There is significant disagreement about whether, when, and why IPO firms manage earnings. We precisely identify the timing and motives behind earnings management by IPO firms. The period around an IPO is characterized by two events: the IPO itself and the lockup expiration. Both the raising of capital at the IPO and the exit by pre-IPO shareholders at lockup expiration create incentives for firms to manage earnings. To disentangle the effect of these events, we examine quarterly, rather than annual, abnormal accruals. We find no evidence of income-increasing earnings management before the IPO. However, IPO firms exhibit positive abnormal accruals in the quarter before and the quarter of the lockup expiration. Positive abnormal accruals are concentrated in less scrutinized firms and firms with high selling by pre-IPO shareholders. Moreover, we find that these accruals subsequently reverse and that such reversals contribute to long-run IPO underperformance.  相似文献

本文以2006—2016年上市的1397家公司为研究样本,实证检验了首日涨停板制度对新股解禁效应的影响。结果发现:首日涨停板制度实施期间发行的新股,解禁时有显著更差的市场表现,[-30,30]窗口期间的超额回报低至-8.43%,同时有更小的异常交易量和异常波动率;新股上市时股价高估程度越大、投资者情绪越高,首日涨停板制度对解禁效应的影响越强。上述结果支持了Hong et al.(2006)提出的"解禁与资产泡沫破灭"的理论,即首日涨停板制度导致新股发行后投机泡沫累积,投机泡沫破灭导致解禁时更大幅度的股价下跌。本文的研究结论补充了首日涨停板制度后果的文献,并对防范金融风险和完善新股市场化改革具有一定的政策参考价值。  相似文献

We document the determinants of short interest in newly public firms during the lockup period and how short interest influences the valuation effects surrounding lockup expiration. We find that the short interest is larger for stocks that have more downward price potential at lockup expiration. We also find that the stocks that are subjected to larger short positions experience more pronounced negative valuation effects upon lockup expiration. Finally, we find that the stocks with a larger short interest position just after lockup expiration experience weaker returns during the following the six-month period.  相似文献

This paper examines the hypothesis that the timing of lockup expiration is crucial to earnings management (EM) behavior in the period after an initial public offering (IPO). Taiwan's unique two-stage lockup regulations make the Taiwanese sample an excellent candidate for examining this hypothesis. Three main results are reached. First, we find positive discretionary accruals (DAs) from the IPO quarter to the quarter after the expiration of the first-stage lockup. The DA in the quarter of the second-stage lockup expiration is significantly positive. The evidence shows that the lockup provision is key in the findings of significant EM in the IPO year and the following year. We also find a positive association between DAs in first-stage lockups and subsequent insider selling activity, indicating that insiders' selling after lockup expiration accounts for EM in the lockup period. Third, the extent of EM in first-stage lockup is negatively related to that around the IPO, consistent with the reversal nature of DAs.  相似文献

Using a sample of IPO companies on the Shenzhen Small and Median Enterprise Board and the ChiNext Stock Market between 2005 and 2009, this paper analyzes the effect of venture capital participation on accounting information quality. We find that venture capitalists have a significant effect on earnings management, with reduced discretionary accruals before the expiration of the equity lock-up period and enhanced discretionary accruals after the expiration of the equity lock-up period. Our findings support the moral hazard hypothesis of venture capital, but not the certification/monitoring role of venture capital in IPOs. In addition, we find that venture capital plays a more important role in the earnings management of non-state-owned IPO companies than of state-owned companies.  相似文献

Corporate financial managers of biotech firms need long‐term financing to reach key milestones, and that requires a long‐ term capital structure. They must balance a mix of investors with different objectives and different investment horizons that includes traditional venture capitalists and also hedge funds and mutual funds. This study helps practitioners understand the complex role of exit decisions, as venture capitalists seek better exit strategies and performance. IPOs are financing but not “exit” moves. In addition to certifying firm value, insider purchasing of shares in the IPO offering has two major consequences. First, venture capitalists reallocate large sums of capital from early‐stage to late‐stage deals that are expected to have lower risk (but also lower expected return) and shorter time to exit. Second, the speed at which VCs exit after the IPO depends on the firm ownership structure after the IPO and the stock liquidity. Going public with a significant participation by venture capitalists will probably increase the post‐IPO ownership and decrease the free float of the stock, implying a delay of the exit and the realization of the capital gains from the investments. Although this study has focused exclusively on the biotechnology industry, insider participation is not unique to it. Biotech's venture brethren in the software and technology industries also have insider participation in IPOs. During 2003–2015, approximately 41 venture‐backed firms outside of the biotechnology sector had insider participation.  相似文献

Prospect and information‐momentum theories predict that insiders can offer fewer shares in an initial public offering (IPO) to create informational momentum and obtain higher prices in follow‐on offerings. I find that dilution and insider participation in the IPO are negatively related to the number and size of follow‐on offerings, consistent with the prediction. However, insider selling in follow‐on offerings is positively related to IPO selling, contrary to the theories. Returns around follow‐on offering announcements are more negative for newly public firms than older firms, but for newly public firms do not differ by whether the announcement comes before or after the lockup expiration date.  相似文献

新股破发是目前中国股市目前面临的一个重要现象。本文基于2004年至2010年上市的A股IPO,研究合资承销商对新股破发率的影响。研究发现,合资承销商所承销的新股破发率显著低于本土承销商。合资承销商的低破发率主要归功于更加有效且符合市场预期的一级市场发行定价能力,其表现为合资承销商发行的股票的短期市场价格相对发行价的偏离程度显著低于本土承销商发行的股票。另外,我们还发现合资承销商采取了一定的托市行为,该行为也减小了短期内新股跌破发行价的概率。本文的发现从新股发行的角度提供了开放金融市场对我国资本市场影响的新现象。  相似文献

This paper introduces an analysis of the impact of Legality on the exiting of venture capital investments. We consider a sample of 468 venture-backed companies from 12 Asia-Pacific countries, and these countries' venture capitalists' investments in US-based entrepreneurial firms. The data indicate IPOs are more likely in countries with a higher Legality index. This core result is robust to controls for country-specific stock market capitalization, MSCI market conditions, venture capitalist fund manager skill and fund characteristics, and entrepreneurial firm and transaction characteristics. Although Black and Gilson (1998) [Black, B.S., Gilson, R.J., 1998. Venture capital and the structure of capital markets: banks versus stock markets. Journal of Financial Economics 47, 243–77] speculate on a central connection between active stock markets and active venture capital markets, our data in fact indicate the quality of a country's legal system is much more directly connected to facilitating VC-backed IPO exits than the size of a country's stock market. The data indicate Legality is a central mechanism which mitigates agency problems between outside shareholders and entrepreneurs, thereby fostering the mutual development of IPO markets and venture capital markets.  相似文献

Block sales following IPOs are related to the IPOs' value relative to an estimate of intrinsic value, opening‐trade return, and IPO size. Overvalued IPOs experience more block sales than undervalued IPOs. IPOs with high block sales outperform IPOs with low block sales from 20 days after IPO through lockup expiration; however, IPOs with high block sales underperform IPOs with low block sales from lockup expiration through the third year after the IPO. The results indicate that block traders are advantaged relative to other traders; whether the advantage is based on superior information or superior valuation capabilities is unknown.  相似文献

This paper analyzes annual corporate governance decisions at firms making initial public offerings (IPOs) of common stock between 1996 and 1999. Our objective is to examine relations between firms' corporate governance decisions and the informativeness of available measures of managerial performance. We consider financial measures such as earnings and stock return, as well as direct monitoring. We collect a sample of IPO firms from the manufacturing, Internet, and technology (non-Internet) industries, and examine how the use of various performance measures in annual compensation grants and turnover decisions varies with the information environment of the firm and with the extent of venture capital influence. Consistent with prior research that finds earnings are of limited usefulness in firm valuation for Internet firms, we find Internet firms place less importance on earnings and greater importance on stock returns in determining compensation grants than do non-Internet firms. We also find that compensation grants of firms with little or no venture capital influence display significantly stronger association with accounting and stock performance measures than those of firms with more intense monitoring by venture capitalists. This result is consistent with direct monitoring and the use of explicit performance measures acting as substitute governance mechanisms.  相似文献

We analyze the effect of initial public offerings (IPOs) on industry competitors and provide evidence that companies experience negative stock price reactions to completed IPOs in their industry and positive stock price reactions to their withdrawal. Following a successful IPO in their industry, they show significant deterioration in their operating performance. These results are consistent with the existence of IPO‐related competitive advantages through the loosening of financial constraints, financial intermediary certification, and the presence of knowledge capital. These aspects of competitiveness are significant in explaining the cross‐section of underperformance as well as survival probabilities for competing firms.  相似文献

This study examines the impact of public venture capital (hereafter PVC) investments on corporate governance of initial public offering (hereafter IPO) firms in emerging markets. Using data collected from Taiwan PVC investments during 1996–2005, we analyse three corporate governance features in IPO firms: earnings management, board characteristics, and excess control by controlling shareholders. We find that PVC‐backed firms use fewer accounting accruals in their IPO financial statements than non‐PVC‐backed firms. This result suggests that PVC‐backed IPO firms engage in less earnings management than non‐PVC‐backed IPO firms. We also find PVC‐backed firms tend to set up their boards with fewer non‐independent directors and supervisors at IPO. This result indicates that PVC‐backed IPO firms have better board structures than non‐PVC‐backed IPO firms. Finally, we find that controlling shareholders are less likely to exert excess control in PVC‐backed firms than in non‐PVC‐backed firms. Overall, our results indicate that PVC investments add value to new IPO firms not only in financing their capital needs but also in creating better corporate governance structures in emerging markets.  相似文献

本文通过对比2009年7月1日至2014年6月30日IPO市场化定价发行阶段与2014年7月1日至2018年6月30日IPO限价发行阶段共1950个IPO样本,发现IPO限价发行对于新股在二级市场股价表现具有"弹簧效应":即抑制股票一级市场发行价格会造成新股在二级市场价格短期内超涨,限价发行新股的二级市场定价显著高于市场化定价发行新股的二级市场定价。限价发行引起的过高二级市场定价最终导致股票长期回报率低下。另外,创业板公司"弹簧效应"显著强于主板公司。这些实证结果都可以被本文提出的一级市场价格压抑造成二级市场非理性投资者上涨预期一致、盲目追涨的理论模型所解释。本文的研究指出抑制股票一级市场定价虽然形式上可以解决新股发行价过高问题,但是却造成二级市场更大的价格扭曲。这一发现为进一步完善我国IPO发行定价机制提供了依据。  相似文献

Previous research has determined that lockup provisions essentially defer sell-offs of shares by insiders, and therefore cause a pronounced decline in share price at the time the lockup provisions expire. However, some IPOs involve follow-on offerings that may allow some insiders to sell their shares before the lockup provision has expired. Our objective is to determine how follow-on offerings alter firm value above and beyond the typical lockup effects, and whether the effects are conditioned by firm-specific variables. We find that follow-on offerings elicit an average market response of 3.21% over a three-day period surrounding the filing date. In addition, the offerings experience adverse effects as of lockup expiration that are about 3.75% worse than other IPOs, after considering other factors. Based on the share price response at the time of the follow-on offering along with the share price response at the time of lockup expiration, the cumulative effects for IPOs complemented by follow-on offerings are about 6.96% weaker than for IPOs not complemented by follow-on offerings. Overall, follow-on offerings may benefit some insiders who can circumvent the lockup expiration date, at the expense of other investors.  相似文献

The Role of Lockups in Initial Public Offerings   总被引:4,自引:0,他引:4  
In a sample of 2,794 initial public offerings (IPOs), we testthree potential explanations for the existence of IPO lockups:lockups serve as (i) a signal of firm quality, (ii) a commitmentdevice to alleviate moral hazard problems, or (iii) a mechanismfor underwriters to extract additional compensation from theissuing firm. Our results support the commitment hypothesis.Insiders of firms that are associated with greater potentialfor moral hazard lockup their shares for a longer period oftime. Insiders of firms that have experienced larger excessreturns, are backed by venture capitalists, or go public withhigh-quality underwriters are more likely to be released fromthe lockup restrictions.  相似文献

The Expiration of IPO Share Lockups   总被引:9,自引:1,他引:9  
We examine 1,948 share lockup agreements that prevent insiders from selling their shares in the period immediately after the IPO (typically 180 days). While lockups are in effect, there is little selling by insiders. When lockups expire, we find a permanent 40 percent increase in average trading volume, and a statistically prominent three-day abnormal return of −1.5 percent. The abnormal return and volume are much larger when the firm is financed by venture capital, and we find that venture capitalists sell more aggressively than executives and other shareholders. We find limited support for several hypotheses that may explain the abnormal return, but no complete explanation.  相似文献

基于新兴市场的制度背景,本文以2009—2011在创业板上市的IPO公司为样本,综合动态分析了风险投资和风险投资联合差异对IPO前和锁定期结束当年的盈余管理的影响。研究发现,风险投资的参与影响了IPO公司的盈余管理,具体表现在风险投资的参与降低IPO前的盈余管理,以实现在锁定期结束当年的盈余反转,从而获得更高的股份减持收益。实证结果支持风险投资IPO行为的道德风险假设。在此基础上,研究还发现,在我国当期环境下,风险投资联合的差异增加了IPO前的盈余程度,却同时降低了锁定期结束当年的盈余管理程度,这说明风险投资联合并没有恶化风险投资的盈余管理,相反起到了抑制的作用。  相似文献

We investigate the determinants of venture capital (VC) exit behavior after the lockup expiry in initial public offerings (IPOs) by considering insights from prospect theory and behavioral finance for the first time. Hereby, the paper concentrates on the under-researched relationship between fund managers and the limited partners investing in these funds. The results from a proprietary dataset of 292 U.S. VC-backed IPOs from 1991 to 2008 imply that VC firm characteristics and fund dynamics have a significant influence on the exit extent after the lockup expiry and may not always be in line with limited partners' interests, hinting at the relevance of behavior grounded in prospect theory. In particular, first-time funds keep their shares longer after an IPO, whereas funds satisfied with current fund performance cash out soon after the end of the lockup period.  相似文献

本文以截至2011年6月30日在我国创业板上市的236家公司作为研究对象,研究风险投资对创业板IPO折价的影响。研究发现:(1)有风险投资参与的企业IPO折价显著高于无风险投资参与的企业,支持声誉效应假说,即风险投资机构以IPO折价来提早退出投资项目,以此来建立自己的声誉,从而吸引更多的资金流入;(2)在对有风投参股的投资公司做进一步分析后发现一一随着风投参与度的增大,IPO调整折价率并未出现明显的提升,创业板企业IPO时风险投资机构的数量、风险投资机构持股比例与调整折价率关系不显著。  相似文献
