Penny Stock IPOs

We examine underpricing, long-run returns, lockup periods, and gross spreads for penny stock IPOs over the 1990–1998 period. We find that penny stock IPOs have higher initial returns than ordinary IPOs, but significantly worse long-run underperformance. We also find that penny stock IPOs have longer lockup periods and larger gross spreads. To explore the effect of potential market manipulation, we examine IPOs led by a group of underwriters that were the subject of SEC enforcement actions and/or other penalties. Penny stock issues led by these banks are particularly underpriced and underperform ordinary IPOs led by other underwriters.     

The use of the comparable firm approach in valuing Australian IPOs

Despite the difficulty of finding comparable firms in a less populated market, we provide evidence on the usefulness of the comparable firm approach using 275 Australian industrial IPOs from 1993 to 2000. We show that, without adjustments, IPO price-earnings (P/E) and market-to-book (P/B) multiples based on management forecasts of earnings and book values of equities provided in prospectuses are strongly associated with the average P/E and P/B multiples of two comparable firms (matched on industry, growth and size). Additional tests show that the value estimated using the comparable firm approach (in the form of a P/V ratio, where P is the offer price and V is the estimated firm value) is associated with IPO underpricing.     

The use of undisclosed limit orders on the Australian Stock Exchange

This paper investigates the use of undisclosed limit orders on the Australian Stock Exchange (ASX). Our findings suggest that undisclosed limit orders are used to reduce the option value of limit orders. We find no evidence that undisclosed limit orders are more frequently used by informed traders than disclosed limit orders. The effects of recent changes in undisclosed order regulation are also examined. We find that the enhancement in pre-trade transparency, through tightening the undisclosed order regulation in October 1994, resulted in a significant decline in trading volume. The impact of the second regulation change in October 1996, which further tightened undisclosed order regulation, resulted in a less significant trading volume reduction.

The underpricing of IPOs on the Stock Exchange of Mauritius

This paper investigates the underpricing of IPOs on the Stock Exchange of Mauritius (SEM). Taking into account the whole population of firms which went public since the inception of the SEM until 2010, the results show an average degree of underpricing within the range 10–20%. Using a regression approach, we demonstrate that the aftermarket risk level and auditor's reputation both have a significant positive impact on initial returns. We propose the use of the Z-score as a composite measure of a firm's ex ante financial strength, and find that it has a significant negative effect on the degree of short-run underpricing.     

Bookbuilding,the option to withdraw,and the timing of IPOs

The ability to withdraw IPOs when demand is weak increases expected proceeds and provides issuers with option value. To enhance this value, the SEC adopted in 2001 the ‘public-to-private’ safe harbor Rule 155 and simplified Rule 477 for withdrawing offerings. The option value can exceed the underpricing associated with soliciting investor demand. Hence, issuers might prefer bookbuilding despite the associated underpricing even if they could sell via fixed price at full expected value. The option value increases faster than underpricing with ex ante uncertainty, generating predictions regarding the use of bookbuilding and the timing of IPOs, and leading to a distinct theory of hot IPO markets.     

Capital Gains Taxation and Stock Market Activity: Evidence from IPOs

Prior to the Tax Reform Act of 1986 (TRA '86), long-term capital gains were taxed at a lower rate than short-term gains, presenting investors with an opportunity to increase their after-tax return by delaying the sale of appreciated assets until after they qualified for long-term status and selling depreciated assets prior to long-term qualification. Using a sample of Initial Public Offerings, I find that stocks that appreciated prior to long-term qualification exhibit increased volume and decreased returns just after their qualification date, while stocks that depreciated prior to long-term qualification exhibit these effects just prior to their qualification date.

Stock price clustering on option expiration dates

This paper presents striking evidence that option trading changes the prices of underlying stocks. In particular, we show that on expiration dates the closing prices of stocks with listed options cluster at option strike prices. On each expiration date, the returns of optionable stocks are altered by an average of at least 16.5 basis points, which translates into aggregate market capitalization shifts on the order of $9 billion. We provide evidence that hedge rebalancing by option market makers and stock price manipulation by firm proprietary traders contribute to the clustering.     

Determinants of stock option use by Japanese companies

Japanese data show a negative relation between leverage and the probability of firms' use of stock options. Such a relation is more marked for firms affiliated with specific keiretsu or main banks. This evidence reflects the fact that Japanese companies are more reliant on debt financing and that the agency cost of debt is a central issue in corporate governance. Results show that the frequency of the firms' use of stock options is positively associated with firm size. Finally, independent firms, which reveal more concern about shareholder wealth, are more likely to use stock options.     

The benefits of option use by mutual funds

Based on comprehensive regulatory data on equity mutual fund option use from the SEC's N-SAR filings, we are the first to present consistent evidence that equity funds' option use generates higher risk-adjusted performance. We further show that this is a direct effect of option use and not an indirect effect of other fund characteristics. Option use also directly results in lower systematic risk, as funds show significantly lower market betas during periods of options usage. Finally, mutual funds use options mainly for hedging as they primarily use protective puts and covered calls. These results are independent of known phenomena, such as the low beta anomaly, and robust to tests for endogeneity and a novel 5-factor model including an investable option strategy factor (IOS). Overall, our findings show that mutual fund option use is beneficial to investors and does not pose risk to the financial system as feared by the SEC. Our results are thus important for investors as well as regulators.     

Stock price decreases prior to executive stock option grants

This study examines abnormal stock price changes prior to executive stock option grants. Executives have the incentive and opportunity to manage the timing of their communications of inside information to the market during the period just prior to the date of their stock-option grant so as to reduce the exercise price of their options. Executives benefit from temporary stock price decreases before the grant date and by stock price increases after the grant date. Executive stock option grants create a unique opportunity for insiders to profit by manipulating the timing of information flowing to the market without engaging in insider trading. Using data on 783 stock-option grants to chief executive officers, we find a statistically significant abnormal decrease in stock prices during the 10-day period immediately preceding the grant date.     

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.     

Stock option grants to target CEOs during private merger negotiations

Unscheduled stock options to target chief executive officers (CEOs) are a nontrivial phenomenon during private merger negotiations. In 920 acquisition bids during 1999-2007, over 13% of targets grant them. These options substitute for golden parachutes and compensate target CEOs for the benefits they forfeit because of the merger. Targets granting unscheduled options are more likely to be acquired but they earn lower premiums. Consequently, deal value drops by $62 for every dollar target CEOs receive from unscheduled options. Conversely, acquirers of targets offering these awards experience higher returns. Therefore, deals involving unscheduled grants exhibit a transfer of wealth from target shareholders to bidder shareholders.     

Investment trust IPOs: Issuing behaviour and price performance Evidence from the London Stock Exchange

In this paper, we document an average first day return of 1.91 percent for the population of 105 investment trust IPOs during the period from January 1984 through August 1992 on the London Stock Exchange. This is the first study that finds evidence of significant first day returns for a sample of closed-end fund IPOs. The results also suggest that investment trust IPOs are subject to ‘hot’ issue periods. These tend to occur when there is a marked narrowing in the discounts of seasoned investment trusts. Initial gains are, however, short lived; by the end of their first year, investment trust IPOs substantially underperform a number of relevant benchmarks and, on average, trade at discounts to their underlying net asset values.     

Marketing Closed‐End Fund IPOs: An Analysis of the International Stock Funds

Various studies argue that underwriting fees are excessive and investment bankers prolong the price stabilization period in aftermarket trading of closed‐end fund (CEF) shares. The poor performance of these funds also raises questions about the financial sophistication of initial public offering (IPO) buyers. In this study, we examine these issues for a sample of international stock CEFs. Our findings indicate that underwriting fees are not excessive relative to industrial issues, and we do not find that investment bankers prolong the stabilization period to camouflage the underwriting cost. Our findings are consistent with earlier studies that discounts contribute significantly to the poor performance during the first six months of aftermarket trading.     

Competitive IPOs

Competition between investment banks for lead underwriter mandates in IPOs is fierce, but having committed to a particular bank, the power of the issuer is greatly reduced. Although information revelation theories justify giving the underwriters influence over pricing and allocation, this creates the potential for conflicts of interest. In this clinical paper we analyse an interesting innovation that has been used in recent European IPOs whereby issuers separate the preparation and distribution roles of investment banks, and keep competitive pressure on the banks throughout the issue process. These 'competitive IPOs' allow the issuer greater control and facilitate more contingent fee structures that help to mitigate against 'bait and switch.' But unlike more radical departures from traditional bookbuilding – such as auctions – the competitive IPO is an incremental market-based response to potential conflicts of interest that retains many of the advantages of investment banks' active involvement in issues.     

Merger-Motivated IPOs

In this paper, we find support for initial public offerings (IPOs) motivated by subsequent acquisition activity. Over a third of newly public firms enter the market for corporate control as acquirers within three years of the IPO. We find that IPOs facilitate acquisitions in a number of ways. Newly public firms benefit from the cash raised in the IPO, from subsequent access to public financing, and from ability to pay with publicly traded stock for acquisitions. IPO firms also benefit by obtaining market feedback and by taking advantage of high post-IPO stock values in making stock-based acquisitions at favorable terms.     

Zero-revenue IPOs

Information-based models of the IPO decision suggest that going public before having generated revenues is inefficient. Still, 15% of firms going public in Europe have not reported revenues prior to the IPO. This paper investigates why these firms decide to conduct an IPO and examines whether the absence of revenues affects the outcomes of this decision. The evidence shows that zero-revenue firms go public to fund investments, mainly in the form of R&D. However, their shares are more underpriced at the IPO and develop less liquid and more volatile aftermarket trading than those of revenue-generating issuers. These effects are driven by firms whose revenue-less status is more persistent, as 18.6% still report no revenues at their three-year IPO anniversary. Also, zero-revenue issuers face a higher risk of being delisted shortly after the IPO. Overall, the evidence indicates that zero-revenue firms go public in an attempt to fund superior growth opportunities, but the high levels of information asymmetry and uncertainty increase the cost of raising capital and the risk of an early delisting.     

Effects of taxation for option writers: an Australian perspective

Writing an option is a taxable event for Australian investors. This method of taxation penalizes investors who hold open short option positions over the tax year end by accelerating their tax liability relative to the timing of the economic gain from writing options. This paper examines the levels of open interest in the Australian Stock Exchange over the change in financial year to determine whether investors time their transactions to avoid this tax acceleration. The results show that level of open interest is lower in the last month of the financial year after controlling for non‐tax determinants of option demand.
