Noise from online discussion forums: Evidence from IPOs in China

In this study, we use initial public offerings (IPOs) in China to investigate how online stock forums influence information asymmetry and IPO valuation. The empirical analysis isolates the underpricing and overvaluation components of initial returns. The number of forum comments, postings, and readings are positively associated with initial returns and the degree of underpricing, implying that forums create noise that exacerbates information asymmetry during IPOs. This effect is amplified by the quiet period regulation, which drives investors to rely on online discussion forums to obtain information. Through sentiment analyses of forum posts and media coverage, we find that the negative effect of online forums is more prominent when bad news prevails. We clarify the role of online stock forums in IPO pricing and information asymmetry by separating underpricing from overvaluation in initial returns.     

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.     

Liquidity Benefits from IPO Underpricing: Ownership Dispersion or Information Effect

The positive correlation between initial underpricing and liquidity in the secondary market several months after an initial public offering (IPO) has previously been attributed to ownership dispersion induced by underpricing. We find that public information production is another channel by which underpricing improves liquidity. Using a sample of IPOs from Euronext, we find that analyst coverage engendered by initial underpricing reduces information asymmetry costs and illiquidity in the secondary market. The impact of information asymmetry is statistically more significant on measures based on adverse selection costs than on those based on the proportion of informed traders in the market.     

Narcissistic managers and IPO underpricing

Using hand-collected data on the signature size of managers in Chinese initial public offerings (IPOs) from 2007 to 2019 as a proxy for managerial narcissism, we examine how IPOs with narcissistic managers (narcissistic IPOs) affect IPO underpricing. The findings suggest that narcissistic IPOs have higher underpricing than non-narcissistic IPOs. Specifically, we find that on average, a narcissistic IPO exhibits approximately 11.3% higher underpricing than a median IPO firm. Our results are robust to alternative metrics of narcissism and underpricing after controlling for endogeneity. Additional analyses suggest that narcissistic IPOs are more likely to engage in earnings management than non-narcissistic IPOs. The former exhibits excessive risk-taking behavior, gauged by earnings volatility pre-IPO and a higher beta post-IPO. In the cross-sectional analyses, we document that the impact of managerial narcissism on IPO underpricing is more salient for IPOs facing unsophisticated investors, high market sentiment, or poor corporate governance.     

Country-level Accounting Enforcement and IPO Underpricing

Using a sample of up to 2,503 initial public offerings (IPOs) in 32 countries from 2011–2017, we predict and find that higher levels of country-level accounting enforcement are associated with lower levels of IPO underpricing. IPOs in countries with a relatively low accounting enforcement score (second quintile) exhibit a mean underpricing of 19%, whereas the mean underpricing amounts to just 9% in countries with a relatively high score (fourth quintile). The results remain qualitatively the same when we employ a multi-level model or a difference-in-difference design. In countries that substantially strengthened their accounting enforcement in the 2003–2009 period, the level of IPO underpricing decreased significantly. We show that accounting enforcement matters for the cost of going public.     

The effects of R&D, venture capital, and technology on the underpricing of IPOs in Taiwan

Information asymmetry and value uncertainty causes high -research and development (R&D) or high-tech Initial Public Offerings (IPOs) to become underpriced. Venture capital can serve as a moderator to mitigate the information asymmetry and value uncertainty to reduce IPO underpricing. High-tech industries significantly contribute to Taiwan??s economic growth. With the unique Taiwan data, we find that venture-backed IPOs are less underpriced. More importantly, IPO underpricing due to technology decreases with the use of venture capital and decreases with the interaction between R&D expenditure and technology. Technology requirement reduces the underpricing of high-R&D IPOs. Accordingly, R&D spending reduces the underpricing of high-tech IPOs.     

IPO Underpricing and After-Market Liquidity

The underpricing of initial public offerings (IPOs) is generallyexplained with asymmetric information and risk. We complementthese traditional explanations with a new theory where investorsworry also about the after-market illiquidity that may resultfrom asymmetric information after the IPO. The less liquid theaftermarket is expected to be, and the less predictable itsliquidity, the larger will be the IPO underpricing. Our modelblends such liquidity concerns with adverse selection and riskas motives for underpricing. The model’s predictions aresupported by evidence for 337 British IPOs effected between1998 and 2000. Using various measures of liquidity, we findthat expected after-market liquidity and liquidity risk areimportant determinants of IPO underpricing.     

A Review of IPO Activity, Pricing, and Allocations

We review the theory and evidence on IPO activity: why firms go public, why they reward first–day investors with considerable underpricing, and how IPOs perform in the long run. Our perspective is threefold: First, we believe that many IPO phenomena are not stationary. Second, we believe research into share allocation issues is the most promising area of research in IPOs at the moment. Third, we argue that asymmetric information is not the primary driver of many IPO phenomena. Instead, we believe future progress in the literature will come from nonrational and agency conflict explanations. We describe some promising such alternatives.     

Venture Capital Valuation,Partial Adjustment,and Underpricing: Behavioral Bias or Information Production?

Using a sample of venture capital (VC)‐backed initial public offerings (IPOs), we analyze the role played by perceived valuation changes on IPO underpricing. We find that perceived valuation change from the last pre‐IPO VC round to the IPO affects IPO underpricing in a nonlinear way. Further analysis indicates that information‐based theories, not behavioral biases, explain this nonlinearity. We also find that the previously documented partial adjustment effect and its nonlinear impact on IPO underpricing are related to the trajectory of the perceived valuation changes, which stands in stark contrast to prior evidence of the importance of behavioral biases.     

The pricing and performance of IPOs in China’s poor counties

In the context of China’s drive to alleviate poverty, we focus on the initial public offering (IPO) firms located in China’s poor counties and investigate their IPO pricing and post-IPO performance. Contrary to the findings reported for the U.S., we find that the problem of information asymmetry between Chinese firms located in rural areas and their investors is so severe that these IPO firms are associated with significantly higher underpricing. This effect is more pronounced for firms located in rural areas with poor traffic systems. We do not find significant market performance differences between rural and urban firms after their IPOs, but the operating performance of rural firms improves in the short term. Our additional analyses indicate that rural IPO firms have significantly lower investor attention and higher agency costs than urban firms. Overall, we enrich the literature on IPO pricing and the economic effects of geographic location.     

Property rights and access to equity capital in China

This study uses recent improvements to China's physical and intellectual property protections to test information asymmetry, signaling, and litigation risk theories of initial public offering (IPO) underpricing. We find robust evidence that stronger physical and intellectual property protections are associated with lower initial returns, especially among smaller IPOs and non-equity carve-outs. This result is consistent with the notion that property rights reduce information asymmetry among IPO participants; however, some of China's reforms, including the 2014 establishment of specialized intellectual property courts in Beijing, Shanghai, and Guangzhou, appear to have increased litigation risk. Additional tests indicate that property rights positively impact the likelihood that an IPO firm is backed by venture capital. Overall, these results are consistent with the idea that strong property rights help alleviate the adverse selection problem that results from information asymmetry among firms and equity investors.     

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.     

Signaling in the Internet craze of initial public offerings

We explain the clustering of underpricing in initial public offerings (IPOs). The model features an industry with aggregate demand uncertainty and asymmetric information about firms' quality. In the IPO market, firms can signal quality by underpricing or under-issuing new shares. Expected aggregate demand for the industry's products increases with the publicity that the industry creates through IPO underpricing. We show that asymmetric information and expectations on aggregate product demand interact with each other to generate multiple equilibria. Underpriced IPOs cluster in one equilibrium but not in the other. We use these results to explain why the clustering often occurs in particular industries, is short-lived, and is sensitive to economic conditions.     

Do regulatory changes affect the underpricing of European IPOs?

We use a sample of 3677 European IPOs during the period 1998–2012 to examine how the adoptions of corporate governance codes by Member States of the European Union (EU) have affected IPO underpricing on Member State-regulated markets, where issuers are subject to corporate governance rules instituted by Member States, relative to a control sample of IPOs on exchange-regulated markets, where issuers are exempt from Member State corporate governance codes. Using this control sample approach facilitated by the existence of second-tier, exchange-regulated markets in the EU, we find that, on average, IPO underpricing declined on Member State-regulated markets after Member States adopted corporate governance codes containing SOX-like provisions. We do not find a similar reduction in IPO underpricing on exchange-regulated markets. Our results are robust to alternative specifications, and our findings support the view that elevating corporate governance standards increases transparency and reduces information asymmetries that affect IPO valuations.     

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).     

Industrial Diversification and Underpricing of Initial Public Offerings

The initial public offerings (IPOs) of diversified firms, those reporting more than one business segment at the time they go public, experience less underpricing than do IPOs by focused issuers. We explore two explanations for this phenomenon. Diversification may benefit IPO firms by reducing information asymmetries and therefore, lowering underpricing costs. Alternatively, high quality focused firms may be signaling their value by underpricing their shares to a greater degree. Though we find at least some evidence consistent with each explanation, a majority of the evidence favors signaling.     

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.     

Fixed price and book building methods in an exogenous environment: Evidence from Indonesia stock market

Book building has become a popular method of selling new shares. Although previous models suggest that book building is an efficient method for price discovery in initial public offering (IPO) issuance, empirical evidence provides mixed results. Previous empirical findings on IPO methods have been obtained from markets that allow issuers to choose the IPO method, and this setting is not free from endogeneity issues. We investigate the effect of IPO method (fixed price vs book building) in Indonesia, which is an emerging market that offers an exogenous setting for IPO methods. More specifically, Indonesia used the fixed price method for IPOs before October 2000 and used the book building method thereafter following the introduction of new IPO regulations. Using estimation methods that consider clustering phenomena, we find that book building yields larger underpricing and greater volatility than the fixed price method. Moreover, a positive relationship is observed between underpricing and aftermarket volatility for the book building method and book building IPOs underperform fixed price IPOs. No relationship was observed between underpricing and long-term performance for book building IPOs. Compared with previous models, our findings suggest that book building does not represent a quality IPO method and suffers from agency conflict; thus, this method needs improvement.
