We find that hedge fund managers who own powerful sports cars take on more investment risk. Conversely, managers who own practical but unexciting cars take on less investment risk. The incremental risk taking by performance car buyers does not translate to higher returns. Consequently, they deliver lower Sharpe ratios than do car buyers who eschew performance. In addition, performance car owners are more likely to terminate their funds, engage in fraudulent behavior, load up on non-index stocks, exhibit lower R-squareds with respect to systematic factors, and succumb to overconfidence. We consider several alternative explanations and conclude that manager revealed preference in the automobile market captures the personality trait of sensation seeking, which in turn drives manager behavior in the investment arena.
