Liquidity and initial public offering underpricing

Using eight measures of liquidity, and addressing the potential endogeneity of initial returns, we find underpricing generally increases the secondary market liquidity of IPOs over the first year of trading, irrespective of the horizon over which liquidity is measured. For two model specifications over the eight measures, fifteen regressions display signs consistent with higher underpricing increasing liquidity and thirteen of these are statistically significant. We also find higher initial returns are significantly negatively correlated with the probability of informed trade. Furthermore, the liquidity effects of underpricing survive the lockup date, suggesting they are not quickly dissipated.     

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.     

Dual Class IPOs ARE Underpriced Less Severely

We analyze a sample of dual and single class initial public offerings (IPOs) to investigate whether empirical estimates of underpricing determinants are consistent across alternative measures of firm size and alternative techniques intended to account for underwriter price stabilization efforts. We find that results from long‐standing methods for estimating underpricing relations are generally robust to one's choice of size proxy and are consistent with estimates obtained from censored regressions of first‐day returns and from least squares regressions of longer horizon initial returns. We also confirm an existing finding in the literature that dual class IPOs endure less underpricing than do single class firms.     

Investor interest, trading volume, and the choice of IPO mechanism in France

This paper investigates the relationship between underpricing and investor interest level prior to and after the IPO date. Empirical tests show a significant 3-day buy-and-hold abnormal return of 19.15%. It is positively related to the share demand-to-offer ratio in the pre-market period and to trading volume in the aftermarket. Despite a high initial underpricing for some book-built issues, the book-building procedure allows for more effective pricing and a lower divergence of opinion among investors in the aftermarket than the auction-like procedure.     

THE EFFECT OF THE TRADING SYSTEM ON IPO UNDERPRICING: EVIDENCE FROM THE 1997 ORDER‐HANDLING RULES

We use a natural experiment resulting from the 1997 Securities and Exchange Commission rule mandating a change in the order‐handling rules (OHR) for all NASDAQ stocks to test whether secondary market structure affects initial public offering (IPO) underpricing. We find that the increase in liquidity that the OHR represent led to a decrease in underpricing for cold NASDAQ IPOs, suggesting that when liquidity is lowest, changes in market liquidity display a negative relation to initial returns.     

Laddering in initial public offerings

Laddering is a practice whereby the allocating underwriter requires the ladderer to buy additional shares of the issuer in the aftermarket as a condition for receiving shares at the offer price. This paper identifies factors that create incentives to engage in this type of manipulation and models the effect of laddering on initial public offering (IPO) pricing. I show that laddering has a bigger effect on the market price of IPOs with greater expected underpricing (without laddering) and greater expected momentum in the aftermarket; laddering increases the IPO offer price, the aftermarket price, and the money left on the table but does not necessarily increase the percentage underpricing; laddering contributes to long-run underperformance and creates a negative correlation between short-run and long-run returns; and profit-sharing increases the extent of laddering and the percentage underpricing.     

An empirical analysis of Mexican and US closed-end mutual fund IPOs

We examine 135 Mexican closed-end fund IPOs and 370 Mexican non-fund IPOs that issued between 1994 and 2003 along with 217 contemporaneous US fund IPOs and document three primary results. First, we find that Mexican IPOs in the aggregate experience no significant underpricing, unlike their US IPO counterparts. Both Mexican and US IPOs experience significantly negative long-run performance. Second, Mexican closed-end fund IPOs experience positive long-run performance, significantly better than Mexican non-fund IPOs which experience negative long-run performance. Unlike Mexican fund IPOs, US fund IPOs experience negative long-run performance. Third, we find that both Mexican and US debt-backed closed-end fund IPOs significantly outperform equity-backed closed-end IPOs. In Mexico, debt-backed funds experience positive abnormal returns, compared to negative abnormal returns for Mexican equity-backed funds, US debt-backed funds, and US equity-backed funds.     

Australian IPO pricing in the short and long run

We analyse both initial underpricing and post-listing returns for Australian IPOs. Our results are consistent with the view that unique institutional characteristics may have overwhelmed previous Australian tests of equilibrium models of IPO underpricing. The results also show that Australian IPOs significantly underperform market movements in the three-year period subsequent to listing. Further investigation of these anomalous post-listing returns lead us to reject various ‘speculative bubble’ explanations. Rather, the evidence suggests a curvilinear relationship between initial and subsequent returns, although the economic significance of the relationship is low.     

The underpricing of gold mining initial public offerings

This study is motivated by How [How, J., 2000. The initial and long run performances of mining IPOs in Australia. Aust. J. Manage. 25, 95-118] who examined 100 Australian gold mining initial public offerings (IPOs) from 1979 to 1990 to report an average 119.51% underpricing return by those IPOs. This study updates that analysis by investigating 114 Australian gold mining IPOs from 1994 to 2004 and finds a significantly lower 13.3% average first day return. Options offered to underwriters can in part explain these returns as can the change in either the Gold Index or the All Ordinaries Index from the date of the prospectus to the date of listing.     

The Underpricing and Excess Returns of Initial Public Offerings in Taiwan Based on Noisy Trading: A Stochastic Frontier Model

Initial public offerings (IPOs) are typically offered at prices lower than the transaction price in the early aftermarket. With a stochastic frontier model, we measured the fair offer price of an IPO and then the deliberate IPO underpricing and the market misvaluation based on the estimated fair offer price. Our results show that IPOs are deliberately underpriced. The extent of noisy trading leading to significantly higher market transaction prices explains the excess IPO returns. We conclude that initial IPO returns result primarily from the noisy trading activities instead of the deliberate IPO underpricing.     

Short selling in initial public offerings

Short sale constraints in the aftermarket of initial public offerings (IPOs) are often used to explain short-term underpricing that is subsequently reversed. This paper shows that short selling is integral to aftermarket trading and is higher in IPOs with greater underpricing. Perceived restrictions on borrowing shares are not systematically circumvented by “naked” short selling. Short sellers, on average, do not appear to earn abnormal profits in the near term and our findings are not driven by market makers. Short selling in IPOs is not as constrained as suggested by the literature, implying that other factors may be responsible for underpricing.     

THE PRICING OF EQUITY CARVE‐OUTS DURING THE 1990s

We examine the level of underpricing and characteristics of equity carveouts (ECOs) from 1990 to 1998 (the 1990s) and from 1999 to 2000 (the bubble period). For a sample of 458 ECOs, we find a mean initial return of 8.75% for the 1990s and 47.76% for the bubble period. The results suggest that, similar to other initial public offerings (IPOs), ECOs have been more willing to accept underpricing through time because of an increased importance in analyst coverage and the increased use of spinning, the practice where investment bankers allocate IPOs to high‐profile customers to garner potential future business.     

西方IPO抑价理论及对中国IPO研究的启示

西方IPO抑价理论大多在信息不对称、委托代理、信号显示等信息经济学框架下,基于资本市场的有效性假设而提出的,即假定二级市场对股票的定价是合理的,IPO抑价是源于发行定价偏低.中国A股市场IPO抑价率长期高企但逐年下降,对该问题的研究,不能简单套用西方理论,而必须结合我国证券市场环境及IPO发行审核制度,将制度因素作为内生变量来考察.     

Underpricing, Subsequent Equity Offerings, and the Long-Run Performance of Japanese IPOs

Using data on IPOs that are issued in Japan during January 1975–March 1989, we examine the deliberate underpricing and overreaction hypotheses to explain high initial returns at offering dates. Specifically, we analyze the cross-sectional pattern of the short- and long-run performance of IPOs. The obtained results indicate that the deliberate underpricing theories which we examine are unable to explain the high initial returns on the Japanese IPOs. Furthermore, for the average of the IPOs, the empirical results are not consistent with the overreaction hypothesis. However, there is evidence consistent with the hypothesis that for a certain minority group of IPOs, the high initial returns occur due to overreactions by investors. We interpret the overall results as indicating that the high initial returns on the Japanese IPOs can be attributed to a mixture of both underpricing and investor overreaction. We conjecture that the binding regulations in Japan led to underpricing. This revised version was published online in August 2006 with corrections to the Cover Date.     

IPO initial returns in China: Underpricing or overvaluation?

This paper separates the amount of IPO underpricing(primary market underpricing) and overvaluation(secondary market overvaluation) from the value of an IPO's initial return to evaluate the relative importance of these two factors and their main determinants. Using data on the IPOs of 948 Chinese firms, we find that average initial returns are 66% and that underpricing and overvaluation are between 14–22% and 44–53%, respectively, depending on the method used to assess firms' intrinsic values. In addition, while both the value of the initial return and the extent of overvaluation are significantly negatively related to post-IPO long-run stock performance, overvaluation can predict post-IPO performance better than the value of the initial return. Value uncertainty in IPOs is positively related to both underpricing and overvaluation, and both the underwriter's reputation and the existence of pricing regulation are positively related to underpricing. Investor sentiment has a positive effect on overvaluation but has no effect or a negative effect on underpricing. Overall, our results suggest that in China overvaluation accounts for a larger proportion of the initial return than underpricing,and that underpricing and overvaluation have different determinants.     

Initial and Long-Run IPO Returns in Central and Eastern Europe

ABSTRACT

This article provides original evidence on IPO underpricing and long-run underperformance in Central and Eastern Europe (CEE) and compares results to the European Union’s developed capital markets from 2000 to 2009. Using both index-adjusted and CAPM-adjusted returns, we find significant underpricing that is significantly higher than underpricing of comparable IPOs in the European Union’s developed capital markets. We show that the CEE’s initial IPO returns also exhibit significantly higher volatility. In line with the asymmetric information theory, we indicate that smaller IPOs in the CEE region have greater underpricing than the larger IPOs. Contrary to the literature, we unambiguously confirm long-run underperformance toward the benchmarks. In some model specifications, we also find that IPO long-run underperformance in the CEE region is less present than in the European Union’s developed capital markets.     

Firm characteristics and long-run stock returns after corporate events

The well-documented abnormal long-run buy-and-hold returns to firms issuing equity in initial public offerings and seasoned equity offerings, firms bidding in mergers, and firms initiating dividends can be attributed to imperfect control-firm matching. In addition to firm size and market-to-book ratio, event firms on average differ from control firms in terms of idiosyncratic volatility, liquidity, return momentum, and capital investment, each of which also explains returns. We propose a simple regression-based approach to control for differences in firm characteristics across event and control firms, and we show that long-run abnormal returns do not differ significantly from zero for event firms in the 1980 to 2005 period. The returns to event firms are, therefore, consistent with patterns known to exist for the broad stock market and do not require event-specific explanations.     

Underpricing of IPOs: Firm-, issue- and country-specific characteristics

Using a large firm-level dataset of 2920 IPOs from 21 countries we examine the impact of country-level institutional characteristics on the underpricing of IPOs. Through hierarchical linear modeling we are able to control for firm-specific and issue-specific characteristics and test whether country-specific institutional characteristics add explanatory power to explain the level of underpricing. Our results show that about 10% of the variation in the level of underpricing is between countries. The quality of a country’s legal framework, as measured by its level of investor protection, the overall quality of its legal system and its level of legal enforcement, reduces the level of underpricing significantly.     

Signalling and the Long‐run Performance of Spanish Initial Public Offerings (IPOs)

Abstract:   Academic research into firms that have gone public has focused on the study of two anomalies: initial underpricing and long‐run underperformance. We analyse Spanish Initial Public Offerings to provide additional evidence on the long‐run performance of IPOs and its relationship with initial underpricing. Results reveal the existence of negative long‐run abnormal stock returns, in line with the international literature. Long‐run performance presents a positive relationship with underpricing and the volume of funds obtained in seasoned offerings, in consonance with the predictions of Allen and Faulhaber (1989) , Welch (1989) and Grinblatt and Hwang (1989) .
