Abstract

We show that microstructure biases in the estimation of expected option returns and risk premia are large, in some cases over 50 basis points per day. We propose a new method that corrects for these biases. We then apply our method to real data and produce three main findings. First, the expected returns of straddles and delta-hedged options written on the S&P 500 Index are smaller than previously estimated in the literature. Second, delta-hedged options and straddles written on individual stocks have negative expected returns. Third, the price of individual equity volatility risk is about 45% of the price of market volatility. These findings show that the stylized finding that volatility is not priced in individual stock options is due to microstructure biases.
