We uncover extensive evidence of out-of-sample return predictability for industry portfolios based on a principal component approach that incorporates information from a large number of predictors. Moreover, we find substantial differences in the degree of return predictability across industries. To understand these differences, we propose a decomposition of out-of-sample industry return predictability into beta and alpha shares, where the former corresponds to a conditional beta pricing model. A conditional version of the popular Fama-French three-factor model accounts for nearly all out-of-sample industry return predictability, with exposures to time-varying market and size risk premiums especially important for explaining differences in return …
