Mutual funds hold 32% of the U.S. equity market and comprise 58% of retirement savings, yet retail investors consistently make poor choices when selecting funds. Theory suggests that poor choices are partially due to mutual fund managers creating unnecessarily complex disclosures and fee...

We find AMFs are drawn to, and participate disproportionately more in, earnings announcements (EAs) that include bundled managerial guidance. When the two pieces of news are directionally...

We investigate whether unpleasant environmental conditions affect stock market participants' responses to information events. We draw from psychology research to develop a new prediction that weather-induced negative moods reduce market participants' activity levels. Exploiting geographic...

We re-examine the puzzling pattern of lead-lag returns among economically linked firms. Our results show these patterns are driven largely by investors' tendency to ignore information that arrives continuously in small amounts. In contrast, when information with the same cumulative returns...
