This thesis aims to investigate whether active or passive fund management provides the most risk-adjusted return over a given ten-year period on the Swedish market. The investigation is conducted for 21 active funds and 7 passive funds by using closing prices for all funds for all weeks between 2012-01-01 and 2021-12-31. Different performance measures have been used in this thesis, to gain a better picture of actual performance of each fund. The performance measures used are, Jensen’s alpha, beta, Sharpe Treynor, Information and Sortino ratio. Followed up with calculation of the Capital Asset Pricing Model (CAPM) and analyzing it to the total return for the funds. The data provided is retrieved from Thomson Reuters Datastream and with the help of Microsoft Excel the data will be processed. Also provide developed performance measures for all the funds included. Also, analysis whether active or passive managed funds are more favorable for the investors are included in the thesis. After calculating the performance measures for all funds, is has been shown that active managed funds performed better than passive funds and the benchmark index. However, when running a regression to see the relationship between the total net return of active funds and CAMP, then comparing it to the relationship between the total net return of passive funds and CAMP passive funds. It turned out that passive managed funds performed better, and this with statical significance.
