We examine whether the stock return performance of 620 Eurozone companies based on their ESG ratings both before and during the Covid-19 pandemic on both a nominal and risk adjusted basis. We also look at how country level governance indicators interact with our samples of ESGHigh and ESGLow companies to affect both nominal and risk adjusted investment returns. We use both panel data and cross-sectional regressions as well as the difference-in-differences approach to derive the empirical results. We generally find some evidence that highly rated ESG firms performed slightly worse than lower rated ESG both overall and during the pandemic. However, once we control for governance at the country level, we find that in high governance scoring countries ESGHigh companies perform better than ESGLow companies. Finally, when we examine the relative performance of EU companies compared to companies in economies less impacted by the Covid-19 pandemic, namely South Korea and Australia, we find that during the pandemic, the South Korean and Australian companies performed much better than their counterparts in Europe.
