The study also studied the effect across economy sectors and the results were inconclusive for the period prior to the financial crisis but that the significant outperformance mentioned above drove the industries to all display negative results after the financial crisis. The study also finds... (More)

The study also finds that changes in ESG ratings have no predictive power and provide no new information. This would be in line with the efficient market hypothesis that ESG, as a public information do not provide any information that is not already priced. (Less)
