Using monthly returns for over 37,000 stocks from 46 developed and emerging market countries over a two-decade period, we test whether empirical asset pricing models capture the size, value, and momentum patterns in international stock returns. We propose and test a multi-factor model that includes factor portfolios based on firm characteristics and that builds separate factors comprised of globally-accessible stocks, which we call “global factors,” and of locally-accessible stocks, which we call “local factors.” Our new “hybrid” multi-factor model with both global and local factors not only captures strong common variation in global stock returns, but also achieves low pricing errors and rejection rates using conventional testing procedures for a variety of regional and global test asset portfolios formed on size, value, and momentum.
