Mutual Fund Hedging Demands and the Cross-Section of Variance Risk Premiums

Abstract

This paper empirically studies whether institutional stock holdings predict equity option returns. I find that institutional concentration in the underlying stock negatively predicts the cross-section of corresponding option returns. Evidence is consistent with a hedging and demand pressure channel: For stocks with more concentrated ownership, some institutional holders are more likely to overweight them and demand more of their options to hedge. To absorb the order imbalances, dealers sell options and charge higher prices, leading to lower option returns. Using option holdings of U.S. equity mutual funds, I document a positive correlation between funds' stock concentration and their option share in the same firms.
