Abstract

Abstract The purpose of this study is to apply a unit root test to examine the stationarity of corporate earnings per share (eps) series. We find evidence to support the stationarity of corporate eps data. Furthermore, outlier analysis is employed and supports the long-run stability of corporate earnings series.
