Updated CEM Benchmarking Study Highlights REIT Performance

18-year study reveals allocations, returns, volatility and risk-adjusted performance of 12 asset classes.

CEM Benchmarking’s 2017 study, sponsored by Nareit, provides a comprehensive look at realized investment performance across asset classes over an 18-year period using a proprietary dataset covering more than 200 public and private sector pensions with nearly $3.5 trillion in combined assets under management. One of the unique benefits of the CEM dataset is that it provides the actual realized performance net of investment costs of the assets chosen by plan managers and trustees.

The study compares gross and net average annual total returns as well as correlations and volatilities for 12 asset classes with appropriate adjustments for reporting lags associated with illiquid asset classes (unlisted real estate and private equity).

Highlights:

  • REITs had the highest average annual return of the 12 asset classes covered in the study.
  • REITs had relatively low correlation with non-real estate asset classes.
  • REITs had the highest non-fixed income risk adjusted return.

Returns

Over the 18-year period covered by the study there are striking differences in performance across asset classes. The chart below summarizes average annual net returns and expenses for the 12 asset classes.

  • Listed equity REITs had the highest average net return over the period, averaging 11.4 percent. Private equity had the highest average gross return, estimated as 13.1 percent, but had the second highest average net return of 11.1 percent because of the impact of expenses.
  • Unlisted real estate produced average net returns of 9.3 percent over the period, nearly 20 percent less than REITs.
  • The two worst performing asset classes were hedge funds/tactical asset allocation (TAA) strategies and U.S. other fixed income. U.S. other fixed income however includes cash. If cash is excluded from U.S. other fixed income as an aggregate asset class, then hedge funds/TAA would have been the worst performing asset class with an 18-year arithmetic average annual net return of 5.1 percent.

 

Correlations

The study computed correlations of annual returns among the 12 asset classes. The table below summarizes some key correlations between broad equities, REITs and unlisted real estate.

  • As highlighted in green, REIT and unlisted real estate returns were highly correlated when illiquid returns are adjusted for reporting lags. The correlation is measured as .92. The high correlation is not surprising given the similarities in underlying assets.
  • As highlighted in dark blue, REIT and unlisted real estate returns had relatively low correlations with listed equity returns. These relatively low correlations reflect the well-known diversification benefits associated with the real estate asset class, whether REITs or unlisted real estate.

Volatilities and Risk Adjusted Returns

The study also compared volatilities and risk adjusted returns using the Sharpe ratio across asset classes. The data are summarized below.

  • Two fixed income asset classes had the highest Sharpe ratios reflecting their extremely low volatilities albeit modest returns.
  • Outside of fixed income, REITs had the highest Sharpe ratio measuring .44, reflecting their high returns and just above average volatility. Unlisted real estate had a much lower Sharpe ratio measuring .31, reflecting lower returns and comparable volatility to REITs.
  • After adjusting for valuation lags, the study found that REITs and unlisted real estate had comparable volatilities. REITs and unlisted real estate had the fourth and sixth most volatile net returns with measured volatilities of 20.7 percent and 19.0 percent respectively. As with correlations, the similarity in volatilities is not surprising given that listed equity REITs and unlisted real estate have the same underlying assets.
  • Non-U.S. stock and hedge funds/TAA had the lowest Sharpe ratios reflecting high volatility and poor returns, respectively.
  • After adjusting for valuation lags, private equity was by far the most volatile asset class at 28.0 percent.

Conclusion

CEM Benchmarking used its unique proprietary dataset which is comprised of asset level return data for hundreds of U.S. pension funds with more than $3 trillion in assets. The CEM analysis concluded that over the 18-year period of study covering the years 1998 to 2015, REITs had the highest average annual net return, relatively low correlations with other asset classes, implying good diversification benefits, and strong risk adjusted returns.
