In this second part, we seek to answer the following question: is there an ESG risk factor? The existence of such a risk factor would imply that ESG discriminates equities between one another. In order to answer this question, we use the ESG composite score to measure the effect of ESG on European equity market’s returns. As a quantitative manager, it seems indeed natural to us to assess the impact of ESG on financial markets through a more objective ESG rating.
