This paper examines stock price formation subsequent to management forecasts of quarterly earnings. In the post‐announcement period, we find a significant upward price drift for both good news forecasts and bad news forecasts. Combined with the asymmetry in the initial market response, the upward post‐guidance drift in stock prices is consistent with a reversal of an initial overreaction to managers’ bad news forecasts and a continuation of an initial underreaction to managers’ good news forecasts. This interpretation is supported by a negative (positive) relationship between the initial market response and the post‐guidance drift in the bad news (good news) group. The drift pattern is robust to issues arising from measurement. Trading strategies exploiting the post‐announcement drift suggest the existence of economically significant trading profits, net of estimated trading costs.
