Venture capital exit after venture IPO
研究了风险投资公司在创业公司IPO后为何继续持股而非退出，发现行业不确定性和正面私有信息会共同增加持股期权的价值，从而延迟退出。
Abstract Research Summary Venture 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 Summary When 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.
