It is a typical real asset due to the physical form and fixed geographic location with a steady return. However, real estate has its limitations. Risks associated with it such as lack of trading flexibility, special property management expertise required, and a growth prospect not always applicable towards the short term favor have impeded certain institutional investors from allocating major investment in real estate. In management of a dynamic investment portfolio, how institutional investors look at certain real assets is the key issue discussed in this thesis. Infrastructure, for instance, which can refer to roll roads, shipping or railways, is a comparable asset with real estate as it demonstrates a term with physical form and stable income stream. There are other types of real assets such as commodity, regulated utilities, and maritime assets which are also studied. This thesis delves into the dynamic structure of an institutional investment portfolio and targets to explore the following questions: What do real assets contribute to institutional investors’ traditional stock-andbond portfolio? What kinds of correlations do real assets have with typical equity and fix-income assets? How do institutional investors strategize their investment plan by allocating real assets in their global portfolio? The thesis is designed to study the underlying factors for determining the asset allocation framework from both a qualitative and a quantitative perspective. A quantitative analysis including mean-variance optimization, downside risk, correlations, risk parity and Value at Risk will test out how various asset allocation frameworks position real assets in a portfolio. The study also brings in selected real estate indexes to examine how different parings compare with each other and what impact does illiquidity exhibits on portfolio management. An interview-based research is designed to provide understanding of institutional investors’ perspective on how they apply the theoretical framework to the real world practice and how they strategize the management of investment portfolios.

The ffollowing diaagram shows tthe typical alllocation framework for insstitutional inv vestors.1 Figure 1-In nstitutional Plaan Sponsor Assset Allocation Framework F Allocation by Percen ntage Other O 4% Real Estate E Cash 10% 1% Hedge Funds F 7% % Private Equity E 8% 8 Bond 26% Stocks 44% 0% 10% 20% 30% Alloocation Percenttage 40% 50% Source: 2012 2 Institutionaal Real Estate Inv vestor Survey Traditionaally, institutio onal investorss have allocateed around 10 % to real estaate.

It also tracees back to paast industry publications an nd academic researches r whhich focus onn asset allocattion and portffolio managem ment. Chapter 3 goes into th he detailed po ortfolio analyssis.

They aare generally hheld to protect investors from inflation. Some S argue th hat “real assetts ought to bee valuable forr portfolio diversificaation becausee widely diverrsified portfollios of stocks and bonds arre strongly neegatively correlated d with inflatio on. Thus real assets a are imp portant partlyy because theyy might provide a kind of inflation insurance i for other assets in i the portfoliio.”3 ut not all real estate types aare. In a 2011 PREA Quartterly article, Real estatte is a type off real asset, bu panels4 sp pecifically disscussed the caategory of reaal assets and sstated that corre real estate bbelongs to reaal asset, but opportunisticc properties su uch as distresssed commerccial propertiess don’t providde a long stannding e to their holders. Rath her, these prop perties don’t uusually have a correlation to the normaal hedging effect investmen nt portfolios. They providee high alpha liiquidity if invvested as oppoortunistic assets, but not beta contributiion. Thereforee, real estate here h refers to core real estaate with incom me generatingg function. Harvard Business B Scho ool professor Kenneth A.

Investors’ unnderstanding of a real assett can be diffeerent. So what assets Here the term t “real” haas two distincct financial meanings: real return after aadjusting for iinflation; reall asset that is tan ngible with inttrinsic value. 5 We can see that physicallly tangible asssets such as railroads, tolll roads, and d real estate properties p can be real assetss. Commodityy, including aagricultural prroducts such as corn, sugaar, rice, and bean b can also be real assetss. The futures commodity m market has geenerally been volatile accross time.

A Froot, “Hedging Portfolios wiith Real Assets-w which real assetss can help protecct financial portffolios?” 1995 Zia Mohiu uddin Ansari, “Porfolio Risk Maanagement in Shiipping Real Asseets and Shippingg Security Assetts”, Erasmus University Rotterdam, R 2006 6 9 17 In 2007, Alternative Investment Analytics studied the role of commodities in an institutional portfolio as a real asset by examining the optimal asset allocation for a target return to several selected real assets including TIPS, NCREIF, Bond, and Equity. The research found out that “real assets may contribute substantially to traditional stock and bond portfolios.” And that “certain real assets, such as the BCI commodity index may serve as a hedge against inflation risk.” 10 In a 2011 research by Mellon Capital Research, real asset is defined as those that “retain purchasing power when paper currencies lose buying power. That is, real assets increase in nominal price at least as fast as inflation.” The author concluded from the research that the real assets including physical real estate, land, physical commodities, and TIPS have hedging and diversification roles in stock and bond heavy portfolios but managing diversified physical real estate and land requires operational skill, which leads to a liquidity concern in this thesis research that intends to take into account. 11 In a 2011 academic research by Technische Univsersitat Munchen, Rothballer and Kaserer studied the infrastructure’s role in risk management and found out that infrastructure stocks on average exhibit significantly lower market risk than other equities while there is large variation among different infrastructure classes. The study concluded that infrastructure can be characterized as an ‘average volatility, low beta’ business, implying that infrastructure firms have a similar level and an even higher share of idiosyncratic risk compared with other equities. 12 In a 2012 research paper published by J.P. Morgan Asset Management, Joseph, Dessner, and Santiago, together with the research team, explored the inflation issue in asset allocation strategy by examining historic performance of different assets with respect to their effectiveness against inflation. The paper also looked at the active and passive strategies in managing inflation risks to study what is a practical way to react to inflation change in both downturn and growth periods. 13 More recently in April 2012, J.P. Morgan published a research on asset allocation framework for global real assets that includes real estate, infrastructure, natural resources and transport.

The research explores the resurgent demand for alternative investments by examining the alternatives allocation in the global institutional market. The study also predicts that asset managers are expected to increase their alternative-like products by 5 percentage points in the next several years.15 14 Joseph K. Azelby, Michael C.

Infrastrructure has slightly higher mean than sttock with a coomparable rissk as stock. Commodiity, in generall, has a high volatility. v Oil price, as a suubcategory off commodity, has an even higher vollatility than commodity beecause of its risk r associatedd with global market uncerrtainty. 21 Figure 6-Scatter Plot of Returns and Risks among Selected Assets Scatter Plot Of Returns And Risks Among Selected Assets 16% 14% Composite Infra SP500Stk WTI Oil Annual Return 12% NCREIF NPI 10% USTBnd 10-yr 8% SP GSCI 6% Inflation 4% 2% 0% 0 0.1 0.2 0.3 0.4 0.5 Risk Source: Global Financial Data, NCREIF, U.S. Bureau of Labor Statistics Correlation Analysis First, we compare stock and bond with commodity, infrastructure and real estate for the period from 1975 to 2009 to include complete economic cycles.18 Correlation for 1975-2009 S&P 500 Stock US 10-year Treasury Bond S&P GSCI Composite Infra NCREIF NPI 0.10 0.76 0.14 -0.18 0.24 -0.05 Both real estate and commodity have low correlation with stock. Infrastructure has a high correlation with stock. Both real estate and commodity have negative correlations with long term Treasury bond. Infrastructure also has a higher correlation with stock than real estate and commodity do. Then we add in the data from 2010 to 2011 to see how the past two years affected the correlation. Correlation for 1975-2011 18 The selection of time frame is based on the decision to include both the periodic peak and bottom points in the history of stock, bond, commodity, infrastructure and real estate. 22 S&P 500 Stock US 10-year Treasury Bond S&P GSCI Composite Infra NCREIF NPI 0.11 0.75 0.13 -0.19 0.24 -0.04 The extension of data presents similar results. Both real estate and commodity have low correlation with stock and negative correlations with long term Treasury bond. Infrastructure maintains a high correlation with stock and bond. Then we take out the data from 2008 to 2011 to look at the historic movement from 1975 to 2007.

Commodity goes negatively correlated to stock. NCREIF NPI moves even further less correlated to stock from 1975 to 2007 than from 1975 to 2009/2011, and goes much more negatively correlated to Treasury bond. The impact of financial crisis helps bring real estate and commodity down together with stock.

From the correlation matrix for 1975-2011, commodity has a correlation of 0.11 with US stock. However, if we take out the data during financial crisis from 2008 to 2009, we get a correlation of -0.14 between S&P 500 and S&P GSCI. This result indicates that historically, commodity is negatively correlated with US stock market. But with the financial crisis, both the stock market and commodity price moved down significantly and in the past two years, both asset classes move together. 24 REAL ESTATE VS STOCK Figure 9-S&P 500 and NCREIF NPI Historic Index (1975-2011) S&P 500 and NCREIF NPI Historic Index (1975-2011) Total Index 1974=100 7,000 6,000 5,000 4,000 3,000 2,000 1,000 0 Year SP500Stk NCREIF NPI Source: Global Financial Data Figure 9 shows how stock index moves compared with real estate.

From the correlation matrix for 1975-2011, real estate has a correlation of 0.13 with US stock. If we take out the data during financial crisis from 2008 to 2011, we get a correlation of 0.06 between S&P 500 and real estate. This result indicates that historically, real estate has low correlation with US stock market. But with the financial crisis, both the stock market and real estate moved down in somewhat close ties in the past two years. Different from the movement of commodity, real estate exhibits some kind of lag. INFRASTRUCTURE VS STOCK Figure 11-S&P 500 and Composite Infrastructure Historic Index (1975-2011) Total Index 1974=100 S&P 500 and Composite Infrastructure Historic Index (1975-2011) 9,000 8,000 7,000 6,000 5,000 4,000 3,000 2,000 1,000 0 Year SP500Stk Composite Infra Source: Global Financial Data Figure 11 shows how infrastructure moves compared with stock.

From the correlation matrix for 1975-2011, infrastructure has a correlation of 0.75 with US stock. If we take out the data during financial crisis from 2008 to 2011, we get a correlation of 0.72 between S&P 500 and infrastructure. This indicates that even with the financial crisis starting in 2008, both transportation and stock move very closely. Therefore, infrastructure is highly correlated with the US stock market regardless of the financial crisis impact. COMMODITY, REAL ESTATE AND INFRASTRUCTURE VS INFLATION Then, we examine how several real assets react to CPI in order to understand their hedging role against inflation. 19 Correlation for 1975-2011 Inflation S&P GSCI Composite Infra NCREIF NPI 19 -0.01 0.22 0.40 NCREIF data started from 1978 27 Correlation for 1975-2009 Inflation S&P GSCI Composite Infra NCREIF NPI -0.02 0.22 0.42 Correlation for 1975-2007 Inflation S&P GSCI Composite Infra NCREIF NPI -0.03 0.25 0.36 Co-movement: From the correlation matrix for 1975-2007, 1975-2009, 1975-2011, commodity has a negative correlation of between -0.03 and -0.01 with US Inflation. Infrastructure and real estate both have a relatively high correlation between 0.22 and 0.42, which indicates that infrastructure and real estate may be good hedges against inflation. Figure 13-Annual Returns of Selected Assets VS Inflation Movement Annual Returns (1975-2011) 15.00% Annual Return 40% 10.00% 20% 5.00% 0% 0.00% -20% -5.00% -40% -10.00% -60% -15.00% Year SP GSCI NCREIF NPI Composite Infra Inflation Source: Global Financial Data, NCREIF, U.S. Bureau of Labor Statistics 28 Annual Inflation 60% Figure 13 show the annual return of commodity, infrastructure and real estate compared with inflation adjusted for scale of movement. Commodity has been consistently volatile throughout the period. Infrastructure appears less volatile than commodity, but still higher than real estate. OIL VS INFLATION, STOCK AND COMMODITY What about oil’s correlation with stock and inflation? We construct the same correlation analysis, below is the result. Correlation for 1975-2011 SP500Stk SP GSCI Inflation WTI Oil 0.09 0.62 0.07 Correlation for 1975-2009 SP500Stk SP GSCI Inflation WTI Oil 0.09 0.62 0.07 Correlation for 1975-2007 SP500Stk SP GSCI Inflation WTI Oil -0.13 0.61 0.19 From the correlation matrix for 1975-2007, oil has a correlation of -0.13 with US stock. From the correlation matrix for 1975-2009, oil has a correlation of 0.09 with US stock. From the correlation matrix for 1975-2011, oil has a correlation of 0.09 with US stock. Oil price was impacted by the financial crisis and moved somewhat closer with the stock market, although not enough to indicate any strong co-movement with stock. From the correlation matrix for 1975-2007, 1975-2009, 1975-2011, oil always has a high correlation with commodity, which indicates that oil, as a type of commodity, exhibits similar characteristic to general commodity in terms of annual index fluctuation. 29 Interestingly, oil price has relatively lower correlation with inflation than do real estate and infrastructure, indicating that oil may not be as good an inflation hedge as real estate and infrastructure. 20 REAL ESTATE, FARMLAND, TIMBERLAND VS STOCK Then, we take the three sub asset classes within real estate to look at the performance of each individual asset with stock. Quarterly return is used in place of annual return for the period between 1992 and 2012. The correlation matrix is as below: 1Q1992-1Q2012 NCREIF NPI 0.19 SP500Stk NCREIF Farmland 0.11 NCREIF Timberland 0.02 Figure 14-Scatter Plot of Returns and Risks among Selected Assets (1989-2011) Scatter Plot Of Returns And Risks Among Selected Assets (1989-2011) 3.00% NCREIF Farmland 2.50% NCREIF Timberland NCREIF NPI USTBnd 10-yr Return 2.00% SP500Stk 1.50% 1.00% 0.50% 0.00% 0 0.02 0.04 0.06 0.08 0.1 Risk Source: Global Financial Data, NCREIF Risk-return analysis (return is expressed as quarterly return) Mean Risk 20 SP500Stk USTBnd 10-yr NCREIF NPI NCREIF Farmland NCREIF Timberland 2.37% 8.35% 1.79% 4.38% 2.00% 2.45% 2.77% 3.26% 2.51% 3.93% Kenneth A. Froot, Hedging Portfolios with Real Assets-which real assets can help protect financial portfolios? 1995 30 From the Mean-variance graph, we can see that traditional real estate index (NCREIF NPI) has lower average quarterly return than stock, and slightly higher average quarterly return than Treasury bond. The quarterly risk is less than half of stock for real estate NPI. Both farmland and timberland have higher returns than stock and less than half the risk of stock. Stock market is much more volatile in terms of quarterly performance than the three real estate indices. Among the three real estate categories, farmland and timberland have shown attractive return-variance prospect.

Farmland was not as driven down as timberland during the financial crisis. Farmland has been surging throughout the data period. However, no indication of industry background was given at this stage of the thesis. 31 Figure 16-Quarterly Returns (1992-2011) Quarterly Returns (1992-2011) 30% 25% Quarterly Return 20% 15% 10% 5% 0% -5% -10% -15% -20% -25% SP500Stk NCREIF NPI NCREIF Farmland NCREIF Timberland Source: Global Financial Data, NCREIF If the numbers hold and we assume this 20-year period data somehow represents the market in general, then by including real estate, especially farmland and timberland in a stock and bond portfolio will largely reduce the portfolio risk. Farmland and timberland also offer competitive return prospect. However, the data is only based on a period spanning 20 years, which may not cover an economic cycle that is of appropriate scale to ensure the application of the result. Conclusion The correlation analysis among different assets provides some interesting results to look at the diversification and hedging potential of different assets. Both commodity and real estate have low or negative correlations with stock, but both were hit by the financial crisis in 2008, which increases their correlation with stock. Infrastructure, on the other hand, has a very high correlation with stock and moves alongside the stock during the financial crisis. Both infrastructure and real estate have a notable correlation with inflation, indicating that these assets can be held to at least partly hedge against inflation. Commodity, however, has a negative correlation with inflation, which is interesting to note. Oil price has little correlation with stock and inflation, and has a high correlation with commodity. As oil is also a type of commodity, it somehow exhibits a similar character as commodity index. 32 Farmland and Timberland in the NCREIF index, interestingly, show a similar character to NCREIF NPI except that the effect of financial crisis has limitation on these two assets. Both of these two assets have comparable returns as stock, but less volatile than stock. They have great potential for those investors who seek high return and comparable risk level as real estate. The data history for farmland and timberland is relatively short, which may not cover the full spectrum of the market. 33 Chapter 4 4.1 Portfo olio Analysis Litterature Reviiew P Theo ory was devellopment in thee 1950s throuugh 1970s.

This enables commodity to take at least some weights in the portfolio. But so does real estate. We look at the composition of all five assets in Figure 20, and we can see that real estate overshadows commodity in the optimum portfolio composition from the start. Why? From the correlation matrix, real estate has a similar correlation with stock and bond as commodity does, the average mean is also similar to commodity, but has a much lower volatility than commodity does. Therefore, to minimize the portfolio variance with a target mean, real estate overtakes commodity in that with the same contribution to mean, real estate has a lower volatility to contribute to the portfolio. With the inclusion of infrastructure, the high return and similar volatility as stock provides a very plausible alternative in an investment portfolio. PureProperty At last, we include PureProperty index in the overall portfolio analysis. Since PureProperty has only around 10 years of data, the author compares it with REITs index as PureProperty is the stock market's valuation of the REITs' properties as indicated by REIT equity share prices.

By including PureProperty in the overall portfolio, it reduces the overall variance while maintaining a healthy return target. That explains why PureProperty dominates the composition chart throughout. However, because our assumption is based on the high correlation between PureProperty and REITs with limited data history (10 years versus the 34 years the model uses), there is limitation in how much the result can be applicable. As PureProperty eliminates the leverage effect that REITs usually depend on, the returns on PureProperty appears different than those on REITs. However, REITs returns are still higher than NCREIF NPI index. The financial crisis forced REITs to recapitalize at the downturn of the market as REITs had to issue more diluting stock shares to repay the debt they owe before the financial crisis. This repayment did not affect as much on the properties assets as the REITs themselves, but they did hurt the return on equity.26 Downside Risk In this analysis, downside risk calculation is as follows 27 Semi-deviation defined by 1 ( )=( ( − [ ]) 1 = 1 ≤ [ ] 0 [ ] Where 1 [ ] [ ] ) is an indicator function, i.e. Below target semi-deviation for target t defined by ( , )=( ( − ) 1 ) Downside correlations are calculated as: 26 27 David Geltner, Professor of Real Estate Finance, Center for Real Estate, MIT, 2012 Definition from Wikipedia 42 Corr (A, B) downside , where A represents the series of difference between annual return that is below overall average return and the average return, while where annual return is above average return, this difference is expressed as zero. The same rule applies to asset B. First, we run the efficient frontier and market portfolio for downside risk. Below is the result for portfolio compositions at different mean targets with standard risk on the left and downside risk on the right: Figure 24- Downside Markowitz Portfolio Comparison MEAN-VARIANCE SPACE E[r] 12% 7% 0% 5% S+B+R 10% VOLATILITY S+B+C+I 15% 20% S+B+C+I+R Source:Global Financial Data, NCREIF On the downside, the portfolio including commodity and infrastructure perform slightly better than the one including real estate. The inclusion of real estate on top of commodity and infrastructure does not change much of the Markowitz portfolio volatility.

When investment managers set up relatively high target returns, infrastructure’s role in a mixed portfolio improves. Commodity, interestingly, has little weight in all the portfolio compositions and all the downside risk portfolio compositions. This is mainly due to the high volatility of commodity and relatively low average return. However, the high volatility of commodity also attracts hedge funds and high-frequency traders who are more risk tolerant than traditional institutional investors who are more long-term players. Real Asset Roles Both infrastructure and real estate have major roles in the efficient frontier. It depends on the investor’s risk aversion and specialty to decide on the portfolio structure. Real estate index dominates infrastructure in the Sharpe-Markowitz portfolio. Within real estate, PureProperty is slightly more dominant than private real estate in that it offers similar risk and higher return, which explains the high weights in the Sharpe-Markowitz portfolio in the standard, downside risk model, and the ones with haircuts regarding liquidity. When PureProperty and NPI are put together in a portfolio of assets, both of them have notable weights. Commodity has little weight in the efficient frontiers in both standard and downside risk models. The high volatility of commodity attracts short-term investors, but may not take a major role in the longterm investor’s portfolio. 45 Chapter 5 5.1 Value at Risk Ana alysis Deffinition V at Risk?? What is Value It is a meaasure of poten ntial loss of a specific valu ue on a defineed time periodd and a given confidence interval. VaR V focuses on o the potentiial losses for investors i to eestimate the pprobability of a certain percentilee confidence level. l For exaample, a 1 milllion VaR at 55% at one dayy level meanss there is a 5% % chance thaat there is mo ore than 1 milllion of loss an nd there is a 995% chance tthere will be 1 million gainn in any one day. d o a typical Value-at-Risk V are: Thereforee, the factors of 1.

Then we have: 29 Here the author uses FTSE NAREIT Equity REIT index to represent PureProperty with haircut modification as noted in the preceding paragraphs. 30 Historic index for healthcare only started in 1987. The thesis creates an average of S&P 500 Railroad and S&P 500 Utility represent the index from 1975-1986, average of all three indexes total return to represent the composite index from 1987-2009. 47 = ∗ ( ) Now we run another efficient frontier analysis and market portfolio with some haircuts to each asset to net out the transaction cost effect. 31 Below are the market portfolio weights SP500Stk 9% USTBnd 10-yr 27% SP GSCI 3% Composite Infrastructure 0% PureProp 37% NCREIF NPI 24% In order to create a random history of the aggregate market value, we introduce the following variables: 1. Risk-free interest rate The assumption is that the portfolio value will increase at a fixed annual interest rate at 3%. 2. Market risk premium The assumption that the market value increases at a fixed risk premium rate on top of the risk-free interest rate at 6%. 3. Random volatility This is a normal (Gaussian) distribution. By introducing this random variable, we add in the possibility of increasing or decreasing at a random percentage (between 0% and 100%) of the assigned volatility of 15%. Volatility is realized in each period, so that this risk outcome accumulates in the history of market value levels. 4. Auto Regression We also introduce an Auto Regression factor at 0.2 upon previous year’s return to reflect the lagging effect. This in turn, will also affect the annual volatility. 5. Circles We introduce another deterministic factor as circles of 10 years to reflect the circular effect of asset performance. 6. Black-swan effect 31 This composition is slightly different from the Sharpe-Markowitz weights derived from the previous chapter as certain haircuts are applied to each asset to net out the transaction cost. 100 bps for real estate, 50 bps for PureProperty, 20 bps for stock, bond, infrastructure, and commodity. 48 Lastly, L a Black k-swan effect is added to factor fa in the faat-tail of certaain asset perfoormance. Thiis is allso a random generation fo or the assigned period for tthe purpose of simulation. Then we run r a 50-year simulation of the single assset factoringg in the differeent combinatiions of the abbove variables. The starting value of the asset a is fixed at 1 $. Below w is the result..

There arre six assets too composite tthe Now we factor portfolio. First, we takee a look at thee individual asset’s a perform mance using tthe Monte Caarlo simulatioon. 49 Below is a list of factors we take into account: Differential Trend Idiosyncratic Volatility Beta with Market AR Parameter S&P 500 LTBond Composite Infra Commodity PureProperty NPI 1.51% -2.79% -2.30% 2.19% -1.18% -2.61% 10.00% 1.25 0.30 5.00% 0.54 0.00 15.00% 0.62 0.20 10.00% 1.37 0.20 10.00% 0.80 0.20 10.00% 0.56 0.20 Differential Trend is a deterministic trend component apart from the "Market" trend determined on the preceding sheet. Normally in equilibrium per the CAPM this would equal the Beta of the asset class with respect to the market minus 1. We make the assumption of the idiosyncratic volatility for stock, commodity, PureProperty and NCREIF NPI 10%, infrastructure’s idiosyncratic volatility at 15% and T-bond’s idiosyncratic volatility at 5%. Market beta of each asset is calculated as = [ ] [ − ]− We also assign the Auto Regression factor of 0.3 to stock, 0 to T-bond, and 0.2 to infrastructure, commodity, PureProperty and NPI. This will inject auto regression into the asset class returns. The auto regression will induce a lag or smoothing in the asset class. Then, we create a Monte Carlo simulation of 50 years’ price index for each asset and the market. The indexes all start at 1. 50 Figure 27-One Random History ("Drawing") of the Asset Classes' Histories One Random History ("Drawing") of the Asset Classes' Histories Asset Classes Value Levesl / Init $ Value 1,000 100 10 1 0 0 5 10 Riskless Asset Commodity 15 20 S&P 500 Mkt 25 30 Years LTBond PP2 35 40 45 50 Infra NPI The 50-year simulation shows that since we factor in the market beta using CAPM, there is certain degree of co-movement with the market. The individual assets also somehow drift away from the riskless asset. Economic cycles are factored in to reflect the ups and downs of certain period within an assumed cycle.

Figure 38-IIndividual REIITs indexes vs Composite RE EIT index Source: FTSE E, MIT CRE 61 The graph shows the movement of all individual REITs indexes within the 10-year period. Certain REITs have outperformed other REITs because of the idiosyncratic nature of these specific REITs. But we can see that the REITs market started to slow down starting in late 2006 and took a bigger hit from the financial crisis in 2008. Some REITs recovered faster than others, and the majority of the REITs have been recovering more mildly. After the financial crisis, there are several REITs which diverged further away, causing a “black swan event” with a “fat tail”, adding additional noise to the REITs index. Then, we look at the REITs index from two risk perspective: 1. The volatilities of the composite REIT index 2. The idiosyncratic risks of individual REITs away from the composite index Here as the second risk is the idiosyncratic risk away from the composite index volatility, we assume that the volatilities of the composite REITs are independent of the idiosyncratic risk away from the composite index. The relationship is expressed as below: ( + ) = ( ) + ( ) ( , ) = 0 If X and Y are uncorrelated, that is In other words, let’s use , to represent the return of REIT i at time t, and , to represent the excess return of this REIT i at time t on top of the composite index return expressed as , , then the correlation of the average return and the excess return at time t is zero. , And , =0 , = , , + , Then, Here = , , , + ( , ) denotes the average variance of all individual REITs, of the composite REIT index, and ( , , denotes the variance ) denotes the variance of the excess returns of all individual REITs.

Monthly volatility of the composite REIT index is 7.19%. Average monthly volatility of all individual REITs is 9.99%. Annual volatility of the composite REIT index is denoted as: = √12 ∗ Therefore, annual volatility of the composite index is And annual variance of the composite index is Annual volatility of individual REITs is = , = 6.2% , = √12 ∗ 9.99% = 34.6% , ( And annual variance of the individual REITs is = √12 ∗ 7.19% = 24.9%, , , )= , = 12.0% According to the variance equation We get , = , + , = ( , − , ) , = 12.0% − 6.2% = 5.8% = Therefore, annualized idiosyncratic volatility is 64 , = 24.1% Monthly idiosyncratic volatility is = √ = . % √ = 6.9% What does this imply? The drift of individual REITs away from the composite index has an annual volatility of 24.1%, or a monthly volatility of 6.9%, no matter how the composite index moves. The idea of rebalancing is to recalculate each individual REIT’s new weight from regression for trading, and these new weights are new levels of indexes for individual REITs which need to either sell or buy to rebalance to these new levels. The following part will delve into the rebalancing process to reexamine the risk analysis in this part. Then we switch from standard deviation (volatility) to average absolute deviation by multiplying approximately 0.8 times the standard deviation. = ∗ 0.8=6.9%*0.8=5.52% This is the average absolute monthly drift for the average REIT index. Monthly Turnover Analysis PureProperty index has a review process for weights of all individual REITs each month. Below is the basic process of rebalancing according to FTSE: 1. Monthly review For the total of more than one hundred individual REITs, FTSE reports daily weights based on trading. Every month the new weights are applied to each individual REIT of the PureProperty Index Series. 2. Rebalance once a month The weights for individual REITs are recalculated on the second Friday of each month following the algorithm regression models using data available as of the close of business on the previous day. 3. Weights change Weight changes resulting from the monthly review will be implemented at the close of business on the third Friday of each month. To illustrate the data: 65 The author uses PureProperty price index and weights. Here we use data of 109 individual REITs’ oneday prices and weights. The data is April, 2nd to represent a typical rebalancing day.37 The following graph demonstrates one individual REIT’s rebalance movement. Figure 42-Illustrative Rebalancing Graph This diagram is a demonstration of daily weight movement compared to target monthly weight movement. As weights drift away from target level, the weights will be readjusted to the target level each month, causing either short or long position. For all REITs included in the FTSE NAREIT PureProperty index, there are 109 (the total number of listed REITs) such pairs of weight movement lines throughout time. The weights are percentage numbers. Then, we sum up all the absolute differences in weights to get daily turnover percentage of individual constituents. Results: The following table shows the turnover of all 22 constituents on a typical day of April 2nd, 2012. 38 37 According to FTSE, rebalancing happens every month on the second Friday according to FTSE, trading happens after the third Friday every month. 38 Here we use single-day data to represent a typical day of rebalancing. 66 Figure 43-Sample Turnover Summery of 22 Constituents of REITs Row Labels FNPAPD FNPERAPD FNPEROPD FNPERPD FNPERRPD FNPHCPD FNPHPD FNPIPD FNPMRAPD FNPMROPD FNPMRPD FNPMRRPD FNPOPD FNPRPD FNPSRAPD FNPSROPD FNPSRPD FNPSRRPD FNPWRAPD FNPWROPD FNPWRPD FNPWRRPD Grand Total Sum of Turnover 0.010285235 0.061947647 0.059565884 0.056272018 0.07829051 0.017652481 0.021422112 0.025784902 0.204960462 0.48375106 0.177340221 0.27260383 0.0209419 0.020292819 0.045233486 0.187553978 0.126305879 0.39230771 0.02713054 0.074567894 0.056507023 0.149526836 2.570244426 The average turnover rate of all constituents is 11.68%. As rebalancing happens once a month, we multiply the monthly turnover rate by 12 to get the annual turnover rate, 140%. Now let’s look back at the idiosyncratic drift from the previous analysis. The average monthly absolute deviation is about 0.8 times the standard deviation. = ∗ 0.8=6.9%*0.8=5.52%. For simplicity, we use 6% here. The average normal weight of trading individual REITs is 2.4% across all 22 constituents based on the analysis of the data of April 2nd 2012 and the average normal weight of trading individual REITs for all eight tradable REITs is 1.75%.39 Therefore, we apply the “tradable” rate to the all 109 individual REITs with the monthly drift rate of 6%, then we get the monthly rebalancing turnover of 6%*1.75%*109=11.45%. Multiply the monthly turnover of 11.45% by 12, we get the annual turnover rate, 137%. 39 The top eight constituents are considered “tradable” here in the analysis according. 67 ng the two meethodologies, we get comparable annuall turnover ratees. Assume a typical tradinng Comparin cost for reebalancing is 25 basis poin nts.40 Now forr around 137% % or 140% off rebalancing,, we get arounnd 35 basis poin nts. Factoring in other riskss associated with w real estatte trading, a 550 basis points risk premiuum for PurePropeerty seems reaasonable. One thing to keep k in mind iis that the shoort positions aarise only in tthe Brad Casee from FTSE noted that “O property type, t region, or o type/region n combination n indices—noot in the “headdline” all-prooperty, all-reggion index.

The typical allocation to real estate is less than 20% and many institutional investors allocate less than 10% to real estate. The key role real estate plays in a mixed investment portfolio is the foremost physical form of asset with a long-term hold strategy. Real estate is usually considered a channel to store values and is good for inflation hedging. However, real estate is a very illiquid asset which requires specific expertise to run. This is a character that many investors consider risky which puts up a hurdle for them to cross. Real Estate Investment Strategy Real estate investment is a specialized investment in many ways. Many institutional investment companies set up real estate investment divisions to directly invest in properties. Some set up funds and issue bonds while others allocate their own equity in real estate. No specific criteria were given as to who tend to invest directly with their own equity and who tend to manage outside funds to invest in real estate. However, some traditional banks tend to lean on management of outside sources of funds that invest in real estate while some sovereign wealth funds prefer equity investment. Because investing in real estate requires real estate expertise, only certain numbers of institutional investors see real estate as a major investment or key business. There are many real estate investment management companies who just specialize in this industry. When investing in real estate, institutional investors tend to look at several factors: -Nature of the property -Location -Inflation -Growth factor -Management cost -Property depreciation -Local debt market When investing in a local market, investors have addressed the importance of local knowledge, which includes local partners with past working experience and connection in the local market. 72 Global Market Real estate is often considered a local business. When institutional investors look at foreign markets, they tend to be very careful about the selection of properties. Institutional investors look at the big market indicators such as GDP growth, maturity of the real estate market, and local debt market. Developed countries provide stable income stream when investors hold core assets whereas developing countries provide lucrative growth potential. Another key factor is government control and lending policy. This is specifically important in some Asian markets such as China and Vietnam. While the real estate market in China is getting more mature, investors also seek growth potential in high growth markets. For instance, institutional investors mainly focused on the residential sector in the past decade. With residential market cooling down and stabilizing, investors are beginning to look outside the residential market. Service centers started to provide growth potential for investors as demand is growing in both first-tier cities and secondary cities. Such service centers include office and shopping centers, which are still growing in countries like China. In markets like India where there is strict government control, investors also look into the IT industry, such as high-tech campus properties where there is large demand and growth. Further, investors look at the sustainability of the market, the growth of the middle class demographic, and the urbanization movement. Transparency in developing countries is also a concern that global investors expressed. In some regions of the world, deals takes longer time to invest in these countries because of the intermediate process associated with permitting. Illiquidity Liquidity is one major issue for real estate investors. However, for institutional investors who manage a portfolio of assets that sees real estate as one of their investment channels, liquidity is more of a concern on investment of the physical properties than a decisive hurdle. Certain institutional investors tend to act as long-term holders of real estate portfolios and some don’t usually seek opportunistic assets as these assets tend to act as short term investments. Macro-level knowledge of the economic trend and geographic character is more predominant in decision making than individual liquidity. 73 While some institutional investors expressed the concern with illiquidity in real estate investment, they have not largely quantified the illiquidity. Some investors strategically add certain risk premium, but the strategy is more tactic than quantitative, which readdresses the riskiness of real estate investment. As for liquidity in infrastructure, institutional investors also mentioned that the associated risk premium is higher than other assets because it is less frequently traded than equity and bonds due to its nature. Investment Strategy There are several key strategies in the real estate investment. While core assets never go down due to their stable performance and key geographic and demographic feature, there are core-plus assets, which are emerging into a new market because of their growth potential with a character that is close to core asset. Opportunistic assets provide the highest potential return, but it requires the ability to finance as typical Loan-to-value ratio is usually as high as 60%-80%. Market Trend Some institutional investors stated that real estate has been traditionally outperformed the equity market and provides certain degree of diversification thanks to the relatively low correlation with stock. For instance, real estate has a different cycle from stock before the financial crisis in 2008, which allows investors to strategize their investment portfolio accordingly. Further, there is a lag in real estate because of transaction process. Residential real estate was hit hard during the financial crisis. However, commercial real estate has been recovering and has come back relatively strong in the recent period, especially those high quality assets which provide stable healthy income. Infrastructure Investment Infrastructure is a broad term and could include a large scope of assets. While airline and automobile companies can be categorized as infrastructure assets, what institutional investors focus on lately are more tangible assets. Both open-ended and closed-ended funds are used for infrastructure investment as certain assets tend to have different life spans for investment purpose. Below are the four typical infrastructure assets institutional investors focus on: 74 Infrastructure Regulated Utilities Communication Assets Social Infrastructure Transportation Regulated Utilities here refer to companies that own utilities that are regulated. Electric power plant is one regulated utility. Here utility has municipal finance and tax exemption, which provides cheap cost to capital that private equity cannot compete with. Utilities also own a lot of private plants. Communication Assets refer to materials designed to communicate messages to certain audience, either hardcopy or electronic. “Asset types can range from raw materials (imagery, copy blocks, logos, legal text and the like) to a more finished product that combines raw materials to create corporate brochures, sales collateral, annual reports, press releases, contracts/agreements, technical documentation, education & training materials, employee or customer newsletters and more.” 42 Social Infrastructures refer to social facilities such as healthcare facilities including hospitals, healthcare financing, educational system including schools and universities, military facilities and prison. 43 Transportation here refers to railroads, toll roads, and shipping assets.44 There is no perfect infrastructure index that can represent such a broad scope. However, generally speaking, infrastructure here refers to hard assets with long-term income stream and mostly geographically fixed capital. Therefore, investing in infrastructure has the advantage of stable income stream, relative low risk, and stable growth. However, a lot of the infrastructure assets have limited accessibility, and are highly regulated by governmental departments. If privatization or partial opening to private investment are encouraged or expanded, there is great potential in investing in infrastructure. Some institutional investors expressed the shift from investing in infrastructure before the financial crisis to shying away from infrastructure due to the following reasons: 42 SHIFT, http://www.shift365.com/?q=node/13 Wikipedia: http://en.wikipedia.org/wiki/Infrastructure#Social_infrastructure 44 Airports and highways are rarely privatized for trading. Here transportation doesn’t typically refer to the physical assets for airports and highways in the US. 43 75 -In some key markets, infrastructure was not deal flow because of the magnitude of the asset and the holding strategy some investors have. -Vague definition of infrastructure has prevented investors from strategizing a sustainable investment within certain time period. Infrastructure that includes toll roads and railways is usually capital intensive with long-term holding period, which puts up a hurdle for some private equities. Some institutional investors don’t do direct investment in infrastructure because of illiquidity and entry hurdle. Commodity Investment Commodity usually includes natural resources such as electricity, water, oil, raw metal and agricultural products. Institutional investors have expressed their concern with investing in commodity as it is a tricky asset due to its high volatility. Take oil for example, the oil price fluctuates much more dramatically than stock, which shows that commodity exhibits instability and uncertainty for long-term investors. There are commodity ETFs45 daily priced that are linked to the price of crude. If such commodity indexes are linked to miners or plants, then investing in such commodity indexes induce risks due to the equipment associated with them. Hedge funds and high-frequency traders, however, have shown interest in investing in commodity as it provides both short and long opportunities within a relatively short period. As an alternative investment in a mixed portfolio, commodity has not been a major diversifier according to some institutional investors. 45 Exchange-Traded-Funds. Here refers to ETFs that hold commodity. 76 Chapter 8 Final Conclusions The broad scope of real assets has span over various industries and markets. Certain real assets provide investors both growth potential and uncertainty in the investment community. This thesis intends to explore the roles of several selected real assets in a traditional stock-and-bond portfolio, and the findings have indicated the challenges as well as potential in the dynamic management of investment portfolio. Real estate and infrastructure exhibit certain inflation hedging potential thanks to their high correlations with inflation. Commodity and real estate may also contribute to the diversification of an investment portfolio due to their low correlation with stock. The high correlation of infrastructure with stock and a comparable return has somehow prevented infrastructure from dominating in a Sharpe-Markowitz portfolio. However, infrastructure may appeal to those investors who are less risk averse as it provides a more attractive return compared with other real assets. In a stock and bond portfolio, fix-income asset such as long-term government bond has a stable role in all the possible pairing tests and all the Sharpe portfolios. This is in consistence with industry practice.46 When real estate and infrastructure are included in the portfolio, both assets have major roles. These two real assets may have potential in a diversification role. Within real estate, PureProperty, as a separate index, acts slightly more dominant than the private real estate represented by NCREIF NPI. Infrastructure provides attractive return for investors as target return increases in the portfolio structure. However, infrastructure may not perform well in the Sharpe portfolio according to the portfolio analysis. The reason can be attributed to the high volatility of infrastructure and its high correlation with stock. Commodity, on the other hand, has little weight in all of the portfolio pairings and has relatively small contribution in the portfolio despite good diversification effect. The low return and high volatility of commodity may have hampered commodity in the Sharpe efficient portfolio. The high risk of the production process associated with commodity also concerns certain long term investors. And just because of this, commodity provides potential in the derivatives market as hedge fund and other high frequency traders seek out hedging opportunities in the high volatile markets, which is not suitable for those long-only institutional investors. Therefore, commodity should have some specific roles in other kinds of portfolio structures linked to both long and short investors and may not appeal to traditional institutional investors. Another challenge for selecting assets is that historic returns of some assets may be 46 According to the 2012 PREA Investor Report’s plan sponsor asset allocation framework from 1996 to 2010, bonds take up around 25%-30% of the total portfolio. 77 either too high or too low compared with recent figures. Some investors expect that the short-term returns of these assets won’t go back to historic average. The data to include in the selection process will slightly differ per investors’ preference and this will impact the portfolio choice. There are criteria more complicated than purely looking at historic numbers as several recent data reveal changing trends in some industries. This reflects back to the thesis analysis in that the models have their limitations, as the analysis is mostly based on historic data and not on expected targets. However, the analysis looks at portfolios from a long term perspective and examines the diversification for a longer history than what some investors are looking at. A theoretic methodology can definitely adjust to specific investor preference at some point. Using the three different portfolio structures as described in the previous chapters to test out the Value at Risk results, the traditional portfolio with around half the weight to stock, a quarter of weight to long term government bond and the rest distributed to the several real assets47, exhibits a larger loss quantity at 5% percentile of probability within any one year period than the Sharpe portfolios including both standard risk and downside risk. The latter two portfolios have substantial weights on real estate (including NPI and PureProperty), much smaller weight on stock, and a comparable weight on bond with the traditional portfolio. As the Value-at-Risk metrics here are left-hand tail measure, they lean towards the type of risk measures that is similar to downside portfolio optimization analysis. The Downside-risk optimization portfolio weights show slightly better results according to VaR than the Markowitz optimization portfolio. The traditional portfolio created in the VaR is only based on the survey which allocation targets set by real world investors, which are not directly derived through the optimization process based on data used in this thesis. Therefore, it is reasonable to see the result that the traditional portfolio used here does not perform as well as the two optimization models in the Value-at-Risk test. The thesis also intends to quantify the transaction/management cost effect for PureProperty as a way to take in real estate illiquidity in a dynamic investment world. The analysis results in certain haircut to the risk premium associated to real estate and other assets to net out the operating cost. It is an attempt to bring these real assets through more liquid channels in the understanding of the more interactive management of investment portfolios. 47 Using the traditional portfolio model weights from PREA’s survey. 25% to bond as is shown in the sponsor survey by PREA , 55% to stock, and 5% to real estate, PureProperty, commodity and infrastructure for simplicity. 78 It is important to note that with the short time period and limited access to data, there are not yet perfect indexes to represent certain assets such as infrastructure and commodity, which shows the limitation of the research conducted through this thesis. The real world practitioners have more measures to take when managing their investment portfolios. However, the author attempts to take steps further to explore the potential portfolio management strategies and is in hope of contributing some valuable addition to the asset management research field in the days to come! Figure 45 shows how weights change as expected return increases according to different pairings of assets in a stock-and-bond portfolio. It also shows the Sharpe-Markowitz portfolio structure for each pairing. 48 Figure 45-Summary of Portfolio Analysis 48 The histogram on the right of the composition diagram demonstrates the Sharpe-Markowitz portfolio weights for the corresponding pairing. 79 1.
