合资承销商影响新股破发率的实证研究

新股破发是目前中国股市目前面临的一个重要现象。本文基于2004年至2010年上市的A股IPO,研究合资承销商对新股破发率的影响。研究发现,合资承销商所承销的新股破发率显著低于本土承销商。合资承销商的低破发率主要归功于更加有效且符合市场预期的一级市场发行定价能力,其表现为合资承销商发行的股票的短期市场价格相对发行价的偏离程度显著低于本土承销商发行的股票。另外,我们还发现合资承销商采取了一定的托市行为,该行为也减小了短期内新股跌破发行价的概率。本文的发现从新股发行的角度提供了开放金融市场对我国资本市场影响的新现象。     

Perceptions and Price: Evidence from CEO Presentations at IPO Roadshows

This paper examines the relation between cognitive perceptions of management and firm valuation. We develop a composite measure of investor perception using 30‐second content‐filtered video clips of initial public offering (IPO) roadshow presentations. We show that this measure, designed to capture viewers’ overall perceptions of a CEO, is positively associated with pricing at all stages of the IPO (proposed price, offer price, and end of first day of trading). The result is robust to controls for traditional determinants of firm value. We also show that firms with highly perceived management are more likely to be matched to high‐quality underwriters. In further exploratory analyses, we find the impact is greater for firms with more uncertain language in their written S‐1. Taken together, our results provide evidence that investors’ instinctive perceptions of management are incorporated into their assessments of firm value.     

The Economics of IPO Stabilisation,Syndicates and Naked Shorts

Stabilisation is the bidding for and purchase of securities by an underwriter immediately after an offering for the purpose of preventing or retarding a fall in price. Stabilisation is price manipulation, but regulators allow it within strict limits – notably that stabilisation may not occur above the offer price. For legislators and market authorities, a false market is a price worth paying for an orderly market. This paper compares the rationale for regulators' allowing IPO stabilisation with its effects. It finds that stabilisation does have the intended effects, but that underwriters also seem to have other motives to stabilise, including favouring certain aftermarket sellers and enhancing their own reputation and profits. A puzzling aspect of stabilisation is why underwriters create ‘naked short’ positions which are loss‐making to cover when, as is usual, the aftermarket price rises to a premium. We set up a model to show that the lead underwriter may profit from a naked short at the expense of the rest of the syndicate given the way commissions are apportioned between them. We argue that a naked short mitigates the misalignment of interests which stabilisation causes between issuer and lead underwriter, although it does so at the expense of the non‐lead underwriters.     

Does the Market Incorporate Previous IPO Withdrawals When Pricing Second‐Time IPOs?

This paper examines the initial public offering (IPO) valuations of issuers that return to the IPO market successfully after withdrawing their first IPO attempt. We find that these second-time IPOs sell at a significant discount relative to similar contemporaneous IPOs that succeed in their first attempt. We also demonstrate that switching underwriters on the second IPO attempt reduces, but does not eliminate, the discount for second-time IPOs. When compared to their matched first-time IPOs, second-time IPOs have similar price revisions and post-IPO long-run stock and operating performances. Overall, these results suggest that the negative information conveyed by the withdrawal event is incorporated into the lower offer valuations for second-time IPOs. Switching investment banks can mitigate, but not eliminate, the perceived higher risk of the second-time offerings.     

How Do Underwriters Select Peers When Valuing IPOs?

Valuing initial public offerings (IPOs) using multiples allows underwriters discretion when selecting comparable firms. We find that they systematically exclude candidate comparable firms that make a given IPO appear overvalued. On average, comparable firms published in official prospectuses have 13%‐38% higher valuation multiples than those obtained from matching algorithms or selected by sell‐side analysts, including the same underwriter's analyst after the IPO. Even if IPOs are priced at a discount as compared to peers selected by the underwriters, they are still at a premium with regard to alternatively selected peers. Greater bias in the underwriter's selection of peers leads to poorer long run performance.     

Issuer Operating Performance and IPO Price Formation

We study the relation between issuer operating performance and initial public offering (IPO) price formation from the initial price range to the offer price to the closing price on the first trading day. For a post‐bubble sample of 2001–2013 IPOs, we find that pre‐IPO net income and, in particular, operating cash flow are strongly, positively associated with the revision from the mid‐point of the initial price range to the offer price and that the “partial adjustment phenomenon” concentrates among issuers with the strongest operating performance. As for why publicly observable information helps predict changes in valuation from when the initial price range is set to when the offer price is set, our findings suggest that strong‐performing issuers, especially those offering small slices of ownership, have lower bargaining incentives and are susceptible to the underwriter(s) low‐balling the price range. Overall, our results suggest an important role for accounting information in understanding the pricing of book‐built IPOs and are consistent with the presence of agency problems between issuers and underwriters.        

Underwriter reputation and IPO underpricing: The role of institutional investors in the Chinese growth enterprise market

This paper investigates the effects of underwriter reputation on initial public offering (IPO) underpricing in the Chinese Growth Enterprise Market, in light of the conflicting evidence in the literature on IPO underpricing. Using data during the post global financial crisis period, we find that IPO firms with prestigious underwriters have lower market-adjusted initial returns on average. We further find that prestigious underwriters reduce IPO underpricing by minimizing the time gap between the offering and listing, choosing high-quality firms to underwrite, and reducing information asymmetry between issuers and investors. In the presence of institutional investors, however, we find that more underpricing occurs, as these investors tend to obtain access to IPO shares at a higher price discount via private placements. This new finding suggests that the institutional investors have a role to play in the case of high under-pricing, which partly gets corrected via underwriter reputation.     

IPOs with and without allocation discretion: Empirical evidence

Bookbuilding, the dominant offering mechanism for IPOs, is controversial because of the power it gives underwriters over IPO allocations. Critics argue that allocations could be abused to generate kickbacks for underwriters while proponents hold that allocation power could improve pre-market price discovery. We examine underpricing, bidding, and allocations from two regimes in the Indian IPO market with varying underwriter allocation power. When underwriters control allocations, bookbuilding is associated with lesser underpricing, but the effect quickly dissipates when regulations withdraw allocation powers. Using proprietary datasets of IPO books in both regimes, we find that allocation powers are used quite extensively. Identical bids can receive significantly different allocations, which depend not only on the bid but also on the bidder identity. When allocation powers are withdrawn, we find evidence of bidder exit, new bidder entry, and altered bidding strategies with exit by both favored and unfavored bidders. Our evidence supports bookbuilding theories in which giving underwriters allocation powers assists in pre-market price discovery.     

An analysis of the liquidity benefits provided by secondary markets

Listing shares in liquid secondary markets either to facilitate acquisitions or to diversify owner’s personal wealth are among the most important reasons for firms to go public [Brau, J.C., Fawcett, S.E., 2006. Initial public offerings: An analysis of theory and practice. Journal of Finance 61, 399–436]. We contend that the expected benefits derived from the liquidity provided by secondary markets are relevant for understanding important decisions made in preparation for an IPO. We hypothesize that the potential losses caused by an IPO failure induce firms that benefit more from going public to hire more reputable underwriters and to adopt more conservative pricing policies. We use several proxies for the benefits firms derive from post-IPO liquidity. The results indicate that firms that benefited more from liquidity were taken public by more prestigious underwriters and exhibited substantially larger levels of price revisions and underpricing. Post-IPO liquidity is also important for understanding the decision to retain the lead underwriter in subsequent SEOs.     

IPO Placement Risk and the Number of Co‐Managers

Previous studies show that co‐managers mainly affect initial public offering (IPO) aftermarket activities. We investigate the role of co‐managers in IPO pre‐market activities. We argue that co‐managers help reduce IPO placement risk and hypothesize that IPO issuers hire more co‐managers when placement risk is higher. We find the number of co‐managers is positively associated with three proxies for placement risk. IPOs with more price uncertainty and high‐tech IPOs hire more co‐managers, while IPOs in regulated industries hire fewer co‐managers. We also find larger IPOs, recent IPOs, and IPOs with more reputable lead underwriters hire more co‐managers.

The impact of the institutional environment on the value relevance of fair values

Most prior studies attribute valuation discounts on certain fair valued assets to measurement error or bias. We argue that institutional differences across countries (e.g., information environment or market sophistication) affect investors’ ability to process and impound fair value information in their valuation. We predict that the impact of the institutional environment on value relevance is particularly pronounced for reported fair values of assets designated at fair value through profit or loss (hereafter, “FVO assets”), for which investor experience is lowest and complexity is highest. Using a global sample of IFRS banks, we find that FVO assets are generally less value relevant than held-for-trading assets (HFT) and available-for-sale assets (AFS). By partitioning countries into market- and bank-based economies to proxy for institutional differences, we find that the valuation discount on FVO assets is more pronounced in bank-based economies. Additional tests suggest that this valuation discount is attenuated by a richer firm-level information environment and the presence of institutional investors with fair value experience.     

Heterogeneous Beliefs,IPO Valuation,and the Economic Role of the Underwriter in IPOs

We empirically analyze the economic role of the underwriter in initial public offerings (IPOs), distinguishing between the “certification” and “market power” hypotheses. We find that equity in high‐reputation underwriter backed IPOs is priced higher and further away from intrinsic value than that in low‐reputation underwriter backed IPOs. Our results are robust to controlling for the endogenous selection of firms to take public by underwriters. Overall, our results support the market power hypothesis and reject the certification hypothesis, indicating that the role of underwriters is to obtain the highest possible valuation for the IPOs that they back rather than to price the equity close to intrinsic value.     

IPO Trading without Market Makers or Underwriter Price Support

We investigate the trading behavior and liquidity supply of Chinese initial public offerings (IPOs) that trade in an order‐driven market system with pure limit order books where no market makers or price support is allowed. We find large trades and quoted depths dominate the first day of trading, but this pattern quickly reverses as small trades and quoted depths are more prevalent on subsequent trading days. Quoted depths are positively related to the number of shares offered in the IPO and trade size, but are negatively related to underpricing. Trade size and transaction immediacy are positively related, and large and positive (negative) order imbalance is associated with more aggressive buys (sells). Finally, long‐run performance is not related to initial order imbalance. Overall, our results suggest that despite underwriters not participating in the IPO aftermarket, liquidity provision evolves very quickly and price discovery is immediately reflected in prices.     

Uncertain Demand,Heterogeneous Expectations,and Unintentional IPO Underpricing

Distinguishing between intentional and unintentional incentives to underprice initial public offerings (IPOs), I develop sufficient conditions for the winners' curse postulated by Miller (1977) and implications for intertemporal changes in the magnitude of underpricing. Specifically, I show that unintentional underpricing (and occasional overpricing) of IPOs is a consequence of investors' heterogeneous expectations of the uncertain value of a stock when the supply is constrained and the underwriter's price discovery process only partially identifies aggregate demand. Moreover, an IPO that is oversubscribed in the premarket sale almost certainly will experience a short‐term price increase in the secondary market.     

Deliberate premarket underpricing and aftermarket mispricing: New insights on IPO pricing

We decompose initial returns into deliberate premarket underpricing and aftermarket mispricing using stochastic frontier analysis. We model deliberate underpricing as a function of proxies of information asymmetry surrounding IPO value between market participants. Equity retained is an unlikely signalling mechanism to convey IPO value to outside investors through deliberate premarket underpricing. The presence of lock-in agreements, underwriter fees, number of uses of proceeds, and venture capital or private equity backing have positive impacts on deliberate premarket underpricing. Demand for firms' capital also explains deliberate premarket underpricing, whereas new issues market conditions have no impact. All these factors are found to explain a significant fraction of the variations in our deliberate underpricing estimates. Deliberate underpricing is the more dominant component that makes up initial return when compared to the fraction of aftermarket mispricing. We attribute aftermarket mispricing to trading volume in IPO shares on the first day, price adjustment between the filing price range and the offer price, and offer size. Equity retained explains the aftermarket mispricing rather than the deliberate premarket underpricing in contradiction to the signalling argument. More reputable underwriters are likely to provide price support in the early aftermarket, whereas we observe no impact on deliberate premarket underpricing.     

Securities regulation and implicit penalties

The extant literature offers extensive support for the significant role played by institutions in financial markets, but implicit regulation and monitoring have yet to be examined. This study fills this void in the literature by employing unique Chinese datasets to explore the implicit regulation and penalties imposed by the Chinese government in regulating the initial public offering (IPO) market. Of particular interest are the economic consequences of underwriting IPO deals for client firms that violate regulatory rules in China’s capital market. We provide evidence to show that the associated underwriters’ reputations are impaired and their market share declines. We further explore whether such negative consequences result from a market disciplinary mechanism or a penalty imposed by the government. To analyze the possibility of a market disciplinary mechanism at work, we investigate (1) the market reaction to other client firms whose IPO deals were underwritten by underwriters associated with a violation at the time the violation was publicly disclosed and (2) the under-pricing of IPO deals undertaken by these underwriters after such disclosure. To analyze whether the government imposes an implicit penalty, we examine the application processing time for future IPO deals underwritten by the associated underwriters and find it to be significantly longer than for IPO deals underwritten by other underwriters. Overall, there is little evidence to suggest that the market penalizes underwriters for the rule-violating behavior of their client firms in China. Instead, the Chinese government implicitly penalizes them by imposing more stringent criteria on and lengthening the processing time of the IPO deals they subsequently underwrite.     

Overreaction in the thrift IPO aftermarket

We study the initial returns and long-run performance of a unique sample of thrifts that have recently converted from mutual to stock form. In addition to a full claim on all IPO proceeds, new investors in a converted thrift also receive a claim on all pre-conversion market value at no cost. Thus, the average firm in our sample has a degree of underpricing automatically built into its offer price. We find that after removing the large initial returns, cumulative excess returns for the firms in our sample are positive for 12 months after the IPO. Beginning in the second year after the IPO, the average firm in our sample undergoes a significant price correction that lasts approximately 18 months and which produces negative cumulative abnormal returns for up to 5 years post-issue. Differences in risk-adjusted returns also indicate negative long-run returns, with poor performance concentrated in the second and third years following the IPO. The return differences are most pronounced among the small thrifts in our sample, and are broadly consistent with investor overreaction at the time of the IPO that continues for 6–12 months before prices begin reverting back to fundamental value.     

Underwriter learning about unfamiliar firms: Evidence from the history of biotech IPOS

This study examines the ability of underwriters to properly value unfamiliar firms prior to issuance. I use a sample of IPOs in biotechnology, a relatively new but thriving industry. The first American biotech IPO was in 1980. Through the end of 2004, almost 500 biotech IPOs have appeared in the public market. I find that biotechnology differs from other industries in the attributes of individual firms valued by the market. In particular, R&D and the quality of human capital (e.g., star scientists on the staff) are much more important for biotech valuations. I find also that underwriters appeared not to appreciate this distinction for early biotech IPOs; in those cases, first-day market returns were predictable by firm attributes not used by underwriters to establish IPO issue prices. I also find that underwriters have learned over time, albeit slowly. Over the 20+ years of biotech history, IPO issue prices have become more dependent on firm attributes unique to biotechs while first-day market returns have become less predictable.     

Do the equity holding and soundness of bank underwriters affect issue costs of SEOs?

This paper examines the effects of characteristics of bank underwriters on issue costs in seasoned equity offerings in Japan following deregulation in 1999. I find that banks’ holding loans have a negative effect on price discounts and no effect on underwriting fees. However, banks’ equity holdings have no effect on discount rates and a positive effect on underwriting fees. Furthermore, issuers with unhealthy banks pay higher discount rates, are more likely to be weak in their ex-post operating performance, and are less willing to switch underwriters. I conclude that the characteristics of banks have different effects on issue costs.
