Förvaltning och avkastning hos fonder har forskats om i flera studier runt om i världen. Tidigare forskning har gett varierande resultat, där vissa studier visar på att det föreligger ett samband mellan en fonds avgift och avkastning, medan andra inte kan säkerställa ett sådant resultat. Då de svenska hushållen idag sparar mer än någonsin, visar det på att fondsparande är ett aktuellt ämne för ytterligare forskning. Statistik från 2020 visar att fondförmögenheten i Sverige totalt uppgick till 4 554 miljarder kronor och har visat på en fortsatt ökande trend de senaste åren. Dock har endast få studier genomförts på den svenska kapitalmarknaden och de har i huvudsak analyserat ämnet på kort sikt, med en tidsperiod om fem år. Eftersom avgifternas påverkan på fonder är tydligast på lång sikt, ger det utrymme för fortsatt forskning inom ämnet. Syftet med följande forskning är att studera sambandet mellan svenska aktiefonders avkastning och avgift på lång sikt i förhållande till fondernas risk. Studien avgränsas till att undersöka svenska aktiefonder som har varit verksamma i minst tio år, mellan åren 2011-2020. Forskningen antar en kvantitativ forskningsmetod, vilket syftar till att testa teorier. Tillvägagångssätt sker genom en analys av urvalets regression och korrelation i samband med hypotesprövning, där variabler undersöks för att ge underlag till studiens analys av resultat. Studiens resultat visar att svenska aktiefonder i genomsnitt underpresterar den svenska marknaden på lång sikt. Forskningen visar även varierande resultat gällande korrelation mellan riskjusterad avkastning och avgift på lång sikt. Resultaten indikerar att den svenska kapitalmarknaden har en relativ marknadseffektivitet av svag form. I tillägg verkar aktivt förvaltade fonder kunna utnyttja tillfällig trendidentifiering och informationsasymmetri för att uppnå en överavkastning. Forskningen avslutas med slutsatsen att högavgiftsfonder, vilka är mer aktivt förvaltade, indikeras vara ett bättre investeringsalternativ för att uppnå en god långsiktig prestation i jämförelse med passiva fonder. / The management and return of funds have been researched in many studies around the world. Previous research has yielded varied results, with some studies showing that there is a link between a fund's fee and return, while others cannot ensure such a result. As Swedish households save more today than ever, it shows that fund saving is a current topic for further research. Statistics from 2020 show that fund assets in Sweden are 4 554 billion swedish crowns in total, a number that has continuously grown in the past years. However, only a few studies have been conducted on the Swedish capital market where the existing studies have mainly analyzed the subject in the short term, with a time period of five years. Since the impact of fund fees is most noticeable in the long term, the subject can be further explored.  The aim of this research is to study the correlation between returns and fees of Swedish equity funds in the long term in relation to the funds risk. The study is limited to examining Swedish equity funds that have been active for at least ten years, between the years 2011-2020. The study adopts a quantitative research method, which aims to test theories. This research utilizes a regression and correlation analysis in conjunction with hypothesis testing, where variables are examined to provide a basis for the study's analysis of results. The results of this study show that Swedish equity funds on average underperform the Swedish market in the long term. The research also shows varying results regarding the correlation between risk-adjusted return and fee in the long term. The results of this study indicate that the Swedish capital market has a relative weak form of market efficiency. In addition, actively managed funds seem to be able to utilize occasional trend identification and information asymmetry to achieve an excess return. The research concludes that high-fee funds, which are more actively managed, indicate to be a better investment alternative for achieving long-term performance in comparison to passive funds.

Hållbarhet har kommit att bli en av denna generations största utmaningar och som ett resultat av ett globalt växande klimatfokus har regeringar och mellanstatliga organisationer utformat allt mer omfattande regleringar och initiativ för att möta samhällets krav på en hållbar utveckling. Att företag ska engagera sig i hållbarhetsarbete och ta socialt ansvar anses allt mer som en självklarhet och följaktligen har hållbarhetsfrågor inte enbart fått större inslag inom företag och dess ledningsgrupper, utan även hos investerare. Denna studie har som syfte att analysera huruvida ESG påverkar den justerade avkastningen på fonder i Sverige och Norden. För att analysera detta förhållande fokuserar studien på fonders hållbarhetsbetyg grundade på hållbarhetsparametrarna miljö, socialt ansvar och bolagsstyrning (ESG). I denna studie utforskar vi den övergripande frågan om konceptet ESG och för en diskussion kring dess inverkan på fondpriser. Metoden som används innefattar de finansiella kvoterna Sharpe, Sortino och Treynor samt Jensens Alfa, vars värden i sin tur jämfördes mot urvalet av fonder i studien som rangordnats efter Morningstars hållbarhetsbetyg. Studiens resultat leder till slutsatsen att det inte finns något tydligt positivt eller negativt samband mellan fonders riskjusterade avkastning och dess hållbarhetsbetyg. / Sustainability has become one of the biggest challenges for the current living generation and as a result of the increased focus on the climate issue, governments and intergovernmental organizations have designed increasingly comprehensive regulations and initiatives in order to meet society's demands for sustainable development. That companies should become more involved in sustainability work and take social responsibility is increasingly regarded as a matter of course, and consequently sustainability issues have not only gained greater importance within companies and its management groups, but also with investors. The purpose of this study is to analyse whether ESG affects the adjusted returns for funds in Sweden and the Nordics. In order to analyse this relationship the study focuses on the sustainability rating of mutual funds that are based on the sustainability parameters environmental, social and corporate governance, together referred to as ESG. In this study, we explore the overall concept of ESG and discuss its impact on fund prices. The method being used includes the financial quotas Sharpe, Sortino, Treynor and Jensen's Alpha, whose values in turn was compared against the selection of funds in the study ranked according to their respective Morningstar sustainability rating. The results of the study lead to the conclusion that there is no clear correlation, neither positive nor negative, between the funds risk-adjusted returns and its sustainability rating.

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.

This thesis studies the increasingly prevalent concept of sustainability in a financial context. Specifically, the question as to whether negative screening implies a cost or a benefit from an investor perspective is derived from past research’s inconclusive findings. The method adopted in order to answer the question is the construction of a negatively screened portfolio. The negative screening is done on an industry basis to see if excluding firms that engage in activities related to ESG risks would increase or decrease portfolio performance. Costs or benefits are primarily estimated as the intercept, also referred to as alpha, from Carhart’s (1997) four-factor model but is complemented by both the CAPM and the Fama-French three-factor model. The results of this study indicate no significant findings, as measured in alpha, achieved from the negative screening. However, the findings suggest a lower Sharpe ratio in the screened portfolio, and that negative screening may be associated with a lower systematic risk similar to what previous research has found.

The Covid-19 pandemic influenced the world with quarantines, travel bans, social distancing, and much more. Most remarkably, it brought the economy to a steep recession with changes in customer behavior and shocks to the financial markets. Combined with this, sustainable and green investing have grown in importance for firms that aim to incorporate sustainable practices in their businesses. This thesis evaluates the relationship between ESG and financial performance for Swedish issued mutual funds in the periods before, during, and after the covid pandemic. To capture the returns this study uses the Sharpe ratio, which penalizes volatility in the turns of funds and outputs risk-adjusted returns. The findings of this thesis highlight the importance of integrating non-financial metrics into portfolio management. The results found evidence that there is a difference in the performance between the two fund portfolios. Furthermore, this study will investigate the impact ESG variables have on the risk-adjusted rate of return. The results were that there is no compelling evidence of ESG variables impacting the returns. Moreover, significant insights from this study can be made to the Modern Portfolio Theory and Stakeholder Theory. By using Modern Portfolio Theory as the governing theory, a theoretical discussion has been made about the relationship between green investments and financial performance in times of sound economic markets and under financial crisis. This study is a quantitative study that has adopted the deduction approach. The authors of this thesis have retrieved 2 different portfolios, ESG and non-ESG, and compared the two groups against each other. 3 different periods have also been identified in the thesis: pre, during, and post Covid. The performance of the two portfolios has been examined during the three different stages to see how they have performed with hopes of finding empirical evidence that investing in ESG practices really is profitable. Statistical models such as OLS, heteroskedasticity, and more have been used in the study with the aim of helping the authors reach a conclusion.

Value investing as a strategy has a well-established history and has undergone extensive testing and studies within financial economics. Through the use of the strategy, studies and investors have demonstrated a positive return, where in many cases it has managed to generate excess returns compared to the market. The problem arises from the fact that the strategy should not be able to consistently generate excess returns compared to the market as it is not supported by the efficient market hypothesis (EMH). The purpose of the study is to investigate whether value investing as a strategy succeeds in generating excess returns on the Stockholm Stock Exchange. The method is based on a screening process, followed by a ranking system inspired by Joel Greenblatt’s value investment strategy "The Magic Formula". The method aims to systematically identify undervalued stocks based on the combination of two key ratios. Based on the applied method, two fictional portfolios were created with 15 stocks in each, based on value investing as a strategy. Historical data between 2013-2023 was collected to create the portfolios, with restructuring taking place each year based on set criteria. During this period, one of the portfolios showed a total return of 284.49%, which was an excess return compared to all benchmark indices in the study. The observed excess return suggests market inefficiency, where there may be opportunities for investors to identify and take advantage of undervalued stocks in the market. However, this excess return was not statistically significant when adjusted for risk, which in turn supports the EMH. Despite the strategy's success in generating excess returns compared to the market, it is therefore difficult to determine the level of efficiency at which the Swedish market has operated during the investigated period.

Socially responsible investing has presented itself as a growing, multifaceted, advanced and sophisticated investment philosophy. Socially responsible investment (SRI) involves incorporating social, ethical and responsible investment objectives with financial investment objectives during the investment decision-making process. Social, ethical and responsible investment objectives are set in line with environmental, social and corporate governance (ESG) criteria which are established within the SRI strategy followed. SRI strategies include screening (negative, positive and best-of-sector), shareholder activism and cause-based investing. Although international SRI markets such as that of the United States of America and the United Kingdom are sophisticated and established markets, the South African SRI market is still relatively new and is yet to reach its full potential. Thus, as a growing market, little research regarding the long term risk-adjusted performance of SRI funds in South Africa has been conducted. The long term risk-adjusted performance of the sample of SRI funds was measured through the use of five risk-adjusted performance measures, namely the Treynor ratio, Sharpe ratio, Jensen’s alpha, Sortino ratio and Omega ratio, and through the use of three performance measurement models which included the capital asset pricing model (CAPM), Fama-French three-factor model and Carhart four-factor model. The risk-adjusted performance of the sample of SRI funds was measured with the intent to establish if these funds out- or underperformed against three benchmark categories, namely the Financial Times Stock Exchange/Johannesburg Stock Exchange (FTSE/JSE) SRI Index, a matched sample of conventional investment (non-SRI) funds and the FTSE/JSE All Share Index. The probable effect of the 2007/08 global financial crisis was also measured to analyse whether such a hazardous market event affected the performance of the SRI funds. According to the results and findings, the risk-adjusted performance of the SRI funds has improved over the research period. However, the SRI funds neither outperformed nor underperformed against the three benchmark categories over the research period. The performance measurement models’ analysis indicated that the SRI funds were less sensitive to market fluctuations, more exposed to small capitalisation portfolios, more growth-oriented, and exhibited significant momentum after the period of the 2007/08 global financial crisis. Furthermore, the analysis indicated that the SRI funds significantly underperformed against the non-SRI funds during the Performance of socially responsible investment funds in South Africa research period. Mixed results were obtained with regards to the probable effect of the 2007/08 global financial crisis on the performance of the SRI funds.

Previous research has confirmed the existence of a value premium in a wide array of markets and using this value stock anomaly has yielded superior performance. This thesis investigates if one could take advantage of the existence of a value premium to deploy a dynamic investment strategy on the Swedish stock market (OMXS30) with focus on minimizing risk to achieve higher risk adjusted performance than the stock market index. The investment strategy implemented use Market-to-Book-Value to screen for both entry and exit signals and Modern Portfolio Theory, using the minimum-variance portfolio with short-selling constraints, to allocate assets within the portfolio. The investment strategy is evaluated using the Modigliani-Modigliani Risk Adjusted Performance measure. Conclusions from the thesis are that the strategy does outperform the Swedish stock market index, both in terms of nominal return and risk-adjusted performance. The suboptimal behaviour of investors where they overreact  to signals and unconsciously rely on heuristics is used to explain why this is possible. Market-to-Book-Value, using the first quartile as entry signal and third quartile as exit signal, is considered to be a successful key ratio to screen for value stocks.

Background: In 1999 the Swedish pension system was reformed with an aim to create a stable and high return on pension assets. First, Second, Third and Fourth general pension funds, hereby referred to as AP1-AP4, had an important part in the reform. AP1-AP4, also called the buffer funds, was assigned to secure long-term, big parts of the pension capital. The funds objective is by law, to manage the fund's assets in a manner that provides maximum benefit for the state pension. The funds will also invest pension assets with an overall low level of risk while achieving a sustainable high return. Aim: The purpose of this study is to investigate whether the First-Fourth AP-Funds is meeting its objectives regarding risk and return according to Swedish law. The aim is also to see how AP1-AP4 risk-adjusted returns compare to the four Sweden funds risk-adjusted returns according to modern portfolio theory. Theory: Morningstar Rating, Treynor ratio, Sharpe ratio, Jensen's Alpha, Standard Deviation, Beta. Conclusion: The risk-adjusted performance measures used in this study shows that there are clear differences between the two fund groups, where the AP-funds performed worse than the Sweden funds in every measurement. The study shows that the pension funds do not reach their goals over the five-year period, in four of the five time intervals listed in the study. In summary, the study shows that pension funds have a lower risk-adjusted return than the four bank Sweden funds and that the pension funds have not achieved their goals.
