Factor Investing in Real Estate: The Performance of Smart Beta Strategies
首次在房地产领域开发并检验基于REITs的因子投资策略，发现除盈利能力外其他因子均有效，且智能贝塔策略能持续跑赢被动持有REITs指数及部分多资产组合。
This article is the first to develop and test factor-based (“smart beta”) strategies in real estate using real estate investment trusts (REITs), the real estate equivalent of stocks. Following the equity pricing literature, the authors construct five factor portfolios—size, value, investment, profitability, and momentum—and analyze their performance from January 1993 to December 2020. The results support all factors except profitability. Building on these factors, the authors design smart beta strategies that integrate the REIT market portfolio with the factor portfolios to optimize asset allocation. These strategies consistently deliver superior risk-adjusted returns relative to a passive buy-and-hold investment in an all-REITs US index. Furthermore, under three of five weighting schemes, the smart beta strategies outperform diversified multi-asset portfolios spanning real estate, equities, bonds, and commodities. This suggests that REIT-based factor strategies can serve as competitive, and at times superior, alternatives to broader cross-asset allocation frameworks.
