Problem: How can segments on Aktietorget explain how a lemon market can not only survive but grow? Purpose: The purpose is to try to explain how Aktietorget can grow under lemon market conditions by gauging investor groupings investment tendencies. Method: Quantitative archival study regarding returns and price per share depending on investor identity. Conclusion: Finance industry investor yields higher returns, which implicates the possibility of rational investing. This is attributed to either identity inherited capabilities or them being agents in the place of the principal. The private investor on the other hand is full principals and has a tendency towards low price per share. All other capital on Aktietorget conforms to the lottery characteristics of Aktietorget.

This paper presents an investigation into the relationship between the announcement of acquisitions, the existence of positive abnormal return for shares of these firms and market efficiency in Germany, France and Great Britain. The sample of transactions ranged from January 2010 to December 2015. This thesis has used the event study methodology where the Cumulative Average Abnormal Returns (CAAR) of the target and bidder firm's stock prices in different event windows have been analysed. Across all the markets, target firm's stock price yields positive CAAR that is significantly different from zero on the day of the announcement. Unlike the target firms, bidder firms do not show statistically significant CAAR for all analysed markets. The second goal was to analyse market efficiency using CAAR data from the event study. It was concluded that the analysed markets behave in a semi-strong form of market efficiency with potential cases of insider trading identified.

This paper initially presents the theory behind technical analysis and the conditions for using it. Then it describes how the test of indicators was made. Then the results are commented upon by various titles, markets and indicators. After evaluating the success of technical analysis on various markets, this success was compared between the markets what led to determination of the markets efficiencies.

En god inblick i den ekonomiska marknaden leder till ett gynnsamt läge från vilket vi kan maximera avkastningen på våra investeringar. Är det möjligt att genomföra en sådan typ av investering sett till endast bolagens storlek? Ett flertal studier har genomförts kring småbolagseffekten som en anomali på kapitalmarknaden. Effekten innebär att småbolag skulle generera en högre procentuell avkastning än storbolag under samma tidsperiod, vilket inte går i linje med vad den effektiva marknadshypotesen påstår kring kapitalmarknaden. Avsikten med denna undersökning är att analysera huruvida detta stämmer eller ej. Syftet med studien är att analysera om det förekommer en mikrobolagseffekt på den svenska aktiemarknaden under åren 2005-2014, det vill säga en anomali med extremare utfall av småbolagseffekten. Vi har använt oss av en kvantitativ statistisk analys för att mäta de genomsnittliga avkastningarna mellan de tre olika portföljer vi skapat bestående av bolag från Large Cap, Small Cap och Aktietorget. Tre hypoteser är testade och resultatet är analyserat med hjälp utav ett statistiskt t-test i programmet SPSS. Studiens resultat är att det inte går att påvisa någon signifikant skillnad i avkastningen mellan storbolag, småbolag och mikrobolag under den givna tidsperioden. Inte heller under delperioder har det kunnat påvisas någon statistisk skillnad. / A good insight in the economic market leads to a favorable position from which we can maximize the profits of our investments. Is it possible to make such investments with regards only to the size of the companies we are considering? Numerous studies have been made on the small firm effect as an anomaly of the capital market. The effect supposedly tells us that, given the same period of time, small companies generates a higher percentage return than large companies. This contradicts the Efficient-market hypothesis, and the purpose of this research is to analyze whether this could be true, or not. The research study is made with regards to micro-size companies in the Swedish capital market during the years 2005-2014, thus, this is an extreme version of the small firm effect. A quantitative statistical analysis is used to measure the average return of three different stock portfolios; Large Cap, Small Cap and Aktietorget. Three different hypothesis are tested and the results analyzed with the help of statistical T-tests in SPSS are used. The results of the study is that there is no solid statistical proof that there is a difference in profit between the three different markets during the time period. Nor could an effect be seen during any smaller time period within the given time frame.

In Sweden, savings in funds today is one of the most popular forms of savings. Through both active and passive choices, almost all Swedes are exposed to the fund market, where mutual funds are the most popular type of funds. A clear majority of these funds are actively managed, which means that one or more fund managers actively work with the investments of the funds, with the aim to outperform the market. This method of management has been hotly debated in recent years, when many scientists claim that fund managers generally fail to outperform the market in long term. At the same time, interest in sustainability investments has increased in recent years, which is reflected in the fund market where sustainability funds have become increasingly popular. This essay therefore focuses on these sustainability funds, with focus on comparing large banks with web-based fund companies. The large banks in Sweden have been criticized for the way they are working seen from a customer perspective, but their funds are still very popular. Against this background, the study aims to investigate whether one can find any differences in performance of actively managed sustainability funds between large banks and web-based fund companies. Using four different models to measure risk-adjusted return of security portfolios, the funds have been examined to see if it is possible to find any patterns in terms of performance and the type of company that manages the funds. The survey results show that there is a clear difference in performance between the large banks and the web-based fund companies, whereby the latter succeed much better. Of the four models used, the large banks do not outperform the market under one model, while the web-based companies manage to outperform the market according to three of the models. Thus it can be stated that if you are interested in saving money in actively managed sustainability funds, it is the web-based companies to turn to. As previously mentioned, the large banks funds are very popular, which means that Swedish private investors have much money to gain by allowing web-based companies to manage their money, rather than large banks.

Background: Underpricing is the most studied area in the subject of IPO. The phenomenon is mainly described as a compensation for the risk of investing in a newly introduced company. Underpricing of shares is explained for many reasons, but the main reason is assumed to be the presence of asymmetric information on the market. Due to differences in financial systems between different countries, creates an incentive to conduct this study on the swedish market. Purpose: The purpose with this essay is to study the short term profitability of IPOs on the swedish market Method: The study is based on a quantitative research design with a deductive approach. The main method is the well established Event Study Method used by MacKinlay (1997), to measure the abnormal return of initial public offerings from the first-day return up to the following month’s return. Research has included 179 publicly traded incorporated companies on the swedish market between the years 2010 to 2020. Conclusion: The authors concluded, through analysis of the empirical basis with relation to previous studies and theories, drawn their own conclusions. Initial public offerings historically show higher returns compared to the market index. The study shows an abnormal first-day return of 0,4490%. Based on an analysis of the empirical results, it was found that the results were consistent and corresponds with previous research in the field of IPOs in other markets. In addition, the selected variables, namely the initial return of 9,21% as a result of IPOs, could partially interpret the abnormal first-day return as well as the following week’s and month’s. The other variables did not appear to be of statistical significance during any of the study periods. / Bakgrund: Underprissättning är det mest undersökta området inom ämnet börsintroduktion. Fenomenet beskrivs huvudsakligen som en kompensation för den risk som råder vid investering i ett nyintroducerat bolag. Underprissättning av värdepapper förklaras ha många anledningar men främsta orsaken antas vara på grund av närvaron av asymmetriska informationen på marknaden. Med skillnader i finansiella system mellan olika länder, skapar detta incitament för att genomföra denna studie på den svenska marknaden. Syfte: Syftet med denna uppsats är att studera kortsiktiga lönsamheten för IPO investeringar på den svenska marknaden. Metod: Studien utgår från en kvantitativ metod med deduktiv ansats. Undersökningens huvudsakliga metod utgick från den väletablerade Event Study method nyttjad av MacKinlay (1997), för att mäta den abnormala avkastningen från initiala erbjudandet efter börsintroduktion för första-dagsavkastning samt upp till en månad framåt. Studien omfattades av 179 publika aktiebolag på stockholmsbörsen mellan åren 2010 till 2020. Slutsats: Författarna har genom analys av det empiriska underlaget med koppling till tidigare studier samt teorier dragit egna slutsatser. Börsintroduktioner visar historiskt tillföra högre avkastning jämfört med marknadens index. Undersökningen visar en abnormal första-dagsavkastning på 0,4490%. Utifrån analys av resultatet, visade det sig att resultatet var konsistent samt överensstämde med tidigare forskning inom området börsintroduktion på andra marknader. Dessutom, kunde vi av de utvalda variablerna, nämligen den initiala avkastningen på 9,21% till följd av IPOs, delvis tolka den abnormala första-dagsavkastningen samt för efterföljande vecka och månad. De övriga variablerna visade sig inte vara av statistisk signifikans i någon av undersökningsperioderna.
