This study provides an in-depth examination of the relationship between environmental, social, and governance (ESG) performance and the idiosyncratic volatility of Korean companies. In line with the risk-mitigation view, the study finds that strong ESG performance is associated with a reduction in a firm's idiosyncratic volatility. The impact of ESG performance on reducing firm volatility was particularly evident during the COVID-19 pandemic, highlighting the role of ESG performance in risk mitigation during crisis periods. The (...) study also shows that companies with strong ESG performance in industries that are highly sensitive to ESG factors are particularly adept at reducing idiosyncratic volatility. These findings underscore the importance of ESG enhancement for both firm managers and policymakers, particularly within ESG-sensitive industries. (shrink)

This article examines the risk and return profiles of stock indices composed of companies meeting environmental, social and governance screening criteria [such as the Dow Jones Sustainability Indices ] and conventional composite indices of eight Asian countries from 2002 to 2014. The results indicate that there are no significant differences in the returns or risk-adjusted returns between the ESG indices and the composite indices within countries. The results do reveal that the market volatility of the ESG (...) indices is higher than the market volatility of the conventional indices. Market betas of DJSI and ESG equity indices are significantly lower than betas of the composite equity indices. The overall results indicate that the performance of ESG equity indices of many Asian countries is similar to the performance of conventional indices, suggesting that investors can pursue socially responsible investing objectives without a material difference in portfolio performance from conventional investing.

This study examines the volatility risk for firms that are rated high on environmental, social, and governance (ESG) dimensions in emerging markets and developed markets outside the United States and Canada. Employing the Morgan Stanley Capital International (MSCI) ESG Leader indices, this study investigates the impact of good news and bad news on the volatility risk for the highest ESG-rated firms through multivariate DCC-EGARCH modeling. This study finds that the impact of a negative news shock (...) of size 2 standard deviations is approximately 45% higher than that of a positive news shock of the same size for the case of the developed markets under interest. With respect to emerging markets, this study reports that the impact of a negative news shock of size 2 standard deviations is 41% higher than that of a positive news shock of the same size. The results provide empirical evidence in support of the hypothesis that the volatility impact of news for high ESG-rated firms in developed markets and emerging markets is larger for bad news compared to good news, and the results are robust across time. The empirical findings underline the importance of reporting-related disclosures of ESG initiatives, and provide seminal evidence of a slow response to news by high ESG-rated firms in emerging markets.

This study analyzed the sensitivity between fund flow and fund performance with Korean funds, whether there would be a difference in the sensitivity between environmental, social and governance funds and non-ESG funds, and whether there was a difference in sensitivity according to the type of past fund performance. The main results of the analysis are as follows. First, the analysis of the fund flow–performance correlation of Korean funds revealed that they had a negative correlation and the ESG (...) did not affect fund flow. Analysis of the difference in sensitivity between fund flow and performance volatility revealed that there was a negative correlation regardless of the performance measuring method and ESG. Finally, the comparison of fund flow and performance sensitivity according to the type of past fund performance revealed that despite consistent asymmetry, there was little difference in sensitivity asymmetry between ESG funds and non-ESG funds. The results reveal that, unlike the expectation that investors in Korean ESG funds would focus more on non-financial properties like the purpose of investment than on profit, they attach the same importance to fund performance.

Although legitimacy theory provides strong arguments that environmental, social and governance disclosure and performance can help mitigate firm-specific risks, this relationship has been repeatedly challenged by conceptual arguments, such as ‘transparency fallacy’ or ‘impression management’, and mixed empirical evidence. Therefore, we investigate this relationship in the revelatory case of initial public offerings, which represent the first sale of common stock to the wider public. IPOs are characterised by strong information asymmetry between firm insiders and society, while at (...) the same time suffering from uncertainty in firm legitimacy, culminating in amplified financial risks for both issuers and investors in aftermarket trading. Using data from the United States, we demonstrate that voluntary ESG disclosure reduces idiosyncratic volatility and downside tail risk and higher ESG ratings have lower associated firm-specific volatility and downside tail risk during the first year of trading in the aftermarket. We provide theoretical arguments for the relationships observed, suggesting that companies striving for ESG performance and communicating their efforts signal their compliance with sustainability-related norms, thus acquiring and upholding a societal license to operate. ESG performance and disclosure help companies build their reputation capital with investors after going public. We also report that ESG disclosure is a more consistent proxy for ex-ante uncertainty as an indicator of aftermarket risk, thereby replacing some of the more conventional measures, such as firm age, offered in the existing literature.
