We propose a new measure, active fundamental performance (AFP), to identify skilled mutual fund managers. AFP evaluates fund investment skills conditioned on the release of firms' fundamental information. For each fund, we examine the covariance between deviations of its portfolio weights from a...

We show theoretically and empirically that flows into index funds raise the prices of large stocks in the index disproportionately more than the prices of small stocks. Conversely, flows predict a high future return of the small-minus-large index portfolio. This finding runs counter to the CAPM,...

We study how passive investing affects asset prices. Flows into passive funds raise disproportionately the prices of the largest stocks in the index, while also making them more volatile. If, in addition, stocks are mispriced because of noise traders, then passive flows raise the most the prices...

This paper studies the role of mutual fund yield in driving investor flows and performance of bond funds. Using two common measures, the SEC yield and 12-month distribution yield, we find strong evidence that investors tend to chase bond funds with higher yields, even after controlling for total...
