Monetary Policy and the Cross-Section of Security Returns
Posted: 1 Feb 2001
Ample evidence shows that size and book-to-market equity explain significant cross-sectional variation in stock returns, whereas betas contribution is minimal or nonexistent. Recent studies also demonstrate that proxies for monetary stringency increase the explained variation in stock returns. We reexamine a three-factor model that includes beta, size, and book-to-market equity, while allowing monetary conditions to influence the relations between these risk factors and average stock returns. We find that ex-ante proxies for monetary stringency significantly influence the relations between stock returns and all three risk factors. Additionally, all three variables are found to contribute significantly to explaining cross-sectional returns in a three-factor model that includes the monetary sector.
