上市动机、投资者情绪与首次公开募股市场收益

文章以发行人筹资收益最大化为假设,对市场热季周期下发行人、承销商与投资人三者之间的博弈过程以及投资者情绪对首次公开募股(IPO)市场定价的影响机制进行研究.研究结果表明,发行人最优发行数量小于市场需求数量、承销商定价低于市场需求价格的目的在于确保发行成功和获取日后收益;投资者高亢的投资情绪可以对IPO市场短期收益正偏和长期收益负偏成为普遍现象进行解释.     

Does market misvaluation help explain share market long‐run underperformance following a seasoned equity issue?

We examine the relation between pre‐seasoned equity offering (SEO) announcement date misvaluation and long‐run post‐SEO performance for a large sample of Australian SEOs made between 1993 and 2001. Our study is motivated by inconsistent findings across countries with respect to the SEO long‐run underperformance anomaly first documented in the USA, inconclusive findings with respect to the hypothesis that managers exploit market misvaluation when timing equity issues, and a recent Australian Stock Exchange proposal to loosen SEO regulation. We find SEO firms underperform common share market benchmarks for up to 5 years after the announcement. Using a residual income valuation method, we show that this underperformance is related to pre‐announcement date misvaluation. An unexpected result is that underperformance and misvaluation are more severe for private placements than rights issues. Institutional factors unique to the Australian setting, particularly the large number of smaller loss‐making firms among private placement issuers, appear to explain the poorer performance of placement firms. Our results are robust to various measurement methods and assumptions, and demonstrate the importance of researching SEO performance in alternative institutional settings.     

Is the Abnormal Post-IPO Underperformance Really Abnormal? The Evidence from CEE Emerging Markets

Using sorting procedures and cross-sectional tests, we investigate the long-run post-IPO performance and its sources in the Central and Eastern European (CEE) markets. We examine over 1100 stocks from 11 CEE countries for the period 2002–2014. We find that “old stocks” perform significantly better than “young stocks”, but only when the market beta is the sole risk factor considered. After accounting for the size and value effects, the IPO firms perform neither better nor worse than non-issuing companies. The sources of the initial low B/M ratios of debuting companies may lie in time-varying financial quality. The market newcomers are financially healthier than their older counterparts. However, over 2–5 years the fundamentals deteriorate and the financial standing regresses to the mean.     

Intended Use of Proceeds,Underwriter Quality and the Long‐run Performance of SEOs in the UK

We document that prospectus disclosure of (i) the motives for a seasoned equity offering, and (ii) the choice of underwriter explain the long‐run performance of equity issuers in the UK. Firms citing investment needs show no abnormal performance after the offering and have higher investment rates post‐issue compared to the period before the offering. Issuers that state general corporate purposes and recapitalisation motives underperform, have similar investment rates pre‐ and post‐issue, and their leverage tends to increase after the offering. Further, consistent with the certifying role of underwriters, equity issues underwritten by high‐quality brokers show no evidence of post‐issue abnormal returns, but offerings taken public by low‐quality underwriters exhibit negative abnormal performance. Together, our results document the significant role that prospectus information on the intended use of offering proceeds and on the underwriter play in predicting issuers post‐offering performance in the UK.     

The performance of stocks that are reverse split

An unusually high number of Nasdaq National Market stocks were reverse split following the decline in Nasdaq prices in the year 2000. We test whether these splits were driven by the overall market decline. We find that the performance of stocks with reverse splits in poor overall stock market conditions is better (less negative) than that in good market conditions, and that the differences in performance appear three to five months after the split. This suggests that the longer-term outcomes of reverse stock splits are associated with the market environment at the time of the split. In view of this, changes that Nasdaq made to relax some of its listing standards are well justified.

高溢价发行下的创业板收益分布研究

股票的发行、上市、流通在时间上先后继起。良好的发行与交易制度能够引导建立一个资本市场投资者共赢的利益分配格局,但是中国创业板新股高溢价发行的存在却打破了这个格局。当前资本市场收益分布的特征是:初始收益高溢价和长期弱势并存,对两者间相关程度的细化实证分析表明,高溢价发行是导致收益分布格局失衡的主要原因。进一步探究高溢价的源头所在,则可追溯至现行发行制度的诸多弊端;而进一步追问收益分配失衡的影响结果,则显而可见资本市场公平与效率的不对称。因此,从根本上治理与完善发行制度,是均衡创业板各参与者的利益分配,促进创业板可持续健康发展的重要之策。     

Diamonds in the rough: The value of scouting for early-stage funding

IPOs of small early-stage companies have largely declined in the last few decades. Governments and exchanges have responded with new regulations to encourage access for small firms to public markets. Critics caution, however, that lower standards for going public may be worse for investors. In this paper, we document one exchange’s approach to encourage small IPOs: founders establish shell companies through which to scout and promote funding of early-stage companies. We find that founders earn compensatory returns for their search role, and that the average long-term performance of these companies is similar to that of small conventional IPOs, underscoring that conventional IPOs may fail to identify or screen companies of similar quality asymmetrically. Consistent with prior literature on small IPOs, the long-term post-IPO performance of both the conventional and alternative funding processes are highly right-skewed and poor, on average, but not statistically different.     

Pension funds and IPO pricing. Evidence from a quasi-experiment

We exploit a quasi-experiment arising from the government-forced changes to the assets under management and investment policy of the Polish pension funds. We test whether this new regulation and its resultant demand shock on the investors' side, leads to changes in the IPO pricing and the subsequent stock's performance. We report material and a statistically significant decrease in the IPO proceeds (IPO size) in the post-treatment period equal to over 107 million PLN (34 million USD). We find no empirical evidence that the treatment had a significant effect on the first-day IPO underpricing or on the long-term underperformance. We conclude that the demand shock resulting from the pension system reform that primarily aimed at solving fiscal problems effectively eliminated the so-called ‘pension premium’ of higher IPO valuations. Thus, it indirectly impaired companies' power of raising money in the public stock market. Furthermore, we report a decrease in the average first-day IPO returns among big issuers that is consistent with the book building literature.     

Stock market anomalies and baseball cards

Baseball cards exhibit anomalies that are analogous to those that are documented in financial markets, namely, momentum, price drift in the direction of past fundamental performance, and initial public offering (IPO) underperformance. Momentum is higher among active players than retired players, and among newer sets than older sets. Regarding IPO underperformance, we find that newly issued rookie cards underperform newly issued cards of veteran players, and that newly issued sets underperform older sets. The results are broadly consistent with models of slow information diffusion and short-selling constraints.
