Purpose Conventional wisdom says that the price reduction stocks experience at expiration of the initial public offering (IPO) lockup period is due to relaxation of selling constraints. Findings from more recent literature question this explanation. The purpose of this paper is to examine a different cause for this price drop, IPO overvaluation. Design/methodology/approach Using the IPO overvaluation measures of Purnanandam and Swaminathan (2004), the authors examine IPO lockup period stock return differences between stocks in the highest and lowest overvaluation quintiles. Findings The authors show that the IPO lockup period price reduction is strongly related to overvaluation. Zero-investment portfolios long in the lowest overvaluation quintile and short in the highest overvaluation quintile of IPO firms have positive significant returns. Practical implications IPO investors can use the technique to identify firms likely to underperform in the IPO lockup period, potentially avoiding bad investments. Originality/value This is the first study to link IPO lockup period stock returns to IPO overvaluation, providing evidence on the impact of both overvaluation and short-selling constraints on stock returns in the IPO lockup period.

We use the initial public offering (IPO) setting to provide evidence that the combination of valuation uncertainty and short-sales constraints generates significant equity market mispricing. The IPOs that we predict to be most susceptible to overpricing in the immediate aftermarket have first-day returns of +47% and lockup expiration returns of [Formula: see text]9%. Our detailed analysis of securities lending market data confirms that these IPOs experience severe short-sales constraints that peak around the lockup expiration. Our paper both explains the anomalous pricing of IPOs and highlights the importance of valuation uncertainty and short-sales constraints in explaining equity mispricing. This paper was accepted by Brian Bushee, accounting.

ABSTRACT: This study explores how firms' ownership structures affect their earnings quality and long-term performance. Focusing on a unique sample of private firms for which there is financial data available in the years before and after their initial public offering (IPO), I differentiate between those that have private equity sponsorship (PE-backed firms) and those that do not (non-PE-backed firms). The findings indicate that PE-backed firms generally have higher earnings quality than those that do not have PE sponsorship, engage less in earnings management, and report more conservatively both before and after the IPO. Further, PE-backed firms that are majority-owned by PE sponsors exhibit superior long-term stock price performance after they go public. These results stem from the professional ownership, tighter monitoring, and reputational considerations exhibited by PE sponsors.

This study examines the relationship between initial public offering (IPO) managers' earnings management behavior during lockup (measured with discretionary accruals, DAs) and operating performance following lockup expiration (measured with operating return on assets, OPROAs). Based on a U.S. IPO sample, the results indicate that DAs during lockup are significantly higher than after lockup expiration. In addition, the reversal effect of DAs results in a negative association of DAs in lockup with post-lockup OPROAs. This negative relation is primarily concentrated in small-sized, non-venture backed, high-tech, and hot-market issued IPOs and is consistent with prior findings that such IPO firms have poorer post-issue performance. The overall evidence supports the role of managerial earnings management behavior during lockup in explaining post-IPO operating underperformance.

We examine the effects of venture capitalist involvement and equity incentives for all employees on the performance of initial public offering firms. Data was collected from 402 IPO firms, representing 242 non-VC backed and 160 VC backed firms. Results indicate venture capitalists positively influence the likelihood the portfolio firm will offer equity incentives to all employees. Consistent with the agency theory argument that monitoring and incentives can behave as complements to one another, the results suggest venture capitalist backing and incentive stock options for all employees operate in concert to have a positive effect on stock price performance three years after the initial public offering.

Managers’ commitment and dedication crucially affect the sustainable growth of firms. When private companies first offer their shares to the public in an initial public offering (IPO), an IPO lockup is one way of revealing managers’ commitments. IPO lockups are agreements that promise not to sell the shares retained by pre-IPO shareholders for a specified period in the market after the IPO. This paper investigates the impact of corporate governance mechanisms on the length of the lockup period. The paper’s sample consists of IPO firms that have gone public in Korea’s KOSDAQ market, which is a listing venue for small and venture companies. The major findings of this paper are as follows: first, the length of the lockup period increases with the number of outside directors and, second, IPO firms with audit committees have longer lockup periods than those without them. These results indicate that managers of firms with greater board independence choose a longer lockup period when going public. This paper also finds that the lockup period is positively related to the presence of venture capitalists serving as directors of IPO firms, which suggests that venture capital directors may ensure that managers have longer lockups. Overall, these findings suggest that, when small and venture companies go public, managers may use the IPO lockup as a commitment device that complements corporate governance mechanisms in reducing investor concern about the moral hazard problem of managers.
