Abstract
Using the measurement and empirical research on the asymmetry of the stock market, this paper confirms risk premium of positive feedback trading asymmetry and its impact on expected returns in China. Through correlation analysis, it is confirmed that the asymmetry factor can represent the trading intensity of retail investors. The A-CAPM model is constructed by incorporating the asymmetry factor into the explanatory framework of stock expected return, and through the significant change of the improved regression intercept term, it is confirmed that the asymmetry factor can better explain the risk premium. Finally, according to the value of the asymmetric factor, the data are divided into four parts, and it is found that the influence of the asymmetric factor on the expected return is opposite to the sign of the factor, and the influence increases with the increase of the absolute value of the factor.
