Initial public offerings (IPOs) have been a prominent focus of academic and popular press attention, especially in recent years. Much of this attention can be attributed to the increase in IPO activity as a function of the “dot com” phenomenon. Of particular interest to both academics and practitioners is IPO underpricing. Review of existing research suggests little consensus regarding those factors associated with underpricing. We provide a meta-analysis of published studies. Our findings reveal a number of significant relationships, many of which are opposite that predicted by signaling theory. Implications of these findings for practice and future research are discussed.
