Background: Mergers and acquisitions (M&A’s) are common ways for businesses to expand, compete, and maintain in competitive business environments. A strongly debated question in literature is whether or not these M&A’s provide measurable benefits, as factors such as industry, geographic location, and regulations play key roles in the impacts of the M&A’s. In this paper, we investigate the short-term effects of M&A’s based on stock returns of acquiring companies, with a focus on finance industries in the British Isles. Purpose: The purpose is to study whether or not there are significant short-term abnormal returns for acquiring companies when M&As of financial services target enterprises take place. Further, the study examines factors which can affect the impact of M&A’s, such as size of transaction, whether it is domestic or cross-border, whether or not the acquiring company is in a finance industry, and whether there is evidence of merger waves related to finance M&A’s in the British Isles. Method: An event study methodology is applied and focused on calculating the cumulative abnormal returns, as well as verifying whether those are statistically significant. The study analyses 100 M&A’s conducted on target companies from the UK and Ireland between the years 2000 and 2019. The event study is performed using the STATA statistical software, which is used to analyse the stock return performance in comparison to the domestic market index for each acquiring company. Conclusion: The study finds statistically insignificant results, concluding that M&A events do not generate significant abnormal returns for acquiring companies. This is in line with majority of previous research done, showing that M&A deals are not deemed significantly value creating nor value destroying. M&A’s within finance industry where the acquiring companies were domestic, in a finance industry, where the deals were smaller, were all shown to have less negative, albeit still insignificant results. This study also presents evidence for merger waves. Moreover, this thesis adds a clear geographic and industry component which is often missing in previous research, showing that within finance industry in the British Isles the impacts of M&A deals are unlikely to be statistically significant in causing abnormal returns.

The primary objective of profit-maximizing companies has long been seen as satisfying its shareholders. However, this orthodox view of corporate governance has been modernized as corporate social responsibility have become more relevant. In essence, corporate sustainability performance has evolved and is now divided into environmental, social and corporate governance, also known as ESG, closely scrutinized by all stakeholders.  The main purpose of this study is to investigate how ESG disclosures about Swedish-listed companies affect their market value. By analyzing these results, using both conventional and complementary theories in behavioral finance, the researchers in this study also aspires to add new perspectives to the research field on why and how the market reacts as it does. This aim was then fulfilled by quantifying the impact of 195 ESG news on market capitalization using three-event studies.  The results are sufficiently reliable to confirm both hypotheses of the study. The findings support both theories and previous research in the sense that deviations from the social contract between firms and stakeholders damage firms' legitimacy. Furthermore, the study’s results show that market reactions are asymmetric. Firstly, with the implication that the negative impact of negative news exceeds the corresponding positive impact of positive news. Secondly, with the meaning that positive news results in a negative impact on market value.  This can be attributed to market psychological factors and other factors, such as Swedish investors' valuation of sustainability work. In addition, the opposite market reaction to positive news is consistent with studies suggesting that certain ESG news are perceived as greenwashing. Against this background, the study concludes that companies' sustainability work and ESG compliance are not profitable to the extent previously advocated. However, the indirect cost of not acting in a socially responsible manner is greater than the opposite. / Det primära målet för vinstmaximerande bolag har länge ansetts vara att tillfredsställa aktieägarna. Denna ortodoxa syn på bolagsstyrning har dock moderniserats i takt med att hållbarhet och samhällsansvar blivit mer aktuellt. I huvudsak har bolagens hållbarhetsarbete utvecklats och delas numera upp i miljöfrågor, sociala frågor och bolagsstyrning, även kallat ESG, något som noga granskas av intressenter.  Det primära syftet med denna studie är att undersöka ESG nyheters inverkan på svensknoterade bolags börsvärden. Genom att analysera dessa resultat, med såväl konventionella som kompletterande teorier inom beteendeekonomi, ämnar författarna även att kunna bidra med nya perspektiv till forskningen om hur, men även varför, marknaden reagerar som den gör. Detta syfte har sedan uppfyllts genom att kvantifiera 195 ESG nyheters inverkan på börsvärde med hjälp av tre eventstudier.  Resultaten är tillräckligt tillförlitliga för att bekräfta studiens båda hypoteser. Fynden stödjer såväl teorier som tidigare forskning, i den mening att avvikelser från det sociala kontraktet mellan företag och intressenter skadar företagens legitimitet. Vidare visar studiens resultat att marknadsreaktionerna är asymmetriska. I första hand i det avseendet att den negativa inverkan från negativa nyheter överstiger den positiva inverkan från positiva nyheter. I andra hand i den bemärkelsen att positiva nyheter leder till en negativ inverkan på marknadsvärde.  Detta kan hänföras till marknadspsykologiska faktorer och andra faktorer, som exempelvis svenska investerares värdering av hållbarhetsarbete. Vidare är den motsatta marknadsreaktionen till positiva nyheter i linje med studier som antyder att vissa ESG nyheter kan tolkas som grönmålning. Mot denna bakgrund konkluderar studien att bolagens hållbarhetsarbete och efterlevnad av ESG inte är lönsamt i den utsträckning som tidigare förespråkats. Dock är den indirekta kostnaden för att ej agera socialt ansvarsfullt större än motsatsen.

Bakgrund: Med ökade styrräntor och stigande inflation har det blivit viktigt att förstå hur dessa förändringar påverkar ekonomin, företag och aktiemarknaden. Forskning visar att räntebesked kan påverka både aktiemarknaden och banksektorn med effekter på avkastning och volatilitet. Bankerna har som bekant en särskild funktion i den svenska ekonomin genom att svara för finansiering och betalningstjänster till näringsliv och offentlig sektor. Syfte: Studiens syfte är att undersöka de effekter som uppstår vid förändringar i Riksbankens styrränta på den svenska aktiemarknaden och inom banksektorn.  Metod: En kvantitativ eventstudie med en deduktiv forskningsansats har genomförts. Undersökningen består av sju olika observationer på ränteförändringar av aktier på den svenska OMX Large Cap-listan. De olika observationerna är räntehöjningar rapporterade av Riksbanken mellan åren 2019-2023.  Teori: Studien utgår från den effektiva marknadshypotesen vilket kompletterats med tidigare forskning om ränteförändringar och bankers påverkan av räntehöjningar.  Slutsatser: Studien finner inte bevis för statistiskt signifikant samband mellan Riksbankens räntehöjningar och den svenska aktiemarknaden. Inom banksektorn fanns inte heller tillräckliga bevis för att visa på en abnormal avkastning vid tillkännagivandet av ett räntebeslut. Resultatet stöds av den effektiva marknadshypotesen. De få resultat som visade på abnormal avkastning bör därför studeras vidare. Externa faktorer borde inkluderas för att förklara skillnaderna i reaktionerna på den svenska aktiemarknaden. / Background: With increasing policy rates and rising inflation, understanding how these changes impact the economy, businesses, and the stock market has become crucial. Research has shown that interest rate announcements can affect both the stock market and banks, influencing returns and volatility. Banks play a central role in the Swedish economy by offering financing and payment services. Purpose: This study aims to examine the effects of changes in the Swedish central bank's policy rate on the Swedish stock market and banking sector. Methodology: A quantitative event study with a deductive research approach was conducted. The study consists of seven different observations on interest rate changes affecting stocks listed on the Swedish OMX Large Cap List. These observations cover interest rate hikes reported between 2019 and 2023. Theory: The study is based on the efficient market hypothesis, complemented by previous research on interest rate changes and the impact of rate hikes on banks. Conclusions: The study shows no significant relationship between Swedish central bank's interest rate hikes and the overall stock market. Similar findings were observed within the banking sector. This can be explained by the efficient market hypothesis, which suggests that all relevant information is already reflected in stock prices. The efficient market hypothesis also supports the lack of market reactions, thus future research should consider external factors that could explain differences in reactions within the Swedish stock market.

This paper investigates whether greater investor distraction on the Swedish stock market during the summer months of June, July and August leads to a more pronounced post earnings announcement drift (PEAD) effect, during the ten year period between 2000 and 2009. PEAD is an anomaly whereby the information contained in earnings announcements is not immediately or completely incorporated into stock prices, in the cases where the announcement contains an ‘earnings surprise’. The methodology involves using the standardised unexpected earnings (SUE) metric to measure the level of ‘earnings surprise’ and a buy and hold abnormal returns (BHAR) trading strategy to measure return. The study tests and confirms the existence of greater investor distraction during summer months on the Swedish market. For a holding period of 12 months, a BHAR trading strategy generates a greater abnormal return for summer months (11.3%) compared with the abnormal return for non-summer months (10.5%). These results are also interesting in a broader context, as they confirm the existence of the PEAD effect, one of the strongest counter-arguments to the efficient markets hypothesis (EMH); the foundation of many financial models used for stock market valuation. This is because, according to the EMH, in an efficient market it should not be possible to generate abnormal returns based on available information. However, it may be noted that these results do not take into account transaction costs. This means that while it can be demonstrated that there is greater investor distraction during the Swedish summer, in order to implement a successful trading strategy based on this finding, further testing would be required. Therefore, based on the findings of this paper, a number of areas for future research have been identified.

Objective: Our purpose with this study is to demonstrate the impact of natural disasters on banks' share prices. Method: Quantitative survey method, an event study. Conclusion: There is no association or a very weak correlation in this study between natural disasters and the Swedish banks' share prices.

There are plenty of things said about the financial industry, an always ongoing debate, to say the least. We have identified a complex situation with three dimensions: Initial public offerings, Venture capital, and Lockup agreements. IPOs are generally difficult to put a price on because the market is not united yet, which creates uncertainties. Venture capital firms invest into startups, often with the incentive of bringing them to an IPO and then make a fast cash out exit. Lockup agreements are contracts that prevent insiders from dumping their shares during a set period in the beginning of the IPO. Additionally, based on the market efficiency theory, a market should always be efficient. But does it play out when these characteristics are affecting each other? The purpose of this research was to investigate whether there are abnormal returns in the financial performance for publicly listed companies on the London Stock Exchange at the end of their lockup period. We sorted on venture capital backed companies and sought to explore differences between VC backed, Non-VC backed firms, and the entire market. The research question for this study is: ‘Does The theoretical aspects of this research’s ontological and epistemological views were set in positivism and objectivism with a deductive approach. The financial performance was key in this research, and it was essential to get ample and appropriate data, therefore a quantitative research method was used with an archival research strategy and explanatory research design. We explored a big research gap in this area after the financial crisis 2008, which made us look at IPOs from 2009 to 2012 with an event window as our time horizon. To answer the research question and fulfill our purpose, four hypotheses were developed with focus on VC backed firms, Non-VC backed firms, the entire market, and one shorter event window. Our results prove that the market efficiency theory does not hold. To answer the research question, we found negative abnormal returns after the lockup expiration date for both Non- VC backed firms and the entire market. However, we were unable to provide a statistically significant result for VC backed firms. There was an extra clear trend during the middle 20 days, and we suggest and encourage to further research with a longer time horizon than [- 20, +20] days.

This thesis examines whether mergers and acquisitions (M&A), ranging from 2009 to 2020, are value-generating for acquiring shareholders in the short-term and long-term of companies listed on the Stockholm Stock Exchange. A cohesive and integrated theoretical framework is formed in which six firm-specific and deal-specific variables are hypothesized to have varying impacts on both short- and long-term stock performance for acquiring shareholders. An event study was conducted to measure the short-term stock performance, i.e. cumulative abnormal returns (CAR), and long-term stock performance, i.e. buy-and-hold abnormal returns (BHAR). We find that M&A transactions are, on average, value-generating for acquiring shareholders in both the short term and the long term. Among the significant findings of the variables examined, firm size was negatively related to short-term stock performance but positively related to BHAR. The relative size of the transaction was found to be positively related to CAR. Furthermore, transactions mediated with cash were found to be positively related to BHAR. Lastly, related transactions were found to be positively related to CAR, although not when accounting for robust standard errors.

Doctor of Philosophy / Department of Agricultural Economics / Ted Schroeder / Food recalls have been an issue of great concern in the food industry. Stakeholder responses to food safety scares can cause significant economic losses for food firms. Assessing the overall impact that may result from a food recall requires a thorough understanding of the costs incurred by firms. However, quantifying these costs is daunting if not impossible. A direct measurement of a firm’s total costs and losses of revenue associated with a food recall requires firm-level data that is not available. The method utilized in this study overcomes this severe limitation. Using an event study, the impact of meat and poultry recalls is quantified by analyzing price reactions in financial markets, where it is expected that stock prices would reflect the overall economic impact of a recall. A unique contribution of this study is evaluating whether recall and firm specific characteristics are economic drivers of the magnitude of impact of meat and poultry recalls on stock prices. Results indicate that on average shareholders’ wealth is reduced by 1.15% within 5 days after a firm is implicated in a recall involving serious food safety hazards. However, when recalls involve less severe hazards, stock markets do not react negatively. Also, reductions in company valuations return to pre-recall levels after day 20. Firm size, firm’s experience, media information and recall size are drivers of the economic impact of meat and poultry recalls. That is, firms recalling a larger amount of product perceive greater reductions in company valuations. Additionally, recalls issued by larger firms are less likely to present negative effects on stock prices, compared to smaller firms. Moreover, firms that have recently issued a recall are less harmed by a new recall compared to those firms issuing a recall for first time. Thus, suggesting that investors take into consideration the past performance of a company when dealing with food recalls. Furthermore, media information has a negative impact on shareholder’s wealth. Findings from this study provide essential information to the meat industry. In particular, understanding the likely impact of such “black swan” events is critical for firm’s investing in food safety technologies and protocols.

Antalet kvinnliga styrelseledamöter i bolag har ökat de senaste åren och studier visar att bolag med könsdiversifierade styrelser redovisar högre lönsamhet än andra företag. Flera av dessa studier är baserade på data från små, medelstora och stora börsnoterade bolag. Regeringen föreslog nyligen en kvoteringslag där kvinnor skall utgöra 40 procent av antalet styrelseledamöter i bolag med syfte att få mer jämlika styrelser. Intressant är då att studera om fördelarna med könsdiversifierade styrelser beaktas av investerare och hur marknadsaktörer agerar. I studien visas att när nominering av kvinnliga styrelseledamöter offentliggörs har det en negativ påverkan på företagets marknadsvärde, men denna påverkan är inte statistiskt signifikant. Vidare påverkas inte nomineringens inverkan på aktiekursförändringen av ett bolags branschtillhörighet. / The number of female directors of companies has increased in recent years and studies show that companies with diverse boards report higher profitability than other companies. Several of these studies are based on data from small, medium and large listed companies. The government recently proposed a quota law where women will constitute 40 per cent of the directors of companies to push for more equal boards. Hence, studying the benefits of diverse boards and its investor reactions and how the market is moving is of interest. The study shows that when the nomination of female board members is published, it has a negative impact on the company's market, but this effect is not statistically significant. Furthermore, the nomination affect does not have an impact on the stock price change regarding the company's industry affiliation.

The following dissertation contains two distinct empirical essays which contribute to the overall field of Financial Economics. Chapter 1, entitled “Financial Inclusion and Economic Development in OIC Member Countries,” examines whether the presence of Islamic finance promotes development and alleviates poverty. To do so, we estimate the influence of financial inclusion variables on development and poverty variables for OIC countries. Using data from the World Bank, we use dynamic panel analysis using methodology similar to Beck et al (2000) to study the effects of financial inclusion on economic development and use simple cross-sectional analysis similar to Beck et al (2004) to study the effects on poverty alleviation. We find that the countries with Islamic finance tend to outperform the rest of the world. We believe that the ability of financial institutions offering Shari’a compliant services to bring otherwise excluded people under the financial system plays a major role in increased development and reduced poverty in those countries. The results support our view that financial inclusion is causing development. Chapter 2 entitled, “Asymmetric Market Reactions to the 2007-08 Financial Crisis: From Wall Street to Main Street,” examines the impact of significant news events during the 2007 – 2008 financial crisis on the abnormal stock returns for portfolios of financial and real sector firms. We recognize 17 significant news events from 2007 and 2008 and create equity portfolios using daily CRSP data from January 1, 2006 to December 31, 2009. We estimate event announcement interval abnormal returns in the context of an asset pricing model similar to Fama and French (1993) and Carhart (1997). We document significant negative abnormal returns for the portfolio of non-financial firms, and the smallest firms exhibit the largest negative abnormal returns, an indication of a significant spillover of financial market news to real sector stock returns. Smaller financial firms also exhibit negative abnormal event returns, and these results are driven by broker-dealer, depository, holding-investment, and real estate firms. The results provide new evidence regarding the incorporation of news events into asset prices during financial crises.
