Abstract

This paper proposes a new measure of ex ante equity premium, IPOFDR, which is the average difference between the offer price and the first-trading-day close price of IPO shares. The relation reflects the stylized fact that IPO issuers only partially incorporate market information during bookbuilding. I test the idea in three ways using U.S. data over the 1960 to 2006 period. First, there is a positive relation between IPOFDR and future market returns, and the relation is statistically significant in both in-sample and out-of-sample tests. Second, the unanticipated change in IPOFDR performs just as well as HML in explaining the cross-section of stock returns. Third, IPOFDR forecasts stock returns mainly because of its relation with stock market variance and average idiosyncratic variance, which are arguably measures of stock market risk.
