Abstract
We study the pairwise stock return correlations. We find that 90% of the
variation in correlations is not explained by the explanatory variables.
We also conduct an APT test based on the idea that stocks with high
correlations should have similar expected returns. We find evidence
consistent with this implication of the APT. Finally, trading stocks
that deviate from their comovers is highly profitable.
