An Assessment Of Event Study Methodologies Using Daily Stock Returns

Abstract

This paper examines Multinational Stock Price reactions to foreign currency translation, using three alternative residual methodologies. The results reveal that when a crude measure such as Mean Adjusted Return, which makes not explicit risk adjustments is used, the null hypothesis of zero abnormal return is rejected in three out of six events. However, market and risk adjusted residual returns reveal that the null hypothesis of zero abnormal return cannot be rejected.
