Because average variance and skewness are based on daily returns, whether returns are demeaned should have limited impact. However, it can affect the correlation between these measures and the market return itself. In Technical Appendix Section B.1, we provide additional details on the measurement of average volatility and skewness and discuss an alternative way to construct average skewness, in which we demean daily returns in Eq. (3) using market returns. We find no material difference in the main results. Furthermore, standardizing the skewness using the standard definition of the variance or the corrected version given by Eq. (2) has no substantial impact on the results.
