How regulatory changes affect IPO underpricing in China

This paper examines the underpricing of IPOs in the Chinese A-share market during the period 1992–2006. Since its inception, the Chinese IPO market has transformed from a tightly-controlled system to a more market-oriented system. Reforms include the abolishment of listing quotas and fixed issue price determination; allowing for more market participation in IPO pricing. The regulatory changes of Chinese IPO market, though improving over time, actually are not monotonic. The regulatory framework started from over-restrictive to over-unrestrictive, then fine-tuned with additional restrictions. This study documents the regulatory reforms during the sample period and investigates how these regulatory changes affect IPO underpricing in China. During this period, we find that Chinese IPOs exhibit a huge underpricing. The size of the underpricing, however, decreases over the sample period. This study further finds that the IPO pricing method before the regulatory changes, which was based on a fixed P/E ratio pre-determined by the regulators, contributed significantly to the IPO underpricing in China. After adopting a series of regulatory reforms allowing underwriters discretion in the determination of issue price, this regulatory underpricing component vanishes. This study has policy implications in demonstrating the impacts of regulatory frameworks on IPO underpricing.     

Foreign vs. domestic listing: An entrepreneurial decision

In this paper, we use a unique hand-collected dataset to analyze stock listing as an entrepreneurial decision. By comparing mainland Chinese entrepreneurial firms listed in Hong Kong with the same type of firms opting for a domestic listing on the Shenzhen second board market, we argue that the decision to list on a particular stock exchange is a question of entrepreneurial signaling, and often a trade-off between short-term financial considerations and the entrepreneur's pursuit of long-term benefits.     

IPO定价与公司内含价值——基于常山药业的案例研究

如何对IPO公司准确定价是学术界和实务界广泛争议的热点话题。IPO定价准确性的评价依赖于对公司内含价值的判断，选择不同的标准确定公司的内含价值会得出IP0定价过高或过低的不同结论。本文应用可比公司法对常山药业的内含价值进行估计，使用四种可比公司乘数计算的结果表明公司实际发行价格高于公司内含价值，这意味着公司的发行价格存在一定程度的高估现象。与同期证券分析师对常山药业发行价格预测的平均估价水平相比，结果发现多数证券分析师由于过度乐观而高估公司内含价值。本文研究结果表明可比公司法具有计算简单、可操作性强等特点，不仅有助于一级市场中不同投资者对IP0公司的内含价值做出合理的估计，而且可以为二级市场交易中小投资者形成正确的投资决策提供依据，减少超额投资损失。     

Detection of Financial Time Series Turning Points: A New CUSUM Approach Applied to IPO Cycles

This paper presents a new Cumulative Sum approach for the detection of turning points in financial time series that are subject to cyclical mean level and volatility regime shifts. The new CUSUM approach is applied to the problem of detecting turning points in hot issue markets for Initial Public Offerings (IPOs), thus providing a multi-dimensional characterization of states of the IPO cycle.     

IPO share allocation and conflicts of interest

The underwriter of an IPO has two sources of compensation for its services on behalf of the issuer. One is through a commission (spread), the other is by buying issued shares for itself (or its affiliates) and reselling them in the post-issue market. Profits from the former decrease along with the magnitude of underpricing while profits from the latter increase with it. Faced with these countervailing interests, the present paper analyzes how the underwriter decides upon the pricing and allocation of IPOs.

投资者参与、企业内在价值与IPO抑价——基于中国A股市场的经验证据

本文以中国A股市场为背景,以2009～2010年沪深两市通过IPO募集股权资本的上市公司为样本,探讨了投资者参与程度、企业内在价值与IPO抑价之间的关系。研究发现,在诸多影响因素中,以市盈率衡量的企业内在价值与IPO抑价负相关;以中签率和换手率衡量的投资者参与程度,与IPO抑价正相关。较低的中签率和较高的换手率,代表更高的投资者参与热情,通常会导致更高的IPO抑价。此外,诸如IPO规模和行业特征等其他因素也会对IPO抑价产生影响。
