Background: As the goal of most investors is to generate excess returns as compared tothe broad market, different investment strategies to perform such a feat have been studied thoroughly for decades. One strategy which has performed particularly well is the value investment strategy, where securities that appear cheap relative to some of their fundamental values are invested in. More recently, the growth investment strategy, where securities are instead bought if some of their fundamental values are expected to rise rapidly in the future, has caught more attention from investors. As the efficient market hypothesis suggests that no investment strategy should be able to consistently generate excess returns without any luck involved, it is of interest to examine whether the aforementioned strategies act in congruence with the hypothesis. Purpose: The purpose of this study is to analyze if the value and growth investment strategies generate superior returns as well as risk-adjusted excess returns when compared to the Swedish stock market. The study also aims to analyze how the performance of the strategies varies during periods of different market sentiments. Methodology: This study used a quantitative method in its data collection and was conducted using a deductive approach. Six synthetic portfolios were created to test the strategies’ performance. The stocks which constituted the synthetic portfolios were chosen based on their P/E and P/B values from the Refinitiv Eikon platform, and the portfolios were rebalanced annually over the entire analyzed time period. The Swedish All-Share index, OMXSGI, was used as a proxy for the market portfolio. Conclusion: Based on the results of the study, the growth portfolios, more so than the value portfolios, were found to generate greater statistically significant returns as compared to the broad market during the analyzed time period. Although not all portfolios generated excess returns, the study may still add to the evidence that disproves the efficient market hypothesis.

This paper aims to analyze the phenomenon of adverse selection of its presence and potential short-term impact on the Swedish stock market. Adverse selection refers to a situation where information asymmetry among market participants might lead to potential imbalances in information and unfairness among all market participants. The primary objective of this paper is to determine and analyze the potential existence of adverse selection and to explore its effects on the short-term trading volume before announcements.  This study's research design and approach are through data collection, to analyze the relationship between traded volume and disclosures. Five highly traded stocks, Atlas Copco AB, Evolution AB, Swedbank AB, Hexagon AB and AB Volvo are selected for the analysis, representing different sectors. A historical data analysis method and event studies are being used to identify abnormal fluctuations in trading volume before announcements. Data on volume and stock prices are collected over one year, between 11 May 2022 - 11 May 2023. By utilizing various statistical methods and econometric techniques, abnormal volume fluctuations before announcements could be measured and analyzed.  This paper concludes the existence of short-term adverse selection on the Swedish stock market cannot confidently be determined considering this analysis only, as indicated by nonsignificant abnormal fluctuations in the short-term trading volume before announcements. However, the results of the data collection in the period between 11 May 2022 - 11 May 2023, on five high-market capitalization companies, still emphasize and illuminate the importance of ensuring and maintaining efficient and fair markets.

This thesis investigates pricing-performance of two recently developed multifactor asset-pricing models with the implementation of dual-betas dependent upon prevailing market-conditions. The models included in the study are the Fama and French five-factor model and the Q-factor model by Hou, Xue and Zhang. We test the models on cross-sectional Swedish stock-market data between 2003 and 2015 from the Large-, Mid- and Small Cap-lists and their respective precursors. The models are tested in their ability to explain portfolios sorted on firm beta-values, on a twelve-year period as well as a six-year period characterized by changing market directions and high market volatility.  In our study, we support the presence of changing risk-return relationship in up and down market states by estimating separate market betas with the risk-free rate as threshold. However, we do not find the isolated and volatile period to give rise to a larger difference in the up and down market betas. We consistently find the models to have a decreasing explanatory power on the portfolios of firms with lower beta values. We also find the largest difference in the up and down market betas occurring in the low beta portfolios, suggesting that this is causing measurement problems in the models. While making the models conditional, the measurement problem with the static beta seems to be reduced for the portfolios where the difference between up and down betas differ most. In the applied context, we conclude the conditional dual beta adds explanatory power in the models when the market beta differs in up and down market states.  The insights of this thesis support the method of making the market-beta conditional as suggested by Pettengill, Sundaram & Mathur (Pettengill, et al., 1995), in new multifactor models.

This essay will compare the capital asset pricing model (CAPM), Fama and French threefactor model and Carhart´s four-factor model, to see which of these models that can explain portfolio excess returns best on the Swedish stock market. This thesis will tempt to validate the three and four-factor models because of the limited amount of research done on the Swedish stock market. The results indicate that the three-factor model improves explanatory power for portfolio returns in comparison to the CAPM, and the four-factor model gives a small improvement in the explanatory power compared to the three-factor model. The results also indicate that all models have a low explanatory power when the market is volatile.

This paper investigates the signaling effect of insider trading by analyzing the market reaction to 147 insider transactions executed within the period 2014-2016 on the Stockholm Stock Exchange. We present three major findings. First, we find significant market reactions for both insider purchases and insider sales, suggesting a signaling effect of insider trading. Second, we find the signaling effect to be similar for both insider purchases and insider sales. Third, we find that firm size has an influence on the signaling effect. Our findings indicate that the market values information about insider trading and that firm size has an effect on this informative value. / Denna studie undersöker signaleringseffekten av insynshandel genom att analysera marknadsreaktionen för 147 insynstransaktioner utförda under perioden 2014-2016 på Stockholmsbörsen. Vi presenterar tre huvudsakliga upptäckter. Den första är att vi finner en signifikant marknadsreaktion för både köptransaktioner och säljtransaktioner utförda av insynspersoner vilket indikerar att det finns en signaleringseffekt av insynshandel. För det andra finner vi att signaleringseffekten är lika stark för både köptransaktioner och säljtransaktioner. För det tredje finner vi att bolagsstorlek har en påverkan på signaleringseffekten. Dessa upptäckter visar på att marknaden ser ett värde i information om insynshandel och att bolagsstorlek påverkar detta informationsvärde.

Investors and fund managers have, since the start of financial markets, always been on the lookout for new ways of beating the market. However, researchers of the Efficient Market Hypothesis have shown that markets are usually highly efficient, implying that there are few possibilities of earning returns that are higher than the market returns, on a risk adjusted basis. Prevailing theories, such as the Capital Asset Pricing Model, has shown that increased return must stem from taking on higher risk. Though, this model’s explanatory power has been challenged by numerous researchers who propose different factors, other than market risk, which could hold explanatory power when it comes to returns in the stock market. This area of research is called factor investing, and has shown that factors such as momentum, size, and value, all can lead to outperforming the market.This study examines how a model based on two common factors, quality and value, would have performed on the Swedish stock market. The study is based on five portfolios chosen by the quality and value factors, each one held for 5 years, examined over a 25-year time span and uses the capital asset pricing model as a tool to measure whether or not the selected factors outperform the market. The study has taken a quantitative approach to examining the research question, using a positivistic and objectivistic view.The results of the study show evidence that the quality and value factors can lead to significant outperformance relative to the market index. Both total returns and risk adjusted returns were higher than the market index for some of the portfolios created using the quality and value factors. Furthermore, statistical evidence was found of that CAPM not fully explains all returns, and thus, that the returns are in part explained by the quality and value factors. The findings led to the conclusion that the quality and value factors does, in fact, hold explanatory power beyond that of CAPM. Purchasing quality companies at a reasonable price is shown to be a sound investment strategy, and that a portfolio created using the quality and value factors has good chances of outperforming the market index.

Tidigare studier i USA har påvisat ett positivt samband mellan individuella investerare som köper lotter och deras benägenhet att köpa aktier med liknande karaktärsdrag. Enligt klassisk finansteori bör inte individuella investerare äga så kallade lotteriaktier då de tenderar att generera negativ avkastning – trots detta äger många individuella investerare lotteriaktier. I denna studie undersöker vi om detta samband kan förklaras med hjälp av socioekonomiska faktorer som arbetslöshet, utbildningsnivå och spelutgifter på länsnivå. Studien behandlar uteslutande svenska data för socioekonomiska faktorer som utgörs av Sveriges befolkning, aktiedata som utgörs av dagliga stängningspriser för samtliga marknadsnoterade aktiebolag, och aktieägardata för samtliga marknadsnoterade aktiebolag som utgörs av svenska individuella investerare. Vidare är samtliga data insamlade från legitima datakällor för perioden 2012–2015. För att möjliggöra undersökandet av vilka individer som äger lotteriaktier väljer vi att definiera lotteriaktier i enlighet med tidigare studier, där lotteriaktier definieras som aktier med lågt pris, hög idiosynkratisk volatilitet och hög idiosynkratisk skevhet. Dessa egenskaper har visat sig attrahera riskbenägna investerare trots sin låga sannolikhet till hög vinst. Studien utgår från teorier inom behavioral finance där individers irrationella beslutsfattanden belyses. Teorier som prospect theory och cumulative prospect theory förklarar hur individer värderar vinster och förluster olika, samt hur individer tenderar att överskatta små sannolikheter och underskatta stora sannolikheter. Dessa teorier skapar ökad förståelse för varför individer agerar som de gör vid beslutsfattanden på finansiella marknader. Dessa teorier ställs i kontrast mot klassiska finansteorier som förutsätter att individer är rationella, kalkylerande och inte påverkas av irrationellt beteende eller känslor. Studiens resultat visar att i de län där antingen spelutgifter per capita är höga eller spelutgifter per nettoinkomst är höga är även andelen lotteriaktier hög, vilket överensstämmer med tidigare forskning i USA. Det visar sig även att antalet lotteriaktieägare och deras portföljexponering mot lotteriaktier ökar kraftigt under perioden, samtidigt som antal aktieägare i Sverige hålls relativt konstant under perioden, vilket indikerar ökande irrationalitet bland svenska individuella investerare på svenska finansiella marknader. / In this thesis, we examine individual investors preferences for lottery-type stocks between January 2012 and December 2015. Lottery-type stocks have shown to have similar characteristics to state lotteries through its low price, high idiosyncratic volatility and high idiosyncratic skewness in previous studies. These characteristics attract risk-seeking investors who aim for a small chance to win big. In detail, we analyze if there is a relationship between socioeconomic factors like unemployment rate, education, gambling expenditures per capita, gambling expenditures per net income and the propensity to hold lottery-type stocks in the individual stock portfolio in Sweden. The analysis is based on aggregated data of Swedish counties and the study is unique in regard to the Swedish stock market. Our results show that there is a positive significant relationship between gambling expenditures per capita, gambling expenditures per net income and a higher proportion of lottery-type stocks in the individuals stock portfolio within a county. These results show that socioeconomic factors that induce greater expenditures in lotteries are associated with greater investments in lottery-type stocks. Finally, our findings contradict the efficient market hypothesis and could thus be a contribution to the field of behavioral finance.

Syfte: Tidigare forskning visar på en positiv abnormal avkastning på företagets aktiekurs vid återköp av aktier. Få studier har vidare undersökt om denna avkastning skiljer sig beroende på frekvensen av återköp. Området kring återköp av aktier är relativt outforskat i Sverige och sedan återköp blev tillåtet år 2000 har det varit en finanskris. Denna studie syftar därmed till att fylla ut forskningsgapet i Sverige med att studera återköp och dess påverkan på avkastningen på den svenska aktiemarknaden, med hänsyn till återköpsfrekvens. Studien är avgränsad till lågkonjunkturen mellan åren 2010-2014 för att se eventuell skillnad från tiden före finanskrisen. Metod: För att besvara studiens syfte har en eventstudie genomförts. Aktiekursdata för de företag som genomfört återköpsprogram under de studerade åren har samlats in från Nasdaq OMX Stockholm. Av dessa aktiekursdata har kumulativ abnormal avkastning beräknats för att jämföras mellan grupper och andra studier samt genomföra t-test och envägs-ANOVA. Studiens data består av 68 återköpsprogram fördelat på 41 företag som har delats in i frekvensbaserade grupper på ”1”, ”2-3” och ”4-5” stycken återköpsprogram. Resultat & slutsats: Studiens resultat stödjer den tidigare forskningen om att återköp ger en positiv abnormal avkastning. Resultatet stödjer även signaleringsteorin om att återköp signalerar undervärdering vilket leder till att investerare pressar upp aktiepriset. Resultatet visar däremot inget stöd till de studier som har visat på att återköpsfrekvensen ska ha betydelse för avkastningen eller att avkastningen skulle ha varit högre under lågkonjunktur. På grund av få och motsägande forskning kring detta behövs det mer forskning som kan förtydliga frekvensen och lågkonjunkturens påverkan på avkastningen. Examensarbetets bidrag: Det är intressant ur företagsekonomisk synpunkt att se vilken effekt återköp får på aktiepriset när företag funderar på att utnyttja bemyndigande om återköpsprogram. Denna studie visar att företag i Sverige kan förvänta sig en positiv abnormal avkastning vid annonsering av ett återköpsprogram, i likhet med andra miljöer. Studien visar även att frekvensens och lågkonjunkturens betydelse fortfarande är oviss. Förslag till fortsatt forskning: Eftersom studien endast har undersökt den kortsiktiga avkastningen vid återköp av aktier vore mer forskning kring den långsiktiga avkastningen intressant. Studien har inte heller studerat egenskaper hos företagen som gör återköp. Eventuella skillnader mellan företag som gör enstaka respektive frekventa återköp vore intressant att se. / Aim: Previous research has indicated that share repurchases result in a positive abnormal return on company's share price but only a few studies have examined further if return on share price differs depending on frequency of share repurchases. In Sweden share repurchases are quite unresearched field of study and after share repurchases became legal in 2000 there has been a financial crisis. This study aims to fulfil the research gap in Sweden and examine share repurchases' effect to return on share prices depending on frequency of share repurchase on Swedish stock market. Time period of the study has narrowed down to recession between years 2010-2014 to see eventual difference from time before recession. Method: To fulfil the aim of the study event study methodology has been used. The share data for companies that have repurchased shares in chosen time period has been collected from Nasdaq OMX Stockholm. Based on share data cumulative abnormal returns for every share repurchase group have been calculated to compare groups and different time periods. Cumulative abnormal returns are even used to accomplish t-test and one-way ANOVA. Data of the study consist of 68 share repurchase programs that were announced by 41 companies. Those 68 repurchase programs were distributed to three frequency based groups that were ”1”, ”2-3” and ”4-5” share repurchase programs. Result & Conclusions: Results of the study are consistent with the previous research about share repurchases resulting in a positive abnormal return. The results are also consistent with the previous research about repurchases signaling an undervalued stock which leads to an increase in interests from the investors. On the contrary this study is not consistent with the previous research about repurchase frequency and recession's impact to return. Because there are only a few studies about repurchasing frequency and recession's impact to return and the results of studies are contradictory, more research needs to be done. Contribution of the thesis: It is interesting to see which kind of effect share repurchases result in share price when company is utilizing authorization of share repurchase program. This study indicates that a company in Sweden can predict a positive abnormal return by announcing about repurchase program. The study indicates even that repurchase frequency and recession's impact to return are still uncertain. Suggestions for future research: As this study has only examined share repurchases' short-term effect to return on share price, it would be interesting to research long-term effect to return on share price. Also characteristics of companies that repurchase shares and eventual differences between companies that repurchase shares frequent and infrequent would be interesting to see.

This thesis examines the performance of portfolios sorted by gross-profit-to-asset (GPA) as a quality investing on the Swedish stock exchange. It constructs long-only portfolios and long-short portfolios sorted by GPA, book-to-market (B/P) and earnings-per-price (E/P). Thus, the thesis includes quality and value investing. The thesis compares separately the constructed long-only and long-short portfolios among each other. The long-only strategies are additionally compared to the market index. The study further examines a combined portfolio, sorting for GPA and B/P in order to test Novy-Marx’s findings. He reports, that the average return improves, while the standard deviation remains at the same level for a combined portfolio sorting for GPA and B/P. This requires a negative correlation. The comparison is based on different portfolio measurements as i.e. s.d. The asset pricing models CAPM and 5-Factor Model are applied. In addition, actual returns, excessive return over the risk-free rate and over the market index as a benchmark are assessed for the portfolio. The analysis is conducted for the time period 1994-2013 and separately for downturns, considering 2000-2003, 2007-2009 and 2010. The results show a great applicability of the gross-profitability ratio on the Swedish market. This quality strategy convinces not only during normal times with the portfolios GPA-h (long-only) and GPA-hl (long-short) but also in stressed times. GPA-h reports positive (abnormal) returns GPA-h during downturns. The long-only and long-short portfolios based on GPA outperform the market in both time periods. GPA-sorted portfolios perform in general better and the two value strategies during normal times and downturns, based on the annual average return. Examining the two value strategies EP-sorted portfolios are superior over BP-sorted portfolios. EP-portfolios achieve better performance during downturns, regarding Jensen’s alpha. It can be derived, that EP is countercyclical. The combined portfolio generates high return and has a high standard deviation. The assessed statement of Novy-Marx cannot be confirmed for the Swedish stock market. It has to be stated that we detected positive correlation instead of negative correlation. It can be derived, that GPA ratio is applicable on the Swedish market, considering the assumptions and limitations of this study. EP-based portfolios show a good performance during downturns. BP- based portfolios do not perform well on the sweidish market in the assessed time frame. The combined portfolio GPABP-hh does increase returns with constant standard deviation, referred to BP-h. Our findings show, that both value strategies do not outperform the market index. The EP-based value portfolios outperform BP-based portfolios. EP-h performs better during downturns considering Jensen’s alpha.
