新上市股的長期績效優於市場,但相較於五年未發行新股的對照公司則較差,而在市場空頭時期上市的股票績效卻相對較佳.和未發行新股的對照公司相較,股票的年報酬率變化呈現碗狀的趨勢,在上市後的營運績效有下滑的現象,隱含投資人有過度樂觀的情形.新股發行效果存在,即新上市股在上市五年內對預期報酬率都有負的影響.此效果和規模效果,市價淨值效果同時存在而無法取

[pt] Em uma oferta inicial de ações, uma das dificuldades dos investidores é avaliar que preço pagar pela ação lançada. Para diminuir tal dificuldade, a Comissão de Valores Imobiliários exige que as empresas emissoras apresentem demonstrativos financeiros dos últimos três anos de operações. Esta dissertação avalia a precisão desses demonstrativos financeiros, através de uma amostra de 67 emissões de ações na Bovespa entre 2002 e 2007. A análise dos dados mostra que as emissões com um único banco coordenador apresentam uma maior incidência de rubricas discriminatórias, que aumentam os lucros acumulados. Tais rubricas aparecem mais frequentemente em demonstrativos no formato pró-forma, que não impõem uma responsabilidade legal sobre os auditores, consistente com a hipótese de que as rubricas discricionárias têm por finalidade inflar os lucros contábeis. / [en] Investors face the challenge to value the price of a share during na ipo. With the purpose of improving their ability, the Brazilian Securities and Exchange Commission (CVM) demands companies to present financial statements for the last three years of continuing operations. This dissertation assesses the quality of these financial statements using a sample of 67 IPOs that took place at São Paulo Stock Exchange between 2002 and 2007. The analysis of the prospectuses gives us evidence that IPOs with only one investment bank on their syndicate present higher discretionary accruals and by consequence, reported earnings. The use of discretionary accruals is more common in pro forma financial statements which exempt auditing companies from legal responsibility and therefore enhance the hypothesis that discretionary accruals are used in order to inflate earnings.

Bakgrund: De senaste åren har en stark underprissättningstrend observerats i det ökande antalet börsnoteringar, vilket har skapat ett starkt investerarintresse. En stor del av dessa nyintroducerade bolag är småbolag, varav de flesta noteras på mindre handelsplatsformer, så kallade MTF:er. MTF:en Aktietorget introducerade flest företag till den svenska aktiemarknaden 2010-2014, varför detta har valts till studiens undersökningsområde.Tidigare studier har bevisat att det finns en hög volatilitet i nyintroduktioner och småbolag, vilket i finansiella sammanhang betyder att en sådan investering är mer riskfylld. Dock saknas liknande studier på downside volatilitet, alltså risken för förlust. Denna studie ämnar därför att jämföra den traditionellt riskjusterade avkastningen i form av sharpekvoten, mot avkastningen justerad för downside risk, den så kallade sortinokvoten. Detta nyare mått på risk är en del av den postmoderna portföljteorin, som tar hänsyn till en mer förlustaversiv investerare. Syfte: Syftet med denna uppsats är att analysera den riskjusterade avkastningen i nynoteringar på Aktietorget för att jämföra med etablerade bolag på OMX Stockholm. Den riskjusterade avkastningen beräknas genom sharpe-respektive sortinokvoten och jämförs sedan för att undersöka eventuella skillnader i bedömningen av aktiernas prestation. Genomförande: Uppsatsen är en eventstudie med deduktiv ansats. Undersökningen har inkluderat nynoteringar på Aktietorget mellan 2010-2014 och jämförelseaktier består av branschindex från OMXSPI.Den riskjusterade avkastningen har beräknats via modifierade kvoter. Samband mellan sharpe-respektive sortinokvoten har undersökts genom icke-parametrisk rangordningskorrelation. Slutsats: Studien kan inte bevisa en signifikant abnormal avkastning i nynoteringar på Aktietorget, men observerar en genomsnittlig överavkastning upp till en månad. De riskjusterade kvoterna har mycket stark rangordningskorrelation, vilket innebär att studiens resultat inte kan motivera en fortsatt användning av sortinokvoten. / Background: In recent years, a strong underpricing trend has been observed in the increasing number of IPOs, which has created a strong investor interest. A large part of these IPO companies are small firms, most of which are listed on smaller trading venues, known as MTFs. The MTF Aktietorget introduced most companies to the Swedish stock market during 2010-2014, so it has been chosen as the area for this research.Previous studies have shown that there is high volatility in new introductions and small companies, which in financial terms means that such an investment contains more risk. However, similar studies on downside risk are lacking. This study therefore aims to compare the traditional risk-adjusted return in the form of the sharpe ratio, against the return adjusted for downside risk, the so-called sortino ratio. This newer measure of risk is part of the postmodern portfolio theory, which takes into account a more loss-aversive investor. Purpose: The purpose of this paper is to analyze the risk-adjusted return in IPOs on Aktietorget and compare it with the return of established companies on OMX Stockholm. The risk-adjusted return is calculated by the sharpe and sortino ratios, respectively, and are later compared with each other to investigate possible differences in the estimation of performance for the stocks. Methodology: This paper is an event study with a deductive approach. The study has included IPOs on Aktietorget between 2010-2014 and comparative stocks, consisted of industry index from OMXSPI.The risk-adjusted return has been calculated using modified ratios and the relationship between the sharp and sortino ratios has been investigated by non-parametric ranking correlations. Conclusion: The study can't prove any significant abnormal return in IPOs on Aktietorget, but observes an average excess return of up to one month. The risk-adjusted ratios have very strong rank correlation, thus empirical results can't motivate the continued use of the sortino ratio.

Les années récentes ont témoigné un manque de dynamisme des marchés boursiers qui a poussé un nombre croissant d'investisseurs à se tourner vers les marchés privés, notamment le private equity. Ce manuscrit aborde des thématiques qui caractérisent les mutations que connait le private equity aujourd'hui: une recherche de liquidité relative, une quête de rendements supérieurs dans de nouveaux marchés et une stabilité des ressources humaines qui restent un vecteur de communication important lors des levées de fonds auprès des investisseurs.Le premier essai de cette thèse examine l'impact de l'introduction en bourse des véhicules de private equity sur leurs performances et montre que cette recherche de liquidité induit une diminution significative des performances réalisées. Le deuxième essai traite de la performance du private equity dans les marchés émergents et montre que la réussite de ces investissements est liée à la distance géographique et à la proximité culturelle entre les firmes de private equity et les entreprises financées.Enfin, le dernier essai de cette thèse examine l'importance du capital humain pour les firmes de private equity et montre que la mobilité des managers détériore les performances réalisées. / Recent years have witnessed a lack of momentum in equity markets that has driven a growing number of investors to turn to private markets, including private equity.This manuscript addresses research questions that characterize the changes that private equity is experiencing today: a search for relative liquidity, a quest for superior returns in new markets, and a stability in human capital, which remains an important vector of communication during fundraising.The first dissertation of this thesis examines the impact of the public listing of private equity vehicles on their performance and shows that exposure to liquidity induces significantly lower realized performances.The second dissertation examines the performance of private equity in emerging markets and shows that the success of these investments is related to the geographic distance and the cultural proximity between private equity firms and the investee companies.Finally, the last dissertation of this thesis examines the importance of human capital for private equity firms and shows that manager mobility deteriorates performance.

Studien genomfördes med syftet att undersöka varför företag tenderar att vara nöjda med sin börsintroduktion trots att den varit underprissatt, vilket bidrar till flertalet negativa konsekvenser. Studien undersöker om underprissättningen kan bero på brist av värderingskompetens eller om företagen själva har incitament till att underprissätta sin börsintroduktion och har tagit hänsyn till handelsplatserna Aktietorget och First North under åren 2013 – 2015. Studien baseras på en kvantitativ metod och har genomförts med inhämtning av sekundärdata samt en enkätundersökning för att undersöka hur företagen resonerar inför en börsintroduktion. Enkätfrågorna har kopplats till befintlig teori samt övriga variabler som torde vara viktiga för företagen inför en börsintroduktion och har sedan analyserats med hjälp av uni-, bi- och multivariat analys. Slutsatsen är att den viktigaste variabeln för ett företag som står inför en börsintroduktion på Aktietorget eller First North är att säkerställa en fulltecknad emission. För att lyckas med det påvisar analysen att företag kan ha incitament till att underprissätta sin egen börsintroduktion. Vidare påvisar analysen att företagen inte strävar efter studiens nämnda incitamentsteorier i någon stor grad och att något signifikant samband mellan teorivariabler och initial avkastning inte finns för studiens respondenter. Författarna tolkar därför incitamentsteorierna som positiva sidoeffekter av att en underprissättning sker och inte som något företagen eftersträvar i första hand vid en börsintroduktion på Aktietorget och First North. / This study investigates why corporates tend to be satisfied with their IPO although it has been underpriced, which contributes to several negative consequences. The study investigates if this depends on the lack of valuation expertise or if the enterprises have incentives to underprice their own IPO. This study was conducted on the Swedish Stock Exchanges Aktietorget and First North during 2013 – 2015. This study takes a quantitative approach and was conducted by using secondary data and a survey to investigate which variables are the most important for an enterprise that is staging an IPO. The survey questions were linked to existing theory and other variables that should be important for an enterprise that is staging an IPO. The results was analyzed through a uni-, bi- and multivariate analysis. The study concludes that the most important variable for an enterprise that is staging an IPO on Aktietorget or First North, is to ensure a fully subscribed stock issue. To be able to ensure this, an enterprise could have incentives to underprice their own IPO. Furthermore, the study conclude that the enterprises does not strive for this study’s described incentive theories in any large extent, and that any significant relation between these variables and underpricing do not exist for this study’s respondents. The authors of this study therefore interprets these theories as positive side effects of an underpricing and not something enterprises that is facing an IPO strive for primarily on Aktietorget and First North.

No. of bitstreams: 1 Jose Milton Almeida da Silva.pdf: 951427 bytes, checksum: 2eb314059433ac66640426ac17114465 (MD5) Previous issue date: 2009-10-05 / The central goal of this research was to increase the debating about efficacy from rules, legal actions and Corporate governance to protect the non qualified minority shareholders in the Brazilian IPOs (Initial Public Offering) programs. The theme has showed growing interest, because the number of personal investors and the Bovespa s (São Paulo Stock Exchange) IPO market has been in progress strongly. The event study was the methodology used to measure the abnormal returns in the portfolio s samples with between 23 and 98 shares from 106 IPOs going public in 2004-07, using de market price from January, 2004 to June, 2008. Further, four statistic tests were applied to detect if the speculative bubble dynamic affected the Bovespa from January, 1999 to June, 2008. The empiric results from event study evidenced the overpricing phenomenon measured from the offering price to the market price at the end of the first day of trading estimated between 4,80% and 9,26%, and a underpricing phenomenon in the sequel. The cumulative average abnormal returns, ruled out of the first day return, achieved -11,52% at the end of the 6º month, -16,60% at the end of the 12º month and -35,74% at the end of the 24º month, presented a underperfomance phenomenon with economic and statistic significance, widely documented by the academy, specially on the north American capital market. The empiric results from four statistic tests showed, with statistic significance, that speculative bubble dynamic affected the Ibovespa (Index of São Paulo Stock Exchange) in the period from January, 1999 to June, 2008. Thus, evidences were found of the minority shareholders that bought shares in the Bovespa s IPOs programs in the studied period were induced by market anomalies to overpay the share s portfolios. Consequently, the research suggests that actions to improve the rules, legal actions and Corporate governance is necessary to protect of the non qualified minority shareholders in the Brazilian capital market / Esta pesquisa teve como objetivo central ampliar as discussões quanto à eficácia das normas, procedimentos e Governança Corporativa na proteção dos acionistas minoritários não qualificados nos processos de IPO s (Initial Public Offering) ou abertura de capital das companhias no mercado de capitais brasileiro. O tema apresenta importância crescente em face do recente aumento do número de investidores individuais e do forte incremento do mercado de IPO s na Bolsa de Valores de São Paulo (Bovespa). A metodologia empregada foi um estudo de evento para a identificação da presença de retornos anormais em carteiras compostas por uma amostra entre 23 e 98 ações de um total de 106 IPO s realizados na Bovespa entre 2004 e 2007, abrangendo as cotações das ações no período entre janeiro de 2004 e junho de 2008. Também foram realizados quatro testes estatísticos visando detectar indícios da presença da dinâmica de bolha especulativa na Bovespa no período entre janeiro de 1999 e junho de 2008. Os resultados empíricos do estudo de evento demonstraram evidências de sobre-valorização nos preços das ações no primeiro dia de negociação, com retornos anormais entre 4,80% e 9,26%, seguida de significativas quedas nas cotações subseqüentes. Os retornos anormais médios acumulados, excluído o retorno do 1° dia, atingiram -11,52% no final do 6º mês, -16,60% no final do 12º mês e -35,74% no final do 24º mês, evidenciando relevantes perdas de valor das carteiras analisadas no período, tanto em termos econômicos quanto em nível de significância estatística, caracterizando o fenômeno da underperformance, amplamente documentado pela academia, notadamente no mercado de capitais norte-americano. Os resultados dos testes estatísticos demonstraram indícios, com significância estatística, da presença da dinâmica de bolha especulativa na formação do Índice da Bolsa de Valores de São Paulo (Ibovespa) no período entre janeiro de 1999 e junho de 2008. Desse modo, foram encontradas evidências de que os acionistas minoritários que participaram dos processos de IPO s na Bovespa no período estudado foram induzidos, por anomalias de mercado, ao pagamento de valores acima dos preços justos das carteiras de ações. Como conseqüência, a pesquisa sugere a necessidade do aperfeiçoamento dos mecanismos de proteção dos acionistas minoritários não qualificados no mercado de capitais brasileiro

本研究探討台灣新上市股票是否有超額報酬之存在，並進一步探討超額報酬與其影響因素之關係：是否因為內部人持股比例高低，公司最近三年平均每股盈餘，負債比例高低，承銷價格高低，公司總資產大小，公司最近三年淨利變化，上市之後一年之內是否辦理現金增資而有所差異。本研究主要探討新上市公司，其新上市短期與長期異常報酬的解釋因素。 / This sutdy mainly employs empirical methodology. The sample period convers from 1987 to 1995, including 195 samples. The unerpricing regress against EPS (earnings per share), average earning growth rate, debt/equity ratio, firm's size , changes in ownership structure, seasoned new issues within one year subsequent to the IPO (dummy variable), and lottery rate. The findings indicate that the underpricing significantly (95% significant level) correlates with EPS, firm's size, and lottery rate.

近年來，我國政府大力推動海外企業來台上市，成效亮眼。在這股熱潮下，為了解海外企業第一上市新股和第二上市台灣存託憑證於我國資本市場掛牌後的表現，本研究針對2009年四月至2010年十二月間，外國與本國發行人在台灣證券交易所新上市之股票和台灣存託憑證進行實證分析。除檢定其是否存在異常報酬外，並綜合過往文獻、相關法令規範及迴歸分析結果，探討影響其異常報酬的可能原因。本研究主要發現如下： （1）國內外企業在台新上市股票及台灣存託憑證均具有顯著的期初異常報酬，其高低依序為－海外企業第一上市新股、國內企業新上市股票、海外企業第二上市台灣存託憑證。 （2）台灣存託憑證期初異常報酬的成因並非來自於承銷價格的低估，而是來自於投資人對於蜜月行情的過度反應。其主要證據為－平均達3%的發行溢價、蜜月期結束後顯著為負的累積異常報酬、及對期初異常報酬最具影響力的示範效果因子。 （3）國內企業在台新上市股票期初異常報酬的成因主要來自於承銷商與發行公司資訊不對稱所造成的承銷價格低估。其主要證據為－新股上市後穩定且接近1.5%的累積異常報酬、及對期初異常報酬最具影響力的折價幅度因子。 （4）海外企業來台第一上市新股異常報酬的成因可能部分來自於發行公司與投資人資訊不對稱所造成的承銷價格低估；部分則可能來自於投資人對蜜月行情的過度反應。其主要證據為－蜜月期結束後為負的累積異常報酬、及海外企業來台第一上市新股與國內新上市股票的合併資料迴歸中，群體效果、中籤率與海外第一上市名目變數等顯著影響因子的間接支持。 / This study attempts to investigate the different patterns of the abnormal returns of Taiwan listings by foreign issuers and IPOs by domestic issuers, for the period from April, 2009 through December, 2010. Of particular interest is to examine the determinants of the abnormal returns. The major findings of the study are as the follows: (1)Empirical results indicate that all Taiwan listing stocks, including IPOs by foreign and domestic issuers and TDRs, have significant abnormal initial returns. Among them, IPOs by foreign issuers show the highest abnormal initial returns while TDRs show the lowest. (2)Evidences like the negative CARs, the average 3% premium of TDR issuance and the demonstration effect suggest that investor overreaction could be a major factor contributing to TDRs’ significant abnormal initial returns. (3)Evidences also suggest the under-pricing by the better-informed underwriters may cause significant abnormal initial returns of IPOs by domestic issuers. The IPO discount is discussed as an in-depth demonstration. (4)The study assumes that the significant abnormal initial returns of IPOs by foreign issuers partly result from the under-pricing as a signal to attract investors, and partly result from investor overreaction.

The investigation is a result of the companies that in fact responded to the third version of the Survey on Corporate Governance in Brazil, previously conducted in 2005 and 2007. Analysis of adherence to BM&FBovespa’s corporate governance levels show a significantly greater adherence of the PE/VC backed companies in higher listing levels. Particular characteristics of the corporate governance of companies are detailed in an attempt to determine whether the clear advantage found in the comparison among the premium listing levels extends to other issues. The findings show significant differences in certain areas, i.e. processes of the board of directors, formation of committees, external auditor, shareholders rights, disclosure and compensation of officers and directors, which can be explained by the previous relationship of the backed enterprise, the PE/VC investor and the term sheet agreed upon between the parties.
