Expected stock returns and volatility
In the cross'section of equity option returns, returns on call (put) option portfolios decrease (increase) with underlying stock volatility. This finding is not due to cross We examine how volatility risk, both at the aggregate market and individual stock level, is priced in the cross-section of expected stock returns.

A trading strategy buying stocks in the highest implied volatility quintile and shorting stocks in the lowest implied volatility quintile generates insignificant returns.
