Abstract

This paper evaluates how Chinese stocks respond to the onboarding of China-focused ESG scores on the Bloomberg Professional Terminal in the short term. By utilizing the event study approach, we find that the top 10 % of ESG-rated stocks react significantly positively to the onboarding event, whereas the bottom 10 % of ESG-rated stocks experience significant and negative cumulative average abnormal returns. Moreover, this effect is asymmetric in that the negative returns have a greater and more prominent magnitude than the positive returns. By comparing the cross-sectional data results before and after the rating event, we propose several channels through which these effects may function. The findings of this study also have economic and policy implications for investors and policy-makers.
