Based on the Golden State securities analysts rating report data, the investment value of the analysts recommendation is examined and the yield bias resulting from the rating deviation is calculated, so as to measure the accuracy of analysts recommendation. The results show that the securities analysts recommendation has certain investment value as well as a tendency towards optimism. The complex interest conflicts of securities analysts may cause the bias of rating report to some extent. The impact of analysts rating bias on the interests of investors is also discussed, which is a new angle of view on the issues about the relation between the interest conflicts of analysts and their recommendation and so on.
