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.     

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.     

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.     

An examination of IPO secondary market returns

IPO stock prices increased approximately 2.3% on the first day of secondary market trading over the period 1993 through 2003. While these aftermarket returns are accentuated during 1999 and 2000, they persist after the bubble burst and even increase as a percentage of total underpricing. We explore several non-mutually exclusive hypotheses to explain our findings including price support, laddering, retail sentiment, and information asymmetry. Our results are most consistent with the view that higher secondary market returns accrue to IPOs with more information asymmetries possibly due to price and aggregate demand uncertainty.     

Issuer IPO underpricing and Directed Share Program (DSP)

The issuer underpricing hypothesis addresses why IPOs with a Directed Share Program (DSP) are substantially more underpriced and why the issuers are not upset over the additional money left on the table. In support of the hypothesis, we find that both the final size and likelihood of DSP adoption are greater when expected IPO underpricing is high. Issuers with a DSP also strategically underprice their IPO through a downward bias in offer price adjustments, but will do so only when the cost is not prohibitive. Finally, the first-day IPO return is relatively higher when directed shares are allocated to customers.     

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.     

Auctions versus book-built IPOs in Japan: A comparison of aftermarket volatility

In a recent theoretical paper, Sherman [Sherman, A.E., 2005, Global trends in IPO methods: Book building versus auctions with endogenous entry, Journal of Financial Economics 78, 615–649.] proposes that: “If book building leads to greater expected underpricing relative to uniform price or discriminatory auctions, then it should also lead to less volatility in aftermarket trading…”. In this paper, we study a Japanese sample and find that book-built IPOs exhibit greater underpricing and higher aftermarket volatility compared to price-discriminatory auctions. Aftermarket volatility wanes with seasoning in both sub-samples, but the book-built volatility levels are persistently higher than those for auctions for as long as one year after the IPO issue date.     

Post-IPO Directors' Sales and Reissuing Activity: An Empirical Test of IPO Signalling Models

Signalling models of IPO underpricing argue that owners of high-quality firms signal firm quality by underpricing shares sold at the IPO and retaining a large equity stake because they benefit from IPO signalling by selling further shares in the aftermarket at a higher share price. This hypothesis is tested by examining whether the probabilities and volumes of subsequent share issues or insider sales are related to the proposed IPO signals. There is evidence that post-IPO share issuance is related to initial returns, but the same is not true for insider selling. Moreover, little evidence is found to support the view that the proportion of equity retained by initial owners is an IPO signal. Therefore, the signalling hypothesis is rejected.     

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.     

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.     

Valuing and pricing IPOs

This paper investigates how underwriters set the IPO firm’s fair value, an ex-ante estimate of the market value, using a unique dataset of 228 reports from French underwriters. These reports are issued before the IPO shares start trading on the stock market and detail how underwriters determined fair value. We document that underwriters often employ multiples valuation, dividend discount models and discounted cash flow (DCF) analysis to determine fair value but that all of these valuation methods suffer from a positive bias with respect to equilibrium market value. We also analyze how this fair value estimate is subsequently used as a basis for IPO pricing. We report that underwriters deliberately discount the fair value estimate when setting the preliminary offer price. Part of the intentional price discount can be recovered by higher price updates. We find that, controlling for other factors such as investor demand, part of underpricing stems from this intentional price discount.     

Differences of opinion,institutional bids,and IPO underpricing

Miller (1977) hypothesizes that IPO underpricing arises because the issue price is based on the average opinion while the aftermarket price is set by a minority of optimistic investors. Using a unique data set of institutional bids for a large sample of Chinese IPOs, we show that the IPO issue price is positively related to the quantity-weighted average bid price and unrelated to the market-clearing bid price. In contrast, the first-day closing price is positively related to the market-clearing bid price and unrelated to the average bid price. Overall, our results provide strong support for Miller's explanation of IPO underpricing.     

Investor sentiment and the underperformance of technology firms initial public offerings

This research examines the effect of individual and institutional investor sentiment toward the overall market at the time of Initial Public Offering (IPO) on the aftermarket performance of technology IPO shares. The study which is based on 1346 U.S. technology IPOs completed between 1992 and 2009 shows that the irrational component of individual investor sentiment negatively affects shares’ aftermarket performance: the more optimistic individual investors are at the time of IPO, the lower the shares’ aftermarket return. On the other hand, the rational component of institutional investor sentiment does not affect the shares’ short-run performance, yet positively affects their long-run performance. In contrast with prior theoretical models this paper shows that investor overconfidence positively affects technology IPO shares’ aftermarket performance. The paper extends the behavioral finance literature by providing evidence on the negative role played by noise trading in affecting technology and biotechnology IPO shares performance.     

Global trends in IPO methods: Book building versus auctions with endogenous entry

The U.S. book-building method has become increasingly popular for initial public offerings (IPOs) worldwide over the last decade, whereas sealed-bid IPO auctions have been abandoned in nearly all of the many countries in which they have been tried. I model book building, discriminatory auctions, and uniform price auctions in an environment in which the number of investors and the accuracy of investors’ information are endogenous. Book building lets underwriters manage investor access to shares, allowing them to reduce risk for both issuers and investors and to control spending on information acquisition, thereby limiting either underpricing or aftermarket volatility. Because more control and less risk are beneficial to all issuers, the advantages of book building's allocational flexibility could explain why global patterns of issuer choice are surprisingly consistent. My models also predict that offerings with higher expected underpricing have lower expected aftermarket volatility; that an auction open to large numbers of potential bidders is vulnerable to inaccurate pricing and to fluctuations in the number of bidders; and that both book-built and auctioned IPOs will exhibit partial adjustment to both private and public information.     

Executive stock options and IPO underpricing

In about one-third of US IPOs between 1996 and 2000, executives received stock options with an exercise price equal to the IPO offer price rather than a market-determined price. Among firms with such “IPO options”, 58% of top executives realize a net benefit from underpricing: the gain from the options exceeds the loss from the dilution of their pre-IPO shareholdings. If executives can influence either the IPO offer price or the timing and terms of their stock option grants, there should be a positive relation between IPO option grants and underpricing. We find no evidence of such a relation. Our results contrast sharply with the emerging literature on managerial self-dealing at shareholder expense.     

Laddering IPO shares

Regulators, investors, and the financial media argue that underwriters tie Initial Public Offering (IPO) allocations to investor post-listing purchases in the issuer shares. Using unique data from the Oslo Stock Exchange (OSE) I investigate if these tie-in agreements are driven by price stabilization (reducing price falls below the offer price) or laddering (inflating prices above the offer price). I find that both stabilizing and laddering investors are rewarded with increased allocations for their service. However, only laddering investors increase allocations in very oversubscribed future issues. Secondary investors also lose from falling returns following laddering. I conclude that underwriters use both price stabilization and laddering across different IPOs. However, the rewards for cooperating investors and the economic consequences for secondary investors are much greater following laddering.     

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.     

Excess initial returns in IPOs

The empirical evidence on initial returns in IPOs reveals average overpricing as well as underpricing, depending on the type of security offered for sale. Consistent with this evidence, the present paper develops a model in which an IPO may be overpriced in equilibrium relative to its expected (or average) aftermarket price. Overpricing disappears, however, once the offer price is compared to a ‘float-weighted’ expectation, where the weights are given by the extent to which the number of securities that are floated in the offering (at the posted price) is positively related to the demand for allocations. Empirically, the model implies that equally-weighted returns underestimate initial returns in IPOs, and hence that inferences based on equally-weighted returns may be misleading.
