We empirically investigate the association between institutional ownership and earnings forecasted by analysts. Consistent with this hypothesis, we find that firms with greater institutional ownership are more likely pressed to disclose and analysts’ forecasts tend to be more accurate. Subsample analysis conclude that the accuracy of forecast decline after implementation of Regulation Fair Disclosure (Reg. FD). In addition, we examine the relation between types of institutional investors and the quality of earnings forecasts. If the firm has more conservative and restricted institutional investors such as pension fund and brokerage firms, it may have more accurate analysts’ forecasts.
