Explaining underpricing of IPOs in frontier markets: Evidence from the Nigeria Stock Exchange

The paper provides empirical analyses of IPO underpricing on the Nigerian Stock Exchange, from the period 1990 to 2006. The results indicate an average abnormal initial day returns of 43.1%. There is evidence of long-run underperformance of 0.6%. Results from our regression model explaining initial abnormal returns for the IPOs of Nigeria show that size of firm and audit quality are important variables affecting underpricing. The results also show the presence of a non-linear relationship between the offer price and underpricing.     

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.     

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 Thrift IPO as the First Stage of its Subsequent Sale

Although the underpricing of initial public offerings (IPOs) has been well documented, the underpricing of foreign IPOs have received relatively little attention. In a comparative analysis of foreign and domestic IPOs in the U.S. market for the 1990-1993 period, we find that for a matched sample, foreign IPOs are significantly more underpriced. Our results are consistent with the models developed by Rock (1986), Beatty and Ritter (1986), and Carter and Manaster (1990). Examination of the characteristics of foreign IPOs reveals that they are more likely to be larger in size, employ more prestigious underwriters and are much more likely to list on the New York Stock Exchange (NYSE).     

UNDERPRICING OF IPOS THAT FOLLOW PRIVATE PLACEMENT

In this study we examine the underpricing of initial public offerings (IPOs) by firms that have private placements of equity before their IPOs (PP IPO firms). We find that PP IPOs are associated with significantly less underpricing than their peers. Furthermore, PP IPOs are associated with lower underwriting spreads, more reputable underwriting syndicates, and greater postissue analyst coverage as compared to IPOs that are issued by their industry peers under similar market conditions. Consistent with the implications of the information asymmetry explanation for IPO underpricing, our findings suggest that companies could benefit by conveying their quality via successful pre‐IPO private placements that help reduce the cost of going public.     

A Comparison of Underwriting Costs of Initial Public Offerings by Investment and Commercial Banks

We examine differences in underwriting costs between commercial‐bank‐Section‐20‐underwritten initial public offerings (IPOs) and investment‐bank‐underwritten IPOs. Our results suggest that total underwriting costs (gross margin plus underpricing) are significantly lower for commercial bank IPOs. The lower cost for commercial bank IPOs is attributable to less severe underpricing for these issues. Gross margin costs generally do not differ between commercial bank and investment bank issues. Furthermore, we find that the long‐run stock price performance for commercial bank issues is superior to that of investment bank issues. That is, lower underpricing for Section 20 issues may not be a short‐run phenomenon. Rather, there appears to be a favorable outcome for investors in the long run for holding IPOs underwritten by Section 20 commercial banks. These results are inconsistent with the conflict of interest hypothesis often associated with merging commercial and investment bank functions in one organization.     

Model specification and IPO performance: New insights from Asia

This study examines the post-issue stock price performance of initial public offerings (IPOs) from advanced and emerging Asian markets from 1991 to 2004. We provide a comparative assessment on the short- and long-term stock performance of Asian IPOs with comprehensive international evidence. We use several different methods to examine the robustness of IPO performance. Our results reveal that whilst there is initial underpricing in Asian IPOs, the existence of long-run underperformance for the Asian IPOs depends resoundingly on the methodology used for assessment.     

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.     

REGULATORY AND PROCEDURAL EFFECTS ON THE UNDERPRICING OF INITIAL PUBLIC OFFERINGS

In this paper, the pricing of initial public offerings (IPOs) is examined from the underwriter's point of view. It is shown that because of the regulations and procedures governing the underwriting and pricing of IPOs, underwriters can maximize expected income by underpricing IPOs. Thus, it is argued that in addition to other feasible explanations of the underpricing phenomenon (e.g., compensation to uninformed investors, insurance against legal liability, etc.), regulatory and procedural factors contribute to the underpricing of IPOs. This is shown to be true both when uninformed investors are present and absent from the market for IPOs.     

Regulatory underpricing: Determinants of Chinese extreme IPO returns

The Chinese stock market with its unique institutions is rather different from western stock markets. The average underpricing of Chinese IPOs is 247%, the highest of any major world market. We model this extreme underpricing with a supply-demand analytical framework that captures critical institutional features of China's primary market, and then empirically test this model using a sample of 1377 IPOs listed on the Shanghai and Shenzhen Stock Exchanges between 1992 and 2004. We find that Chinese IPO underpricing is principally caused by government intervention with IPO pricing regulations and the control of IPO share supplies. Besides the regulatory underpricing, this paper also documents some specific investment risks of IPOs in China's stock market.     

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.     

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.     

Underpricing of Chinese A-share IPOs and short-run underperformance under the approval system from 2001 to 2005

This paper analyses underpricing and short-run underperformance of the Chinese A-share IPOs from Mar, 2001 to 2005 when the new approval system was adopted. We find that the average market adjusted first-day return is 93.49% in this period, a more reasonable level when compared with those in previous periods in China. The findings show that underpricing in this period is significantly affected by offering mechanisms and inequality of demand and supply of IPOs. The effect of shareholder's structure is tested in the model and state-owned share's weight is shown to increase the degree of underpricing. Meanwhile, this paper analyses IPOs' short-run underpricing on their 10th, 20th, 30th trading days. It is found that most IPOs' underpricing shrinks and the degree of shrinking degrees is different across the groups categorized by offering mechanisms. Further, the underperformance of IPOs which are underwritten by more prestigious underwriters shows a comparatively lower range and is less severe in the short-run.     

How Much Do REITs Pay for Their IPOs?

Previous studies have documented the reversal in the initial returns of REIT IPOs from overpricing in the 1980s to underpricing in the 1990s. We find that the gross spreads of REIT IPOs decreased significantly in the 1990s. In particular, there is a bimodal clustering for gross spreads at 6.5 and 7.0%. Moreover, in the 1980s around 94% of REIT IPOs had integer offer prices, most of which were priced at either $10 or $20. However, the proportion of integer offer prices decreased to 64% in the 1990s. Higher gross spreads, overpricing, and high frequency of integer offer prices for REIT IPOs in the 1980s are consistent with the marketing hypothesis that in the 1980s REIT IPOs were mainly marketed to less-informed individual investors. Our results explain the dynamic process employed by underwriters in the setting of gross spreads and the pricing of REIT IPOs as a new financial product in response to various structural changes in REITs.     

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.     

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.     

Underpricing and long-term performance of IPOs in China

We study the underpricing and long-term performance of A- and B-share initial public offerings (IPOs) issued in China during the 1993–1998 period. The average underpricing for A- and B share IPOs are 178% and 11.6%, respectively. The underpricing of A-share IPOs is positively related to the number of days between the offering and the listing and the number of stock investors in the province from which the IPO comes, and negatively related to the number of shares being issued. None of these characteristics explain the underpricing of B-share IPOs. In the long run, A-share IPOs slightly underperform the size- and/or book/market (B/M)-matched portfolios while B-shares outperform the benchmark portfolios.     

Initial Public Offerings in Australia 1994 to 1999, Recent Evidence of Underpricing and Underperformance

This paper analyses whether financial and non financial characteristics of Australian initial public offerings (IPOs) can explain observed underpricing and long term underperformance over the period 1994 to 1999. A number of previous Australian studies have investigated initial day underpricing and longer term underperformance of IPOs and this study updates those papers. We find that initial day underpricing can in part be explained by market sentiment, forecast dividend per share yields, underwriter options and share options. Our longer term analysis supports the finding of previous studies in that IPOs on average, underperform the market in the first year following their listing.     

Why are IPOs underpriced? Evidence from Japan's hybrid auction-method offerings

We document discretionary underpricing and partial adjustment of IPO prices in the public offer tranche of Japan's hybrid auction regime, in which investor information differences are not important, there are no roadshows, preferential allocations are negligible, institutional investing is low, and the public offer tranche cannot fail. The magnitude and variation of underpricing in our sample, which spans relatively hot and cold markets, are similar to those reported for US IPOs. The evidence is most consistent with underpricing arising from an implicit contract to allocate risk related to initial mispricing where, in exchange for guaranteeing a minimum price, the underwriter participates indirectly in upside performance. The results raise important questions about interpretations of IPO underpricing in the US.
