论文摘要:

 

This paper offers a joint test of two plausible explanations (difference-in-opinion vs. analyst self-censoring) for why stocks with higher dispersion in analysts’ earnings forecasts earn lower subsequent returns (“dispersion effect”). We recognize the possibility that institutional ownership can be endogenous, and the bias this would cause in the tests of the dispersion effect. We address this concern by exploiting the exogenous variations in institutional ownership generated by the annual reconstitution of the Russell 3000 index. In contrast to the evidence that firms with higher institutional ownership have weaker dispersion effect found in the general sample, we find the exactly opposite in the Russell sample. Furthermore, we find parallel results when we replace stock returns by analyst forecast bias. These results strongly suggest that analyst self-censoring rather than the more popular difference-in-opinion story is the more plausible explanation for the dispersion effect, at least in a sample where endogeneity bias of institutional ownership is minimized.
