Sweden's fund savings have increased in recent years. Both young and old people have started saving in everything from investment savings accounts to fund accounts, and in 2020, we reached a record level of savings. Funds are the most common way that the Swedish people save, and funds can be managed in different ways, such as through passive or active management. In this study, we have looked at actively managed funds, specifically at the key figure active share and whether this can benefit the returns for funds. The key figure's attribute is to compare the percentage of the fund's total assets that are considered different from the fund's benchmark index. We have chosen to look at a number of Swedish funds between 2018-2022, where we would find out the difference between active funds with a high active share compared to active funds with a low active share. Through our research questions, we have developed various theories and methods to investigate under which circumstance active share affects the return of funds. The conclusion that can be drawn from the various research questions was made through hypotheses about active share to see the key figure's impact on the research questions. Hypothesis one showed that active share has a positive impact on the fund's return when the benchmark index is positive. Hypothesis two shows that the risk-adjusted return is positively affected by active share when the index increases or slightly decreases, but more negatively when the index moves further down. Hypothesis three showed that highly active funds outperformed their benchmark indexes by about 2%. In the last hypotheses, we found that small-cap funds with higher active shares had higher returns than large-cap funds, with a difference of about 3%.
