MPRA Paper from University Library of Munich, Germany

Abstract: Previous research on the impact of currency risk on stock returns has failed to find a significant role for foreign exchange rates. This paper addresses several explanations of this finding with a unique dataset of U.S. firms that acquire targets in other countries. The dataset allows estimation of the impact of exchange rates using firm-specific bilateral exchange rates and a time period over which underlying exposure is known to significantly change. We also relate the change in exposure from before to after the acquisition to various characteristics of the acquirer, such as its presence in the target country prior to the deal and its hedging activities, and characteristics of the target, such as the exposure of the target prior to the deal. The results suggest that identifying a relevant exchange rate can be an important consideration in studying the impact of exchange rate risk on stock returns, but identifying financial hedging information is not. Further, foreign targets often provide operational hedging benefits to the U.S. acquirers, as exposure estimates are significantly affected by the acquisition.
