Institutional investors' attention to environmental information, trading strategies, and market impacts: Evidence from China

摘要

Using a large proprietary database of intraday high-frequency trading, we investigate the trading strategies of institutional investors in dealing with the negative environmental event disclosure of listed companies and their impact on markets, aiming to reveal the mechanism of the lack of "green efficiency" in China's capital market from the perspective of institutional investors. The results show that institutional investors react to negative environmental events prior to the announcements, indicating premature information leakage in the market; in addition, their trading behaviors mitigate the immediate effect of negative environmental event announcements on stock price. After the event is disclosed, institutional investors engage in short-term selling and long-term buy and hold. This trading strategy undermines the irrational selling of individual investors in the event of disclosure, short-term decline in stock price, and long-term reversal of market overreaction. In a China context, institutional investors generally take environmental information into consideration. However, they fail to recognize the long-term value effect of negative environmental events and instead cater to trading strategies towards market volatility.
