Using facial width-to-height ratio (fWHR) as a proxy for testosterone, we show that high-testosterone hedge fund managers significantly underperform low-testosterone hedge fund managers after adjusting for risk. Moreover, high-testosterone managers are more likely to terminate their funds, disclose violations on their Form ADVs, and exhibit greater operational risk. We trace the underperformance to high-testosterone managers' greater preference for lottery-like stocks and reluctance to sell loser stocks. Our results prevail with an alternative proxy for testosterone and are robust to adjustments for sample selection, marital status, sensation seeking, and manager race. They suggest that investors should eschew masculine hedge fund managers.
