The prognostics of diversifying acquisitions

Abstract

Abstract The paper offers a possible explanation for the discrepancy between the observed increase in the number of diversified firms in the U.S. and the evidence from finance studies which at best offers only weak support for value creation in diversifying acquisitions. It is argued that the acquisition could be the culmination of a series of related strategic moves by the acquiring firm to enter a new industry, and therefore a significant fraction of the gains from synergy could have been anticipated by the capital market well ahead of the acquisition. Results from an event study of the stock market's reactions to the antecedents of the recent acquisition of Rolm Inc. by IBM lend support to this argument.
