This study analyzes 66 Swedish actively managed mutual funds investing in the Swedish stock market during the period 2005-2014. The purpose is through pooled data regressions analyze the relationship between both the mutual fund’s annual fee and risk-adjusted return to the fund’s characteristics. The characteristics of the study are the size of the fund's assets, age, if the fund is bank managed or not, Tracking Error, and standard deviation of return.By using the performance measures of CAPM, Fama and French 3-factor model, and Carhart’s 4-factor model monthly risk-adjusted returns are created for all funds over the period. Two pooled data regressions are performed with the Fixed Effect Model in which the annual fee and risk-adjusted return is set up as explanatory variables against the various characteristics.The results of the study show a clear correlation between annual fee and tracking error against the risk-adjusted return. A higher fee adds value to the investor through a higher risk-adjusted return, but will not fully compensate for the increased fee. The relationship between Tracking Error and risk-adjusted return is negative, which means that mutual funds that are distant from its benchmark perform worse than the mutual funds close to its benchmark. To explain annual fee this study finds low economic significance for the characteristics included. Although several variables show statistical significance, it is difficult to say anything about the characteristics that affect a mutual fund's annual fee due to the weak economic significance.

Over the past decades, investing and saving in mutual funds has become a popular alternativefor generating returns. Interest continues to grow and is widespread among different types ofinvestors, ranging from small-scale savers to professional investors, as well as differentgeographic markets. As interest and investment has grown, so has the range of fundsavailable, and with it the range of focused funds. Among these are real estate funds, fundsconsisting of holdings in the real estate market including different types of real estatecompanies and property-related assets. The ownership of funds is associated with a fee to cover various costs associated withoperating the fund. These fees can vary greatly in size across fund types and managers andaffect the fund’s performance and returns. Fees in relation to return have been researchedwith varying results and with the rise of focused funds, the authors felt that it should befurther investigated. The purpose of this study was thus formulated to investigate whetherthere is a relationship between fund fees and returns for real estate funds. This in turn toanswer whether it is justified for fund managers to charge a higher fee and to examine if theTheory of an Efficient Market holds or not. For this, a total sample of 69 real estate fundsfrom the Swedish, Norwegian and Finnish markets during a 3 year period from 1th of January2020 to the 31th of December 2022 was examined. In summary, based on the conducted regression analyses, it can be inferred that the results,similar to previous research, vary. However, it can be observed that there is a negativerelationship between fund fees and the risk-adjusted returns of real estate funds whenanalysing funds that have been active throughout the examined period. The analyses alsoreveal that the age and size of the funds have an impact on the risk-adjusted returns, whereyounger funds with large assets generate higher returns. This means that young real estatefunds with large assets and lower fees generate higher returns compared to older funds withsmall assets and higher fees. Consequently, it is not justified for managers to charge higherfees, nor for investors to pay them. Investors seeking to maximise their returns are thereforeadvised to choose real estate funds with low fees. Finally, based on this, it can be assumedthat the Theory of Efficient Markets holds for real estate funds in the Swedish, Norwegian,and Finnish markets.
