Therefore, the research about improving Securities Analyst forecast accuracy becomes very important in practice. This study was doing this job in order to find the antecedents of forecast accuracy, which has a very important practical significance for the securities market efficiency.

Conclusions were as follows: Securities analyst profit forecast error was divided into three states as “high reliability”, “accuracy”, and “occur significant prediction error”. We found that the proportion of the sample size of the first two states contribute nearly 60%, indicating a relatively high forecast accuracy for listed companies on GEM by securities analyst.
