- REITs had the third highest average annual return of the 12 asset classes covered.
- REITs had a low correlation with equities.
- REITs had the second highest non-fixed income risk adjusted return.
About the Study
CEM Benchmarking’s 2022 study, sponsored by Nareit, provides a comprehensive look at realized investment performance across asset classes over a 23-year period (1998-2020) using a unique dataset covering over 200 public and private sector defined benefit (DB) pensions with nearly $3.9 trillion in combined assets under management. Unlike index based research, the CEM dataset provides the actual realized performance of the assets chosen by plan managers and trustees.
Over the 23-year period covered by the study there are striking differences in performance across asset classes. The figure below summarizes average annual net returns and expenses for the 12 asset classes.
- Listed equity REITs had the third highest average annual net return over the period, 10.0%.
- Unlisted real estate produced average net returns of 7.8% over the period, over 200 basis points 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.
REIT Performance vs. Private Real Estate in DB Plans
Unlisted or private real estate can be accessed through a number of different ownership styles each with different risk profiles and costs. CEM provides comparisons of returns, correlations and volatilities for each of the four key private real estate ownership styles:
- Internally Managed Direct
- Core Funds
- Value Added / Opportunistic Funds
- Fund of Funds.
The figure below summarizes net returns by style and shows that irrespective of ownership style, REITs outperform private real estate.
The study computed correlations of annual returns among the 12 asset classes. The correlation 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 .84. The high correlation is not surprising given the similarities in underlying assets.
- As highlighted in green, REIT and unlisted real estate returns had relatively low correlations with bonds and 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.
- Outside of fixed income, REITs had the second highest Sharpe ratio measuring .45, reflecting their high returns and just above average volatility. Unlisted real estate had a much lower Sharpe ratio measuring .32, 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 measured volatilities of 18.5% and 17.4% respectively. As with correlations, the similarity in volatilities is not surprising given that REITs and unlisted real estate have the same underlying assets.
- After adjusting for valuation lags, private equity was by far the most volatile asset class.
CEM Benchmarking used its unique proprietary dataset which is comprised of asset level return data for hundreds of US pension funds with nearly $3.9 trillion in assets. The CEM analysis concluded that over the 23 year period of study covering the years 1998 through 2020, REITs had the third highest average annual net return, relatively low correlations with other asset classes, implying good diversification benefits, and strong risk-adjusted returns.
The study also found that REITs outperform private real estate irrespective of ownership style.
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).
The 2022 study also compares the performance of different styles of unlisted real estate including internally managed, core, value added/opportunistic, and fund of funds.
