Quantitative Models and Construction Methods 1. Model Name: Continuous Hedging Strategy - **Model Construction Idea**: The strategy is based on the convergence of basis factors in stock index futures and optimizes hedging through continuous adjustments[47] - **Model Construction Process**: - **Backtesting Period**: From July 22, 2022, to May 23, 2025[48] - **Spot Side**: Hold the total return index of the corresponding underlying index[48] - **Futures Side**: Use 70% of the funds for the spot side and short the futures side with the same nominal principal, occupying the remaining 30% of the funds. After each rebalancing, recalculate the quantities of the spot and futures sides based on the product's net value[48] - **Rebalancing Rules**: Continuously hold quarterly/monthly contracts until the remaining time to maturity is less than 2 days. Close the position at the closing price on that day and simultaneously short the next quarterly/monthly contract at the closing price[48] - **Assumptions**: Equal allocation of principal between the spot and futures sides, excluding transaction fees, impact costs, and the indivisibility of futures contracts[48] 2. Model Name: Minimum Discount Hedging Strategy - **Model Construction Idea**: This strategy selects futures contracts with the smallest annualized basis discount for hedging, aiming to optimize returns[49] - **Model Construction Process**: - **Backtesting Period**: From July 22, 2022, to May 23, 2025[49] - **Spot Side**: Hold the total return index of the corresponding underlying index[49] - **Futures Side**: Use 70% of the funds for the spot side and short the futures side with the same nominal principal, occupying the remaining 30% of the funds. After each rebalancing, recalculate the quantities of the spot and futures sides based on the product's net value[49] - **Rebalancing Rules**: Calculate the annualized basis for all tradable futures contracts on the day of rebalancing and select the contract with the smallest discount for opening a position. Hold the same contract for 8 trading days or until the remaining time to maturity is less than 2 days before selecting a new contract. Even if the result is to hold the original contract, it must still be held for 8 trading days[49] - **Assumptions**: Equal allocation of principal between the spot and futures sides, excluding transaction fees, impact costs, and the indivisibility of futures contracts[49] --- Model Backtesting Results 1.
