Risk-Adjusting the Returns to Venture Capital
Performance evaluation of venture-capital (VC) payoffs is challenging because payoffs are infrequent, skewed, realized over endogenously varying time horizons, and cross- sectionally dependent. The authors of this study show that standard stochastic discount factor (SDF) methods can be adapted to handle these issues. The authors’ approach generalizes the Public Market Equivalent (PME) measure commonly used in the private-equity literature.
The authors find that the abnormal returns from both VC funds and VC start-up investments are robust to relaxing the strong distributional assumptions and implicit SDF restrictions from the prior literature: VC start-up investments earn substantial positive abnormal returns, and VC fund abnormal returns are close to zero.
The authors further show that the systematic component of start-up company and VC fund payoffs resembles the negatively skewed payoffs from selling index put options, which contrasts with the call option-like positive skewness of the idiosyncratic payoffs. Motivated by this finding, The authors explore an SDF that includes index put option returns.
This results in negative abnormal returns to VC funds, while the abnormal returns to start-up investments remain large and positive.
