Social responsibility has gained popularity during the past few years, and one aspect of it is what benefits and costs it brings to a socially responsible investor. The purpose of this study is to examine whether different SRI strategies used by mutual funds are related to financial performance. By using multiple regression analysis and a sample of 88 Swedish SRI mutual funds over the period from 2014 to 2018, we find that using SRI screens first reduces the financial performance, but then gains a slight rebound as the screening intensity increases, indicating a U-shaped relationship. Further, we find that environmental screens impact the financial performance positively, and engagement and voting in sustainability matters is also positively related to performance.
