This article presents evidence on predictability of excess returns for equi
ty REITs relative to the aggregate stock market, small-capitalization stock
s, and T-bills using best-fit models from prior time periods. We find that
excess equity REIT returns are far less predictable out-of-sample than in-s
ample. This inability to forecast out-of-sample is particularly true in the
1990s. Nevertheless, in the absence of transaction costs, active-trading s
trategies based on out-of-sample predictions modestly outperform REIT buy-a
nd-hold strategies. However, when transaction costs are introduced, profits
from these active-trading strategies largely disappear.
