In this paper the compound forecasting method is discussed. The compound forecasting method is one of the hotspots in the current predication. Firstly, the compound forecasting method is introduced and various existing compound forecasting methods are discussed. Secondly, the Artificial Neural Network( ANN ) is brought in compound prediction research and a nonlinear compound prediction model based on ANN is presented. Finally, in order to avoid irregular weight, a new method is presented which uses principal component analyses to increase the availability of compound forecasting information. Higher forecasting precision is achieved in practice.
