我国IPO询价制度实施效果研究

本文运用均值检验与逐步回归等实证分析工具,对我国IPO询价制度的实施效果进行了检验与研究.结果显示,目前我国的IPO询价制度并未使IPO效率获得大幅提升,IPO的首日与首周平均收益率仍处于较高水平.询价过程缺乏信息激励与甄别是影响询价制度实施效果的主要因素.IPO发行改革的方向是正确的,但询价制度仍需要进一步完善.     

英国的非公开权益资本和风险投资

英国是欧洲风险投资和非公开权益资本的发源地。在欧洲国家中,英国的风险投资和非公开权益资本起步最早,发展也最快。从1979年算起,英国风险资本投资额和非公开权益资本增长了100多倍。2005年,在欧洲的风险投资市场上,英国的风险资本总额占欧洲风险投资额的40￣50%,在欧洲是当仁不让的“大哥大”,在世界范围内仅次于美国。本篇文章主要介绍了风险投资(VentureCapital,VC)及非公开权益资本(PrivateEquity,PE)的最新概念和从属关系以及英国的风险投资及非公开权益资本的历史、结构、规模、投资趋势、投资阶段、投资领域、地理特征、知名风险企业、投资表现等,以此从数据和分析的角度使中国的风险投资领域及非公开权益资本领域的从业人员以借鉴、启迪的作用。     

How do investment patterns of independent and captive private equity funds differ? Evidence from Germany

Empirical literature emphasizes a positive contribution of private equity investors, which results from their combined provision of capital, monitoring, and management support. The aim of this study is to show that these previous results, which are based mostly on the analysis of US independent closed-end private equity funds, cannot be generalized since the private equity industry should not be treated as homogenous. We argue that it is necessary to distinguish between different types of private equity providers because their differing governance structures, strategic goals and experiences have a decisive influence on their value adding activities. The results of this study—which uses a data set of 179 German private equity-backed companies—are consistent with the conjecture that independent and corporate private equity providers tend to have a more pronounced role in corporate governance and monitoring of the companies they finance, than bank-dependent and governmental funds which often serve only as bridge investors.      

我国基金选股选时能力实证分析

本文运用西方基金绩效评价中较为常见的选股选时能力模型及其FF3改进模型对我国证券投资基金进行实证研究,在处理过程中考虑了不同取样频率和不同样本区间的影响.研究结果表明:(1)我国基金只存在很小程度的选股能力,而基本不存在选时能力,更没有基金同时具有选时能力和选股能力;(2)多因素改进模型与原模型相比显著提高了解释能力,说明在可能的情况下应尽可能使用多因素模型;(3)加快取样频率后基金表现出更强一些的选股能力,但在各年度内基金的选股能力有所差异.     

我国开放式基金的证券选择和市场时机把握能力研究

运用参数检验方法对我国42只股票型开放式基金的证券选择和市场时机把握能力进行了分年度检验,结果发现,开放式基金在2003年具有较强的证券选择能力,但不具备市场时机把握能力,在2004年上半年显示出了一定的市场时机把握能力,却从总体上表现出负向证券选择能力.基于2003年的基金年报分析显示,开放式基金在对未来市场趋势的预测上存在明显的"羊群行为".     

Venture capital trusts and the expiration of IPO lock-up provisions

Venture capital trusts (VCTs) were introduced to provide private equity capital for small expanding companies and to promote innovation. Investors in initial public offerings are rewarded with tax relief on the cost of lock-up provisions to stabilize the market. This paper examines the market reaction and trading activity around the expiration of lock-up provisions of 148 VCTs listed on the London Stock Exchange from 1995 to 2006. Downward-sloping demand curve theory suggests that an increased supply of VCT shares at the expiry date could shift their value to a new equilibrium at a lower price. Supporting this prediction, we document evidence of negative abnormal returns as well as permanent increases in the price discount relative to net asset value and trading volumes at and around the expiries of the required holding periods of VCTs. In addition, less negative abnormal returns, lower abnormal discounts and lower abnormal trading volumes are associated with VCTs that invest in AIM-listed companies due to lower information asymmetry, that experience lower prior performance due to a less pronounced disposition effect, and that are subject to a shorter lock-up horizon or are offering more generous tax benefits.     

SPAC merger announcement returns and subsequent performance

Special purpose acquisition companies (SPACs) are created to raise capital and then find non-listed operating companies with which to merge. While most of the extant research has focused on SPAC initial public offerings, we study what happens when SPACs announce business combinations. Our analysis of 236 ‘deSPACs’ completed between January 2012 and June 2021 in the United States documents an average short-term announcement return of +7.4% and a 1-year abnormal return of −14.1% (−18.0% over 2 years) for public investors beginning from the merger announcement. Short-term returns decrease with longer times from initial public offering until announcement.     

Tactical Asset Allocation and Stock Issuance in the Korean Stock Market

Stock issuance predicts future stock returns in the Korean market. This creates profitable trading opportunities. Abnormal returns exist in the zero-cost portfolio that short the firms issuing large numbers of shares and longs those issuing small numbers of shares. Their average abnormal return is 12 percent per annum, which is highly significant even after controlling for market, size, value, and momentum factors as well as transaction costs. The authors suggest the possibility of fixed costs in equity market timing. Only the sizable benefit from market timing over fixed costs motivates firms to increase net equity shares.     

The institutional determinants of private equity involvement in business groups—The case of Africa

This study examines the governance attributes of post-IPO (initial public offering) retained ownership of private equity in business group constituent firms in contrast to their unaffiliated counterparts, in 202 newly listed firms in 22 emerging African economies. We adopt an actor centered institutional-theoretic perspective in rationalizing institutional voids and the advantages of maintained governance by both business angels (BA) and venture capital (VC) private equity. Our findings reveal private equity retain higher post-IPO ownership in business group constituents compared to unaffiliated firms and that this is inversely moderated in the context of improving institutional quality – where this is particularly strong in case of foreign VC as opposed to domestic VC or BA. Our result adds to the literature on multifocal corporate governance mechanisms and the institutional determinants of private equity investment.
