This research examines whether Corporate Social Responsibility (CSR) initiatives impact fund financial performance of 46 Nordic mutual funds during the past five years (2016-2020). Previous studies have focused on which of the two alternatives generates a rewarding financial result. To complement previous research, this study focuses on the development of CSR - whether the gap formed between CSR initiatives and fund financial performance is moving closer towards each other based on the increased focus of ESG factors during the recent years. Two categories, strong and weak ESG performance, are juxtapositioned to find out at what stage the development is. Furthermore, analysis on which of the three categories: environmental, social or governance individually, is the driving factor of the development of CSR initiatives. Based on the matched pair methodology and hypothesis testing, funds with CSR initiatives have reached the point, in which they perform equally well to their peers without such motives. The underlying driver behind the development are examined.
