Using a sample of daily net flows to nearly 1,000 U.S. mutual funds over a year and a half period, we identify a set of systematic factors that explain a significant amount of the variation in flows. This suggests the existence of a common component to mutual fund investor behavior and indicates...

We use a two-year panel of individual accounts in an Samp;P 500 index mutual fund to examine the trading and investment behavior of more than 91 thousand investors who have chosen a low-cost, passively managed vehicle for savings. This allows us to characterize investors' heterogeneity in terms...
