ESG Incidents and Shareholder Value

ESG Incidents and Shareholder Value

Posted May 28, 2021 at 11:00 am


ESG scores are the modern trend in the financial markets, and while sustainable investing has its critics, it seems to become a regular part of the markets. Frequently, and probably rightfully, ESG is criticized for the lack of commonality across various “scorers”, and as a result, there might be a large dispersion among the score of one firm. The reason is that the score usually consists of different metrics and aggregation methodology. Apart from this “long-term” score, investors can easily recognize the “short-term” score, which can be proxied by negative incidents such as pollution, poor social aspects, social or governance scandals and so on. Moreover, these incidents could be more informative about (un)sustainable practice compared to ESG scores. These ESG incidents are studied by the novel research of Simon Glossner (2021). Using incidents news, the author provides interesting results that mainly support proponents of sustainable investing. Poor ESG performance proxied by incidents predicts more incidents in the future, lower profitability which should subsequently spill to negative performance in future. For example, portfolios consisting of negative incidents stocks significantly underperform the market for both US and European stocks. Therefore, this research paper is a compelling addition to the literature that, apart from social aspects, connects ESG also with performance.

Title: ESG Incidents and Shareholder Value



This paper uses novel environmental, social, and governance (ESG) incident news data to study poor ESG practices. I find that firms’ past ESG incident rates predict more incidents, weaker profits, and lower risk-adjusted stock returns. When examining the cause of these abnormal returns, I find analyst forecast errors as well as lower returns around earnings announcements and subsequent incidents. Moreover, incident rates predict stronger abnormal returns in firms with higher short-term ownership, higher valuation uncertainty, and lower investor attention. Overall, these findings suggest that poor ESG practices negatively impact long-term value, which is not fully reflected in stock prices.

As always we present several interesting figures and tables:
