Using MSCI ESG indexes, the study reveals a slight decrease in financial returns with higher screening intensity. Well-diversified ESG indexes showed no reduced returns compared to a non-restricted index. Surprisingly, monthly vari ance across indexes remained equal regardless of the screening intensity. Jensen's alpha estimation found no significant differences in risk-adjusted returns among the observed ESG indexes. These findings build on previous literature and shed light on the complexities of ESG strategies within investment landscapes.engEsg (environmentalSocialGovernance)Investment strategiesInvestment performanceEsg screeningsmaster thesis203681150
