Abstract

We study the aftermarket for 72 initial public offerings (IPOs) using comprehensive trade and quote-change data from every market maker for the first three days of trading. Underwriters quote higher bid prices than other market makers for issues that commence trading at or below the offer price. Underwriters repurchase large quantities of stock in the aftermarket without risk by overselling the issue by the amount of the overallotment option. If the IPO is hot, the overallotment option is exercised. If not, the short position is covered with aftermarket selling. We discuss several reasons for underwriter support. © 1994.
