We study the interdependencies between transaction costs, portfolio characteristics, and mutual fund performance. Using a novel dataset of actual mutual fund trades, we find that, controlling for investment style, larger funds realize lower percentage transaction costs than smaller funds. Larger...

We document statistically significant relations between fund beta and past market returns that affect standard estimates of mutual fund market timing. Our evidence of “artificial” market timing emerges when we estimate market timing regressions across time periods that span time variation in...

Mutual fund returns are significantly related to stock characteristics in the cross section after controlling for risk via factor models. We develop a new double-adjusted approach that controls for both factor-model betas and stock characteristics in one performance measure. The new measure...
