香港市场基石投资者制度的实践与借鉴

基石投资者是香港IP O市场引导合理定价、提高发行效率的一项重要制度安排。本文对2013―2019年港股I P O进行实证分析,发现引入基石投资者可以提高IPO定价效率,帮助体量较大或估值较难的企业顺利上市,在低迷行情中起到市场稳定器的作用,但同时也存在个股流动性不足、利益输送等风险隐患。考虑到国内外形势复杂严峻,市场不确定性增强,注册制改革加速推进,新股稀缺性优势减弱,有必要借鉴香港基石投资者制度经验,进一步优化A股现行战略配售制度,合理稳定市场预期。同时,建议加强对参与战略配售投资者的信息获得、持股限售期以及信息披露等方面的监管力度。     

‘Slow-burn’ spillover and ‘fast and furious’ contagion: a study of international stock markets

‘Fast and furious’ contagion across capital markets is an important phenomenon in an increasingly integrated financial world. Different from ‘slow-burn’ spillover or interdependence among these markets, ‘fast and furious’ contagion can occur instantly. To investigate this kind of contagion from the US, Japan and Hong Kong to other Asian economies, we design a research strategy to capture fundamental interdependence, or ‘slow-burn’ spillover, among these stock markets as well as short-term departures from this interdependence. Based on these departures, we propose a new contagion measure which reveals how one market responds over time to a shock in another market. We also propose international portfolio analysis for contagion via variance decomposition from the portfolio manager’s perspective. Using this research strategy, we find that the US stock market was cointegrated with the Asian stock markets during four specific periods from 3 July 1997 to 30 April 2014. Beyond this fundamental interdependence, the shocks from both Japan and Hong Kong have significant ‘fast and furious’ contagion effects on other Asian stock markets during the US subprime crisis, but the shocks from the US have no such effects.     

Disclosure of Intended Use of Proceeds and Underpricing in Initial Public Offerings

We use the context of a company's initial public offering (IPO) of equity securities as a capital‐markets setting to empirically study the economic consequences of endogenous disclosure. In particular, we examine the relation between the extent of dollar detail an IPO issuer provides regarding their intended use of proceeds and first‐day underpricing. We document substantial variation in the specificity of this disclosure and find that an increase in such specificity is associated with lower IPO underpricing. Overall, our results suggest that IPOs that provide specific use‐of‐proceeds disclosures have less ex ante uncertainty, in the sense that these disclosures help investors estimate the dispersion of secondary market values. Our paper contributes to the empirical accounting literature by documenting an association between voluntary disclosure and what is arguably the foremost cost of raising initial equity capital (i.e., IPO underpricing).     

Issuer-oriented underpricing costs in initial public offers: Evidence from Hong Kong

This paper estimates the underpricing cost associated with new shares issued and sold when firms go public in a traditional British-style IPO market in contrast to prior work which focussed on the underpricing cost to pre-IPO investors. Secondly, the estimates account for interest income on application funds received by issuing firms. Using data from the Hong Kong IPO market, the results show that the issuer underpricing cost of new share issues is on average only 14% of headline underpricing. When interest on application funds is taken into account, net issuer underpricing cost reduces to just around 7% of headline underpricing. This finding provides a compelling explanation of why issuing companies may not be concerned about underpricing in traditional British-style IPO markets. Thirdly, we also find that pre-IPO investors take steps to minimise wealth transfer to new investors either by selling a very small proportion or none of their pre-IPO shares. These findings suggest that explanations of IPO underpricing to the various parties involved in the process should, in part, be sought in the institutional structures and investment banking practices of the relevant primary capital market.     

The effect of market segmentation on stock prices: The China syndrome

China has an A-share market that is open only to local investors and a B-share market that is open only to foreign investors. Contrary to what has been observed in other markets with a similar segmented structure, the China B shares trade at a discount relative to the A shares. We show that the phenomenon can still be explained by basic economic principles. Specifically, the existence of the H-share and the “red-chip” markets in Hong Kong provide good substitutes for the B-share market. We find that when more H shares and red chips are listed in Hong Kong, the B-share discount becomes larger. This is consistent with the model of differential demand elasticity proposed by Stulz and Wasserfallen (Stulz, R., Wasserfallen, W., 1995. Review of Financial Studies 8, 1019–1057).     

Underpricing of homecoming A-share IPOs by Chinese firms already listed abroad

Many Chinese firms have pursued overseas listings in Hong Kong or US without being first listed in China’s domestic market, mainly due to the regulatory constraints imposed by the Chinese government. Some of them eventually returned to mainland China through an A-share offering to Chinese investors. This unique feature of cross-listed Chinese stocks offers an experiment field to test some of the conventional theories of initial public offerings (IPOs) underpricing. Homebound IPOs are expected to be less underpriced than domestic only IPOs that are not cross-listed because being already listed in a developed market can mitigate the information asymmetry and issue uncertainty associated with their A-share IPOs. Nevertheless, we find that homecoming A-share IPOs are still substantially underpriced, with an average market adjusted first-day return of 96.53 %. Furthermore, their first-day returns are not significantly different from those of domestic only IPOs once firm- and offer-characteristics are controlled. This is in sharp contrast to the lukewarm aftermarket performance experienced in their overseas debuts. The mean market adjusted first-day return is merely 5.35 % in their US ADR offerings and 11.63 % in their Hong Kong H-share IPOs. Overall, our results suggest the importance of local market structures and norms as influential factors of IPO underpricing.     

Market Segmentation and Information Asymmetry in Chinese Stock Markets: A VAR Analysis

This study examines the market segmentation and information asymmetry patterns in Chinese stock markets. The recursive cointegration analysis confirms that each of six markets is not linked with other markets in the long run. Further, the result from data‐determined forecast error variance decomposition clearly shows that foreign investors in the Shanghai B‐share market are better informed than Chinese domestic investors in two A‐share markets and foreign investors in Shenzhen and Hong Kong markets over time. The finding challenges a widespread assumption of less informed foreign investors in the literature, but suggests that foreign investors could be more informed in emerging markets.     

资本市场开放与股权资本成本——基于沪港通、深港通的实证研究

本文基于沪港通和深港通研究资本市场开放对中国内地股权资本成本的影响。研究发现,受政策风险和市场环境等因素所限,沪港通在初始阶段并未对沪市公司的股权资本成本产生显著影响,但随着政策进一步完善、市场逐渐稳定和交易不断活跃,其对股权资本成本的降低效果于实施两年后开始显现;深港通建立在沪港通的制度基础和运行经验上,其在开通后显著降低了标的公司的股权资本成本。本文还进一步分析了资本市场开放影响股权资本成本的竞争渠道和信息渠道,发现深港通对股权资本成本的降低作用主要集中在投资者竞争程度较高,或是公开信息质量较高、信息不对称程度较低的股票样本。     

STOCK MARKET OPENNESS AND MARKET QUALITY: EVIDENCE FROM THE SHANGHAI–HONG KONG STOCK CONNECT PROGRAM

We study the impact of capital market openness on high-frequency market quality in China. The Shanghai–Hong Kong Stock Connect program (SHHKConnect) opens China's stock market to foreign investors and offers a natural experiment to investigate this question. Using a difference-in-differences approach, we find that market liberalization leads to lower quoted spread, lower effective spread, lower market depth, and higher short-term volatility. Our findings imply that opening the markets to more sophisticated foreign investors is associated with higher competition and more cross-market arbitrage activities, narrowing the spread and reducing liquidity providers’ profits, but increasing the price impact and short-term volatility of connected stocks.     

Underwriters' allocation with and without discretionary power: Evidence from the Hong Kong IPO market

This study uses a unique and extensive data set from the Hong Kong IPO market to examine the theory of adverse selection under two distinct regulatory regimes in relation to underwriters' discretionary power in IPO share allocation. Consistent with Rock's (1986) theory of adverse selection in the IPO market, we show that, prior to the introduction of the clawback provision; retail (uninformed) investors were allocated more of the overpriced offerings and less of the underpriced issues. However, after the provision is implemented, retail investors have been allocated significantly more of the underpriced offerings and less of the overpriced ones. Overall, we find that allocation-adjusted initial returns for the retail investors are lower (higher) than the risk-free rate pre- (post-) clawback provision. These findings imply that the mandatory clawback provision has enhanced the fairness in IPO share allocations among different investor groups and has reduced the winner's curse in the IPO market.

Modelling long run comovements in equity markets: A flexible approach

International equity markets linkages are characterized by nonlinear dependence and asymmetries. We investigate shifts in long run comovements in stock markets by means of an ‘interrupted’ Markov switching cointegration specification. This flexible approach allow us to study to what extent documented changes in global integration are permanent, or whether market linkages are subject to changes. Using an illustrative sample from 1980 to 2012 for USA, UK and Hong Kong stock price indices, we find evidence of interrupted cointegration across these markets between May 1997 and April 2002, which is consistent with the decoupling of stock prices from fundamentals during the dot-com bubble.     

Determinants and consequences of voluntary switches to Chinese auditors in Hong Kong

Hong Kong market regulators have permitted 12 large Chinese accounting firms to audit the financial statements of Chinese firms that cross list in Hong Kong (i.e., H-share firms) since 2010. This paper examines the characteristics of H-share firms that voluntarily replaced their Hong Kong (HK) auditors with Chinese auditors, and the market reaction to auditor switches following this policy. We find that 38 out of 147 H-share firms voluntarily switched to Chinese auditors during 2011–2013. Switching firms are larger in size and are less likely to use Big4; they also have less need for external financing, a longer cross listing history, and a lower percentage of foreign revenue. We also find that investors negatively react to the auditor switches from HK non-Big4 to China non-Big4, but do not react to the auditor switches from HK Big4 to China Big4. This suggests that investors perceived lower audit quality for China non-Big4.

IPO activity and information in secondary market prices

This paper explores the link between IPO underpricing and financial markets. In my model the IPO is a mean for a capital constrained initial investor to exit and thereby to raise funds for a new investment opportunity. This investor is privately informed vis-a-vis outside investors about the profitability of the new opportunity and the quality of the firm to be offered in the IPO. He can then use the offer price and the fraction of shares sold as signals of his private information. The model shows that underpricing is not only linked to firm’s characteristics, i.e. firm value, but to elements external to the firm, i.e. new investment profitability and financial markets characteristics. In particular higher market efficiency reduces the cost of listing. This results in lower underpricing and the listing of more valuable firm. Similarly, a higher lower bound of the new investment’s profitability reduces the information asymmetry and hence reduces underpricing and widens the range of firms listed.

Determinants of returns and volatility of Chinese ADRs at NYSE

This paper examines the determinants of returns and of volatility of the Chinese ADRs as listed at NYSE. Using an autoregressive conditional heteroskedasticity (ARCH) model and data from 16 April 1998 through 30 September 2004, we find that Hong Kong stock market (underlying market), US stock market (host market), and local (Shanghai A and B) markets all are important determinants of returns of the Chinese ADRs. However, the underlying Hong Kong market has the most significant impact on mean returns of the ADRs. In terms of the determinants of the conditional volatility of the ADRs returns, only shocks to the underlying markets are significant. These results are consistent with [Kim, M., Szakmary, A.C., Mathur, I., 2000. Price transmission dynamics between ADRs and their underlying foreign securities. Journal of Banking and Finance 24, 1359–1382] who find that the most influential factor in pricing the ADRs in Japan, UK, Sweden, The Netherlands and Australia is their underlying shares. Implications of the results for investors are discussed.     

IPO underpricing,signaling, and property returns

This paper investigates whether IPO signals reveal proprietary information about the prospects of an issuing firm’s underlying industry. By analyzing a sample of European property company (EPC) IPOs from 1997 to 2007, we take advantage of a heterogeneous set of industry performance measures, i.e., yields and total returns of direct property investments in various European property markets that can be clearly assigned to each individual IPO. The results reveal that the main signal of interest, underpricing, is in fact positively related to average property yields for a 12-month post-IPO period; a result that supports our assumption. Other signals, as proposed in previous research, do not appear to contain any information about the prospects of the IPO firm’s target property investment market. We also show that total returns seem to be a biased measure for direct property performance. Further tests for the signaling model’s preconditioned presence of information asymmetry among EPCs reveal that underpricing levels are a function of company-specific ex ante uncertainty proxies. In contrast, property-specific ex ante uncertainty proxies do not explain underpricing levels.     

Voluntary profit forecast disclosures,IPO pricing revisions and after-market earnings drift

Prospectus profit forecasts (PPF) constitute one of the most important discretionary disclosure items in an IPO. I examine such disclosures in the Hong Kong market, where both IPO activity and PPF disclosure rates are at high levels. The median forecast typically ‘underestimates’ future earnings by around 6%. More importantly, PPF disclosure exhibits a strong inverse association with pre-listing owners' retained equity levels (Hughes, 1986; and Li and McConomy, 2004). PPF disclosure is thus more likely in IPOs raising more capital and generating larger floats. I also demonstrate a strong link between PPF disclosure and post-IPO earnings drift.Ensuing forecast errors also bear strong connection with IPO coordinators' initial price determinations as well as with subsequent investor returns. This area usefully extends the related literature (Cheng and Firth, 2000; Chen, Firth and Krishnan, 2001; Jog and McConomy, 2003; Chong and Ho, 2007; and Gounopoulos, 2011), which stresses an association between forecast errors and initial investor returns but ignores the preceding price ‘determination’ process. It also suggests that forecast errors serve as a valuable ex-post proxy for the amount of ex-ante uncertainty surrounding issuer value (Beatty and Ritter, 1986; Falconieri, Murphy and Weaver, 2009). This study also demonstrates a connection between final offer price ‘determinations’ and the information content and “superiority” of PPFs (Brown, Richardson and Schwager, 1987). Finally, and in contrast to final offer price ‘determinations’, initial investor returns strongly anticipate post-IPO earnings drift.     

Did China avoid the ‘Asian flu’? The contagion effect test with dynamic correlation coefficients

Many economists believe that China avoided the so-called Asian flu due to its strong balance of payments position and substantial foreign reserves. This study introduces an improved method for testing financial-crisis contagion and shows that crisis-contagion effects were significant among Thailand and the Chinese economic area (i.e. China, Hong Kong, and Taiwan) stock markets during the Asian financial crisis. The main contribution of this study is its use of a two-step procedure to identify the crisis dates for testing for contagion and data pertaining to a growing triangular economic area during the Asian financial crisis. This result suggests that if investors ignore the economic and financial information within regional markets, they will face an increase in uncertainty vis-à-vis investment returns.
