I provide evidence that fund managers who overweight firms with the most differentiated products ('monopolies') exhibit a superior risk-adjusted performance. This is consistent with information advantages due to a better understanding of qualitative information on a firm's competitive...

We study the dynamics of fund manager ownership for a sample of U.S. equity mutual funds from 2005 to 2011. We find that ownership changes positively predict changes in future risk-adjusted fund performance. A one-standarddeviation increase in ownership predicts a 1.6 percent increase in alpha...

Processing qualitative information about a firm's product market competition matters for fund performance. I find that fund managers with a better understanding of a firm's market power exhibit a superior risk-adjusted performance. Managers who overweight companies with the fewest competitors...

We show a long-lasting association between a common societal phenomenon, early-life family disruption, and investment behavior. Fund managers who experienced the death or divorce of their parents during childhood take lower risk and are more likely to sell their holdings following riskincreasing...

We study whether investors' demographic similarity to CEOs affects their investment decisions. Mutual fund managers are found to overweight firms led by CEOs who resemble them in terms of age, ethnicity and gender. This finding is robust to excluding educational and local ties and is supported...

Mutual fund investors are supposed to make long-term investments instead of striving for quick fortunes. However, the dynamics of funds' ability to generate abnormal returns over their lifetime is still an unattended issue. This paper provides evidence on the liability of newness and liability...

This paper proposes several new holdings-based measures of fund investment horizon, and examines the relation between manager skills and fund holding horizon. We find that both aggregate holdings and trades of long-horizon funds are informative about superior future long-term stock returns,...

We develop a new tail risk measure for hedge funds to examine the impact of tail risk on fund performance and to identify the sources of tail risk. We find that tail risk affects the cross-sectional variation in fund returns, and investments in both, tailsensitive stocks as well as options,...

Processing qualitative information about a firm's product market competition matters for professional investors. Consistent with a superior understanding of a firm's market power, fund managers who overweight companies with the fewest competitors (monopolies) outperform their peers. An exogenous...

This study provides evidence that investors' demographic similarity to CEOs facilitates informed trading after accounting for selective distribution of information. Mutual fund managers overweight firms whose CEOs resemble them in terms of age, ethnicity, and gender. Significantly higher trade...
