Based on a textual analysis of initial public offering (IPO) prospectuses, we obtain a number of important findings regarding the relation between the conservatism in prospectuses, IPO pricing, and subsequent operating and stock return performance. First, prospectus conservatism is positively related to underpricing, with the relation more pronounced for technology than nontechnology firms. Second, for nontechnology IPOs, prospectus conservatism is able to predict the firm’s post-IPO operating performance. Specifically, we find that conservatism is inversely related to the firm’s operating performance for the 3 years following the IPO. However, this predictability is limited to nontechnology IPOs. Finally, we find some evidence that for nontechnology IPOs conservatism is inversely related to the firm’s post-IPO abnormal stock return. We conclude that the conservatism contained in an IPO’s prospectus contains useful information about pricing and subsequent operating and stock return performance. Moreover, prospectus conservatism for nontechnology IPOs deserves more attention from investors.

This study examines the role that chief executive officer (CEO) overconfidence plays in an explanation of international mergers and acquisitions during the period 2000–2006. Using a sample of CEOs of Fortune Global 500 firms over our sample period, we find that CEO overconfidence is related to a number of critical aspects of international merger activity. Overconfidence helps to explain the number of offers made by a CEO, the frequencies of nondiversifying and diversifying acquisitions, and the use of cash to finance a merger deal. Although overconfidence is an international phenomenon, it is most extensively observed in individuals heading firms headquartered in Christian countries that encourage individualism while de-emphasizing long-term orientation in their national cultures.
