报告内容:

This study investigates how stock price informativeness (SPI) is jointly affected by the performance (“doing good”) and disclosure quality (“speaking well”) of financial and non-financial Environmental, Social, and Governance (ESG) information. We find that both “doing good” and “speaking well” improve SPI, and the latter strengthens the effect of the former, regardless of financial or non-financial information. Non-financial information complements financial information in shaping SPI, which is particularly influential when financial information is poor. This effect propagates through three channels: analyst attention, information asymmetry, and institutional ownership. Our findings highlight the nuanced interplay between financial and non-financial information, revealing that disclosure quality contributes to incremental informational value beyond performance metrics. The results are further validated through the out-of-sample performance of strategically constructed portfolios, which enable us to propose a double-dual signaling framework for sustainable investment strategy, and provide practical guidance for investors' asset allocation decisions.
