Skewness of returns is used as the main criterion to verify the existence of asymmetries in stock returns on the Iranian Stock Exchange member firms. Correlation between skewness in stock returns in the categories of book value to market value of the shares at the top (or bottom) shows the trends of negative (or positive) in stock returns. Based on the findings, the value or glamour-stock puzzle is partially described by investor preference for positive skewness in stock returns. Such preference for skewness is in accordance with the investor's preferences, which have inverse S-shaped utility functions. This paper offers some further evidences of the significant predictive power of accounting-based measures, such as book rate of returns, for skewness of stock returns.
