This study explores the cross-sectional relationship between market beta, sales-to-price, trading volume and stock returns, on Taiwan Stock Exchange from July 1976 to June 1996. Our results show that market beta, trading volume, and sales-to-price seem to have a joint role in explaining the cross-section of average returns. We also find a highly significant conditional relationship between beta and cross-sectional stock returns. These results provide support to continue using beta as a measure of market risk. Finally, our results indicate that the trading volume and sales-to-price effects in average returns are due to investor overreaction.
