تمایلات سرمایه و اثر غیر خطی آن بر بازار سهام شواهدجدید از بازده سهام چین بر اساس مدل رگرسیون چندک پانل

This paper employs the panel quantile regression model to study the nonlinear effect of investor sentiment on monthly stock returns in the Chinese A-share stock market. The findings show that the influence of investor sentiment is significant from 1 month to 24 months. Its effect is asymmetric and reversal, that is, it is positive and large for stocks with high returns in the short term while negative and small in the long term. This reversal effect verifies the existence of a strong overreaction in the Chinese stock market. We also find that Chinese investors have notable cognitive bias and speculation tendency.
