Syfte: Syftet med studien är att genom en eventstudieundersöka om och i sådan fall hur investerare låter sina investeringsbeslut påverkas av positiva respektive negativa sociala CSR-händelser, denna reaktion antas avspeglas i förändringar av aktiekurser. Teori: Den effektiva markandshypotesen och IntressentmodellenMetod: Undersökningens metod har utgått ifrån en kvantitativ ansats. Studiens empiri består av 86 sociala CSR händelser där den genomsnittliga ackumulerade abnormala avkastningen har mätts genom en eventstudie. I empiri-kapitlet finns även studiens hypotesprövning med enkelt t-test. Empiri: Eventstudienfinner ett samband mellan sociala CSR-händelser och investerares investeringsbeslut. Sambandet ger en negativ effekt på aktiekurserna. Effekten är starkare vid negativa sociala-CSR händelser än vid positiva. Hypotesprövningarna resulterade i att samtliga tre hypoteser förkastades, vilket innebär att det inte finns något samband mellan sociala CSR-händelser och investerares investeringsbeslut. Analys: Marknaden antas vara semi-effektiv, något mer vid negativa sociala CSR-händelser än positiva. Investerarna som är en primär intressent i ett företag värderar inte socialt CSR-arbete. Eventuellt ser de till och med det som värdeförstörande. Det är någon annan intressent än investerarna som driver på arbetet med socialt CSR hos ett företag. Slutsats: Eventstudienfinner ett samband mellan sociala CSR-händelser och investerares investeringsbeslut. Hypotesprövningarna resulterade i att samtliga tre hypoteser förkastades, vilket innebär att det inte finns något samband mellan sociala CSR-händelser och investerares investeringsbeslut. De motstridiga resultaten leder till slutsatsen att det inte med säkerhet går att besvara det undersökta problemet. / Purpose: The purpose of the study is, through an event study to determine whether if, and in such case how investors let their investment decisions be influenced by positive and negative social CSR events. This reaction is assumed to be reflected in changes of share prices. Theory: Theefficient market hypothesis model and the stakeholder theory.Method: A quantitative approach in the methodology has been undertaken. The study's empirical data consists of 86 social CSR events, where the average cumulative abnormal return has been measured by an event study. Three hypotheses has been tested using the simple t-test. Empiricism: The event study finds a correlation between social CSR events and investor's investment decisions. The correlation has a negative effect on stock prices. The effect is stronger for the negative social CSR events than for the positive events. Hypothesis tests resulted in that all three hypotheses were rejected, which means that there is no connection between the social CSR events and investor's investment decisions. Analysis: The market proves to be semi-strong efficient, slightly more so for negative social CSR events than for positive events. Investors as a primary stakeholder in a company do not value social CSR-work. Possibly they even see it as value destructive. There is other stakeholders than investors in companies, that are initiating working with social CSR. Conclusion: The event study finds a correlation between social CSR events and investor's investment decisions. The hypothesis tests resulted in that all three hypotheses were rejected, which means that there is no connection between the social CSR events and investor's investment decisions. The conflicting results leads to the conclusion that it is not possible to answer the investigated problem with sertainty.

The aim of this paper is to test whether an investment strategy originally created by Piotroski (2000), can be refined by combining it with the price-to-earnings-anomaly. In detail, we accomplish this by implementing Piotroskis F_SCORE-model to identify and consequently separate financially weak- and strong firms. Furthermore, we create an investment portfolio based on a combination of the highest rated companies according to the F_SCORE-model, and the most undervalued companies from the price-to-earnings-anomaly, to create a joint investment strategy (M_STRAT). This is carried out during the time-period 1999-2009, while reconstructing the portfolio annually. The results of our study show that, by combining the two models, we are able to achieve a market-adjusted return of 44,1%, hence amplifying the original F_SCORE-model by 17%.

This research report examines the cost and benefits of the Sarbanes-Oxley Act of 2002 (SOX) on South African companies who have had to comply due to them or their holding companies being listed on the New York Stock Exchange (NYSE) as well as voluntary adaptors of the code. This report further seeks to identify best practices implemented by these companies.

Western countries, institutions, and people from all walks of land, including Africans, have carried the notion that it is riskier to invest in African countries compared to countries in other continents. This study verified if that notion is empirically established or it is just a mere notion born out of people's imagination and unfounded belief. The study did select one special metal mining company listed on the New York stock exchange from every continent using a systematic random sampling of period five. All these stocks' data were daily data spanning the period 2003-06 - 2020:06 obtained from Yahoo Finance. The said duration was used for the analysis because one of the companies selected for the study only had stock data starting from 2003-06-25. Because of Generalized Autoregressive Conditionally Heteroscedastic (GARCH) ability to model the conditional randomly varying volatility, the study trained several of them for a different order of the GARCH terms σ2, and the order of the ARCH terms ε2 and for different distributions. Based on the AIC and BIC, the GARCH model that best fitted the data was GARCH (1,1), thus order one of the GARCH terms σ2 and order one of the ARCH terms ε2 based on student-t innovation. The study proceeded to estimate the risk measure using three of the approaches (risk metrics, Block Maxima Method under extreme value situation, and Generalized Pareto Distribution (GPD) for the tail ends of the distribution). None of the approaches or methods used in calculating VaR or conditional VaR (ES) of the stocks supported the conventional beliefs and age long-held purported gospel that African counties are the riskiest to invest on earth. In the risk metrics approach, the African stock was second riskiest to European stock. At the same time, in extreme value situations, it was third to European and South American; with GPD, it was third once again to South American and European stock. The study proceeded to verify if this founding were statistically significant. Applying analysis of variance (ANOVA), found that none of the differences established above is statistically significant. Meaning, statistically, the value and conditional value of one's investment that will be at risk is not different based on the investment's continental location. Thus, it is not statistically riskier to invest in one continent than the other.

A rational long-horizon stock investment decision is a complex process due to uncertainty in supply and demand, competitive advantage, macroeconomic parameters and various perspectives of investors. Today, the '€˜non-tangible assets'€™ (NTA) that include goodwill and intangible assets are a significant part of corporate assets, but their role in stock performance has not well studied. The purpose of this research is to empirically analyze the implications of NTA and of gross domestic product (GDP) of the United States on the stock price. According to the efficient market hypothesis, stock price reflects all relevant information. The research question focused on the extent to which NTA and the GDP reflected in the stock price. To determine the extent to which NTA and GDP reflected on the stock price, regression analysis and other statistical tests were used. The sample for the empirical study was 56 corporations listed on the New York Stock Exchange (NYSE) and National Association of Securities Dealers Automated Quotation (NASDAQ). The required data from October 2007 to September 2018 were collected from the United States Securities and Exchange Commission (SEC) and the United States Bureau of Economics (BEA). The key findings of the study are: the NTA and stock price of 45 corporations have a statistically significant correlation as opposed to 11 corporations. The combined NTA of these 11 corporations for the third quarter of 2018 was $531.64 billion. Furthermore, the GDP and stock price of 53 corporations have a statistically significant correlation, but no evidence for three corporations was found. The significance for positive social change is knowledge from this research about the implications of NTA and GDP on stock performance that the investors, policymakers, and other stakeholders could use for preserving the limited resources and creating wealth.

This study analyzes corporate governance practices of foreign (non-U.S.) issuers listed on the New York Stock Exchange (NYSE) and Nasdaq. Specifically, I examine the extent to which these foreign issuers voluntarily comply with U.S. stock exchange corporate governance requirements applicable to domestic issuers. My sample consists of 201 foreign companies primarily domiciled in Brazil, China, Israel, and the United Kingdom. I find that 151 (75 per cent) of the sample firms do not elect to comply with any of the U.S. corporate governance requirements. Logistic regression analysis generally supports the hypotheses that conformance with U.S. GAAP and percentage of managerial ownership are positively associated, and that percentage ownership by major shareholders is negatively associated with foreign firms electing to comply with U.S. corporate governance rules. This evidence is relevant for regulators and investors.

Merger & Acquisitions has been one of the more central themes of the financial sphere since the beginning of the 19th century. It is an activity that is necessary for firms since it can give them competitive advantage in their markets. An acquisition can give the acquiring firms the possibility to enforce cost and revenues efficiencies, as well as the prospect of entering new markets in order to differentiate themselves. Due to the increased activity of acquisitions and its impact on global economy, there has been a development of several strategies and procedures of what shall be taken into account before and during the acquistion itself. One of the latest factors that has been on an uprising in this discussion is the importance of sustainable factors for the acquirer.  Sustainable finance has become a topic of high relevance in the past few years due to the effects of climate change, but also in regard to questions that concern the firms social and managerial contributions. New policies, regulations and standards have submerged and has therefore created a new environment for the firms to adapt after. A commonly discussed framework in the area of sustainability is ESG. ESG har the purpose of assessing and measuring a firm's contributions to sustainability from an environmental, social, and governance perspective. This framework has been lifted in many studies as one of the more influential factors among investors and managers when discussing the profitability of a firm, as well as its strategic prospects in the sector. Lately, it has also been a subject discussed among M&A researchers as well as professionals, with many arguing that ESG will be even. more important part of the merger process due to its influence on the value of the firm and its financial performance.  The aim of this study is to see what kind of correlation there is between the financial performance of an acquiring firm and its ESG scores. This will be analyzed among firms that are listed on the New York Stock Exchange and NASDAQ stock exchange that have performed at least one acquisition between 2017 and 2023. This can give the managers a glimpse of a possible pattern that might be present between acquisitions and ESG scores, since the main aim of an acquisition is to improve the firm’s financial performance. The results that can be drawn from this study is that there is a positive and statistically significant correlation between financial performance and ESG scores among these firms. This may create a new, more modern agent problem where the management is opening up more for external stakeholders over their shareholders, which can be viewed as a consequence of stronger corporate social responsibility taken by the firms.

This thesis compares various attributes of the two stock exchanges that are currently in existence in the Czech Republic: the Rm-system Czech Stock Exchange and the Prague Stock Exchange. Detailed comparisons are made between various specifics of membership policies, trading routines, fees and indices at these exchanges and these are then related to the corresponding attributes at two representative foreign exchanges: the London Stock Exchange and the New York Stock Exchange. A principal question to be answered in the thesis is whether having two independent organizers of stock-market trading is beneficial to the investors and overall practical for the market of the size of the Czech Republic. The first, theoretical part of the thesis is focused on historical evolution and characteristics of the stock exchanges. In this part we give a general classification of stock exchanges, discuss in some detail the kinds of traded financial instruments, describe trading participants and elucidate the nitty-gritty of trading systems. The second, practical part of the thesis then examines detailed facts about individual stock exchanges in the order listed in the theoretical part with the emphasis put on the differences between the stock markets under study. Various representative data is collected in tables and/or recorded in charts and graphs. Particular distinctions between the stock exchanges are analyzed and the distinguished aspects are highlighted. The conclusion summarizes obtained results and finally answers, in the mild affirmative, the question whether it is beneficial to have the stock market in the Czech Republic served by two independent stock exchanges.
