Also, we test the information leakage (Tipping) before the public release of analysts reports. The major findings are as follows. First, we find that analyst reports have price informativeness. However, the relation between the analysts coverage and the price informativeness is significantly negative. Second, we find that the price informativeness of underwriter analysts is less than unaffiliated analysts due to conflicts of interest. Finally, we find that individual, domestic institutional and foreign institutional investorsabnormal tradings on release date are significantly large for both underwriter and unaffiliated analysts. However, all investorsabnormal tradings before release date arises only in the case of unaffiliated analysts reports. Especially, domestic institutional investors response to not only the release date of analysts reports but before public release. Therefore, we can not identify direct evidence of the tipping. In conclusion, we find that financial analysts in IPOs play a key role as information intermediaries rather than information producers. Furthermore, we identify that the informativeness of underwriter analysts are less than unaffiliated analysts due to conflicts of interest.
