IPO underpricing is a phenomenon found in all markets worldwide. Investors are always looking for a good opportunity of short-term abnormal positive returns, and the IPOs first-day trading returns have been a good investment strategy for both institutional and private investors in all markets of the world. This study consists at an investor’s perspective analysis of the first-day returns of 59 IPOs listed on the Brazilian Stock Exchange Market from January 2004 to April 2007, where I have found a significantly mean positive underpricing of 6,60%. I have found also some evidences of a sprouting “hot-market” period in Brazil, since the number of the IPOs in Brazil has been growing almost in an exponential speed, taking advantage of the constant growing cash inflow and liquidity of the Brazilian market, followed by the high evaluation of the Ibovespa Index, with return of 140% on the study time frame. When categorizing the study by year, by underwriter (investment bank) and by market segment, I always have found positive adjusted initial returns, which corroborates the fact that underpricing is a constant phenomenon in the Brazilian market. Other important facts that were identified in this study is that the average returns of the IPOs are decreasing along the years and that companies that depend to a large extent on their human capital and are in the business areas that are staff intensive have a high level of underpricing while companies that have a high level of fixed assets have a low level of underpricing. Finally, after performing a multivariate linear regression analysis with the chosen independent variables on the full sample and some categorized samples, the results did not have enough statistical significance and consistence that could make them useful to create a statistical model to explain the underpricing level of Brazilian IPOs between January 2004 and April 2007.

This study examines the affect of winning an Academy Award on the stock price of parent companies. On average, receiving an Oscar has no significant impact on the stock of parent companies during the few days surrounding the broadcast of the Academy Awards. The findings of this study introduce questions of external interference and possible limitations on this type of research. However, my study sheds light on future topics of investigation for analyzing the effects of televised award shows on the stock market.

I denna studie har aktieutvecklingen hos förvärvade börsnoterade företag vid budets offentliggörande studerats. Företagen som förvärvades under lågkonjunkturen år 2007-2009, och högkonjunkturen år 2001-2004 har undersökts för att se om det finns någon skillnad i aktieprisutvecklingen som skulle kunna bero på vilket tillstånd ekonomin i samhället befinner sig. Därefter utreds om det finns en skillnad beroende på vilken bransch företagen befinner sig i. Studien förankras teoretiskt ur den effektiva marknadshypotesen där en semistark effektiv marknad antas. Denna grad av effektivitet antas vanligen för finansiella marknader och är den form som eventstudier utgår ifrån. Den undersökningsform som används i denna uppsats är en eventstudie och denna statistiska metod mäter marknadens reaktion på ny information. Den abnorma avkastningen har beräknats vilket sedan belysts genom tabeller och diagram, vilka i sin tur tolkats av en analytiker. Studien resulterade i att företagsförvärv i lågkonjunktur har högre abnorm avkastning än uppköp som sker under högkonjunktur. Uppsatsen uppvisade även att kommunikationssektorn hade en högre abnorm avkastning än resterande branscher. / Share development of acquired companies listed at the bearer's publication has been studied. Companies acquired during the recession years 2007-2009 and the boom years 2001-2004 have been studied to see if there is any difference in the share price that would depend on what cyclical the economy in the society is. I have further investigated whether there is a difference depending on what industry the companies are active in. The study is anchored in theory from the efficient market hypothesis in which a semi-strong efficient market is assumed. This degree of efficiency is usually assumed in financial markets and is the form that event studies adopt. The survey form used in this paper is an event study and this statistical method measures the market’s reaction to new information. The abnormal return is calculated which is then illustrated by tables and charts, which in turn is interpreted by an analyst. The study showed that acquisitions in the recession had higher abnormal returns than purchases made during the boom. The paper also showed that the communications companies had a higher abnormal return than the remaining sectors.

This thesis examines the impact of company announcements on the daily stock returns of lowly capitalised companies. A total of 105 companies comprise the sample and 1464 events are examined over the period 21110/97 to 03/0412000. The methodology employed is primarily, empirical in nature. Event studies are conducted to gauge the impact of company announcements on stock returns using the single index market model (SIMM) as the chosen equilibrium market model for modelling abnormal returns. The study professes three mam contributions to knowledge. The empirical evidence suggests that financial announcement have a more timely impact on stock returns than non-financial announcements. Secondly, there appears to be significant over-reaction and mean-reversion exhibited by lowly capitalised firms. Thirdly, the speed of adjustment of stock prices to new information is increased in cases where shareholder concentration is high while over-reactions appear inversely proportionate to shareholder concentration. This may be a consequence of smaller firms experiencing leakage of boardroom level information prior to public announcement days.

Many studies have been performed on the short- and long-run abnormal returns to acquirers in acquisition attempts, but the topic of bidding wars is relatively unexplored. This piece performs an in-depth analysis of daily returns to both the public winners and losers in bidding war situations. It provides a counterargument to earlier findings that found that winners in bidding wars performed poorly compared to losers. I also fill in the gap in the analysis of short-term returns to paired winners and losers during and surrounding the bidding war. I find that winners perform significantly better than losers during certain critical periods in the bidding war, and this appears to signal the increased likelihood of the winner’s success. However, in the short-term, the market consistently misjudges the direction of the long-run benefits of the acquisition to the winner.

民國90年代初期，我國參照美、日私募之規定，正式引進私募制度。此後，企業得以選擇公開現金增資，或透過私募發行新股，來募集所需的營運資金。根據統計，民國94年以後，台灣的私募市場日趨成熟，私募逐漸成為企業最重要的籌資管道之一，特別是讓原先不能符合公開募集資格之公司，合法迅速取得資金。雖然私募之平均發行金額仍小於公開現金增資，但近年來私募件數平均都有超越公開現金增資之表現，顯示私募在資本募集市場的重要角色，也肯定其對於企業和經濟發展之正面功效。 過去文獻指出，美國之私募平均以折價發行，且有顯著正的宣告股價效果。針對不同樣本之特性，Wruck（1989）、Hertzel and Smith（1993）和Barclay, Holderness and Sheehan（2007）分別提出監督假說（monitoring hypothesis）、資訊不對稱假說（information asymmetry hypothesis）和自利假說（entrenchment hypothesis）解釋之。雖然我國之私募制度多參照美國而訂定，但法律架構和私募流程仍有相當程度的差異。因此，本研究將以上述三大假說為基礎，藉由樣本敘述統計和線性迴歸分析，探討我國上市上櫃公司私募之定價與宣告股價效果。 我們自公開資訊觀測站收集民國91年至98年7月底之私募股權樣本，扣除變數資料不全者，最後共有398筆，包含上市公司174筆，上櫃公司224筆。研究發現，我國私募多以折價發行。其中，特別股之折價幅度低於普通股，電子科技類普通股之折價幅度又高於普通股之平均。而且，根據迴歸結果，私募金額、私募比率和公司規模三個變數最能解釋我國私募之折溢價幅度，但並沒有傾向支持任一個私募假說。 至於宣告股價效果，我國私募董事會和股東會皆不顯著為正，且宣告股價效果的迴歸解釋力也偏低，只有股價淨值較具顯著性。探究其原因，可能是因為我國私募制度不同所致。依證交法之規定，私募股權需先經由董事會和股東會同意後，始得募集。然而，最後私募成功與否常與市況和發行公司能否找到適當投資人等密切相關。既然兩事件日都不能保證私募可以如期完成，我們也就無法預期投資人會對私募有明確迅速的反應。 / In the beginning of 2000, Taiwan’s Securities Transaction Law was amended to introduce the new way of financing- private placements. Since then public corporations are allowed to issue new securities either by public offerings and private placements. According to statistics, after 2005 private placements have become one of the most important funding sources for corporations, especially for those who are disqualified for public offerings. Although the average proceed of private placements is still relatively small, the number of private placements has already surpassed that of public offerings in recent years. This manifests the important role of private placements in building a sound financial market. Private placements in the U.S., despite selling at discounts, are associated with significant positive abnormal returns on the announcement date. With different sample characteristics, Wruck (1989), Hertzel and Smith (1993) and Barclay, Holderness and Sheehan (2007) suggest monitoring hypothesis, information asymmetry hypothesis and entrenchment hypothesis respectively. Our study is based with these three most accepted hypotheses and aims to give an insight in Taiwan’s private placement of equities for public corporations. I search the Market Observation Post System for all private placements from 2002 to July of 2009, and obtain a sample of 398 private equities with complete data. Empirical evidence shows that Taiwan’s private equities are selling at discounts as well and “proceeds of private equity”, “placement fraction” and “corporate size” are the three significant explanatory variables for discounts. However, all the results seem not to fully support any hypothesis as mentioned above. On the other hand, the announcement stock price effects on the board and shareholders’ meeting are insignificantly positive in Taiwan. The regressions on the announcement stock price returns also indicate low explanatory power with only “Tobin’s Q” variable being significant overall. This may be attributed to the legislation differences between U.S. and Taiwan. According to Taiwan’s Securities Transaction Law, private equities should be first approved by the board and shareholders’ meeting, but might not be a successful private equity placement due to market condition, lack of proper investors and others. As a result, we can’t expect investors would instantly, correctly respond to this resolution information on those announcement dates.

Esta pesquisa buscou investigar a anomalia dos accruals nos retornos de cinco países da América Latina (Argentina, Brasil, Chile, México e Peru), bem como observar se os aspectos institucionais impactaram nos retornos anormais de accruals dos países. Para tanto, foram analisadas séries temporais para cada país, agrupadas em carteiras de accruals e carteiras de setor, para os modelos CAPM, 3-fatores e 4-fatores, incluindo o fator accruals e observados os retornos anormais das séries, avaliando-os por meio da estatística GRS e pelas estatísticas de teste do procedimento de Fama e MacBeth. Em seguida, foram construídos modelos de dados em painel para o período de 2004 a 2017, em que as variáveis dependentes foram os retornos anormais de accruals, resultantes das séries temporais mensais de cada uma das empresas, e as variáveis independentes foram os fatores institucionais característicos dos países e as variáveis a nível de empresa. O estudo esperava que, se confirmados os retornos anormais de accruals nas séries temporais da América Latina, os fatores específicos de cada país contribuiriam para explicar as diferenças de retornos anormais existentes entre eles. Os resultados confirmaram a presença de retornos anormais em todos os países da amostra, em todos os modelos e o comportamento dos accruals explicou parte dos retornos. Além disso, as variáveis institucionais dos países estudados impactaram os retornos anormais de accruals. Por fim, esta pesquisa fornece evidências quanto a generalização da anomalia dos accruals, enriquecendo a literatura sobre países ainda pouco explorados e de importância econômica crescente, além de prover indícios sobre os efeitos dos aspectos institucionais na anomalia dos accruals na América Latina. / This research aimed to investigate accrual anomaly of returns from five countries in Latin America (Argentina, Brazil, Chile, Mexico and Peru), and to observe whether institucional factors impacted the accruals abnormal returns in these countries. For that purpose, time series for each country were built, and grouped in accruals and industry portfolios for Capital Asset Pricing Model (CAPM), 3-factor and 4-factor models, including the accrual factor (ACC). Abnormal returns were detected through the GRS statistics and the Fama and MacBeth procedure. Then, panel data models were used considering the period from 2004 to 2017, in which the dependent variables was the accrual abnormal returns resulted from the individual monthly series for each analyzed company; and the independent variables were the country-specific institutional factors and the company-level variables. Considering previous literature, in this study, it was expected that, if the accrual abnormal returns were confirmed in the time series from Latin America, the specific factors from each country would contribute to explain the differences between the returns. The results confirmed the presence of abnormal returns in every country from the sample and in all models, plus, the behavior from accruals partially explains returns. Furthermore, the institutional variables of countries influence the accruals abnormal returns. Finally, this research provides evidence over the generalization of accruals anomaly, contributing to literature on poorly studied, but economically relevant countries, besides providing signs regarding effects of institutional factors effects on the anomaly in Latin America

Using the event study methodology we found evidences of an abnormal return around the event. It was found that the abnormal return persists among the period from 2000 to 2010. Additionally, we verify that for the Brazilian market it is not possible to assign the effect of taxes the cause of the abnormal results. / Este estudo procura avaliar o comportamento do retorno das ações ao redor das datas ex-distribuição de capital no mercado acionário brasileiro. A partir da metodologia de estudo de eventos encontramos indícios da existência de um retorno anormal médio ao redor do evento. Constatou-se que o retorno anormal persiste do longo do período de 2000 até o fim de 2010. Adicionalmente verificamos que no caso brasileiro não é possível atribuir ao efeito dos impostos a presença do retorno anormal verificado.

The net debt to average share price ratio and the debt to asset ratio of a company impacts the decision for this restructuring process statistically significant. The announcement of a spinoff yields abnormal returns (AR) for the stockholders of the parent. The relative size of the spin and the financial leverage correlated with the AR positively, whereas the net debt per share and the return on asset negatively. Therefore, no direct wealth transfer from the debt holders of a company to the equity holders can be derived from these results. / Esta tese examina o valor gerado através de processos de spin-off durante o período compreendido entre 2002 e 2010. Os rácios da Dívida Líquida/Preço Médio das Acções e da Dívida/Activo de uma empresa reflectem impactos estatísticos significativos na decisão deste tipo de processos de reestruturação. Assim sendo, o anúncio e decisão de se proceder a um spin-off contribui para que seja gerado um retorno anormal) (RA) para os accionistas da empresa-mãe. O tamanho relativo do spin-off e a respectiva alavancagem financeira correlacionam-se positivamente com os RA, enquanto, por outro lado, a dívida líquida por acção e a rendibilidade líquida dos activos correlacionam-se negativamente. Deste modo, não é possível verificar uma transferência de riqueza dos detentores de títulos de dívida de uma empresa para os detentores de capital próprio.
