In the first essay titled “Monthly Cyclicality in Retail Investors’ Liquidity and Lottery-type Stocks at the Turn of the Month”, we find that the well-documented underperformance of lottery stocks masks a within-month cyclical pattern. Demand for lottery stocks increases at the turn of the month especially in areas whose demographic profile resembles that of the typical lottery-ticket buyers (i.e., gamblers) driving their prices higher at the turn of the month. This effect is particularly pronounced among firms located in areas whose demographic profile resembles that of the typical lottery-ticket buyer and propelled by the within-month cyclicality of local investors’ personal liquidity positions. A long-short investment strategy based on this cyclical pattern of lottery stocks performance yields gross abnormal returns of about 15% per year. In the second essay titled “Lottery-type Stocks and Corporate Strategies at the Turn of the Month”, we test whether cyclical demand for lottery stocks by retail investors, that tends to peak at the turn-of-the-month (ToM), affects firms’ financial activities. Consistent with the notion that the peak in demand is driven by a propensity to gamble and is associated with inattention, we find underreaction to earnings news issued at the ToM by lottery-type firms located in areas with many gambling investors. We also find that the ToM also provides a window of opportunity for SEO issuing lottery-type firms. Such issuing firms may strategically choose to issue lottery-type stocks at the ToM to save the direct marketing costs because it flattens the elasticity of pre-offer demand curve.

The objective of this research is to test human capital theory via the earnings announcements through the returns within the for-profit education and training services industry. This theory posits that enrollment levels would rise during recessionary periods and this should be reflected in better earnings announcements of the education firms. Data was retrieved from the Compustat, CRSP, Thompson IBES, Google Finance, and Yahoo! Finance databases spanning the recessionary years of 2008 through 2010. The first hypothesis utilized a price index weighted by the education firms' market capitalization and the Russell 3000 Index as a proxy for the market to assess the daily returns of the education industry relative to the market. The second and third hypotheses involved assessing the quality of the earnings announcements within the education industry on a Friday vs. non-Friday report basis. The fourth hypothesis explored the actual EPS vs. forecasted EPS in consecutive quarters to test for differences in the earnings of that are better-than and those that are the same-or-worse than expected. The final hypothesis utilized the cumulative abnormal returns and cumulative excessive returns methodologies to compare the performance of the periods before and after the announcements. No support for the first four hypotheses was found. Consistent with expectations established by other research using CAR and CER methodologies, the fifth hypothesis was supported. Support for human capital theory was not found because four hypotheses were unsupported. This study was limited to U.S. education firms that were publicly traded on major U.S. exchanges. No private for-profit or non-profit firms were included in this study. Knowledge was gained by exploring the earnings announcements of the education industry for evidence of human capital theory. The absence of support for the theory within the industry during a recession could be an indicator of other issues affecting the industry that need to be researched further before any conclusions can be reached. This study extends the research in earnings announcements by examining the relationship the education industry has with the market. It also contributes to the work in human capital theory by testing the education industry's performance during recessionary years.

Les investisseurs n’exploitent pas toujours toute l’information disponible lorsqu’ils prennent des décisions, en raison à la fois d’une surabondance de l’information et de capacités cognitives limitées. Le premier essai de cette thèse montre que les sociétés tirent parti de l’inattention des investisseurs en communiquant plus ou moins longtemps à l’avance la date à laquelle aura lieu les annonces de résultats. Des résultats positifs sont notifiés très en amont tandis que des résultats décevants font l’objet d’un délai de notification plus court. Le second essai traite de la visibilité internationale des sociétés et étudie l’impact d’une communication en anglais via des canaux de diffusion à grande échelle. Cette diffusion plus large augmente l’attention des investisseurs et les informations contenues dans les annonces de résultat sont plus rapidement intégrées dans le prix des titres. Le troisième essai traite des conséquences d’une visibilité accrue des sociétés sur leur politique d’investissement. Une diffusion élargie des informations financières améliore à la fois l’environnement informationnel des sociétés et l’efficacité de leur politique d’investissement. / Investors often fail to incorporate all relevant information when they make decisions. This is a consequence of both information overload and investors’ limited cognitive abilities. The first essay shows that firms take advantage of investors’ inattention by managing the advance notice period of earnings announcements. Firms notify the date of positive earnings announcement several weeks in advance while disappointing earnings are notified at late notice. The second essay deals with firms’ international visibility and studies how communicating on English-speaking wire services impacts investors’ attention. Higher dissemination of news increases investors’ attention and improves the incorporation of information into stock prices. The third essay deals with the effects of firms’ visibility on investment policy. It shows that higher dissemination of disclosures improves firms’ informational environment and investment efficiency.

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.

Cette thèse est composée de trois chapitres distincts. Le premier chapitre montre que les dirigeants réagissent de façon excessive face aux risques qui frappent l'attention. Après un ouragan, le choc produit par la catastrophe sur le risque de liquidité perçu conduit les entreprises situées dans le voisinage de la zone sinistrée à augmenter temporairement leur détention de liquidités alors que le risque réel n'a pas changé. Le deuxième chapitre montre que les dirigeants influencent de façon stratégique l'attention des investisseurs aux annonces de résultats en les prévenant plus ou moins tardivement de la date de l'événement. Cette stratégie leur permet de lisser dans le temps l'impact de mauvais résultats sur leur cours de bourse. Le troisième chapitre étudie l'effet des league tables dans les activités de fusions-acquisitions. Les league tables classent les banques d'investissement. Le rang d'une banque dans la league table prédit sa capacité à engendrer des affaires nouvelles dans le futur, ce qui incite les banques à manipuler leur classement. / This dissertation is made of three distinct chapters. The first chapter shows that managers overreact to salient risks. They respond to the occurrence of a hurricane event when their firms are located in the neighborhood of the disaster area. The sudden shock to the perceived liquidity risk leads them to temporarily increase the amount of corporate cash holdings, even though the real liquidity risk remains unchanged. The second chapter examines earnings announcements by US firms, and how far in advance notice of the event is given (the "advance notice period"). Such advance notice period affects how much investors pay attention to earning news. This variation in investors' attention affects short-run and long-run stock prices, thereby creating incentives for firms to strategically reduce the advance notice period when they plan to disclose bad news. The third chapter studies M&A league tables, which provide rankings of investment banks. The rank of a bank in the league table predicts its future deal flow. This creates strong incentives for banks to manage their ranks in the league table.

Almost two decades after the burst of the Dot-com bubble, investors are opinionated as to whether a new technology bubble has formed in the equities market. Similar to the late 1990's and early 2000's, many Internet firms today go through initial public offering without yet turning over a dollar of earnings, but boast certain revenue-associated performance metrics to investors promising of future success. However, investors are known to hold sentiments sensitive to earnings announcements (Seok, Cho & Ryu, 2019) and reward firms which meet or beat earnings with higher stock returns (Bartov, Givoly & Hayn, 2002). That raises a question on the content of earnings announcements: Besides earnings and cash flow, are there other factors that may influence investor decisions to trade some Internet stocks? My primary hypothesis is that the voluntary disclosure of specific non-financial key performance indicators (NFKPI) during earnings announcement by Internet firms influences the investors' investing/trading decisions. My motivation for this research is to understand better whether there is a strategic element in the voluntary disclosure of NFKPI in Internet companies and how it may impact investors' decisions. The results could be useful to firms in their evaluations of whether to release NFKPI or similar information and to equity research analysts as well as investors in measuring their expectations and valuations of the firms' stocks. The intention of the study is not to generalize the findings to the full market, as the number of companies with the practice of voluntary disclosure of NFKPI is comparatively few compared to those without the practice. Instead, this study examines the effects of NFKPI on the stock returns of those companies which choose to disclose it. I use event study methodology to test the statistical significance of disclosure of NFKPIs during earnings announcements. By controlling for earnings surprise and other meaningful financial ratios, I also examine how the signaling effect of NFKPI could be distinguished from the signaling effects of important information concurrently released during earnings announcements. I focus on two types of NFKPI within the Internet industry: Gross Bookings for online booking agency services and Daily Active Users for social media. As earnings reports and quarterly filings often do not necessarily come together on the same date, I hand-collected data to estimate the surprise effect of NFKPI per earnings announcement, by using available broker forecasts of the respective NFKPI as a proxy for the investor's NFKPI expectation. The results show that while revenue surprise remains consistently the most influential variable to investors, NFKPI Surprise has a positive, statistically significant relationship with the firm's abnormal returns. Additionally, despite being insignificant when expected earnings is beat or in line with consensus, NFKPI Surprise is found statistically significant with a positive relationship to abnormal returns when expected earnings is missed. In line with existing research on management's motivation to prevent negative earnings surprises (Matsumoto, 2002), these findings imply that if firms could employ the voluntary disclosure of NFKPI to manipulate investors' impression and to cushion their stock prices against potential negative market reactions when earnings is missed.

The study examined the impact of earnings announcements on the share price of selected mining companies using the most recent data from the Johannesburg Stock Exchange. This study covered a period from 1 January 2011; to 31 December 2015. Using the classical event study methodology, the speed of reaction of the market to annual earnings information releases for a sample of 27 companies listed on the exchange is tested. Over the sample period, the Abnormal Returns (AR), Average Abnormal Returns (AAR) and Cumulative Average Abnormal Returns (CAAR) were calculated. The AR, AAR and CAAR show positive results obtained during the earnings announcement period. The returns yielded from these results are significantly different from zero. / Financial Accounting / M.

We evaluate the impact on prices of the company's stocks with an Event Study. As a control, we analyzed the effects of the disclosure of 1,152 quarterly earnings announcements on other 48 stocks that are part of the IBOVESPA´s theoretical portfolio in the period between 2010 and 2015. We seek to identify the presence of abnormal returns and verify that all information is automatically transferred to prices, suggesting the semi-strong efficiency of the Brazilian stock market in accordance with the Market Efficiency Hypothesis (EMH) developed by Fama (1970). At the end we compare the results of the two specific earning announcements studied with the observed results of other earnings announcements of Petrobras. No evidence was found of market efficiency during the 2010-2015 period neither for the group of 48 stocks, NÃO_PETRO, nor for the PETRO group, formed by the two Petrobras shares. We then analyzed the results in two periods. The first, called Bonanza (2010-2013), showed the same results as the 2010-2015 period, with no significant abnormal returns in the event window [0,1]. The results of the Crisis period (2014 -2015) showed that the information of the earning announcements ha a statistical significant impacted on the prices of the studied stocks. To analyzing the results of the individual earning announcements of Petrobras, we identified the need for additional information, extrapolating the scope of an event study. / Este trabalho propõe-se a estudar os efeitos sobre as ações da Petrobras decorrentes da apresentação dos balanços do terceiro e quarto trimestre de 2014, primeiros balanços apresentados após as denúncias da Operação Lava Jato. Avaliamos os impactos nos preços das ações da empresa através de um Estudo de Evento. Como controle, analisamos os efeitos da divulgação de 1.152 balanços trimestrais sobre outras 48 ações de que fazem parte da Carteira Teórica do IBOVESPA no período entre 2010 e 2015. Buscamos identificar a presença de retornos anormais e verificar se toda informação se transfere automaticamente aos preços, sugerindo a eficiência semiforte do mercado de ações brasileiro de acordo com a Hipótese de Eficiência do Mercado (HEM) desenvolvida por Fama (1970). Ao final comparamos os resultados específicos dos balanços em estudo com os resultados observados em outros balanços da própria Petrobras. Não foram encontradas evidências de eficiência de mercado durante o período 2010-2015 nem para o grupo de 48 ações, chamadas de NÃO_PETRO, nem para o grupo PETRO, formado pelas duas ações da Petrobras. Ao dividir os mesmos grupos em dois momentos, os resultados para o período batizado de Bonança (2010-2013), permanecem iguais ao do período completo, ao passo que o período chamado de Crise (2014 -2015) apresenta retornos anormais estatisticamente significativos nas janelas de eventos. Ao avaliar os retornos de balanços individuais da Petrobras, identificamos a necessidade de informações adicionais, extrapolando o escopo de um estudo de evento.
