Description

In this paper we study the returns on a set of different strategies, which are based on the sign and magnitude of the pre-earnings announcement return for a group of US stocks and for some international markets which provides an additional measure of robustness. We also propose a new methodology for the evaluation of abnormal returns. Evidence is found that stocks with negative abnormal returns on the days prior to the earnings announcement have a subsequent higher return on the days following the announcement. A trading strategy based on these findings is then reproduced and its results are analyzed.
