Abstract:Most initial public offerings (IPOs) feature "lockup" agreements, which bar insiders from selling the stock for a set period following the IPO, usually 180 days. We examine stock price behavior in the period surrounding lockup expiration for a sample of 2,529 firms from 1988 to 1997. We find that lockup expirations are, on average, associated with significant and negative abnormal returns, but the losses are concentrated in firms with venture capital backing. For the venture-capital-backed group, the largest l… Show more
“…This result is somewhat surprising in the light of the results from other country studies. Bradley et al (2001) find that VC-backed US IPOs are associated with significantly more negative abnormal returns at the lock-in expiry. Similar results are found by Field and Hanka (2001), Brav and Gompers (2003) and Brau et al (2004) for the US; Espenlaub et al (2003) for the UK; Bessler and Kurth (2003) for Germany; and Bertoni et al (2002) for Italy.…”

“…There is very high abnormal trading volume during the first ten days after the lock-in expiry. It is also clear that the increase in trading volume at lock-in expiry is substantially larger for venture-capital backed firms, as documented by Bradley et al (2001) and Field and Hanka (2001).…”

This paper unveils the diversity in lock-in agreements of firms listed on the Nouveau Marché stock exchange in France. We give the main economic reasons why shareholders adopt lock-in agreements that are more stringent than legally required. We relate the abnormal returns and the abnormal volume at the expiry dates of the different types of lock-in contracts to the degree of underpricing, venture-capitalist reputation and underwriter reputation. Abnormal returns and trading volume increase at the lock-in expiry; this is especially pronounced at the expiry dates of insider lock-in contracts as insiders are legally required to be locked-in. We do not find significant abnormal returns at the expiries of VC contracts, even though trading volume increases at their lock-in expiry. There is also no evidence of a positive (negative) relation between abnormal returns (abnormal volume) and more stringent lock-in contracts. Lock-in contracts and the degree of underpricing are complementary signalling devices.JEL codes: G30, G34, G38

“…Ofek Xiong (2006) further shows that an increase in floating assets, such as at the end of an IPO lockup, can cause price depreciation when pessimistic investors are able to sell. IPO evidence (Field and Hanka 2001, Bradley, Jordan, Yi, and Roten 2001, Brav and Gompers 2003 documents an average −1% to −2% cumulative abnormal return and 40% abnormal volume during short windows upon the IPO unlock-up.…”

“…Previous literature (Field and Hanka 2001, Bradley, Jordan, Yi, and Roten 2001, Brav and Gompers 2003 documents negative abnormal returns and positive abnormal volume associated with IPOs upon the lockup expiration. We add to this research by showing that these negative price reactions are much stronger among firms with high idiosyncratic volatility, where the value-weighted negative price responses are one to three times larger.…”

“…During the IPO lock-up period, insiders and other pre-IPO stockholders typically cannot sell their shares for six months (Bradley, Jordan, Yi, and Roten 2001). The inability to sell owned shares is deemed the most stringent short-sale constraint (Ofek and Richardson 2003).…”
Using event studies, we show that short-sale constraints play an important role in the negative relation between idiosyncratic volatility and stock returns. We explore three exogenous events that change short-sale constraints: the IPO lockup period expiration, option introduction, and the recent short-selling ban on financial stocks. Following mitigation of short-sale constraints from the first two events, high idiosyncratic volatility stocks underperform low volatility stocks in the short and long run, and are associated with higher abnormal trading volume. Additionally, highly volatile financial firms experience greater price increases upon the short-sale ban enforcement and greater price drops upon the ban expiration.
Research SummaryVenture capital firms (VCs) sometimes continue to hold significant equity stakes in entrepreneurial ventures after venture IPO. The information economics view suggests that retaining equity signals VC commitment and venture quality. This study conceptualizes retaining equity as holding an exchange option, the option to exchange VCs' own valuation of IPO ventures for the market's valuation. Holding this option allows VCs to benefit from the ventures' upside potential. Since exit amounts to giving up the option, the option value represents an opportunity cost of exit. VCs may delay exit if this option is sufficiently valuable. The study examines two key conditions that interact to increase the value of this option: uncertainty and positive private information. This study contributes to research on VC exit and real options.Managerial SummaryWhen do VCs retain equity rather than exit after venture IPO? Researchers have addressed the impact of signaling, cash constraints, human capital constraints, blockholding, VC fund performance, portfolio diversification and institutional features. We identify a previously unrecognized driver: to retain the opportunity to benefit from an IPO venture's upside potential that is yet to be fully recognized or realized. We submit that VCs' incentive to retain equity increases with uncertainty in the venture's industry, and VCs' positive private information as indicated by venture patent applications and positive market surprises in the venture's industry. We find largely supportive evidence for the positive joint effect of uncertainty and private information on the decision to retain equity within the first year or even two years after IPO lockup expiration.
