Choosing a suitable clustering method is crucial in using time series clustering in stock index futures hedging. This study aims to investigate and improve the application performance of time series clustering in the financial data analysis field from a new perspective. We propose a model of stock index futures hedging based on label propagation time series clustering. In the model, a network space of spot stock was built using dynamic time warping as similarity measure. Each stock in the network was treated as a node, which would be divided into different clusters using label propagation, and finally, the stock data was clustered successfully. An optimization model for minimizing tracking error was constructed to obtain the optimal weight of each stock in the spot portfolio. Finally, we obtained the optimal spot portfolio. The tracking errors of the portfolio of the proposed method and that of the traditional clustering method were compared by tracking the index in the experiment. The proposed method showed the ability to improve tracking accuracy, providing a new way to enrich the investment and management of financial market.
