This study shows how investing in mutual funds involves an additional risk, which we call management risk as a consequence of the uncertainty in the results of active management. To address this issue, we analyze a sample of 2,539 US equity mutual funds. For comparative purposes, we differentiate among index funds and actively managed mutual funds with different investment styles. We observe that performance distribution shows negative mean, negative skewness, and excess kurtosis. Results also show that management risk is not rewarded with higher abnormal performance. Moreover, higher active management prices are linked to funds with higher management risk and negative asymmetry. Therefore, investors seem to be risk-seeking since they are paying more to participate in high asymmetric bets.Finally, we attempt to solve this puzzle from the behavioral finance perspective.
