Abstract: Stock returns demonstrate different levels of sensitivity to marketwide sentiment fluctuations. Previous studies argue that stock sentiment risk is caused by information opacity and that companies lacking information transparency tend to be young, small, paying no dividend, volatile, and fast growing. However, little direct evidence exists regarding the impact of information transparency on stock sentiment sensitivity/beta. This paper contributes to fill this gap by employing proximate measures of information transparency: quality of accruals and earnings, and accuracy of analyst forecast. Empirical results validate that information transparency indeed helps curb stock sentiment beta. Such an impact is more pronounced during periods of low market sentiment when irrational investors are mostly sidelined. Two mediating factors are identified: noise trading and stable institutional shareholding. Additionally, improving information transparency on corporate governance also constrains stock sentiment sensitivity. Our results are robust to alternative measures and the endogeneity concern.
