Have Hedge Funds Solved the Idiosyncratic Volatility Puzzle?

Abstract: This paper examines idiosyncratic volatility of equity-oriented hedge funds and provides an explanation for why there exists a positive cross-sectional relation between funds’ idiosyncratic volatility and their future returns, whereas higher idiosyncratic volatility predicts lower returns in the cross-section of individual stocks. We find that idiosyncratic volatility is a persistent hedge fund characteristic and positively linked to proxies for managerial incentives, discretion, and leverage. Moreover, funds with a greater value of long call options and confidential equity positions disclosed with a delay in their regulatory filings exhibit higher idiosyncratic volatility. We document a positive (negative) cross-sectional relation between idiosyncratic volatility and future returns on individual stocks with high (low) hedge fund ownership. The results indicate that hedge funds are able to solve the idiosyncratic volatility puzzle by successfully picking undervalued, high-volatility stocks that offer high future returns and shying away from overvalued, high-volatility and lottery-like stocks that offer low future returns.
