Abstract

We provide strong empirical evidence that asset excess returns can be predicted using the CAPM. When predicting next month's excess returns, the CAPM yields an out-of-sample R2 of about 4% across all portfolios and of about 2.7% across all S&P 500 stocks. That is, the predictive power of the market return predictor transmits to the product of the asset's beta and the risk premium of the market. As a consequence, strategies exploiting the predictive power of the CAPM have Sharpe ratios up to 100% larger than those of the corresponding buy-and-hold strategies.

Keywords: capital asset pricing model, predictability, cross-section of stock returns
