The Market Timing Power of Moving Averages: Evidence from US REITs and REIT Indexes
University of Adelaide Business School
November 14, 2012
I present evidence that a moving average trading strategy dominates buying and holding the underlying asset in a mean-variance sense using monthly returns of value-weighted and equal-weighted US REIT Indexes over the period January 1980 until December 2010. The abnormal returns are largely insensitive to the four Carhart (1997) factors and produce economically and statistically significant alphas of between 10% and 15% per year after transaction costs. This performance is robust to different lags of the moving average and in subperiods while investor sentiment, liquidity risks, business cycles, up and down markets, and the default spread cannot fully account for its performance. The MA strategy works just as well with randomly generated returns and bootstrapped returns. The substantial market timing ability of the moving average strategy appears to be the main driver of the abnormal returns. The returns to the MA strategy resemble the returns of an imperfect at-the-money protective put strategy relative to the underlying portfolio. The moving average strategy avoids the sharp downturn at the beginning of 2008 and substantially outperforms the cumulative returns of the buy-and-hold strategy using all of the 20 REIT Indexes. The results from applying the moving average strategy with 274 individual REITs largely corroborate the findings for the REIT Indexes.
