Abstract Text | This thesis examines the risk-return attributes of portfolios screened for ESG factors against those of unscreened portfolios. Key performance indicators are utilized in conjunction with multi-factor models, including the CAPM, Fama-French, and the Carhart models. An ESG factor is then introduced to quantify the ESG premium. The empirical results offer a nuanced perspective: ESG screening neither conclusively reduces portfolio risk nor unambiguously affects diversification. However, the study detects a statistically significant ESG premium, particularly during crises such as the COVID-19 pandemic or the Ukraine conflict. Furthermore, it suggests that ESG-screened portfolios display comparable resilience to their unscreened counterparts during global crises. |
