A股、H股新股初始收益率比较研究

本文借鉴IPO已有的研究成果，分别对上海A股、香港H股的新股初始收益率进行了实证研究，探讨了企业选择A股或H股发行上市所导致的两个市场的不同反应及其真正动因。实证结果表明，上海A股市场较香港H股市场具有更高的新股初始收益率，但呈逐年递减趋势；A股市场的新股初始收益率与中签率、发行价、上市首日开盘价、上市首日换手率显著相关，而H股市场的新股初始收益率则与净利润增长率、香港恒生指数显著相关。     

股权分置改革前后A股IPO初始收益率的比较研究

本文采用股权分置改革前后的新股样本数据,对影响我国A股初始收益率的相关因素展开实证分析。研究发现．股权分置和发行管制是造成股权分置改革前A股IPO市场高初始收益率的根本原因,而在股权分置改革后．由于发行继续受到严格管制和投资者旧有定价理念及盈利模式的延续,新股的初始收益率仍然存在继续高企的制度基础和市场条件。因此,在股权分置改革后,管理层应进一步推进发行监管制度改革,实现股票供给市场化。

承销商托市与新股折价

引言新股首次公开发行(initial public offerings,IPOs)的高初始收益率(即上市首日交易价格高于发行价格)现象自20世纪70年代以来一直是财务学界研究的一个重要领域。我国的证券市场长期以来也一直续演着“新股不败”的神话，每一次新股发行往往伴随着巨额的申购资金和上市后的惊人涨幅。……     

IPO首日超额收益率影响因素分析

本文对2000年至2012年期间上海证券交易所新股IPO首日的超额收益率进行了总体分析,发现沪市新股IPO首日超额收益率均值水平高达109.7%。明显高于纽约、香港和新加坡证券市场。基于沪市的高超额收益率水平及属性结构特征,本文从公司自身因素、市场因素和制度因素三个层面构建了IPO首日超额收益率影响因素指标体系,并采用因子分析和多元回归分析相结合的方法对IPO首日超额收益率的影响因素进行了分析。分析发现,规模因子、上市市场成熟度因子和收益性因子对新股首日收盘收益率起负向影响作用,而上市公司成长能力因子则起正向影响作用;保荐制审核方式比通道制方式下的新股首日超额收益率小,网下询价、网上定价发行方式则比其他发行方式首日收盘收益率大。     

我国IPO定价的实证分析

新股发行(IPO, Initial PublicOffering)定价是股票发行业务中的核心环节,定价是否合理不仅关系到发行人、投资者与承销商的切身利益,而且关系到股票市场资源配置功能的发挥。判断发行定价是否合理的主要标准是,发行价的确定是否以预期的二级市场价格作为定价基础。新股发行抑价是指新股发行定价存在低估现象(Underpricing),一般证券市场上都存在这一现象,根据一个对32个国家(地区)样本区间的统计,股票上市首日平均收益率达27.86%,这说明新股发行价格和新股上市价格本身还是有所不同。从统计数据看,欧美发达国家成熟市场的新股发行抑价程…     

投资银行声誉与新股抑价关系实证研究

一、引言 根据有效市场理论,如果新股发行定价是根据市场的真实信息确定的,那么上市时就不应出现超额收益率,因为市场上的套利行为会使得超额收益率消失.但国内外大量研究表明新股在上市首日总会产生超额收益,这一异象吸引了学界的关注,并提出了种种解释.主流观点将该种现象称为"新股抑价",即认为二级市场是充分有效的,一级市场严重的信息不对称造成了新股发行价被低估,从而使其在上市后出现超额收益.     

IPO二级市场高溢价影响因素分析

针对新股二级市场高溢价现象,从一级发行市场和二级市场两个方向选择了若干解释变量,并通过主成分分析法从一级发行市场变量中提取了4个因子,结合二级市场解释变量对近3年上海证券交易所IPO的158家公司上市后的超常收益进行了实证分析。发现机构申购报价、每股净资产、发行比以及次新股板块收益率4个因素是导致新股高溢价的主要原因,即机构在申购时的行为和普通投资者的非理性行为加剧了新股高溢价现象。     

基于横截面多元回归的我国IPO首日换手行为分析

在我国特殊的T+1交易制度下,我国的IPO首日换手率偏高.分析发现,导致我国IPO股票发生高换手率的因素有:初始收益率、市场特征、承销商声誉、发行公司年龄和初始发行规模.并发现,如果公司的发行规模大于1.5亿元人民币时,换手行为与承销商的声誉不相关.应加强对不正常的新股首日高换手的监管,防范动机不良的交易者的违法乱市行为,以规范我国股市的良性发展.

Mossin's Theorem Given Random Initial Wealth

The purpose of this article is to reexamine Mossin's Theorem under random initial wealth. Conditions necessary and sufficient for Mossin's Theorem depend on the stochastic dependence between risks. The correlation coefficient, however, is not an adequate measure of stochastic dependence in the general expected‐utility model, and so other notions of dependence are used to investigate Mossin's Theorem. The inadequacy of the correlation coefficient is illustrated with two counterexamples. Then, using notions of positive and negative dependence measures, we provide necessary and sufficient conditions for a generalized Mossin Theorem to hold. In addition, a generalized Mossin Theorem is interpreted using the notion of a mean preserving spread made popular by Rothschild and Stiglitz (1970) . Given a fair premium and dependent stochastic conditions, we show that an individual can obtain a final wealth distribution with less weight in its tails by selecting less than or more than full insurance.     

Initial credit ratings and earnings management

Credit rating agencies assert that they rely on financial information provided by issuers and that they value rating stability as well as accuracy. In an environment where rating agencies depend on issuer-reported information and are reluctant to adjust ratings promptly, managers of issuing firms can utilize the discretion afforded by GAAP to obtain the most favorable credit ratings. Consistent with our expectations, we find that current accruals are unusually positive and high around initial credit ratings. The increase in abnormally high accruals leading up to the initial credit rating year is followed by a reversal in the subsequent years. Multivariate regression analyses suggest that accounting accruals, abnormal current accruals in particular, are significantly positively related to initial credit ratings after controlling for several issue- and issuer-related characteristics indicative of default risk. Our results are robust to additional tests that account for endogeneity between credit ratings and earnings management, adjust for performance, and account for firms issuing debt and equity simultaneously.     

Analyst Following of Initial Public Offerings

We examine data on analyst following for a sample of initial public offerings completed between 1975 and 1987 to see how they relate to three well-documented IPO anomalies. We find that higher underpricing leads to increased analyst following. Analysts are overoptimistic about the earnings potential and long term growth prospects of recent IPOs. More firms complete IPOs when analysts are particularly optimistic about the growth prospects of recent IPOs. In the long run, IPOs have better stock performance when analysts ascribe low growth potential rather than high growth potential. These results suggest that the anomalies may be partially driven by overoptimism.     

The Variability of IPO Initial Returns

The monthly volatility of IPO initial returns is substantial, fluctuates dramatically over time, and is considerably larger during “hot” IPO markets. Consistent with IPO theory, the volatility of initial returns is higher for firms that are more difficult to value because of higher information asymmetry. Our findings highlight underwriters’ difficulty in valuing companies characterized by high uncertainty, and raise serious questions about the efficacy of the traditional firm‐commitment IPO process. One implication of our results is that alternate mechanisms, such as auctions, could be beneficial for firms that value price discovery over the auxiliary services provided by underwriters.     

Initial Offer Precision and M&A Outcomes

Building on recent research in social psychology, this paper analyzes the link between the precision of initial cash offers and mergers and acquisition (M&A) outcomes. About one‐half of the offers are made at the precision of one or five dollars per share, while an additional one‐third are made at the precision of a half dollar or one quarter. The practice of making offers at round price‐per‐share levels is associated with a higher purchase price for target shares and a lower probability of deal completion.     

Initial Public Offerings: CFO Perceptions

We examine four issues pertaining to initial public offerings (IPOs) using a survey of 438 chief financial officers (CFOs). First, why do firms go public? Second, is CFO sentiment stationary across bear and bull markets? Third, what concerns CFOs about going public? Fourth, do CFO perceptions correlate with returns? Results support funding for growth and liquidity as the primary reasons for IPOs. CFO sentiment is generally stationary in pre‐ and post‐bubble years. Managers are concerned with the direct costs of going public, such as underwriting fees, as well as indirect costs. We find a negative relation between a focus on immediate growth and long‐term abnormal returns.     

Initial Public Offerings and Underwriter Reputation

This paper examined the returns earned by subscribing to initial public offerings of equity (IPOs). Rock (1986) suggests that IPO returns are required by uninformed investors as compensation for the risk of trading against superior information. We show that IPOs with more informed investor capital require higher returns. The marketing underwriter's reputation reveals the expected level of “informed” activity. Prestigious underwriters are associated with lower risk offerings. With less risk there is less incentive to acquire information and fewer informed investors. Consequently, prestigious underwriters are associated with IPOs that have lower returns.     

安倍经济学的初期效果与未来制约

2013年7月21日，日本参议院第23届选举结果揭晓，由日本首相安倍晋三领军的自民党与其联合执政的公明党获得了参议院的过半席位，从而终结了日本众参两院的“扭曲国会”局面。安倍由此成为6年来首位控制国会参众两院的日本首相，这将使安倍内阁推行自己的“安倍经济学”时更加具有执行力和连贯性。本文拟在深入分析安倍经济学已经产生积极与消极效果的基础上，重点探讨日本未来影响安倍经济学成效的主要因素。
