民國91年1月2日啟動交易的「興櫃市場」，提供投資者一個合法、安全及透明的未上市（櫃）股票交易市場，而依台灣證券交易所(TSEC)上市審查準則及櫃檯買中心(OTC)上櫃審查準則之規定欲申請初次申請上市（櫃）股票之公開發行公司，必先登錄興櫃股票，並掛牌交易達六個月以上，先熟悉市場交易規則及充分透明的資訊揭露，進而才有資格申請成為上市櫃公司。然興櫃市場是否具有「價格發現」機制，又影響其申請上市櫃(IPOs)股票蜜月現象因素為何，係本研究之探討重點。 本研究主要探討興櫃公司初次申請上市（櫃）(IPOs)股票蜜月現象及其影響因素，研究目的在於「暸解檢驗興櫃公司從興櫃登錄至申請上市（櫃）（IPOs）期間是否存在超額報酬，並從公司基本因素、公司於興櫃市場表現因素、公司上市（櫃）時條件因素、市場景氣與制度因素與公司治理因素等五大類，瞭解其對於IPOs蜜月現象的影響。此外，並以實際登錄興櫃公司申請上市櫃進度，從興櫃股票在登錄興櫃日、上市（櫃）送件日、上市（櫃）審議委員會通過日等三個不同時點的兩個超額報酬，相對於上市（櫃）審議委員會通過日至上市（櫃）掛牌日這段期間之超額報酬的影響。另解析個案公司SWOT分析結果，探討個案公司相對於其所面對外部環境之機會與威脅，以及公司內部環境所具備的優勢與劣勢等相關影響因素。 本研究運用複迴歸分析，得到實證結果發現興櫃申請上市(櫃)公司： 1.「登錄興櫃日至上市（櫃）送件日之超額報酬」主要與產（行）業別、興櫃交易天數、登錄興櫃日至上市（櫃）送件日之大盤漲幅、會計師事務所聲譽等因素有關。 2.「上市（櫃）送件日至審議委員會通過日之超額報酬」受到公司成立年數、興櫃交易天數、稅後EPS、登錄興櫃日至上市（櫃）送件日之大盤漲幅、上市（櫃）送件日至審議委員會通過日之大盤漲幅的影響。 3.「審議委員會通過日至上市(櫃)掛牌日收盤價之超額報酬」與產（行）業別、興櫃個股日平均成交金額、興櫃交易天數、中籤率、承銷價、登錄興櫃日至上市（櫃）送件日之大盤漲幅、上市（櫃）送件日至審議委員會通過日之大盤漲幅、審議委員會通過日至掛牌日收盤價之大盤漲幅、首五日無漲跌幅限制、會計師事務所聲譽有關。 4.「議定承銷價至上市(櫃)掛牌日收盤價之超額報酬」則是受到公司成立年數、興櫃交易天數、承銷價、稅後EPS、首五日無漲跌幅限制等變數的影響。 除上述影響因素外，個案分析興櫃申請上市櫃(IPOs)公司可發現若該公司在產業皆具有領導地位、產品當紅有競爭利基（如ＩＣ設計等）具有國際競爭力及成長潛力、掌握關鍵研發創新技術、營收或獲利不斷成長、有較高毛利率及稅後每股盈餘、部份有富爸爸資源支持及垂直整合從與外資青睞，從登錄興櫃經審議委員會到上市（櫃）掛牌皆有超額報酬現象。 / Emerging Stock Market, which was started the transaction on January 2, 2002, provides the investors a legitimate, safe and transparent stock transaction market of unlisted company. According to the listed examination criterion of TSEC and OTC, an initial public offerings (IPOs) company has to be listed and transacted on Emerging Stock Market for over than six months to be familiar with the transaction rule of market and disclose the information of the company fully transparently. Then it has the admissibility of applying to transfer to listed market. This thesis mainly explores the honeymoon effect of IPOs stock and its influence factors. The five purposes including: 1. To examine whether there is exceed return when an emerging company transferring to an IPOs company. 2. To discuss the influence to the exceed return of IPOs by the five group factors, including the company fundamental, the performance in Emerging Market, the conditions of the company at IPOs, the market situations and systems, and the company governance. 3. To discuss the influence to the exceed return of IPOs by the two time period factors between the three time points: listed day in the Emerging Market, the apply day to TSEC and OTC, and the day the application approved by Examination Committee of TSEC or OTC. 4. To give SWOT analysis (combined with five forces analysis) in the case studies to explore, of the target companies, the opportunities and threats of the external environment and the strengths and weakness of the internal environment. 5. To apply the exploration in Purpose 1, Purpose 2, and Purpose 3 to the target companies in the case studies. By using multiple regression model, we found the following results: 1. The exceed return from the listed day in Emerging Market to the apply day to TSEC or OTC is related to the industry, the days staying in Emerging Stock Market, the performance of TSEC index, and the reputations of accountant business offices. 2. The exceed return from the day applying to TSEC or OTC to the day the application approved by Examination Committee is related to the company age, the days a company staying in Emerging Stock Market, the EPS after tax, and the performance of TSEC index. 3. The exceed return from the day the application passed by Examination Committee to the closing price at listing day is related to the industry, the average amount of transaction in Emerging Stock Market, the days a company staying in Emerging Stock Market, the transaction lot size, the stock offering price, the performance of TSEC index, the 7% price limit has been cancelled under the new underwriting system in five trading days after IPO, the reputations of accountant business offices. 4. The exceed return from the IPOs price to the closing price at listing day is related to the company age, the days a company staying in Emerging Stock Market, the stock offering price, the EPS after tax, the 7% price limit has been cancelled under the new underwriting system in five trading days after IPO. Besides the above factors, we found, from the case studies, that IPO companies have the exceed return when they possess: the leadership in the industry, the international competitiveness and growth potential of their niche products, the key creative technology of R&D, the continuation growing of revenue and profit, the higher profit rate and the EPS after tax, the support of the parent group, and the foreign capital investors.

中國新上市公司（Initial Public Offerings，以下簡稱IPO）上市後經營績效大幅衰退之現象時有所聞，IPO績效變化不僅影響投資者的利益，也攸關轉型經濟過程中，中國證券市場能否有效引導社會資源的配置。本研究調查2001年至2005年間，在中國深圳以及上海交易所A股市場IPO公司經營績效變化以及可能原因，延伸討論保薦制度及政治關聯對前述現象的影響。首先測試樣本公司上市前後經營績效之差異，並調整同業平均數。實證結果指出，上市後兩年ROA及ROE(無論是否調整產業因素)皆不如上市前兩年，杜邦分析發現獲利能力衰退是造成財務績效衰退的主因。 保薦制度於2004年2月1日正式施行，藉由提升保薦人及保薦機構的執業水準，以建立市場約束機制。本研究依保薦制度實施及政治關聯分別分組，採用分群組T檢定與Wilcoxon做差異分析。實證結果顯示保薦制度下IPO公司上市前的各項財務績效較佳，顯示其能篩選體質較好公司上市；而上市後績效衰退的情形也較為趨緩，中介機構制衡機制有所發揮。政治關聯度低的低國有股公司在上市前的各項財務績效指標較高國有股公司好，推論政治關聯可能影響上市機會，使其上市前需極大化自身績效；相對而言，上市後較難維持績效。 進一步分析績效衰退原因，本研究比較各期間IPO公司各項應計數變化。實證結果顯示。整體而言上市後總應計、流動應計數、營業相關應計數以IPO當年呈倒V型，有上市後反轉的現象，並與經營活動現金流量變動呈反向變動，推論與盈餘操縱有關；保薦制度的在應計數反轉現象沒有顯著抑止效果，而政治關聯度低的IPO公司亦沒有顯著操縱應計數的現象以極大化上市前經營績效。最後，代理問題探討中結果顯示，董監持股變動以及大股東持股變動與績效衰退顯著相關，符合利益一致假說。 / The article investigates whether there is a significant change in financial performance of firms after they went to public for the period between 2001 and 2005 in China A –share market. First, we use ROA and ROE as main performance index. The results indicate a significant decline in ROA and ROE. Following Du Pont framework, return on sales is the most important reason about the decline. Second, we find under new Sponsor’s System, IPO firms had better perfomanace before they went public and they suffered less declined after IPO. We also find the low political connection firms maximize financial performance before they went public to win the IPO opportunity, and they hardly maintain operating performance. At last, we examine the reason for financial performance decline. We compared the change between accruals and operating cashflow the period of IPO for inspecting wether earnings management existed. The empirical results indicate IPO firms maximize accruls when IPO.This study also indicates a significant correlation between post-IPO performance and agency problem.

Pirminių viešų siūlymų reikšmė yra itin aktuali finansų krizės nuniokotose rinkose, nes pirmieji vieši vertybinių popierių siūlymai yra alternatyva įprastiniam skolinimuisi ir galėtų išjudinti stagnacijos apimtas rinkas. Jie padėtų kompanijoms pritraukti lėšas bei plėtoti verslus, pritraukiant finansinius išteklius ir nukreipiant juos pelningoms investicijoms ar kitiems poreikiams tenkinti. Sėkmingas pirminis viešas siūlymas kompanijos suteikia ne tik galimybę pritraukti gana dideles garantuotas lėšas, bet ir stabiliai augančias akcijų kainas biržose.

IPO helps companies to raise funds and develop their business by attracting financial resources and using them for profitable investments or other needs. A successful initial public offering not only provides the ability to raise enough funds, but also guarantees high, but steadily rising share prices on stock exchanges. After a successful initial public offering, the company has even greater possibilities for the routine borrowing and the greater confidence in foreign markets. The object of this paper work – initial prices of IPO‘s in the Baltic market. The goal of this paper work – research and evaluation of the Initial price Efficienty, factors, which have influence on it in the Baltic IPO market.

Background: A public offering or "Initial Public Offering" means that a company is transferred from being unlisted to trading on a stock exchange. When a company is listed, the company needs to establish a prospectus. This document is meant to give potential investors information about the operations in the company with both historical financial data and more descriptive information. The prospectus should therefore contain all necessary information needed to make a well-founded assessment about the IPO. Historically IPOs have tended to overperform in the short term and have an underperformance in the long run compared with already listed companies. Purpose: The purpose of the study was to identify the general return patterns for IPOs in Sweden in both short-term and in the long run. The study also aims to investigate whether the company's prospectus published in connection with the IPO can explain these yield patterns. Methodology: The general return patterns have been calculated using the Buy and Hold Abnormal Return (BHAR) and Cumulative Abnormal Return (CAR) methods. The raw returns shown by the IPOs have been adjusted to the chosen reference index to determine whether an over- or underperformance has taken place. In addition, several multiple regressions have been conducted to determine whether selected variables can explain the abnormal return shown by IPOs. Conclusion: The study results shows that the initial return on the first day of the 2007-2014 period was an average of 2.82% for the study's selection of 45 public offerings from Stockholmsbörsen and First North. The IPOs showed a negative trend with an underperformance in the first three months. The result for the short term is thus not consistent with previous research in IPOs. In the long run, however, the study's selection shows an underperformance of -12.85% measured with BHAR and -24.13% with CAR. This result is consistent with previous studies in other markets. Furthermore, only one of the selected variables, the initial return, could to some extent (16.8%) explain the abnormal return for the first month. The other variables were not statistically significant in any of the studied periods. / Bakgrund: En börsintroduktion eller "Initial Public Offering" innebär att ett företag övergår från att vara onoterad till att handlas på en aktiebörs. I samband med att ett företag börsnoteras behöver företaget upprätta ett prospekt. Detta dokument ska ge potentiella investerare information om verksamheten av både beskrivande kvalitet och historiska finansiella data som kan kvantifieras av investeraren. Ett prospekt bör således innehålla all nödvändig information för att göra en välgrundad bedömning. Vidare har börsintroduktioner historiskt visat att dessa tenderar att överprestera på kort sikt och underpresterar på lång sikt jämfört med redan börsnoterade företag. Syfte: Syftet med studien var att identifiera generella avkastningsmönster för börsintroduktioner på kort- och lång sikt i Sverige. Studien ämnar även att undersöka om företagets prospekt som publiceras i samband med börsintroduktionen kan förklara dessa avkastningsmönster. Metod: De generella avkastningsmönstrena har beräknats med hjälp av metoden Buy and Hold Abnormal Return (BHAR) och Cumulative Abnormal Return (CAR). Avkastningen som börsintroduktionerna uppvisar har justerats till valt referensindex för att avgöra huruvida en över- eller underprestation har skett. Vidare har flertal multipla regressioner genomförts för att fastställa om utvalda variabler kan förklara den abnormala avkastningen som börsintroduktioner uppvisar. Slutsats: Studiens resultat visar att den initiala avkastningen första dagen under perioden 2007–2014 var i genomsnitt 2,82% för studiens urval på 45 stycken börsintroduktioner på Stockholmsbörsen och First North. Börsintroduktionerna visade på en negativ trend med en underprestation de första tre månaderna. Resultatet för kort sikt överensstämmer således inte med tidigare forskning inom börsintroduktioner. På lång sikt däremot uppvisar studiens urval en underavkastning på -12,85% mätt med BHAR och -24,13% med CAR. Detta resultat överensstämmer med tidigare studier på andra marknader. Vidare kunde endast en av de utvalda variablerna, den initiala avkastningen, till en viss grad (16,8%) förklara den abnormala avkastningen på en månad. De andra variablerna var inte statistiskt signifikanta i någon av undersökningsperioderna.

Les pays de la zone OHADA observent, depuis une dizaine d’années, un accroissement significatif des opérations de capital-investissement. Les perspectives économiques encourageantes, la relative stabilité politique dans la région ainsi que les prévisions démographiques font de la zone OHADA une cible de premier choix pour les fonds d’investissement, qui y trouvent de formidables opportunités d’investissement et de croissance. Cette nouvelle dynamique nous appelle à nous interroger sur la faculté du droit OHADA à répondre aux exigences juridiques exprimées par ces nouveaux acteurs économiques lors de la conduite de leurs opérations. Cette thèse se propose d’analyser, dans une perspective comparative avec le droit français, les principaux enjeux juridiques du capital-investissement en droit OHADA. Ainsi, y seront étudiés les outils juridiques de prise de participation, la gestion des sociétés cibles, notamment à travers la pratique des pactes d’actionnaires, et enfin, les modalités de sortie de l’investissement. L’objectif annoncé est de déceler les forces et les faiblesses du régime actuel du droit OHADA à l’épreuve des exigences du capital-investissement / In the last decade, the OHADA countries have seen a significant increase in private equity transactions. The OHADA region’s economic outlook, relative political stability and projected population growth make the region of prime interest to investment funds due to tremendous growth and investment opportunities. This new dynamic makes it important to consider OHADA law’s ability to meet the legal requirements of private equity funds in structuring and conducting their operations.This thesis (i) analyses the main legal issues for private equity under OHADA law and (ii) compares the handling of such issues under OHADA law with their handling under French law. As such, this thesis addresses the legal instruments for taking ownership interests, management rules for target companies (including shareholder agreements), and exit strategies. The objective of such analysis is to identify the strengths and weaknesses of the current OHADA law regime from a private equity perspective

O presente trabalho buscou investigar, sob a perspectiva da Teoria da Sinalização, o papel certificador dos fundos de Private Equity e Venture Capital (PE/VC) sobre a qualidade das empresas estreantes na BM&FBovespa (IPOs). Para isso, propôs-se um estudo de evento visando constatar a existência de retornos anormais acumulados (proxy para qualidade dos IPOs) em carteiras de investimentos compostas por ações provenientes dos IPOs realizados na BM&FBovespa, no período de janeiro de 2004 a dezembro de 2007. As hipóteses do trabalho foram verificadas por meio de três procedimentos distintos: teste de médias, método CAPM e regressões CAR. Os resultados dos testes de médias indicaram que os IPOs de empresas investidas por fundos de PE/VC apresentaram desempenhos de curto, médio e longo prazo (até 5 anos) superiores e estatisticamente significantes em relação às empresas não investidas. Além disso, os resultados demonstraram que quanto maior a participação dos fundos de PE/VC na empresa investida, melhor o desempenho de longo prazo. Os resultados do método CAPM indicaram que os retornos observados dos IPOs foram inferiores aos retornos esperados, dado o nível de risco assumido. As regressões CAR verificaram se a presença de fundos de PE/VC explica retornos anormais positivos dos IPOs, após controle de outros fatores. As evidências encontradas sugerem que a presença de fundos de PE/VC nas empresas estreantes na BM&FBovespa possui efeito positivo sobre os retornos anormais acumulados dos IPOs e, quanto maior a participação acionária detida pelo fundo de PE/VC na empresa, no momento imediatamente anterior ao IPO, maiores os retornos anormais acumulados de longo prazo. Em geral, os retornos das amostras analisadas foram inferiores ao desempenho do índice Ibovespa, podendo ser um reflexo da crise financeira mundial, com maior impacto sobre empresas com histórico recente na bolsa (IPOs), em relação às empresas tradicionais (blue chips) que integram o Ibovespa. / This study investigated, under the perspective of Signaling Theory, the certifier role of Private Equity and Venture Capital investments (PE/VC) on the quality of initial public offerings (IPOs) at BM&FBovespa. It was proposed an event study in order to examine the existence of cumulative abnormal returns (proxy for IPOs quality) in portfolios composed of stocks from the IPOs occurred on BM&FBovespa, from January 2004 to December 2007. The hypotheses of this study were verified by three different procedures: test for equality of means, CAPM method and CAR regressions. The tests for equality of means suggested that the companies that received investments of PE/VC, before the IPOs, had statistical significant short, medium and long-term performances (up to 5 years) higher than non-invested companies. Besides that, the results showed that the higher the equity PE/VC held in the companies, before the IPO, better the long-term yield. The CAPM method indicated that the observed returns were lower than the expected returns, given the level of risk assumed. CAR regressions examined whether the presence of PE/VC explains positive abnormal returns of the IPOs, after controlling for other factors. The evidence suggests that the presence of PE/VC has positive effect on the cumulative abnormal returns on the IPOs, and the higher the equity held by the PE/VC in the firm, immediately before the IPO, the greater the long-term cumulative abnormal returns. In general, the returns of the samples were below Ibovespa index, which may be a reflection of the global financial crisis, with greater impact on companies with recent history in the stock market (IPOs), compared to traditional firms (blue chips) that integrate Ibovespa.

Cette thèse s’interesse à l’étude des effets des sociétés de Capital-Investissement (SCI) sur la performance des introductions en bourse. La démarche suivie pour argumenter cette thèse nous a conduits, dans une première partie, à justifier notre positionnement théorique et à définir nos hypothèses de recherche. Cette étape nous a orientée vers l’analyse des caractéristiques des introductions en bourse et l’analyse du rôle des SCI notamment sur le marché des introductions en bourse. Nous avons construit une argumentation autour du rôle des SCI en matière de résolution des asyémtries informationnelles caractérisant les sociétés introduites en bourse. Les SCI, étant dotées d’une capacité à concevoir des contrats, d’un réseau de connaissance et d’une expertise, pourraient atténuer les conflits d’agence et émettre un signal positif sur le marché d’IPOs. En revanche, ces sociétés pourraient se retrouver face au problème de sélection adverse au moment de la décision d’investissement et/ou adopter un comportement opportuniste pour servir leurs intérêts. La vérification empirique de cette problèmatique est développée dans la deuxième partie de notre thèse. Elle consiste à comparer la performance à court et à long terme des sociétés financées de celles non financées par CI, ensuite analyser cette performance en foction de l’affiliation institutionnelle des SCI et enfin, expliquer cette performance en fonction de la réputation des SCI et des stratégies d’intermédiation de celles-ci, notamment la syndication, le financement séquentiel et la distribution des droits aux cash-flows et au contrôle / In this dissertation, it is tried to understand the effects of Venture Capital Firms (VCF) on the performance of VC-backed listed companies in France. To do this research, we try to develop, in the first part, theoretical framework and define research hypothesis. This part leads us to examine characteristics of initial public offerings (IPOs) and the role of venture capitalists particularly in conducting an IPO. We develop the argument around the role of VCF in resolving informational problems, characteristics of IPO’s market. A VCF, being specialists to draw up contract with entrepreneurs and possessing expertise and knowledge network, could diminish conflicts of interests and certify IPOs. However, these firms could run a problem of adverse selection and/or adopt opportunistic behaviour to serve their own interests. The empirical validation of this problem is dealt with in second part of this dissertation. It consists, in first place, to compare performance of VC backing IPOs to Non-VC backing IPOs. In second place, we determine the relation between the performance of VC backing IPOs and the institutional affiliation of VCF. In last part, we test explanatory power of reputation of VCF and their mechanisms of intermediation, particularly, syndication, staged financing and distribution of cash-flows and control rights

Die vorliegende Studie entstand, um die langfristige Renditeentwicklung polnischer Aktien nach Börseneinführungen und Kapitalerhöhungen in den Jahren 1994-2008 zu untersuchen. Ein besonderes Augenmerk richtet sich dabei auf die Erkennung und Analyse der performancerelevanten Unternehmenseigenschaften sowie auf die Erklärung der festgestellten Marktanomalien mit Hilfe ausgewählter Modellansätze. Die empirischen Analysen wurden aus dem Blickwinkel eines Kleininvestors durchgeführt, wodurch die meisten Ergebnisse, neben dem wissenschaftlichen Wert, eine hohe Praxisrelevanz besitzen. Die Untersuchung von insgesamt 263 Börseneinführungen ergab, dass die Emissionsrenditen der meisten Aktien zwar signifikant positiv waren, längerfristig bauten sie sich aber ab. Am Ende des 36-sten Notierungsmonats wiesen sie insgesamt eine starke Underperformance auf. Dabei entwickelten sich die langfristigen marktbereinigten IPO-Renditen in den 90-er Jahren wesentlich schlechter, als nach der Jahrhundertwende. Die Analyse des Kursverhaltens nach 157 Kapitalerhöhungen durch Aktien- und Bezugsrechtsemissionen zeigte, dass innerhalb der dreijährigen Halteperiode die Performance der betrachteten Stichprobe von der Rendite des Gesamtmarktes nur geringfügig abweichte. Dabei entwickelten sich die Kurse von Aktien der kleineren Firmen wesentlich schlechter, als die Aktienkurse der hochkapitalisierten Unternehmen. / This study investigates the long-term stock return after initial public offerings and seasoned equity offerings occurred between 1994 and 2008. A particular attention is being paid to the identification and analysis of performance-relevant issuing firm characteristics and the explanation of the identified market anomalies by means of the preselected explanatory models. Since the empirical study was carried out from the small investor’s perspective, the majority of the obtained results provide not only a considerable scientific value, but also a strong relevance to the actual practice. The study examined 263 IPOs of common stocks and found an overwhelmingly positive initial return. However, this return vanished gradually on the long run, resulting in a high overall underperformance in 36 months after the first listing. In this respect, it is remarkable that the long-term returns of the IPO-stocks issued in the 1990s proved considerably lower than of those placed after 2000. The examination of the long-term stock price behaviour after 157 SEOs reveals only a tiny difference between the performance of the sample and the overall market return. Noteworthy is however the fact that equity issues conducted by smaller firms led usually to significantly poorer stock performance, than when equity was offered by large capitalized companies.

本研究旨在探討我國生醫產業公開說明書之資訊揭露程度對初次公開發行 (IPO, initial public offering)定價效率及次級市場投資人信念異質性程度之影響。當初級市場認購人間資訊不對稱程度越大時，IPO價值之事前不確定性越高。為均衡各交易參與者之利益，發行人與承銷商將主動提升公開說明書之資訊揭露程度，以制定適當的IPO折價幅度、維持承銷商合理的承銷風險與報酬，並協助認購人適切評定IPO之價值。異質信念觀點強調次級市場投資人對企業價值看法之歧異程度越大，將導致IPO蜜月期報酬之異常現象。本研究預期若無形資產密集度越高，IPO事前不確定性越大，則IPO折價幅度越大，並預期公開說明書之資訊揭露程度將改變無形資產密集度對折價幅度之影響程度。此外，本研究預期，生醫產業IPO案件之無形資產密集度、公開說明書之資訊揭露程度及者配售情形均可能影響投資人信念異質性，進而影響掛牌初期之成交價量表現。 本研究參考國外證券主管機關之無形資產資訊揭露規範，自行建立資訊揭露指標，系統性地衡量我國生醫產業公開說明書之資訊揭露程度，並以多元迴歸分析檢測假說。實證結果顯示，我國生醫產業IPO案件之無形資產密集度對IPO折價幅度存在顯著正向影響；公開說明書之資訊揭露程度改變無形資產密集度對折價幅度之影響程度；發行人之無形資產密集度、公開說明書資訊揭露程度及初級市場配售情形皆影響掛牌初期之投資人信念異質性及價格震盪幅度。研究結果證實公開說明書之資訊揭露提供預期效益，及初級與次級市場間之資訊相互流通、交易行為相互連動之關聯性。 / This research examines how the disclosure level of prospectus influences the efficiency of IPO (initial public offering) pricing in the primary market and the degree of divergence of opinions in the secondary market. The literature of IPO underpricing suggests that ex ante uncertainty due to information asymmetry has a positive impact on IPO discount and voluntary disclosure of prospectuses may reduce the uncertainty level. This research hypothesizes that, for biotechnology companies, a greater disclosure level of prospectuses would lower the impact of intensity of intangibles on IPO discount. Further, this research hypothesizes a relation between the pricing efficiency in primary market and the level of divergence of opinions in secondary market. The empirical results from regression analyses of hand-collected data show that, for biotechnology IPOs, the disclosure level of prospectuses reduces the impact of the intensity of intangibles on IPO discount. In addition, the intensity of intangibles, disclosure level of prospectuses, and trading behaviors in the primary market have an effect on the degree of divergence of opinions in the secondary market. In sum, this research evidences the expected benefits of the increased level of voluntary disclosure of prospectuses for biotechnology IPOs.
