| Summary: | This thesis aims to examine the relationship between ESG (Environmental, Social and Governance) ratings and the performance of European stocks. The purpose of this study is to examine the existing evidence pertaining to this relationship and the contradictory results that have been offered by previous scholars. The sample used includes ESG and stock return data from Refinitiv for the years 2010 to 2021 on the European market (Austria, Belgium, Denmark, Finland, Germany, Greece, Iceland, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom). An ESG portfolio approach is used as the econometric framework, where performance evaluation models such as the CAPM model developed by Sharpe (1964), Lintner (1965), and Mossin (1966), Fama- and French (1992) 3-factor and Carhart (1997) 4-factor models are applied. The results obtained from this study could not show any significant alphas to prove a relationship between ESG ratings and stock performance. Thus, no abnormal returns should be expected by investors that use an active investment strategy based on ESG screening.
