Do the Goal Sanctify the Mean? : An event study of how the Swedish market reacts to ESG news

Abstract: The primary objective of profit-maximizing companies has long been seen as satisfying its shareholders. However, this orthodox view of corporate governance has been modernized as corporate social responsibility have become more relevant. In essence, corporate sustainability performance has evolved and is now divided into environmental, social and corporate governance, also known as ESG, closely scrutinized by all stakeholders.  The main purpose of this study is to investigate how ESG disclosures about Swedish-listed companies affect their market value. By analyzing these results, using both conventional and complementary theories in behavioral finance, the researchers in this study also aspires to add new perspectives to the research field on why and how the market reacts as it does. This aim was then fulfilled by quantifying the impact of 195 ESG news on market capitalization using three-event studies.  The results are sufficiently reliable to confirm both hypotheses of the study. The findings support both theories and previous research in the sense that deviations from the social contract between firms and stakeholders damage firms' legitimacy. Furthermore, the study’s results show that market reactions are asymmetric. Firstly, with the implication that the negative impact of negative news exceeds the corresponding positive impact of positive news. Secondly, with the meaning that positive news results in a negative impact on market value.  This can be attributed to market psychological factors and other factors, such as Swedish investors' valuation of sustainability work. In addition, the opposite market reaction to positive news is consistent with studies suggesting that certain ESG news are perceived as greenwashing. Against this background, the study concludes that companies' sustainability work and ESG compliance are not profitable to the extent previously advocated. However, the indirect cost of not acting in a socially responsible manner is greater than the opposite.
