Quantitative Models and Construction Methods 1. Model Name: Continuous Hedging Strategy - **Model Construction Idea**: This strategy is based on the analysis of basis convergence factors and optimization strategies, as detailed in the "Cinda Financial Engineering Derivatives Research Report Series III"[44] - **Model Construction Process**: - **Backtesting Period**: From July 22, 2022, to August 15, 2025[45] - **Spot Side**: Hold the total return index of the corresponding underlying index[45] - **Futures Side**: Use 70% of the funds for the spot side and allocate the same nominal principal amount to short futures contracts of CSI 500, CSI 300, SSE 50, and CSI 1000 indices, occupying the remaining 30% of the funds[45] - **Rebalancing Rules**: Continuously hold quarterly/monthly contracts until the remaining time to maturity is less than 2 days, then close the position at the closing price and simultaneously short the next quarterly/monthly contract at the closing price[45] - **Assumptions**: Equal allocation of principal between spot and futures sides, excluding transaction fees, impact costs, and the indivisibility of futures contracts[45] 2. Model Name: Minimum Basis Strategy - **Model Construction Idea**: This strategy selects contracts with the smallest annualized basis discount to optimize hedging performance[46] - **Model Construction Process**: - **Backtesting Period**: From July 22, 2022, to August 15, 2025[46] - **Spot Side**: Hold the total return index of the corresponding underlying index[46] - **Futures Side**: Use 70% of the funds for the spot side and allocate the same nominal principal amount to short futures contracts of CSI 500, CSI 300, SSE 50, and CSI 1000 indices, occupying the remaining 30% of the funds[46] - **Rebalancing Rules**: Calculate the annualized basis for all tradable futures contracts on the day of rebalancing and select the contract with the smallest basis discount for opening positions. Hold the same contract for 8 trading days or until the remaining time to maturity is less than 8 days before selecting a new contract[46] - **Assumptions**: Equal allocation of principal between spot and futures sides, excluding transaction fees, impact costs, and the indivisibility of futures contracts[46] --- Model Backtesting Results 1.
