The superiority and disciplining role of independent analysts

We show that although forecasts of independent analysts are less accurate ex post, they yield forecast errors that are more strongly associated with abnormal stock returns. This suggests that forecasts of independent analysts are superior to those of nonindependent analysts in representing ex ante market expectations. We also show that forecasts of nonindependent analysts become more accurate and less biased, and produce forecast errors more strongly associated with abnormal stock returns when independent analysts are following the same firms than when they are not. This suggests that the presence of independent analysts disciplines the behavior of nonindependent analysts.
