Research on Price Prediction of Stock Price Index Based on Combination Method with Introduction of Options Market Information by Yi Hu, Xin Sui, Qi Zhang, Wei Zhang

“…Prior to optimization, predictions incorporating in-the-money call options with maximum trading volume yield the optimal performance based on the MSE metric. (3) Under the logical framework of the combination method, the prediction effect for the CSI 300 stock index price is gradually improved after introducing the decomposition–clustering method, the error adjustment method, and the price-weighted integration method, which shows that it is appropriate to use the combination method to optimize the price prediction. …”
