An Investigation of Market Microstructure Impacts on Event Study Returns

We investigate the importance of bid-ask spread-induced biases on event date returns as exemplified by seasoned equity offerings by NYSE listed firms. We document significant negative return biases on the offering day which explain a large portion of the negative event date return documented in the literature. Buy-sell order flow imbalance is prominent around the offering and induces a relatively large spread bias. If order imbalances are suspected, the researcher can use returns calculated from the midpoint of the closing bid and ask quotes instead of returns calculated from closing transaction prices to avoid this return bias.     

VALUATION EFFECT OF ISSUING NONSUBORDINATED VERSUS SUBORDINATED DEBT

Recent studies analyzing stock market reaction to announcements of straight debt offerings report, in general, insignificant abnormal stock returns. In this study we examine the effect of debt seniority on market reaction. The evidence shows weakly positive abnormal returns upon the announcements of nonsubordinated straight debt offerings. In contrast, announcements of subordinated straight debt offerings induce significantly negative abnormal returns. Our findings generally support the information release hypothesis.     

Return and risk in initial public offerings of both shares and warrants

In the past few years there has been an increasing number of new issues of shares of common stock together with warrants intended to raise interest in initial public offerings of relatively young, growing firms. In this study we examine the pricing efficiency of stocks and warrants offered simultaneously to the public as a single unit. We present a model for evaluating the warrants in such offerings and test it empirically against data from the Tel-Aviv Stock Exchange, where such offerings have become standard. We find that the issued units are usually undervalued, allowing for significant abnormal positive returns. But, while the warrants are usually underpriced, the stocks are overpriced. Largely consistent with the evidence from other financial markets around the world, we also find abnormal negative rates of return in the long run.     

Institutional Shareholder Investment Horizons and Seasoned Equity Offerings

Firms with more short‐term institutional shareholders experience significantly more negative abnormal returns at the announcement of seasoned equity offerings. This effect is strong for primary offerings (only firms receive proceeds), but is not present for secondary offerings (firms do not receive any proceeds). Furthermore, a shorter institutional shareholder investment horizon predicts poorer postissue abnormal operating performance and the negative effect of a shorter shareholder horizon is mitigated by higher managerial ownership. My results are consistent with the argument that long‐term shareholders more carefully monitor managerial activities and prevent misuse of the cash flow provided by equity issues.     

Rights Offerings and Expropriation by Controlling Shareholders

We investigate rights issues and open offers in Hong Kong. We observe that the greater the severity of firms’ management‐agency problems, the more unfavourably shareholders tend to react, leading to more negative cumulative abnormal returns or rights forfeiture. Controlling shareholders do not forfeit rights, and may increase their percentage ownership at deep price discounts by underwriting rights offerings. Our results suggest that, although certain rights offerings can be described as value‐enhancing, many other rights offerings closely resemble the expropriation activities of controlling shareholders.     

Market reaction to “unsweetened” and “sweetened” rights offerings in an emerging European stock market

This research investigates the market reaction to both “unsweetened” (plain) and “sweetened” (with simultaneous distribution of bonus issues) rights offerings in the Istanbul Stock Exchange. Consistent with previous U.K. and U.S. evidence, although with larger magnitude, the announcement day abnormal returns for “unsweetened” rights offerings are negative and significant, suggesting that such issues convey unfavorable information about the future operating performance, investment opportunities, liquidity and dividend policy. In contrast, for “sweetened” rights offerings, the abnormal returns are positive. The empirical results do not provide evidence for the enhanced trading liquidity effect (the “sweetener” split effect) and for the overvaluation signaling effect.     

Pseudo Market Timing and the Long-Run Underperformance of IPOs

Numerous studies document long-run underperformance by firms following equity offerings. This paper shows that underperformance is very likely to be observed ex-post in an efficient market. The premise is that more firms issue equity at higher stock prices even though they cannot predict future returns. Ex-post , issuers seem to time the market because offerings cluster at market peaks. Simulations based on 1973 through 1997 data reveal that when ex-ante expected abnormal returns are zero, median ex-post underperformance for equity issuers will be significantly negative in event-time. Using calendar-time returns solves the problem.     

Why are convertible bond announcements associated with increasingly negative issuer stock returns? An arbitrage-based explanation

While convertible offerings announced between 1984 and 1999 induce average abnormal stock returns of −1.69%, convertible announcement effects over the period 2000–2008 are more than twice as negative (−4.59%). We hypothesize that this evolution is attributable to a shift in the convertible bond investor base from long-only investors towards convertible arbitrage funds. These funds buy convertibles and short the underlying stocks, causing downward price pressure. Consistent with this hypothesis, we find that the differences in announcement returns between the Traditional Investor period (1984–1999) and the Arbitrage period (2000–September 2008) disappear when controlling for arbitrage-induced short selling associated with a range of hedging strategies. Post-issuance stock returns are also in line with the arbitrage explanation. Average announcement effects of convertibles issued during the Global Financial Crisis are even more negative (−9.12%), due to a combination of short-selling price pressure and issuer, issue, and macroeconomic characteristics associated with these offerings.     

The information content of insider trading around seasoned equity offerings

This paper examines insider trading around seasoned equity offering (SEO) announcements in Hong Kong. The announcements of private placings (rights offerings) are associated with positive (negative) abnormal stock returns. However, longer-term stock returns are negative for both private placings and rights offerings. In general, insiders are net purchasers in placing firms in the 6 months prior to and 6 months subsequent to the SEO, whereas insiders are net sellers in rights issue firms in the 6 months prior to and 6 months subsequent to the issue. The net purchases made by the insiders of firms making placements help them maintain their control rights, which are otherwise diluted by the placements. Insider trading does not explain longer-term investment returns.     

Three Decades of IPO Markets in Canada: Evolution,Risk and Return

This article explores the extent that the long‐run returns following initial public offerings (IPOs) can explain the asserted decrease in IPOs in Canada. The causes of such a decrease remain controversial, in part because of our limited knowledge of this market. We first describe in detail the evolution of Canadian IPOs on the senior and the venture stock exchanges over three decades (1986–2016). This evolution differs considerably between natural resource and non‐natural resource firms. Second, using other junior markets as a benchmark, we show that the Canadian IPO market is very particular, mainly because it lists very small firms at an early development stage. Third, using 2,145 Canadian IPOs, we provide evidence that these IPOs generate three‐year negative average abnormal returns, and more than 70 percent report negative abnormal returns. Large issuers reporting profits constitute the only subsample that provides fair returns, but they account for less than 5 percent of IPOs. Such a market probably survived for many decades because of investors' preference for skewness and the characteristics of the returns' distribution. We observe a high level of skewness of abnormal returns, consistent with the behavioral finance proposition that investors are often unduly optimistic when valuing lottery stocks.     

The Wealth Effects of Private Stock Placements under Regulation D

This paper examines the wealth effects associated with unregistered private common stock placements under the Regulation D exemption by a sample of exchange listed and over the counter firms. Unlike the negative abnormal returns associated with public equity offerings, private placements of common stocks under Regulation D are initially associated with significantly positive abnormal returns. However, these firms experience significant negative price effects in the two years following the private placements.     

Announcement effects of convertible bond loans and warrant-bond loans: An empirical analysis for the Dutch market

This study investigates the announcement effects of offerings of convertible bond loans and warrant-bond loans using data for the Dutch market. The event study analysis shows that announcement effects of convertible bonds are associated with positive but insignificant abnormal returns and that announcements of warrant-bonds are associated with significant positive abnormal returns. These findings are similar to the results for Japanese hybrid debt, as reported by Kang et al. (1995) (Kang, J.K., Kim, Y.C., Park, K.J., Stulz, R.M., 1995. Journal of Financial and Quantitative Analysis, pp. 257–270) and Kang and Stulz (1996) (Kang, J.K., Stulz, R.M., 1996. Review of Financial Studies, pp. 109–139), but they contrast with studies for the United States that generally find significant negative abnormal returns for convertible bond loans and insignificant negative abnormal returns for warrant-bond loans. Our results cannot be attributed to differences in the corporate governance structures of the Netherlands and the United States. We find that the positive abnormal returns for the warrant-bond loans are caused by the packaging of the announcements with other (good) firm-specific news.     

媒体关注度对新股表现的影响——来自中国股票市场的证据

新闻媒体对证券投资的影响日趋重要,它会通过影响投资者的心理和行为而影响资产价格。首次公开发行的股票（IPOs）由于倍受媒体关注,从而会在上市以后的价格表现上产生一定的影响。本文选取2006年6月至2008年6月上市的246只首次公开发行的股票作为样本,以百度新闻搜索到包含股票名称的新闻数量作为媒体关注度的衡量指标,实证检验了媒体关注度对新股表现的影响。本文得出结论：媒体关注度通过影响投资者情绪,对新股短期累积超额收益产生正的影响,而对长期累积超额收益产生负的影响。同时发现,媒体关注度高的新股,其发行价格也相对较高。     

Recapitalization of one class of common stock into dual-class: Growth and long-run stock returns

We study a sample of 178 firms that changed from a one-share one-vote into a dual-class common stock structure during 1979–1998. We find that dual-class recapitalizations are shareholder value enhancing corporate initiatives. Using accounting data, Lehn et al. (1990) [Lehn, K., Netter, J., Poulsen, A., 1990. Consolidating corporate control: dual-class recapitalizations versus leveraged buyouts. Journal of Financial Economics 27, 557–580] provide evidence that dual-class recapitalizing firms grow faster than firms in a control group and undertake secondary equity offerings (SEOs) to finance growth. We show that growth is indeed beneficial to the shareholders. The stockholders, on average, earn significant positive abnormal returns of 23.11% in a period of 4 years following the announcement month. Furthermore, abnormal returns are even larger (52.61%) for the dual-class firms that issue equity. This evidence is especially supportive of the value enhancing hypothesis as it is contrary to the prevailing result that SEOs are generally followed by large negative returns. We do not find any evidence of managerial entrenchment.     

Performance of Malaysian IPOs: Underwriters reputation and management earnings forecasts

This paper examines the financial performance of Malaysian initial public offerings (IPOs) during the period 1980–1995. The major focus of the study is on the role of management earnings forecasts and underwriters in the valuation of IPOs. The results suggest extremely high and statistically significant initial premiums and positive and statistically significant long-term returns up to 3 years after listing. The findings for long-term returns contradict the consensus of the IPO literature that documents a significant negative long-term performance. Our results indicate a negative association of upward bias in management earnings forecasts with IPOs' performance during the first 12 months after the IPOs.     

The IPO Derby: Are There Consistent Losers and Winners on This Track?

We examine the individual and joint relation of discretionary accounting accruals, underwriter reputation, and venture capital backing with the long-run performance of initial public offerings (IPOs). We find that although correlated to some extent, these variables do not manifest the same underlying phenomena in their relation to IPOs' performance. The confluence of the variables is more important than using any one of them individually to identify IPOs that exhibit abnormal long-run stock returns. The combination of their negative aspects helps identify extreme underperformers. We also identify a set of winner IPOs by combining the positive aspects of the three variables.     

An empirical investigation of whether Australian capital gains tax reforms influence individual investor behaviour

This paper examines whether an asset's qualification for discounted tax treatment is associated with positive abnormal trading volumes and negative abnormal returns, as would be predicted if investors modified their behaviour to reduce their tax liability. Our examination of 152 initial public offerings (IPOs) documents that there is an incremental increase in abnormal trading volume for those IPOs that have experienced a significant increase in price since listing over those IPOs that have increased only marginally. Although we provide only limited evidence to suggest that this increase in trading volume is accompanied by a decrease in returns, this is not unexpected in a market that has anticipated this type of behaviour by the relatively small proportion of individual investors able to benefit from the discounted tax treatment.     

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.     

Initial Public Offerings: CFO Perceptions

We examine four issues pertaining to initial public offerings (IPOs) using a survey of 438 chief financial officers (CFOs). First, why do firms go public? Second, is CFO sentiment stationary across bear and bull markets? Third, what concerns CFOs about going public? Fourth, do CFO perceptions correlate with returns? Results support funding for growth and liquidity as the primary reasons for IPOs. CFO sentiment is generally stationary in pre‐ and post‐bubble years. Managers are concerned with the direct costs of going public, such as underwriting fees, as well as indirect costs. We find a negative relation between a focus on immediate growth and long‐term abnormal returns.
