[pt] Este trabalho analisou o desempenho de 31 fundos mútuos comportamentais atuantes nos EUA, Europa e Japão descritos em Santoni e Kelshiker (2010). Foram observados os desempenhos dos fundos e seus respectivos Benchmarks em quatro indicadores: Índice de Sharpe, Índice de Sortino, Medida Ômega e Medida de Desempenho Comportamental. O horizonte da análise foi de 10 anos (jan/04 a dez/14) dividido em intervalos de 6, 12, 36, 60 e 120 meses. A partir da consolidação dos indicadores os fundos foram ranqueados e classificados em três faixas de desempenho: superior, intermediário e inferior. No intervalo de 120 meses não houve, na média geral, diferença de desempenho significativa (a 5 por cento) entre os fundos e os Benchmarks. A análise por intervalos indicou que o desempenho dos fundos em relação aos Benchmarks piora conforme aumenta o prazo de aplicação. Nos intervalos mais curtos (6 e 12 meses) não houve, na média, diferença de desempenho significativa enquanto nos prazos mais longos (36 e 60 meses) o desempenho médio dos fundos foi significativamente inferior aos Benchmarks. Na média de todos os intervalos o desempenho médio dos fundos foi significativamente inferior aos Benchmarks. Dentre os indicadores utilizados, o índice de Sortino foi o que apresentou maior correlação com o desempenho geral dos fundos. / [en] This work has analyzed the performance of 31 behavioral mutual funds operating in USA, Europe and Japan, as described in Santoni and Kelshiker (2010). It has been observed the performance of the funds and their respective Benchmarks according to four measures: Sharpe Index, Sortino Index, Omega Measure and Behavioral Performance Measure. The analysis covered a 10-year period (jan-04 to dec-14) split into intervals of 6, 12, 36, 60 and 120 months. Based on the consolidation of the performance measures, the funds have been ranked and classified into three performance categories: upper, intermediate and lower. In the 120-month interval there has not been, on average, a significant difference (at 5 per cent) in performance between funds and Benchmarks. The analysis by intervals showed that the funds performance worsens in relation to the Benchmarks as the investment period increases. In shorter intervals (6 and 12 months) there has not been, on average, a significant difference in performance while in the longer intervals (36 and 60 months) the funds average performance was significantly lower than the Benchmarks. Computing the mean of all intervals, the funds average performance was significantly lower than the Benchmarks. Among the performance measures used, the Sortino Index presented the highest correlation with the general performance of the funds.

In december 2019, the first cases of covid-19 were reported in Wuhan, China. Since then, the virus has spread rapidly around the world. In order to try to stop the spread of the virus, isolation has become actual. Except affecting the public health, the virus has caused deep traces in the global economy. A clear stock market fall on the Swedish stock exchange could be observed in February-March 2020. The financial crisis that has arisen is the first crisis many of the young investors, of the age 18–30 years old have to manage. Due to the economic crisis that has arisen, this study aimed to describe young investors' decision-making in the financial market during the period 1 January 2020 to 5 May 2020. The research question goes as follows: What factors influence young investors' decision-making in the financial market during an economic crisis? The study was conducted on the basis of the Theory of Behavioral Finance. This theory assumes that the individual's decision-making in the financial market is largely influenced by emotions and other psychological factors. Furthermore, the theory is based on a number of different assumptions about human psychological and behavioral phenomena that influence investment decisions. The procedure for conducting the study was to make a descriptive quantitative study. This meant that a questionnaire was passed on to young investors and that the answers were then compiled in diagrams and tables. The results indicated that the factors overconfidence, representativeness bias and anchoring bias seemed most likely to describe young investors' decision-making in the financial market during an economic crisis. At the same time, a reasonable interpretation seemed to be that herding behavior and risk and loss aversion cannot describe the young investors' decision-making to a large extent. The importance of mental accounting could not be determined in this context, as the answers received provided an incomplete basis for deciding this. To be able to draw conclusions about the role of mental accounting in decision-making, several issues that dealt with this would have been useful. One suggestion for continued research is to study other factors that may underlie young investors' decision-making during an economic crisis.

Genom att använda ett stort urval av riktkurser utgivna på företag inom OMXS30 under åren 2010–2019, undersöker vi huruvida riktkursförändringar ger upphov till en marknadseffekt eller inte. Med hjälp av en eventstudie visar vi på en signifikant riskjusterad avkastning dagarna omkring förändringen i riktkursen. Genom att dela in riktkursförändringarna i kvintiler, visar studien att graden av riskjusteradavkastning dessutom är hänförbart till dels hur pass stor riktkursförändringen är, dels om den är att beakta som positiv eller negativ. Dessa resultat är särskilt starka när förändringen i riktkursen är ställd mot den tidigare riktkursen av samma analyshus, snarare än när den är ställd mot rådande aktiekurs. Därtill genomförs en regressionsanalys vars resultat stödjer ett positivt samband mellan riktkursförändring och riskjusterad avkastning. Slutligen medför studien ny relevant information om kvartalsrapporters effekt när det kommer till studier om riktkursförändringar. Till skillnad från den tidigare forskningen, eliminerar vi riktkurser som sammanfaller med kvartalsrapporter och visar på skillnader i den riskjusterade avkastningen som följer. / By using a large dataset of target prices issued on companies included in the OMXS30 index during the years 2010-2019, we examine whether target prices cause a short-term market reaction. By doing this, we take an event-study approach and find a significant abnormal return around the days the target price is published. By categorizing the change in target prices into different quintiles, we also show that the size of the abnormal return is due to the change in the target price and whether it’s considered positive or negative. These results are especially salient when the change in target price is based on the earlier target price from the same firm rather than the current stock price. In addition to the event-study a regression analysis is performed, which supports the positive association between the target price change and the abnormal return. This paper also provides useful information about the effects from quarterly reports in prior studies. Unlike previous research, we exclude all target prices that coincide with quarterly reports and find differences in the abnormal return that follows.

This thesis contributes to the currently still sprawling literature on the force of sustainable investing together with the “Big Five” personality structure (Openness to Experience, Conscientiousness, Extraversion, Agreeableness and Neuroticism). By investigating which personality trait, based on the Big Five personality taxonomy, that was willing to exchange revenue for a higher ESG rating in a hypothetical investment fund, we were able to determine when private investors were willing to pay more for a more sustainable investment. We use new data from our own questionnaire where the respondents are adult individuals residing in Sweden who has invested in the stock market. The data was analyzed with an econometric approach and for the regression ordinary least square and tobit was used. The results revealed that two personality traits (conscientiousness and agreeableness) tended to be less interested in sustainable investments, as they were not willing to pay for a fund with a higher ESG rating, unlike Openness to Experience, where the willingness to pay was high. The other two traits also showed a positive relationship and thus willingness to trade revenue for sustainability. This thesis contributes to the knowledge on how the personality of the private investors can motivate investment decisions and the preference of companies they invest in.

The aim of the thesis is to afford a complex perspective of a parallel development of psychology and economics to the readers. It is suggested, how psychological experiments could be used for the overall enrichment of the classical theory of economics. In the thesis, readers are introduced to the development of economic theories over time, and also to what role a human takes as a personality. Including the thesis is the part engaging in consumer decision process.

This study has examined the ten most shorted shares belonging to the Swedish Stockholm Stock Exchange's Large Cap list, by following randomly selected financial institutions that have chosen to take short positions. The purpose of the study is to investigate whether it is possible for short sellers to generate an excess return compared to the index OMXS30GI. The theory is mostly about short selling in general, efficient market hypothesis, behavioral finance, opponents of short selling, technical analysis of an index and the theory also includes previous research regarding short selling. The method used is based on collected secondary data from different databases. Via the secondary data, we have artificially followed randomly selected financial institutions that have glossed over and done the same as them to see if it can generate an excess return. In this study we will not take the cost associated with short selling into account which normally would be costs as margin interest, stock borrowing costs and commissions to brokers. The results show that it is possible for short sellers to generate an excess return that outperforms index OMXS30GI. We can also conclude that short sellers follow a pattern that indicates that they do not act in a way to destroy market efficiency and we can question whether the market is efficient or not.

This study highlights the structures and networks thatexist among financial analysts on the Swedish financial market. The study isbased on nine semi-structured interviews with buy- and sell-side analysts, anindependent analyst and an Investor Relations Manager. The theoretical framework of the study is based on acombination of the research fields Behavioral Finance and Social Studies ofFinance. These two research fields have proven to be a good basis for thequalitative approach used in the analysis. The study is divided into four thematic areas: Fundamentals / Psychology, Independence and consensus, Ranking and Social network. The results show that there are a large number offactors, structures and interpersonal relationships that affect how analystsmake their decisions and conduct their analysis. Among other things, theinterdependence between analysts and their counterparts prohibits the movetowards a more clear system for compensation. These structures can also have animpact on analysts' rationality from an individual perspective and a network perspective. Furthermore, we have found that technological developments willpose major challenges for the sell side's ability to generate revenues in the future. / Denna studie belyser de strukturer och nätverk som förekommer bland aktieanalytiker på den svenska finansmarknaden. Studien baseras på nio semi-strukturerade intervjuer av aktieanalytiker på köp- och säljsidan, en fristående analytiker samt en IR-ansvarig. Den teoretiska referensramen som studien baserar sig på är en kombination av forskningsfälten Behavioral Finance och Social Studies of Finance. Dessa två forskningsfält har visat sig utgöra en bra grund för den kvalitativa ansats som använts i analysen. Studien är uppdelad i fyra tematiska områden: Fundamenta/Psykologi, Självständighet under konsensus, Ranking och Nätverk. Resultaten visar att det finns ett stort antal faktorer, strukturer och interpersonella relationer som påverkar hur analytiker fattar sina beslut och genomför sina analyser. Bland annat innebär de ömsesidiga beroendena mellan analytikerna och deras motparter att en utveckling mot ett mer tydligt ersättningssystem förhindras. Dessa strukturer kan även ha en påverkan på analytikernas rationalitet ur ett individ- och nätverksperspektiv. Vidare har vi funnit att den tekniska utvecklingen kommer innebära stora utmaningar för säljsidans förmåga att generera intäkter i framtiden.

An individual's behavior is a substantial part of one’s personality and is a big part in decision-making, it applies to large and small decisions in our everyday lives. An increase in the proportion of young adults in the stock market has been observed in recent years. Our world was hit by a pandemic, Covid-19 and as a result of this pandemic, a majority of countries in the world experienced financial crises and difficulties. Many analysts noticed, however, the continued increase in private investors in the stock market. The results in this study have shown that an individual's personality and personal traits are decisive factors in how an investor will behave in the stock market. The different causes and factors addressed in the study affect each respondent in different ways where some were affected more and others less. The study thus showed that it was not only one factor or cause that affects how risky an investor is, it is a combination of several factors and causes. This study has provided a new perspective for the theorists as the study took place during a pandemic. Lastly, this study has given rise to relevant questions that are presented in future research suggestions. / En individs beteende är en stor del av personligheten och är även en avgörande faktor för olika beslut som vi individer fattar, det gäller såväl stora som små beslut i vår vardag. Olika faktorer och orsaker har större påverkan i vårt beteende än vad vi kan tro, även i vårt köpbeteende på finansmarknaden när investerare tar beslut om diverse investeringar såsom aktier. Det har i synnerhet observerats en ökning av andelen unga vuxna på aktiemarknaden under de senaste åren. Vår värld drabbades av en pandemi, Covid-19 och till följd av denna pandemi upplevde majoriteten av världens länder finansiella kriser och svårigheter. Det intressanta som däremot många analytiker uppmärksammade var den fortsatta ökningen av privata investerare på aktiemarknaden, speciellt de unga vuxna. I och med den ännu pågående pandemin har det därmed inte gjorts studier och observationer om privata investerares köpbeteende under just Coronapandemin. Detta har gett upphov till att föra en kvalitativ studie om vilka orsaker och faktorer som påverkar privata investerares köpbeteende och hur pass riskaverta investerarna är baserat på dessa orsaker och faktorer och det individuella köpbeteendet. Med hjälp av teorier och tidigare forskning från området beteendeekonomi (”behavioral finance” på engelska) har denna studie, vars avsikt varit att undersöka köpbeteende och grad av riskaversion, varit möjlig. Resultaten har visat att en individs personlighet och de personliga dragen är avgörande faktorer för hur en investerare kommer att bete sig på aktiemarknaden. De olika orsakerna och faktorerna som togs upp i studien påverkar varje respondent på olika sätt där vissa påverkades mer och andra mindre. Graden av riskaversionen hos studiens respondenter gick att avgöra baserat på varje investerares övertro på sig själv, hur påverkade de blir av lättillgänglig information, stereotyper som ett företag kan påvisa samt flockbeteende. Studien visade därmed att det inte endast var en faktor eller orsak som påverkar hur pass riskavert en investerare är, det handlar om en blandning av flera faktorer och orsaker. För just denna åldersgruppen var graden av riskaversion av svagare karaktär vilket indikerar på att investerare i denna åldersgrupp inte är rädda för större risker. Denna studie har gett ett nytt perspektiv för teoretikerna då studien tagit plats under en pandemi vilket kan ha bidragit med andra resultat med tanke på den finansiella krisen som världen drabbades av. Avslutningsvis har denna studie gett upphov till relevanta frågor som presenteras under förslag på framtida forskning.

We find that the first investment of a private investor in an IPO affects the private investors future participation in IPO’s. This paper examines Nasdaq Stockholms Main list during 2010-2019. The short- and long-term perspective is examined by two different models. The results show that there is a significant difference between private investors when it comes to participating in future IPO’s, depending on if the private investor experienced a good or bad IPO. The result in this paper show that approximately a third more private investors participate in the upcoming IPO after they experienced a good IPO. In a longer perspective approximately 50% of the investors who experienced a good IPO choose to invest in at least one more IPO.  Out of the private investors who experienced a bad IPO, approximately 30% choose to participate in another IPO. This paper contribute to a better understanding of how private investors are affected by their earlier investments.

The prospect of earning extraordinary returns drives the allure of investing in new companies through IPOs. However, this approach may be flawed due to market conditions, information asymmetry, and behavioral biases. Past research supports evidence of the long-term underperformance of IPOs compared to the market index. Despite the substantial research on IPO performance, limited studies have focused on the long-term performance of IPOs in Sweden and among industries, particularly from 2010 to 2019. The study aims to address the existing knowledge gap and provide investors with insights into the long-term performance of Swedish IPOs and their associated industries. By analyzing IPOs, the study enhances the risk-reward understanding, informs retail investment decisions, and promotes stock market transparency in Sweden. The research employed a quantitative method with a deductive approach. Stock prices 12 and 36 months after the IPO date and prospect prices were collected as the data set. The data were analyzed using statistical applications to assess the significance of the research findings, employing a One-Sample T-test and Kruskal-Wallis H-test. The findings indicate that the IPOs in our sample underperformed the selected index, OMXSGI, with an average underperformance of 7.84% for 12 months and 12.32% for 36 months. The results are in line with previous research of similar markets as Sweden. Additionally, performance varied among industries, with the technology sector performing the best and consumer staples performing the worst.
