Screening models are tools for predicting which stock are the most likely to perform well on a stock market. They do so by examining the financial ratios of the companies behind the stock. The ratios examined by the model are chosen according to the personal preferences of the particular investor. Furthermore, an investor can apply different weights to the different parameters they choose to consider, according to the importance they apply to each included parameter. In this thesis, it is investigated whether a screening model can beat the market average in the long term. It is also explored whether parameter-weight-optimization in the context of equity trading can be used to improve an already existing screening model. More specifically, a starting point is set in a screening model currently in use at a successful asset management firm, through data analysis and an optimization algorithm, it is then examined whether a programmatic approach can identify ways to improve the original screening model by adjusting the parameters it looks at as well as the weights assigned to each parameter. The data set used in the model contains daily price data and annual data on financial ratios for all stocks on the Stockholm Stock Exchange as well as the NASDAQ-100 over the time period 2004-2018. The results indicate that it is possible to beat the market average in the long term. Results further show that a programmatic approach is suitable for optimizing screening models.

This study employs a quantitative approach to investigate the momentum phenomenon in the commodity futures market. The study captures the phenomenon using two momentum indicators, namely, MACD and RSI, and extends the scope of indicator utilization to both joint and single usage. The research aims to explore whether portfolios consisting of these indicators can generate abnormal returns in the commodity futures market, in comparison to the S&P GSCI, which was used as the benchmark index. The study uses accumulated data from 2010 to 2019, with portfolios constructed on a quarterly basis. Statistical significance determination is executed by exporting the data to Stata, where the normality distribution is ascertained using the Shapiro-Wilk test. This was later followed by t-tests in order to dictate statistical significance on each portfolio compared to the S&P GSCI. The study reveals empirical evidence to support two of the three strategies, namely, the joint use of the aforementioned momentum indicators and single use of the RSI momentum indicator. However, the accumulated yield of the portfolio provided insufficient results to conclude the statistical significance of the single use of the MACD momentum indicator. The authors derive these results and observed phenomena from several financial theories, which are divided into three main sections in the theoretical framework, including information-based, risk-based, and behavior-based explanations. Relevant theories are included to support the research at hand. Furthermore, the authors incorporate the Efficient Market Hypothesis (EMH) under the pretense of challenging its view on efficient markets. They do so by constructing portfolios which yield abnormal returns and subsequently question the notion of efficient markets. The authors deduct that their findings produce some evidence to support the absence of strong form and semi-strong form of market efficiency in the commodity futures market. Overall, this study provides valuable insights into the momentum phenomenon in the commodity futures market and different incorporating investment techniques in which they are utilized. The ways in which momentum strategies can be utilized and momentum indicators interpreted, as displayed in this thesis, presents practical implications for investors and financial professionals.

Post Earnings Announcement Drift (PEAD) is a market anomaly that challenge the “Efficient Market Hypothesis” (EMH). It was first discovered in 1968 by Ball and Brown. When firms on the stock market have their earnings announcement the stock price will be affected and tend to drift up or down in price for days, weeks or months. Based on the limited research studies available there is acceptance that PEAD exists in the Stockholm stock exchange but depending on how measured the effect can strongly differ. In this master thesis we will study PEAD anomaly in the Swedish stock market and how pronounced it is on the stock’s sector, beta and trading volume. This study is an event and quantitative study which analyses firms on the Stockholm exchange market during the period between January 2007 to December 2022. A price measurement methodology has been used where the benchmark for abnormal (or excess) returns is the index of the list. Evidence shows that PEAD is present in the Stockholm Stock Exchange but that the effect is limited. The fact that the event abnormal returns are significant regarding of the returns up to after 60 trading days (although on a very small effect) provides insight and understanding of the effect. This study has also provided insight that beta and sector is a relevant PEAD parameter, maybe as important as the abnormal returns in the event itself. Trading volume have not provided any insight on PEAD in this study.

Titel: Svenska småbolagsfonders prestation i förhållande till OMXSGI   Nivå: Examensarbete på grundnivå (kandidatexamen) i ämnet företagsekonomi     Författare: Pontus Fogelberg   Handledare: Alice Schmuck   Datum: 2023 – januari   Syfte: Svenska aktiemarknaden är sällsynt som studieobjekt. Då andra marknader skiljer sig från den svenska behöver den granskas ytterligare för att investerare ska ha goda förutsättningar. Syftet är att undersöka förutsättningar för överprestation mot den svenska marknaden genom att investera i svenska småbolagsfonder. Syftet uppfylls genom att följande frågeställning besvaras: Hur ser möjligheterna ut för att över en femårsperiod, respektive treårsperiod, generera en högre avkastning om man investerar i svenska småbolagsfonder jämfört med hela stockholmsbörsen?   Metod: Genom en kvantitativ ansats har sekundärdata i form av avkastning från fonder och OMXSGI under perioden 2007–2022 legat till grund för t-tester.   Resultat och slutsats: Resultatet visar på hög sannolikhet att svenska småbolagsfonder genererar en högre avkastning än OMXSGI under en period på tre respektive fem år. Studien visar även på att risken i form av standardavvikelse är högre hos fonderna, men att den risken blir mindre relevant vid längre tidsperioder.   Examensarbetets bidrag: Studien bidrar med kunskap om hur investerare på den svenska marknaden kan få en högre avkastning än genomsnittet.   Förslag till fortsatt forskning: Utifrån studiens resultat och begränsningar kan vidare studier göras för att se om svenska småbolagsfonders riskjusterade avkastning är högre än OMXSGI. Om så är fallet kan prissättningsmodeller undersökas för att bidra till att besvara om svenska marknaden är effektiv eller ej.   Nyckelord: Småbolagsfonder, OMXSGI, avkastning, effektiva marknadshypotesen, småbolagseffekt. / Title: Swedish small cap funds' performance in relation to OMXSGI   Level: Student thesis, final assignment for Bachelor Degree in Business Administration.   Author: Pontus Fogelberg   Supervisor: Alice Schmuck   Date: 2023 – January    Aim: The Swedish stock market is rarely an object of study. As other markets differ from the Swedish one, it needs to be examined further so that investors have good conditions. The purpose is to investigate the conditions for outperformance against the Swedish market by investing in Swedish small cap funds. The purpose is fulfilled by answering the following question: What do the possibilities look like over a five-year period, or a three-year period, to generate a higher return if one invests in Swedish small cap funds compared to the entire Stockholm stock exchange?   Method: Through a quantitative approach, secondary data in the form of returns from funds and OMXSGI during the period 2007–2022 have been the basis for t-tests.   Results and conclusions: The result shows a high probability that Swedish small cap funds generate a higher return than OMXSGI over a period of three and five years respectively. The study also shows that the risk in the form of standard deviation is higher with the funds, but that this risk becomes less relevant over longer periods of time.   Contribution of the thesis: The study contributes knowledge about how investors in the Swedish market can get a higher than average return.   Suggestions for future research: Based on the study's results and limitations, further studies can be done to see if the risk-adjusted return of Swedish small cap funds is higher than OMXSGI. If this is the case, pricing models can be examined to help answer whether the Swedish market is efficient or not.   Key words: Small cap funds, OMXSGI, return, efficient market hypothesis, size effect.

This research paper studies the Day-of-the-week effect in the cryptocurrency market. Using multiple regression, we analyze the effect using 12 counterfactual optimized portfolios of the cryptocurrencies, as well as the 10 cryptocurrencies alone. Our findings show that well-optimized cryptocurrency portfolios are not subject to Day-of-the-week effects. A positive Monday and a negative Thursday effect were confirmed in Bitcoin, Ethereum, and Ripple, as well as a negative Sunday effect for Ripple.

Syftet med denna studie är att undersöka om det förekommer abnormal avkastning påaktiemarknaden hos de tio största amerikanska företagen inom restaurangbranschen isamband med Covid-19. I studien tillämpas teorierna Behavioral finance och den effektivamarknadshypotesen för att få en djupare förståelse kring restaurangbranschens aktiemarknadunder pandemin. En kvantitativ metod tillämpas i studien. En anpassad form av eventstudieanvänds innefattande marknadsmodellen för att räkna fram förväntad avkastning utifrånhistorisk statistik vilket sedan jämförs med den faktiska avkastningen under det så kalladeeventfönstret. Resultatet har visat att alla restaurangföretag utom ett som studerats i dennauppsats har påvisat en abnormal negativ avkastning under perioden 11 februari – 8 april år 2020 där Covid-19 var en framträdande nyhet i USA och resten av världen. / The purpose of the study is to investigate weather abnormal returns occurs in the stock marketamong the ten largest American companies in the restaurant industry in the timeline whereCovid-19 became a pandemic. The study applies theories from Behavioral finance and theEfficient market hypothesis to gain a deeper understanding of the restaurant industry’s stockmarket during the pandemic. A quantitative methodology is employed in this study. Anadapted form of event study is utilized, incorporating the market model to calculate expectedreturns based on historical data which is then compared to returns during the specified eventwindow. The results indicate that all restaurant companies, except one, examined exhibitedabnormal negative returns during the period from February 11 – April 8 the year 2020, when Covid-19 was a significant news story in the United States and globally.

Investing in the stock market offers opportunities for wealth accumulation through variousstrategies. This thesis explores the pairs trading strategy with dual-class stocks differingonly in voting rights, aiming to reduce portfolio risk and outperform the market bench-mark. Using data from the Swedish Large Cap index (2003-2023), the study benchmarksthe strategy’s performance against the OMXSPI index, assessing total return, CAGR andthe Sharpe ratio for three different strategies. Depending on the predefined thresholds ofthe trading strategy, the study concludes that pairs trading can surpass a buy-and-holdapproach, showing the effectiveness of a market neutral trading strategy.

Thesis advisor: Harold Petersen / Using insights from Hyman Minsky’s Financial Instability Hypothesis (FIH), we develop a theoretical framework for how speculative bubbles may materialize in securities markets. Our model and empirical analysis show that agents place undue emphasis on recent experience of risk and returns when developing future expectations. We use the aggregate investor allocation to equities (aggregate total market capitalization of equities divided by the price of all real liabilities outstanding), Tobin’s Q (the aggregate market price of equities divided by the replacement cost of nonfinancial firms’ assets), Shiller Total Return Cyclically Adjusted Price to Earnings Ratio (TR CAPE), and Shiller Cyclically Adjusted Price to Earnings Ratio (CAPE) as proxy variables for bubbles. We find statistically significant, negative relationships between all four of these proxy variables and two dependent variables, Subsequent Ten-Year Annualized Cumulative Equity Market Returns (Nominal and Real), and also Subsequent 10-year Average Losses, thereby providing evidence against the Efficient Market Hypothesis and suggesting the possibility of speculative bubbles. / Thesis (BS) — Boston College, 2019. / Submitted to: Boston College.

Syfte: Syftet med uppsatsen är att undersöka vad det finns för finansiellt syfte med att köpa namnrättigheterna för en arena där det i främsta fall bedrivs idrottsrelaterade evenemang. Delsyftet är att undersöka hur företagets aktiekurs påverkas vid tillkännagivandet av att de blir arenasponsor samt att se huruvida arenasponsorns aktiekurs påverkas efter att ett idrottsevenemang ägt rum. Metod: Undersökningen är en flerfallsstudie av fem företag där en metodtriangulering med en kombination av kvalitativ och kvantitativ metod används för att på så sätt ge en rättvis bild av fenomenet. Uppsatsen utgår från ett positivistiskt vetenskapligt förhållningssätt och ett deduktivt angreppssätt. Den kvalitativa delen av uppsatsen består av primärdata i form av intervjuer med personer från ansvariga positioner på företagen. Den kvantitativa delen består av en eventstudie-metodologi där den insamlade datan användes för att mäta om en avvikande avkastning (AR) uppstod i samband med tillkännagivelsen av namnrättighetsaffären samt en genomsnittlig avvikande avkastning (AAR) vid idrottsevenemangen. Utöver detta undersöktes även om specifika matchutfall påverkade företagens aktiekurs. Eventperioden för idrottsevenemangen sattes till dagen efter evenemanget medan eventperioden för tillkännagivelsen sattes till 75 dagar, 25 dagar innan och 50 dagar efter nyheten. Uppsatsens estimeringsperiod omfattade i båda fall 70 dagar. Resultat: Vid tillkännagivandet av arenarättighetsaffären uppvisar resultatet mellan en positiv AR på 2,48 procent till en negativ AR på 1,44 procent för de sex rättighetsaffärerna. Vid matchutfallen uppvisar resultatet allt från en positiv AAR på 0,26 procent till en negativ AR på -0,06 procent. Slutsats: Arenasponsringens stora finansiella vinning ges genom ett starkt varumärkeskapande vilket på sikt leder till ökade finansiella fördelar för företaget med namnrättigheterna av arenan. Finansiellt påverkades inte företagets aktiekurs av varken matchutfall eller tillkännagivandet av arenasponsringsnyheten. / Purpose: The aim of the thesis is to see what the financial purpose is for buying the naming rights of an arena where the main activity is sporting events. The subsidiary aim is to investigate if the company's share price is affected by the announcement that they became arena sponsors and to see whether the stadium sponsor's share price is affected after a sporting event has taken place. Methodology: The survey is one multi-case study of five companies, which are based on both a quantitative and a qualitative approach. The paper was based on a positivistic scientific approach and deductive approaches. The qualitative part of the thesis consists of primary data in the form of interviews with individuals holding responsible positions in the companies. The quantitative part consisted of an eventstudy, where the collected data is used to measure if an abnormal return (AR) has arisen in connection with the announcement of the name rights deal and an average abnormal return (AAR) in connections with the sporting events. Event period for sporting events is added to the day after the event while the event period for the announcement is added to 75 days, 25 days before and 50 days after the news. The surveys estimationperiod was comprised to 70 days. Results: At the announcement of the arena namingrights deal presented results from a positive AR of 2.48 percent to a negative AR of 1.44 percent. During the match, the outcome showed the results of a positive AAR of 0.26 percent to a negative AR of -0.06 percent. Conclusions: The big financial benefit of buying the naming rights of an arena is the strong brandbuilding which ultimately leads to increased financial benefits for the sponsoring company. The company's share price is not affected  by either match outcomes or the announcement of the sponsorship deal.

Purpose: To examine the relationship between a new movie release and the stock value of the movie producers in america, and seek a connection between movie criticts and the stock price with an attempt to find similar patterns with swedish movies and their financial performance. Theoretical Framework: Based on theories of effcient and ineffcient markets, behavioural finance and previous research in the field. Method: The study has a quantitative and a deductive approach. An event study method is used to examine five large movie studios in the USA, and the Swedish film producers are examined through the number of paying customers. Results: The results are shown i charts to explain the abnormal rate of return (AR) and the relationship between movie release and the AR. Furthermore, the movie critique is also represented charts. Both for the american and the swedish movies. Conclusion: The results show that an overall negative rate of return of -0,24 % occurs at the time of a movie release. A connection between stock price and movie release has been encountered. Positive film critique generates positive AR.
