我国股票IPO发行方式改革问题探讨

我国股票发行方式在市场化和法制化的道路上历尽波折,目前停留在半市场化的累计投标询价制度上.为解决IPO抑价和监管的行政化色彩问题,维护股票市场良好的投资秩序,股票发行方式改革必须坚持保护中小投资者利益这一基本原则,以求改善中国股市的生态环境.     

我国新股市场IPO抑价研究

股票市场是证券市场的重要组成部分,过高的抑价会造成一二级市场发展不平衡,从而加大股市系统性风险。本文作者在分析影响新股发行抑价的四个因素之后,对发行企业,投资者,承销商,监管机关在新股发行中的博弈行为进行研究,指出我国股市IPO抑价问题主要由股市制度缺陷引起,投资缺乏其他获利来源,然后提出政策建议。     

基于创业板市场的承销商声誉与超募现象研究

本文以2009-2014年在我国创业板市场上市的387家企业为研究样本,分析了承销商声誉对于上市公司超募现象的影响,通过分析发现我国的承销商声誉对企业的资金超募具有正向的影响,这表明声誉越高的承销商能够带给公司更多的超募资金。为了进一步降低创业板市场的投机现象,需要进一步完善我国股票发行制度,使承销商声誉能够对IPO超募形成约束效应。     

我国证券承销商声誉与IPO企业质量关系的实证分析

本文利用中国证券发行市场上的数据资料检验了我国承销商声誉与IP0企业质量之间的关系，实证分析的结果显示“认证中介理论”和Chemmanur-Fulghieri模型所表明的承销商声誉与IPO企业质量之间正相关的关系在我国证券发行市场中被扭曲，因此投资者通过承销商的声誉等级来区分发行企业质量的信息甄别机制在我国证券发行市场基本上不存在。这种情形致使我国承销商的信息生产功能和“认证中介”职能严重缺位，这是导致我国证券发行市场信息不对称问题严重、投资者“逆向选择行为”普遍、低质量发行企业充斥市场的一个重要原因。本文认为，管理层改变这种状况的政策取向应包括IPO企业筛选机制的市场化、承销服务费用的市场化、推进和完善“保荐人制度”以及促进承销商股权结构多元化和分散化等几个方面的内容。     

我国创业板IPO抑价现状分析

本文以新一轮新股发行制度改革为背景,选取股票上市首日交易机制完善后在创业板上市的公司为样本,对我国创业板IPO抑价最新特征进行分析,并结合国内外IPO抑价理论和我国创业板自身特征,尝试给出原因和相关政策建议。     

浅析我国A股市场IPO抑价现象

本文研究发现,我国A股市场存在显著的IPO抑价现象,即股票IPO发行价格显著低于其上市价格。本文指出了IPO抑价现象对证券市场有效运行的负面影响,并深入分析了我国IPO抑价现象存在的原因。综合考虑我国A股市场的现状,本文对提高A股市场股票定价效率提出了相关建议。     

二级市场投机对A股IPO抑价率影响的实证分析

本文在借鉴相关研究的基础上,将影响IPO抑价的因素分为一级市场因素以及二级市场因素两类,并选取2009年10月—2011年12月A股上市的全部股票,将在主板和中小板上市的股票作为一个样本,在创业板上市股票作为另一样本,分别进行实证研究。结果证明,投机—泡沫假说能够有效地解释主创两板的IPO抑价现象中。其中,创业板股票发行市盈率与IPO抑价显著正相关,证明了二级市场的过度投机在抑价中起到了主导作用,而主板及中小板股票发行市盈率与IPO抑价不存在显著相关性,不能证明二级市场的低效是主板IPO抑价的主要原因。     

上海A股市场IPO抑价现象实证研究

IPO抑价是发展中国家的一个普遍现象。本文通过对352只A股股票进行多元回归分析,发现我国股市存在IPO抑价现象,平均抑价幅度为126%,并认为较低中签率、较小发行规模、较低发行市盈率、较高首日换手率、上市间隔时间短并在市场走势较好时发行上市的新股抑价程度较高     

Does reputation of sponsors matter in IPO? Evidence from Hong Kong

Contrary to other markets where underwriters perform a combined role of underwriting and sponsoring in an Initial Public Offering (IPO), IPO issuers in Hong Kong must appoint at least one sponsor in addition to the underwriters. The splitting of the single role of underwriters into two separate ones offers an ideal setting to disentangle the effects of the two roles and to examine which of the two roles—sponsor or underwriter—is more important in explaining IPO underpricing and initial volatility in the Hong Kong equity market. Interestingly, our findings provide supportive evidence that the sponsor reputation does matter in an IPO and it is even more significant than the underwriter reputation in explaining the IPO underpricing phenomenon. Given the recent high-tech fervor, our research goes deeper to examine specifically the role of sponsors on high-tech firms, with results indicating that the reliance on sponsors is higher for traditional issuers than for technology firms. We further discover that sponsors and underwriters are playing substitution roles rather than complementary roles. In order to examine the regulatory policy impact, our research also compares the role of IPO sponsors before and after the launch of the new sponsor regulatory regime in 2013. The empirical findings lend support to our argument that after the launch of the new regulations, public awareness of sponsors is raised, respect towards more reputable sponsor increases, and thus, the role of sponsors becomes more important than before.     

IPO抑价与证券市场制度变迁

IPO抑价是股票市场一个普遍存在的一个现象,我国也不例外。国外的理论重在研究IPO抑价的原因,且这些理论都是建立在市场有效的前提条件之上的,用这些理论解释我国IPO抑价率过高的情况不是特别合适。本文就我国证券市场各个阶段定价方式和发行制度的特征及各阶段IPO抑价率的情况做一简要分析,并针对IPO抑价存在的问题提出对策建议。     

Signaling and initial public offerings: The use and impact of the lockup period

To reduce information asymmetries for potential investors considering investment in an IPO venture, owners can signal the firm's longer-term viability and quality in several ways. The lockup period, is one signal that can be offered. We investigated the lockup period of a sample of 640 ventures going through the IPO and find that a longer lockup period acts as a substitute signal to venture capital (VC) and prestigious underwriter backing. Furthermore, we find that ventures which have a going concern issue can reduce the amount of underpricing at the time of the IPO by accepting a longer lockup period.     

Ownership structure,insider behavior,and IPO performance of SMEs in China

This paper examines the drivers of IPO performance of 783 SMEs in China between 2009 and 2012 that were listed on the SME and Growth Enterprise Boards. The study finds that firms that had prior venture capital (VC) investment did not perform better than those that did not. Among VC-invested firms, ventures (1) with strong VC control rights relative to those of the largest block shareholder, (2) with former ownership affiliation between the VC and the underwriter, and (3) that paid higher IPO fees had a negative long-term performance. The negative relationship between VC-underwriter ownership affiliation and long-term performance decreases as the reputation of the underwriter increases.     

Organizational Virtue and Stakeholder Interdependence: An Empirical Examination of Financial Intermediaries and IPO Firms

Organizational virtue orientation (OVO), an organizational-level construct, refers to the integrated set of beliefs and values that support ethical character traits and virtuous behaviors. To advance the study of organizational virtue, we examine OVO in firms making their initial public offerings (IPOs), with respect to key external stakeholders that serve as financial intermediaries (i.e., venture capital firms and underwriting banks). Drawing on stakeholder and resource dependence theories, we argue that mutual interdependencies occur between financial intermediaries and IPO firms such that venture capital firms’ ownership levels and underwriter reputation are positively associated with the selection of more virtuous IPO firms. We also argue for the moderating relationship of IPO firm age on these main relationships; since IPO firms have more history and information availability, less importance will be placed on OVO in the selection process. In support of our hypotheses, the results of this study suggest the organizational virtue of IPO firms influences the selection decisions of financial intermediaries by reflecting positively on these key stakeholders to improve legitimacy and reputation.     

承销费用、政府定价管制与 IPO 抑价--来自中国首次公开发行公司的经验证据

选择2001年11月1日至2012年12月31日的中国A股IPO公司为研究样本,分析承销费用与IPO抑价之间的关系及其在政府定价管制程度不同情况下对承销费用与IPO抑价关系的影响。结果显示,承销费用与IPO抑价呈正相关关系;而政府定价管制程度的提高会削弱承销费用与IPO抑价之间的正相关关系,甚至会使其转向负相关关系。     

Strategic behavior of insiders in initial underpricing and long-run underperformance

We study strategic behavior of insiders in ChiNext IPOs. Since traditional initial underpricing is not appropriate due to the jawbone P/E ratio approach and maximum initial return cap we propose two alternative measures. We identify a significantly positive relationship between insiders' shareholdings and initial underpricing. With no discretion on IPO offer price, the insiders implement earnings management to maintain higher stock prices induced by regulatory changes and high market demand and to facilitate selling their unlocked shares after lockup expiration. We confirm a negative impact from insiders' share sales on long-term performance but don't observe a dramatic underperformance as documented.     

Underpricing in new equity listings: A conceptual re-appraisal

This paper appraises the existing approaches used to measure the underpricing of Initial Public Offerings (IPOs). The conceptual problems surrounding the measurement of IPO underpricing are noted to be significant and suggest that underpricing costs and returns may need to be evaluated with reference to the particular characteristics of individual offerings. For example, details of the number of primary shares on offer, the effect on corporate control of listing, the information effects resulting from listing, the liquidity of shares pre-offer, the impact of speculative activity on post-listing firm value and, finally, the actual dating of an IPO may all need to be considered. In short, the existing measures suggested for IPO underpricing do not allow managers/owners in IPO firms or investors in IPO stocks to assess, unequivocally, the respective costs and returns from underpricing in such issues.The authors would like to acknowledge the helpful comments of an anonymous reviewer.     

风险投资对创业板市场IPO抑价的影响

通过对218家在创业板上市公司首次公开发行当天股价上涨现象进行研究,结果表明在创业板推出初期上市的公司存在严重的IPO抑价。中国创业板近70%的公司有风险资本背景,但是创业企业的风险资本对抑价水平的影响不显著,上市公司本身的特点和财务业绩因素对IPO抑价影响也不显著。中国创业板市场IPO抑价严重的原因是创业板市场运行机制不成熟,二级股票市场投机情况严重。另外,付市盈率、中签率、换手率等对IPO抑价水平影响显著。
