Using rich data on familial background of US mutual fund managers, this paper sheds light on the formation of risk preferences by investigating birth order effects. Consistent with sensation-seeking behavior, we find that managers who are born later in the sibling hierarchy take more risks but perform worse relative to lower-birth-order managers. Later-born managers take more extreme style bets, hold more lottery stocks, churn their portfolios more, and engage in more civil and regulatory violations. These birth-order effects are more pronounced when parental resources are limited and age spacing is lower between siblings, suggesting sibling rivalry as a potential mechanism.

Stocks expected to be sold by distressed mega hedge funds (MHFs) face anticipatory institutional selling and increased short interest. However, no evidence of anticipatory trading is found in stocks held by nondistressed MHFs, distressed non-MHFs, or stocks confidentially held by distressed MHFs, suggesting that public portfolio disclosure by large and closely followed distressed investors, and not common investment signals, drives anticipatory trading. Distressed MHFs with greater exposure to such anticipatory trading suffer 2.21% lower style-adjusted returns. Stocks subject to anticipatory trading experience negative abnormal returns followed by reversals, indicating the price destabilizing effect of anticipatory trading.
