee, 2003; Ivkovic and Jegadeesh, 2004; Bradley, Clarke, Lee and Orthanalai, 2014). Academic research indicates that many firm- and analyst-specific attributes including, but not limited to, analyst overall and firm-specific experience, portfolio complexity, forecast age, all-star status, brokerage house reputation, and analyst industry expertise impact analysts’ performance (Stickel, 1992, 1995; Clement, 1999; Jacob, Lys and Neale, 1999; Michaely and Womack, 1999, Gilson et al., 2001; Clement, Rees and Swanson, 2003; Asquith et al. 2005; Ljungqvist et al., 2006; Kadan et al., 2012; Bradley, Gokkaya and Liu, 2014). While analysts gather information from a variety of resources in developing insights about the firms in their coverage portfolio, management of the coverage firms represent one of the key sources of information (Chen and Matsumoto, 2006). Brown et al. (2014) poll sell-side analysts and they concur—management access is a critical component of producing more informative research. This brings up a natural question. How does an analyst gain better access to management? Malloy (2005) examines the role of distance between analysts and coverage firms and documents that geographically proximate analysts provide more accurate forecasts. Gintschel and Markov (2004) and Chen and Matsumoto (2006) find that analyst optimism improves the flow of information between analysts and management. Malloy (2005) and Chen and Martin (2011) investigate underwriting and lending relationships between firms and affiliated banks and find more informative research produced by affiliated analysts suggestive of superior information generation by these affiliated analysts. Cohen, Frazzini and Malloy (2010) show that analysts with college alumni links to directors provide superior recommendations, albeit not more accurate earnings forecasts. These social connections made by sharing common educational institutions indicate that even informal social networks foster information flow between analysts and management. Mayew, Sharp and Venkatachalam (2013) indicate that earnings conference calls help participating analysts receive beneficial information from management. Green et al. (2014a), Bushee, Jung and Miller (2014) and Kirk and Markov (2014) suggest that publicly observable interactions with firm management at broker-hosted conferences, industry conferences and analyst/investor days provide analysts an 7 opportunity to obtain superior information. Christensen, Mikhail, Walther and Wellman (2014) show that sell-side analysts obtain value-relevant private information from their brokerage houses’ political connections. Our paper adds to this growing literature by focusing on professional connections formed through an analyst’s work experience prior to becoming a sell-side analyst. We conjecture that these connections represent a unique and economically important channel through which analysts could get privileged access to management and obtain valuable information they otherwise would not have. 2.2. Regulation Fair Disclosure (Reg FD) and management access There is an ongoing debate in the literature regarding the impact of Reg FD on the benefits of management access to analysts. The main premise of Reg FD is to prohibit selective disclosure of information by management to analysts and institutional investors thereby putting all investors on equal-footing with respect to firm-level information disclosure. Koch, Lefanowicz, and Robinson (2013) summarize the literature and suggest that the evidence on its effects is mixed. While transmission of private material information to analysts may have been eliminated and access to management has become harder to get by the passage of Reg FD, new research suggests that alternative forms of management access continue to help analysts improve their performance in the post-Reg FD era. Perhaps one reason why management access remains important in a Reg-FD world is because acquisition of in-depth public information from management can complement the private information set of an analyst and help them piece together value-relevant information into a mosaic leading to more informative research (e.g. Barron, Byard, and Kim, 2002; Mayew, 2008). Mayew, Sharp and Venkatachalam (2013) and Green et al. (2014a) provide empirical evidence that better management access obtained through participation in earnings conference calls and brokerhosted conferences continue to provide analysts with a competitive information advantage in the post Reg-FD period. Brochet, Miller and Srinivasan (2014) analyze analyst coverage decisions and CEO-CFO movements and find analysts are more likely to move with managers to their new destination firms even following the passage of Reg FD. Our work complements this strand of literature by examining the impact of Reg-FD on professional connections to the coverage firms. 2.3. The value of professional connections An emerging literature in finance and accounting focuses on professional connections and their ability to influence financial decision making and information transfers. Ljungqvist, Marston 8 and Wilhelm (2009) show investment banks tend to co-underwrite stock offerings with banks with which they have long-standing professional relationships. Hochberg, Ljungqvist and Lu (2007) provide empirical evidence on the positive impact of venture capital networks for the quality of deal flow and investment performance. Stuart and Yim (2010) show professional networks of board members impact change-of-control transactions in the private equity market. Garmaise and Moskowitz (2003) analyze informal financial networks of property brokers and show that these networks have a significant impact on the availability of financing to brokers’ clients. Kuhnen (2009) examines professional connections in the context of mutual funds and documents directors of mutual funds and managing advisory firms hire each other conditional on past business connections. Tang (2013) finds that mutual fund managers gain an information advantage through business connections made during prior employment as sell-side analysts. Ishii and Yuan (2014) examine cross-board connections in M&A transactions and illustrate professional connections between boards of acquirer and target firms lead to lower acquirer returns. Engelberg, Gao and Parsons (2012) examine interpersonal linkages between banks and firms, and find that when respective management previously worked together, borrowing costs are substantially reduced. Engelberg, Gao and Parsons (2013) investigate the impact of employment networks in the context of CEO compensation and illustrate that professional connections to executives outside the firm substantially increase CEO compensation. Duchin and Sosyura (2013) identify external professional connections between CEOs and divisional managers and find that CEOs allocate more capital to divisions where the manager and CEO are connected through previous employment experiences. Bertrand, Bombardini and Trebbi (2014) analyze the impact of business connections for lobbyists and documents that lobbyists are more likely to cover issues if they are connected to legislators. Our paper adds to this growing literature by being the first to study the implications of professional connections in the context of sell-side analyst research. 3. Data and descriptive statistics We start our analysis by merging Institutional Broker Estimate System (I/B/E/S) with CRSP/COMPUSTAT and identifying all sell-side analysts who provided at least one annual earnings forecast between 1993 and 2011. We only retain the most recent forecast for each analyst firm year. I/B/E/S provides only the analyst’s last name and the initial of his/her first name. We eliminate observations if multiple analysts share the same first name initial and last name at the same brokerage house. We also remove analyst teams since only the last names of analyst team members 9 are provided by I/B/E/S. This initial screening yields 346,564 forecasts issued by 9,235 analysts on 6,330 unique firms. We next search Zoominfo.com to obtain the full first name of each analyst. With the full first and last name, we search for each analyst on LinkedIN.com to capture employment history. LinkedIN.com is the world’s largest professional network. To ensure we have the right person, the name on LinkedIN.com must reveal employment at the analyst’s employer on the date corresponding to the forecast. 4 If the analyst is not found on LinkedIN.com, we use Zoominfo.com where applicable. For each analyst, we gather past employment information about the names of their former employers along with the corresponding time periods they were there. Appendix A provides a detailed description of our data screening and collection process. Employment history on executives and board members is provided by Boardex, which has been extensively used to examine the role of networks in a variety of academic studies (e.g. Engelberg, Gao and Parsons, 2012; Ishii and Yuan, 2014). We merge these two datasets, which allows us to determine if professional connections exist between sell-side analysts and senior directors in the coverage firm. Specifically, we define professional connections as those where an analyst and a member of senior management at the followed firms are connected either directly through overlapping past employment (primary professional connection) or indirectly through intransitive triads created by primary professional connections (secondary professional connection) (Bramoulle, Djebbari and Fortin, 2009; Pool, Stoffman and Yonker, 2014). We require the formation of professional connections to predate analyst coverage on the connected firm by more than 3 years to ensure that connections between the analyst and followed firm are formed at a distant time eliminating concerns on reverse causality (Engelberg, Gao and Parsons, 2012). Further, there must be a minimum of one year of employment overlap between executives and analysts. 5 Following prior work, we construct an aggregate measure of professional connectedness that sums primary and secondary connections. However, as later shown in section 7, our results do not depend In some cases, we manually match shortened names such as ‘Tom’ for ‘Thomas’ if the last name and brokerage house match exactly and there is no other employee at the firm with a similar name. Otherwise, if the names are not an exact match we purge them from the sample. Name changes from divorce or marriage may be eliminated from our sample if we can’t find an exact match, but there is no reason to believe these situations would systematically bias our results. 5 As an example to the structure of primary professional connections, an analyst (Analyst A) in our sample worked for the Gap Inc. as a Merchandise planner from July 1995 to August 1997. In August 2000 he became a sell-side equity research analyst at Morgan Stanley and began covering Coach Inc. in 2005. An insider (Insider A) at Coach Inc. in 2005 also worked for the Gap Inc. as a VP of Merchandising between December 1994 and 2003 and thus overlapped with Analyst A, creating a primary connection between Analyst A and Insider A. Furthermore, Insider A previously worked at Macy’s Department Stores from 1987 to 1992 as a Divisional Merchandise Manager. Insider B also worked at Macy’s from 1990 to 1997 as Chairman and CEO, overlapping with Insider A. Thus, Analyst A has a secondary professional connection to Insider B via Insider A. 4 10 on this aggregation and hold uniformly across both connection types. To better illustrate the formation of professional connections between analysts and insiders at coverage firms, see figure 1. ***Insert Figure 1 here*** Table 1 reports descriptive statistics on our sample. Panel A presents summary statistics on earnings forecasts. In our sample, 2,467 analysts issue 94,185 annual earnings forecasts on 3,413 unique firms. About 57.9% of coverage firms have at least 1 insider with a professional connection to one of the coverage sell-side analysts. In addition, approximately 35.3% of analysts have a professional connection to at least one of the firms in their coverage portfolios and 24.2% of forecasts are issued on firms where an analyst has a professional connection to a senior member of management in the covered firm. Our sample contains 59% of firms, 24.1% (25.7%) of the total number of annual earnings forecasts (analysts) in I/B/E/S, and 89.1% of the market capitalization of the universe of stocks covered in I/B/E/S. The percentage of professional connections increases through time. Likewise, the percentage of firms and earnings forecasts covered by our sample rises over time. This is most likely because the participation rate on LinkedIn.com has gained traction among professionals coupled with the fact that biographical information on employment histories from Boardex is relatively incomplete before 2000 (Ishii and Xuan, 2014). 6 ***Insert Table 1 here*** Panel B reports analogous statistics on the recommendation revisions sample. With the exception of lower values for the percentage of firms, all other statistics are roughly similar across Panels A and B. In particular, approximately 35.5% of analysts have at least one professional connection to one of their coverage firms and 24.3% of recommendation revisions are issued on these professionally connected firms. 4. Professional connections and analyst research quality: Forecast accuracy and stock recommendation informativeness In this section we examine if better management access obtained through professional connections aids in analysts’ ability to provide more accurate earnings estimates and/or more informative recommendation revisions. This could create a selection bias early in our sample. However, if anything, this bias would work against us finding any results. Nonetheless, to deal with this potential issue we provide two tests. First, we provide results conditional on an analyst having at least one connection with the inclusion of analyst fixed effects, such that we compare forecasts on firms with and without professional connections by the same analyst (Section 7). Further, we examine our results separately pre- and post- Reg FD, which was enacted in 2000. The results post-Reg FD should mostly be free of this bias. 6 11 4.1. Baseline regression models of accuracy Our measure for earnings forecast accuracy is the widely adopted proportional mean absolute forecast error, PMAFEi,j,t (e.g. Clement 1999; Malloy, 2005; Clement and Tse, 2005; Clement, Koonce and Lopez, 2007). PMAFEi,j,t is defined as the difference between the absolute forecast error, AFEi,j,t of analyst i for firm j at time t and the mean absolute forecast error for firm j at time t. This difference is then scaled by the mean absolute forecast error for firm j at time t to reduce heteroskedasticity. By construction, negative values of PMAFEi,j,t represent better than average performance, while positive values indicate worse than average performance. Following the extant literature, we estimate cross-sectional regressions of relative forecast accuracy to control for characteristics that have been shown to impact earnings forecast performance. The key variable of interest is Professional connection, which is an indicator variable that captures if the analyst has a professional connection to management in the followed firm, zero otherwise. We control for analyst general (DGExp) and firm-specific experience (DFExp) as in Clement (1999), Clement and Tse (2003, 2005) and others. DGExp is computed as the total number of years that analyst i appeared in I/B/E/S (GExp) minus the average tenure of analysts following firm j at time t appeared in I/B/E/S. DFExp is the total number of years since analyst’s i first earnings forecast for firm j (FExp) minus the average number of years analysts following firm j has supplied forecasts. Clement (1999) documents that relative forecast errors increase by 0.35% per day, emphasizing the need to control for the forecast horizon. Therefore, we include DAge computed as the age of analyst i’s forecast (Age) minus the age of the average analyst’s forecast following firm j at time t, where age is defined as the age of forecasts in days at the minimum forecast horizon date. Previous studies have shown that analysts covering more firms and industries and also those employed at smaller brokerage houses are associated with lower forecast performance (Clement, 1999; Jacob, Lys, and Neale, 1999). Thus, we include controls for the mean-adjusted portfolio size (DPortsize), number of two-digit SICs (DSic2) in the analyst’s portfolio, and top decile brokerage houses (DTop10). Consistent with Stickel (1992), we further control for reputation of forecasting analysts with all-star status (All-star). Standard errors are heteroskedastic-consistent and double clustered at the analyst- and firm-level. Formally, our model is as follows: 12 PMAFEi,j,t= β0 + β1(Professional connection) + β2(DGExp) + β3(DAge) + β4(DFExp) + β5(DPortsize) + β6 (DSic2) + β7 (DTop10) + β8(All-star) + ε (1) ***Insert Table 2 here*** Table 2 reports the regression results. Model 1 includes our variable of interest and controls. The relative earnings forecast errors of analysts with professional senior management connections are 2.68% lower compared to those of analysts without such ties. The sign and magnitudes of other control variables are similar to previous work on analyst forecasting performance. For example, analysts’ forecast accuracy improves with general and firm experience, brokerage resources and allstar status, but gets worse the more complex the analysts’ portfolio and the older the forecast. Note that the economic importance of professional connections on forecasting performance is at least as large as any of these other ubiquitous factors. To put this result in perspective, all-star analysts produce 2.52% more accurate earnings forecasts than non-star analysts. Bradley, Gokkaya and Liu (2014) document that sell-side analysts with related industry work experience are associated with more accurate forecasts. They suggest this is primarily due to a better understanding of industry fundamentals, such as the impact of macroeconomic and microeconomic factors on the operations and financials of followed firms. Since professional connections may be correlated with this effect, we include a control for Related experience which equals one if analyst i makes forecasts on a covered firm related to her previous work experience, zero otherwise. Specifically, related experience equals one if an analyst’s previous employer and covered firm shares the same 4-digit Global Industry Classification System (GICS) code, zero otherwise. While the coefficient on related industry experience behaves similar to that reported in Bradley, Gokkaya and Liu (2014), our main results on professional connection remain intact. Another legitimate concern with our measure of professional connection is that it could be correlated with alternative channels of management access channels. To rule out this possibility, models 3 and 4 explicitly control for these channels. We control for firm-analyst investment banking affiliation (Affiliated), social connections between analysts and management through shared education backgrounds (Education connection), analyst optimism (Optimism), and analyst locality (Local). Because we lose 23% of observations when we consider the distance between the firm and analyst’s location, we estimate this model separately to retain as many observations as possible. The economic and statistical significance of professional connections continues to be strong, suggesting that we have indeed identified an economically important and unique information channel. 13 A related explanation for our results is that analysts might simply devote more effort towards professionally connected firms to honor their relationships with connected managers, explaining the superior earnings forecasts generated on such firms. We include controls for the number of forecast revisions (No of forecasts) (Jacob et al., 1999) and issuance of no forecasts over the following fiscal year (Drop coverage) (Chen and Matsumoto, 2006) as measures of analyst forecasting effort in model 5 of Table 2. While the accuracy of earnings forecasts are positively related to these proxies of analyst effort put forth by the forecasting analysts, the marginal impact of professional connections on analyst performance remains robust. 4.1.2. Professional connection mechanism Having documented the impact of professional networks in capturing privileged access to senior management, we next investigate the mechanism(s) through which information is transferred along these networks. Professional connections may help an analyst obtain easier access to private material information on coverage firms’ operations, and/or forthcoming earnings announcements. On the other hand, an analyst may simply exploit her professional connections to collect valuerelevant in-depth public information that would complement her private information set leading to more informative research. This may emanate from superior identification of coverage firm managements’ quality or style-related to strategic decisions, operations and performance (Bertrand and Schoar, 2003; Brochet, Miller and Srinivasan, 2014) and/or better interpretations of signals gleaned from connected managers’ body language and vocal cues during one-on-one interactions (Mayew and Venkatachalam, 2012). In order to distinguish between these two main explanations, we split our sample into preand post- Reg-FD periods and analyze the extent to which the passage of Reg FD has impacted the benefits accrued from professional networks. The enactment of Regulation Fair Disclosure (Reg FD) in October 2000 materially impacted information flow from firm management to analysts by prohibiting selective disclosure of material information. In the context of our paper, Reg FD represents a significant regulatory shock presumably eliminating the flow of private information through professional connections. ***Insert Table 3 here*** Comparing the coefficients on professional connections in model 1 (pre-Reg FD) to model 6 (post-Reg FD), the value of management access through these connections declined after Reg FD passage, but has not been eliminated. For instance, analysts with professional connections are 8.84% 14 more accurate pre-FD and 1.95% more accurate post-FD. Other variables in the remaining models behave roughly similarly across estimations. These results indicate that while Reg FD likely has eliminated the benefits from private information flow to analysts through professional connections, these connections still remain important for analysts’ performance in the post-Reg FD era, suggesting that preferential access to private information is not the sole explanation of our results. These results are also consistent with the conventional view among sell-side analysts that while harder to obtain, management access remains important for analyst performance post-Reg FD. 4.2 Professional connections and analyst recommendations Loh and Mian (2006) examine the relation between earnings forecast accuracy and stock recommendations and document that superior forecast accuracy translates into more informative stock research. Brown et al. (2014) reveal that analysts’ top motivation for issuing accurate forecasts is to use these forecasts as inputs into their corresponding stock recommendations. Further, they suggest that communication with management is also an important input for stock recommendations. Following the existing literature (e.g. Loh and Stulz, 2011; Green et al., 2014a), we measure the informativeness of stock recommendations by the immediate market reactions to their release. We use abnormal 3-day CRSP value-weighted index-adjusted stock returns over the [0, 2]-day window around the announcement date of recommendation revision by analyst i for firm j at time t. Because of the asymmetric market reactions across upgrades and downgrades, we consider these separately. 7 We regress the market reaction on an indicator variable related to the presence of professional connections between the revising analyst and senior management in the coverage firm and also control for various firm, analyst and broker characteristics. Standard errors are heteroskedastic-consistent and double clustered at the analyst and firm level. Calendar year dummies are included to control for yearly fixed effects. Our model is as follows: CAR(0,2)i,j,t = β1 (Professional connection) + β2 (Size) + β3 (BM) + β4 (All-star) + β5 (GExp) + β6 (FExp) + β7 (Top10) + β8 (Past 6m Ret) + β9 (Rec Level) + β10(∆Recommendation) + β11 (Related experience) + β12 (Affiliated) + β13 (Education connection) + β14 (Optimism) + β15 (Local) + β16 (No of forecasts) + β17 (Drop coverage) +Year dummies + ε (2) In 2002, many brokerage houses changed their rating scales from a 5-point scale to a 3-point scale. For cases where a bank stopped coverage but then subsequently initiated coverage using a 3-point scale we use this scale going forward. To ensure this rescaling does not impact our results, we remove these revisions that were mechanically induced as a result of this rating change. 7 15 ***Insert Table 4 here*** Panel A of Table 4 presents results for upgrades. The first model indicates that professional connections lead to more informative stock recommendations. Market reactions are 0.35% higher for analysts possessing professional connections to executives in coverage firms. Models 2 and 3 include controls for alternative management access channels such as investment banking affiliation, educational ties, optimism and analyst locality. We confirm Cohen, Frazzini, and Malloy (2010)’s result that social connections to management through shared alumni networks leads to more informative upgrade recommendations. Optimism is discounted by market participants while analyst locality is not significant. Consistent with Stickel (1992) and others, all-star analysts generate higher market reactions as do upgrade revisions from analysts with higher general experience, industry experience, affiliated analysts and analysts at top 10 brokerage houses. The results are robust to the inclusion of analyst effort in model 4. 8 Models 5-12 focus on differences before and after the passage of Reg FD. The market reaction to analyst upgrade revisions with professional connections are stronger in the pre-Reg FD period, but remain economically and statistically important in the post-Reg FD period. For instance, model 5 indicates that professionally connected analysts generate 1.01% higher market reactions to upgrades in the pre-Reg FD period compared to 0.22% in the post-reg FD period (model 9). These results mirror the earnings forecast evidence. In Panel B for downgrade revisions, we do not find that analysts with professional connections lead to significantly more negative market returns. This is consistent with the notion that insiders may be less forthcoming about value relevant information on bad news to their analyst colleagues (Mayew and Venkatachalam, 2012). 9 4.3. Natural experiments of executive turnover We consider some other potentially omitted variables. Malloy (2005) suggests that analysts that focus in a single industry have better forecasts. Guan, Wong and Zhang (2014) illustrate that analysts following covered firm’s main customers outperform other analysts’ forecasts issued on supplier firms. Therefore, we include binary indicators for industry specialists and analysts following along the supply-chain to mitigate the potential concern that professional connections proxy for these effects. The results are robust in Table 5 and also in the earnings forecast performance specifications in Table 2. 9 As an additional way to assess the extent to which professional connections help analysts with their research outputs, we also examine target prices issued by professionally connected and unconnected analysts using a framework similar to Brav and Lehavy (2003). In untabulated analysis, we find that analysts with professional connections issue significantly more informative upward target price revisions (but not downward revisions) after controlling for the magnitude of target price revisions, as well as stock recommendations and earnings forecasts issued in conjunction with these price estimates. These results suggest that professional connections also help analysts issue more informative target price estimates. 8 16 It is plausible that unobservable analyst characteristics may drive our results on earnings forecasts and recommendations. To help address this issue, we examine changes in professional connections as a natural experiment. These are caused by connected senior managers in an analysts’ coverage portfolio switching firms. We identify 2,267 cases where a sell-side analyst loses her professional connection and 4,373 cases where she gains one. If the improved performance we find is indeed mainly driven by professional connections, we expect to see a decrease in relative forecast accuracy following the departure of connected insiders. Likewise, if losing connections caused by executives switching jobs reduces the information content of analysts’ stock recommendation revisions, we expect the market’s reaction to their upgrades to be muted. On the other hand, forecasting performance and information content of stock upgrades are expected to improve when a connected insider joins an existing followed firm. In this specification, Lose professional connection equals one if the forecast/recommendation is issued in the period following the departure of a professionally-connected insider, zero if issued in any of years prior to the connected executive leaving the firm. Gain professional connection likewise equals one if the forecast/recommendation is issued after the connected insider joins a firm lacking such connections, zero if issued before. 10 Therefore, we compare analysts’ research quality before and after executive employment switches holding the analyst constant. The models are similar to those in Table 2 and 4, but the connection variables are replaced with losing/gaining connections. 11 ***Insert Table 5 here*** Panel A of Table 5 documents that analysts’ relative forecast accuracy deteriorates by 4.77% following the departure of a professionally-connected insider in the coverage firm. Model 2 repeats the same analysis for analysts gaining a professional connection. Consistent with expectations, professionally-connected insiders joining the coverage firm positively impacts forecasting performance in the post-gain years. Accuracy improves by 4.53% when a professionally-connected insider joins the coverage firm. To further ensure that professionally-connected analysts do not already have a competitive advantage relative to other analysts before (for gaining) or after (for losing) employment switches, we The event year in which a connected insider leaves (joins) the firm is excluded from the sample since we cannot identify whether the change to an analyst’s professional connection takes place before or following the earnings forecast in the event year. Further, we require at least one earnings forecast before and after the gain/loss of a connected insider to capture the impact of changes in professional connections on analyst performance. 11 We exclude the variable Local because of lack of data. 10 17 compare the forecast accuracy of connected analysts impacted by the switch relative to other analysts following the same firms, however lacking connections. Model 3 of Panel A in Table 5 presents the results of analyst forecast accuracy in the period following the switch for analysts that lose their connection to management (Post-losing professional connection). The results suggest that analysts that lose their professional connection do not have significantly different forecast accuracy than other analysts. Model 4 provides a similar analysis for analysts that gain a connection (Pre-gaining professional connection). In the period before an analyst gains a connection, earnings forecast performance is not different from analysts that also do not have a professional connection. Panel B of Table 5 presents analogous analysis for stock upgrades. We find that when a connected analyst loses a professional link in the coverage firm, the market reaction is lower (0.49%) for upgrades compared to when the analyst had the link. Likewise, when an analyst gains a professional connection, the market reaction to upgrades is 0.42% higher in the period when the analyst has a connection relative to the period when no professional connections exist. Our results also document that analysts do not have competitive advantage in these firms relative to other unconnected analysts following the departure of their connected executives (model 3) or before such connected executives join these coverage firms (model 4). These results are similar to those reported for earnings forecast performance, underlining the importance of professional connections for the production of higher quality investment research. Coupled with the empirical evidence provided in Table 2 and 4, the results from this section point to a causal effect of professional ties on analysts’ forecast performance. By examining a natural experiment caused by executives’ employment switching, which disrupts professional ties to an analyst’s coverage portfolio, the evidence suggests that professional connections are important for analysts’ performance metrics. 5. Professional connections and all-star status Our evidence suggests that professional ties result in better accuracy and more informative upgrade stock recommendation revisions. As discussed previously, superior management access is among one of the most sought after qualities in analysts that buy-side institutions rank for the survey conducted by II magazine. In this section, we examine if professional connections lead to favorable career concerns. Actual compensation of analysts is very difficult to ascertain because of data constraints, but it is widely known that all-star status is a level of recognition that all analysts strive for and is widely adopted as a proxy for the level of compensation (Groysberg, Healy and Maber, 18 2011). Therefore, we test if analysts with professional connections are more likely to be named Institutional Investor all-star analysts. We estimate logistic regressions and control for a set of analyst characteristics that might be related to the probability of favorable career outcomes. These include general analyst experience (GExp), portfolio complexity (Portfolio size, Port sic2), brokerage size (Brokerage size), the mean annual forecast accuracy of analysts (Average PMAFE), average firm market capitalization in analysts’ portfolios (Average firm size) and pre-analyst industry work experience related to coverage firms (Analyst with related experience). Management access acquired through alternative channels are explicitly accounted for by the natural log of one plus social ties through alumni networks (Ln education connections), the number of stocks with optimistic views (Ln optimistic stocks), and the number of affiliated (Ln affiliated stocks) and local stocks (Ln local stocks) in an analyst’s portfolio in a given year. We also proxy for the level of analyst effort with average number of forecast revisions (Average no of forecasts) and stocks with no forecasts over the following fiscal year (Average drop coverage). Finally, because all-star status is likely subject to a high degree of autocorrelation, we also control for all-star status in year t-1 (All-star prior year). We control for year fixed effects and report heteroskedasticconsistent standard errors clustered by analyst. To mitigate concerns on reverse causality, in addition to All-star prior year, we lag all control variables by one year. Our variable of interest is the natural log of one plus the number of professionally connected stocks for a given analyst (Ln professionally connected stocks). Our formal model is as follows: (All-star = 1)i,t = β1 (Ln professionally connected stocks )t-1 + β2 (Average firm size) t-1 + β3 (GExp) t-1 + β4(Portfolio size) t-1 + β5 (Port sic2) t-1 +β6 (Brokerage size) t-1 + β7 (Average PMAFE) t-1 + β8 (Allstar prior year) + β9 (Analyst with related experience) t-1+β10 (Ln affiliated stocks) t-1 + β11 (Ln education connections) t-1 + β12 (Ln optimistic stocks) t-1+ β13 (Ln local stocks) t-1 + β14 (Average no of forecasts) t-1 + β15(Average drop coverage) t-1 + Year Dummies + ε (3) ***Insert Table 6 here*** Model 1 of Table 6 suggests that professional connections increase the likelihood of being selected an all-star analyst. Specifically, a one-standard deviation increase in the log number of professionally connected stocks increases the likelihood of becoming an all-star by 29%. To put this in perspective, the likelihood of becoming an all-star is 18% (14%) higher as the log number of optimistic stocks (general forecasting experience) is increased by one standard deviation. Consistent with Bradley, Gokkaya and Liu (2014), analysts with related pre-analyst industry experience are more likely to become all-star analysts. Other control variables are signed as expected. Earnings forecast 19 performance is related to being selected an all-star analyst, but professional connections are still important. This finding is consistent with buy-side investors’ claim that management access is an important factor that is incremental to earnings forecast quality when selecting all-star analysts. Decomposing the sample into pre- and post-Reg FD periods in model 5 through 12, our findings document the value of professional connections influencing the probability of star status remains important under the new regulatory regime. As an alternative way of examining the importance of professional connections to an analysts’ career, we consider career outcomes of analysts that work at brokerage firms involved in a merger. Typically, when brokerage houses merge, some analysts are let go to avoid duplication of effort. We estimate the probability of analyst i being retained by the newly merged firm using a logistic regression. In untabulated results, we find that the likelihood of being retained increases by 24.7% for a one standard deviation increase in the number of professional links to senior management in their coverage portfolios after the inclusion of the other control variables in equation 3. 6. Professional connections and impact on firms and brokerage commissions Our results to this point provide pervasive evidence that professional connections aid analysts’ performance and career outcomes. As an additional way to gauge the importance of analyst-executive connections, we explore its impact on some of the other players involved— coverage firms and brokerage houses employing connected analysts. Analyst coverage is beneficial to firms (e.g. Kelly and Ljundqvist, 2012), so our results can indirectly be interpreted such that professional connections provide value to firms in that they get coverage. However, it is not clear that professional connections drive the coverage decision. Thus, we test this conjecture. We next investigate the benefits accrued to brokerage houses from employing analysts with professional connections. If sell-side analysts provide superior corporate access to buy-side institutions through their professional connections, then we expect brokers employing such analysts benefit from this important client service through increased trading commission allocations. 6.1. Analyst Coverage Initiations We examine initiation decisions in the context of executive movements across firms in a similar spirit to Brochet, Miller and Srinivasan (2014). They find that analysts covering a firm that experiences a top-level executive departure are more likely to follow the executive to the destination 20 firm and conclude that this behavior demonstrates the importance of professional relationships developed between the analyst and executive for the firms. An important difference between our approach and theirs is that in our setting, we are able to pinpoint such professional relationships. We posit that analysts with professional connections to the executive should be more likely to initiate coverage on the executive’s new firm (relative to analysts lacking such connections) to maintain this relationship and competitive advantage. Note that this test has the added benefit that it is largely independent of performance measures. To test this conjecture, we consider a large sample of job changes (N=5,051) involving executives and board members and identify companies insiders leave (old firm) and firms they join (new firm). We estimate a logistic regression and include controls for structural barriers and perceived benefits related to coverage decisions across old and new firms. We consider the differences between old and new firms with respect to their primary industries (Same industry), size (Size diff (new-old)), book-to-market (BM diff (new-old)) and stock performance (Annual ret diff (new-old). We further consider the degree of analyst overlaps between these two firms (Analyst overlap), competition from other analysts (No of analysts (old), No of analysts (new)), and other analyst characteristic variables. Our primary variable of interest, Professional connection to migrated manager, is a binary indicator that takes the value of one if the analyst has a professional connection formed through common pre-analyst employment to the migrated manager, zero otherwise. The dependent variable (Migrated) equals one if the analyst covering the old firm initiates coverage on the executive’s new firm by the end of the first full fiscal year after the migrating executive joins the firm. Year fixed effects are included and standard errors are heteroskedastic-consistent that are clustered at the analyst level. Our model is as follows: (Migrated=1)i,t = β1 (Professional connection to migrated manager)t-1 + β2 (Same industry) t-1 + β3 (Analyst overlap) t-1 + β4(No of analysts (old firm)) t-1 + β5 (No of analysts (new firm)) t-1 +β6 (Size diff (new-old)) t-1 + β7 (BM diff (new-old)) t-1 + β8 (Annual ret diff (new-old)) + β9 (All-star)t-1+β10 (GExp) t-1 + β11 (FExp) t-1 + β12 (Affiliated) t-1+ β13 (Top 10) t-1 + β14 (Related experience) t-1 + β15(Education connection to migrated manager) t-1 + Year Dummies + ε (4) ***Insert Table 7 here*** Table 7 presents the results from the logistic regression. Model 1 suggests that analysts with professional connections to the departing executives are more likely to initiate coverage on their new firms. In economic terms, the odds of initiating coverage on the executive’s new firm is 2.1 times higher when analysts share professional connections with the executive compared to when no such 21 connections exist. Other controls are also signed consistent with expectations. For example, initiations of coverage are more likely when the new firm shares the same industry as the old firm. In models 2 and 3, we split the sample into pre and post-Reg FD periods and continue to find similar results. Taken as a whole, these results further our understanding of analyst coverage decisions and emphasize the binding nature of professional connections in financial markets. Also consistent with the evidence presented earlier, these new results highlight the importance of analyst-executive relationships even after the passage of Reg FD. 12 6.2 Brokerage commission allocations In a similar spirit to previous research (i.e. Irvine 2000; Goldstein et al. 2009), we measure relative firm-specific broker trading commission share as total commissions allocated to broker i on firm j by fund k during period t scaled by total broker commissions allocated for firm j by the same fund k at the same point in time across all brokers. Broker trading commissions are obtained over 1999 and 2011 period from Ancerno Ltd., a proprietary institutional transaction dataset. 13 We estimate OLS regressions of fund-firm level relative commission allocations across brokerage houses for transaction firms with sell-side analyst coverage. We control for a comprehensive set of broker and analyst characteristics that may also be related to buy-side funds’ trade allocations decisions. These controls include broker size (Top 10), analyst characteristics (i.e. GExp, FExp, Portfolio size, Port sic2, All-star), quality of earnings estimates (PMAFE) (Brown et al., 2014), related industry work experience (Related experience) (Gokkaya, Liu, Xie and Zhang, 2015) and analyst effort (no of forecasts, drop coverage). Potential analyst management access through alternative channels are controlled with investment banking affiliation (Affiliated), social connections via shared alumni links (Education connection), optimistic forecasting behavior (Optimism) and analyst locality (Local). Conrad, Johnson and Wahal (2001) suggest that buy-side institutions’ commission allocations across brokers display persistent behavior over time, and prior-period broker commission share is the most important determinant of current period broker allocations. Therefore, we control for one-year lagged firmlevel relative broker commission market share (% Lag Broker share). In unreported analyses we find that analysts sharing professional connections with migrated insiders continue to generate more informative earnings forecasts on these new firms relative to other analysts lacking professional connections. This suggests that the benefits obtained through professional connections are manager specific resulting in analysts maintaining their competitive advantages across different firms. On the other hand, migrating analysts lacking professional connections to the departing executive do not generate significantly more informative earnings forecasts in new firms. 13 Prior studies using Ancerno data include Goldstein et al. (2009); Chemmanur, He and Hu (2009); Puckett and Yan (2011), and Green et al., (2014b). 12 22 Our econometric model includes year fixed effects and report heteroskedasticity robust standard errors clustered at analyst and firm level. In addition to % Lag Broker share, we also lag all other control variables to mitigate reverse causality concerns. Our variable of interest is the binary indicator that equals one if analyst has professional connections to buy-side institutions’ transaction firm, zero otherwise. Our model is as follows: Broker share% i,j,t = β1 (Professional connection) t-1 + β2 (GExp) t-1 + β3 (FExp) t-1 + β4(Portfolio size) t-1 + β5(Port sic2) t-1 + β6 (All-star) t-1 + β7 (PMAFE) t-1 + β8 (Related experience) t-1 + β9(No of forecasts) t-1 + β10 (Drop coverage) t-1 + β11 (Education connection) t-1 + β12(Optimism) t-1 + β13 (Local) t-1 + β14(Top10) t-1 + β15 (Affiliated) t-1 + β16( % Lag Broker share) +Year dummies + ε (2) ***Insert Table 8 here*** Consistent with our conjecture, model 1 of Table 8 suggests that buy-side investors indeed allocate higher trading commissions to brokers on firms covered by sell-side analysts with professional connections. In economic terms, relative firm-level trading commission share of an average broker is 0.25% higher if the coverage analyst has privileged access to corporate management through professional connections. Other controls also have signs consistent with expectations. For instance, lagged commission share is the most important variable that factors into current year commission allocation decision. Our findings also reveal that analysts with all-star status, related industry work experience, higher firm specific forecasting experience and larger portfolio size are more influential in attracting broker trading commissions on their coverage stocks relative to analysts lacking such traits. Model 2 and 3 focus on a dynamic setting arising from executive employment changes. If gaining (losing) professional connections improves (mitigates) analysts’ ability to provide corporate access to their buy-side clients, we expect broker commission allocations to be increased (decreased) following such natural experiments. In line with our expectations, analysts losing professional connections experience 0.31% lower relative broker commissions on their coverage firms relative to when connections existed. Likewise, we find that commission allocations are 0.53% higher when an analyst gains a professionally connected executive in her coverage firm compared to the period when he lacked such a connection. Model 4 and 5 present the results of commission allocations in the period before (after) an analyst gains (loses) connections and document that analysts do not have any competitive advantage in attracting commissions in these period relative to their peers. Overall, the analysis from this section paints a very clear picture that sell-side analyst professional connections help employing brokerage houses attract higher trading commissions from investors. 23 7. Additional analyses and robustness tests In this section we provide some additional analyses and robustness tests. First, we investigate cross-sectional variation in professional connections for earnings forecasts, stock upgrades, and analyst career outcomes. Second, we consider alternative definitions of professional connections as well as forecast performance. Finally, we perform some robustness tests to mitigate concerns on omitted variables and provide an additional analysis on analyst boldness behavior. 7.1. Cross-sectional analysis in professional connections We first investigate whether professional connections exhibits cross-sectional variation with respect to the quality and types of connections to shed further light on our main findings. We first consider the directness of professional connections. The more direct the link, the stronger should be the information flow. We differentiate between primary (Primary professional connection) and secondary professional connections (Secondary professional connection) forged through employment networks and re-estimate equation 1, 2 and 3. ***Insert Table 9 here*** Table 9 presents these results. For brevity, only the coefficient estimates on primary variables of interest are presented; all other explanatory variables are suppressed. Model 1 shows that the relative accuracy of earnings forecast on coverage firms with primary professional connections are 4.9% more accurate compared to those of forecasts for firms where no such connections exists. Likewise, forecast errors are 2.1% more accurate for analysts with secondary connections with management. Models 4 and 7 replicate the analysis on upgrade stock recommendation revisions and the probability of becoming all-star analysts, respectively. The results mirror the evidence for earnings forecast performance. The differences in estimated coefficients between primary and secondary professional connections are statistically and economically significant in all cases presented in Table 9. Thus, we conclude that the more direct the link, the more valuable and precise the information flow is. Next, we consider the identity of professionally-connected executives to capture the quality of such connections. We distinguish between professional connections to CEOs/CFOs (Professional connection to CEO/CFO) and other insiders (Professional connection to non CEO/CFO). Top executives spend more time with analysts and they also have more insights on firms’ strategies and financial targets compared to other insiders. Therefore, we expect professional connections with 24 CEOs/CFOs to provide sell-side analysts superior information advantages. Splitting professional connections into CEO/CFO and other executives, we indeed find more profound benefits accrue to analysts with connections to these top executives. For instance, analysts professionally linked to CEOs/CFOs issue 5.54% (1.05%) more informative earnings forecasts (upward stock revisions) and are 87.4% more likely to become all-star analysts compared to their peers possessing professional connections only to other executives. Finally, we investigate the implications of professional connections to executives employed in customers and suppliers of coverage firms. Superior information obtained from insiders in the coverage firm’s customer-supply chain might provide professionally-connected analysts incremental information complementariness, resulting in more informative research (Groysberg and Healy, 2013; Guan, Wong and Zhang, 2014). In model 3 of Table 9, we partition professional connections to the coverage firm into two new explanatory variables based on the presence of professional connections also to the executives in the coverage firms’ supply chain (Professional connection- firm and CS, Professional connection- only firm) and re-estimate equation 1. 14 Consistent with our conjecture, the marginal impact of professional connection is higher when the same analyst also possesses professional connections to insiders in the customers-suppliers of the coverage firms. The results are also similar for stock recommendations and career outcomes as indicated in model 6 and 9. The results are also consistent pre- and post-Reg FD for each cross-sectional test in Table 9 (not reported). 7.2. Alternative professional connection measures and forecast performance A plausible concern with our analysis is that professional connections may proxy for superior forecasting by analysts on their former employers since professional ties are still likely to exist between the analyst and former employer. While the analysis on executive turnovers should alleviate this concern, for completeness we partition professional connections into two variables, Cover same firm and Professional connection (not-same-firm) that measures professional connections in the same firm and in firms other than the analysts’ former employers, respectively. Model 1 and 2 of Supplier-customer pairs are obtained from the Compustat Customer Segments database. For customer names that are abbreviated, we follow Cohen and Frazzini (2008) and manually match the customer name with the company name as indicated in CRSP. We eliminate firms where there is not a perfect match after inspecting the firm’s name, segment, and industry. 14 25 Table 10 provides these results for earnings forecast performance and stock upgrades, respectively. We find that both are economically and statistically important. ***Insert Table 10 here*** Another reasonable concern with our analysis is that we cannot precisely identify the location of overlapping employment. In other words, analysts and executives that we define as connected may have worked at different facilities and thus never communicated. However, if anything, this will increase noise and introduce bias against us finding anything. Nonetheless, to at least partially address this issue we relax the constraint that employment must be overlapping during the same time period. This, of course, would further lower the probability that the analyst and executive had a professional relationship. As a result, we would expect the results to weaken. By introducing more noise, this is exactly what we find. While the coefficient on professional connection remains negative and largely economically significant for forecast performance, they lose their statistical significance as shown in model 3. The same is true for stock upgrades in model 4 (positive coefficient, but insignificant). To make our results comparable to related work, we employ Clement’s (1999) commonly adopted measure of analyst relative earnings forecast performance throughout the paper. To ensure the results are also robust to alternative performance specifications, we follow Clement and Tse (2005) and Bae, Stulz and Tan (2008) and measure relative accuracy of earnings forecasts by a pricescaled range metric (Range). In particular, Range is defined as the ratio of the difference between the highest price-scaled analyst absolute forecast error for firm j in year t and forecasting analyst i’s price-scaled absolute forecast error for the same firm j in year t. This difference is then scaled by the range of price-scaled analyst absolute forecast errors for firm j for year t. We re-estimate equation 1 substituting this forecast performance measure in lieu of PMAFE for our dependent variable. Model 5 of Table 10 indicates that our results remain intact to this measure as well. 7.3. Additional analysis To control for unobservable time invariant analysts’ characteristics which could affect forecast accuracy, we next conduct an analysis with only a subsample of analysts making forecasts on both professionally-connected and non-connected firms and include analyst fixed effects. In other words, we compare the accuracy of forecasts issued by the same analysts on firms which she has professional connections relative to firms where no such connections exist. These findings are reported in Model 6 of Table 10. Forecasts of analysts are, on average, 4.1% more accurate when 26 professional connections exists to the coverage firm compared to other firms’ lacking such connections in the same analyst’s coverage portfolio, which is even greater in economic magnitude relative to the results in Table 2. Model 7 present a similar analysis on upgrades. Holding the analyst constant, we find that having professional connections to the coverage firm results in 0.65% larger abnormal market reactions to upgrade revisions. These point estimates are also larger in economic magnitude than those presented in Panel A of Table 4. As a final test, we consider if analysts that are connected are more likely to provide bold forecasts that go against the consensus. The literature suggests that bold forecasts reflect superior analyst information on the coverage firms (Hong, Kubik and Solomon, 2000; Clement and Tse, 2005). It follows that analysts with connections are more likely to deviate from the herd if they receive value-added insights from their superior management access. To test this conjecture, we estimate a logistic regression model where the dependent variable takes a value of one if a bold forecast is released, zero otherwise. Model 8 presents these results. Consistent with our expectations, analysts with professional connections are more likely to issue bold forecasts. 8. Conclusion Access to management is deemed one of the most important sources of information by sellside analysts and also buy-side institutions that rank the top analysts in their industry. This begs an important question—how does one get access to management? In this paper, we consider one such unique channel formed through overlapping employments. We tie the pre-analyst employment backgrounds of financial analysts with the senior management of firms in which these analysts cover creating professional connections. We conjecture that these professional connections should be related to analysts’ performance and coverage decisions by giving connected analysts a competitive advantage in acquiring and/or interpreting information. Using a large panel of employment-connection links and analysts’ earnings forecasts between 1993 and 2011, we find the relative accuracy of earnings forecasts issued on professionally connected firms is better than forecasts on firms lacking such connections. Professional connections also translate into more informative stock recommendations. These results are robust to controlling for other analyst characteristics, analyst effort and also alternative channels of management access. Regulation FD has diminished, but not eliminated the information advantage provided by professional connections suggesting that preferential access to private information is not solely 27 driving our results. This provides additional support for the continued emphasis on management access by sell-side analysts and buy-side institutions in the post-Reg era. Perhaps most importantly, when we consider natural experiments to exploit changes in professional connections caused by executives’ job movements, we find that accuracy improves (worsens) when a professional connection is gained (lost). Likewise, market reactions to upgrades are lower (higher) when a connection is lost (gained) as a result of an executive switch. Similarly, connected analysts affected by executive job movements do not have better performance relative to their peers before (after) connected executive movements (departures), further emphasizing that analysts possess a comparative advantage through professional connections. In addition, we find that having professional connections to coverage firms increases the likelihood of being selected to Institutional Investor’s all-star team. Focusing on executive job changes, we also examine the impact of professional connections on coverage initiation decisions. Analysts with professional connections to executives that move firms are more likely to initiate coverage on the executive’s new firm. Finally, our results illustrate that buy-side investors reward brokerage houses employing analysts with professional connections to their transaction firms through greater allocation of trading commissions. Overall, our paper provides pervasive evidence that access to management via professional connections is a unique and economically important information channel that aids sell-side analysts in providing more informative research, leads to more favorable career outcomes and is related to their coverage decisions. Professional connections also factor into buy-side investors’ commission allocation decisions across brokerage houses. 28 References Asquith, P., Mikhail, M., and Au A., 2005, Information content of equity analyst reports.
