When managers provide earnings guidance, analysts normally respond within a short time frame with their own earnings forecasts. Within this setting, I investigate whether financial analysts use publicly available information to adjust for predictable error in management guidance and, if so, the explanation for such inefficiency. I provide evidence that analysts do not fully adjust for predictable guidance error when revising forecasts. The analyst inefficiency is attributed to analysts' attempts to advance relationship with the managers, analysts' compensation not tie to forecast accuracy, and their forecasting ability. Finally, the stock market acts as if it does not fully realize that analysts respond inefficiently to the guidance, introducing mispricing. This mispricing is not fully corrected upon earnings announcement.
