Abstract

Using a sample of 279 buyout backed firms, I examined the effect of lockup agreements on the firm’s stock returns. I found there to be a negative .8 percent cumulative abnormal return for the three-day period surrounding lockup expiration. Consistent with my hypothesis the CAR for the three-day period surrounding lockup expiration was less negative for buyout backed IPOs compared to venture capital backed IPOs. In addition, I found there to be an abnormal 24.24 percent increase in trading volume for the three days surrounding lockup expiration.
