Unexpected management forecasts and future stock returns

Abstract

AbstractThis study investigates the effect of managerial discretion regarding initial earnings forecasts on future stock returns for Japanese firms. We estimate the unexpected portion of initial management earnings forecasts (“unexpected forecasts”) based on the findings of fundamental analysis research and define it as a proxy for forecast management. Using this measure, we find that firms with higher unexpected forecasts are related to negative abnormal returns over the subsequent 12 months. By contrast, the expected portion of earnings forecasts is not related to future abnormal returns. These results suggest that the market tends to appropriately price the credible portion of management forecasts, while overpricing the less credible portion. Further analysis reveals that the relationship between unexpected forecasts and future returns is (1) distinct from accruals anomaly, notably (2) in the 6‐month return window, (3) in the first half of the sample period (especially in 2005 and 2006), (4) in extreme unexpected forecast news and (5) in a poor information environment. This study extends the literature by focusing on a more desirable research setting in Japan, compared to other studies, to explore management forecasts and present new implications for the market pricing of management earnings forecasts.
