Quantitative Models and Construction Methods 1. Model Name: Stock Index Futures Timing Model - Model Construction Idea: The model uses the basis of stock index futures to reflect market sentiment changes and constructs daily frequency timing signals based on this correlation[7] - Model Construction Process: - The model groups and tests the correlation trend between the basis of stock index futures and the index itself - Constructs daily frequency timing signals based on this correlation - As of October 17, 2025, the timing signal based on the basis of the CSI 500 stock index futures remained at 1[31] - Model Evaluation: The model effectively captures market sentiment changes and provides timely signals for trading decisions[7] 2. Model Name: Multi-Dimensional Timing Model - Model Construction Idea: The model integrates macro, micro, meso, and derivative signals to form a four-dimensional non-linear timing model[33] - Model Construction Process: - The A-share market is divided into nine states based on macro, micro, and meso signals, each corresponding to long and short signals to form a three-dimensional large cycle timing signal - On this basis, the derivative signal generated by the basis of stock index futures is superimposed to form a four-dimensional non-linear timing model - The latest composite multi-dimensional timing signal is long (1)[34] - Model Evaluation: The model provides a comprehensive view of market conditions by integrating multiple dimensions, enhancing the accuracy of timing signals[33] 3. Model Name: Style Enhancement Model - Model Construction Idea: The model enhances returns by adding enhancement factors to the multi-style strategy, suppressing single-style fluctuations, and achieving stable excess returns in different cycles[41] - Model Construction Process: - The model is based on the multi-style strategy and adds enhancement factors - It dynamically adjusts the weights of different styles to achieve stable excess returns - As of October 17, 2025, the low volatility enhancement strategy achieved an excess return of 6.05%[42] - Model Evaluation: The model effectively enhances returns while controlling risks, providing stable performance across different market cycles[41] Model Backtesting Results Stock Index Futures Timing Model - Absolute Return: Not specified - Excess Return: 4.33%[9] - Annualized Return: Not specified - Sharpe Ratio: Not specified Multi-Dimensional Timing Model - Absolute Return: Not specified - Excess Return: 4.33%[9] - Annualized Return: Not specified - Sharpe Ratio: Not specified Style Enhancement Model - Absolute Return: Not specified - Excess Return: 6.05%[8] - Annualized Return: Not specified - Sharpe Ratio: Not specified Quantitative Factors and Construction Methods 1. Factor Name: High-Frequency Factor - Factor Construction Idea: The factor captures market valuation and sentiment risks using high-frequency data[11] - Factor Construction Process: - The factor uses high-frequency data to measure market depth, spread, and price elasticity - Constructs indicators such as average depth, spread, and price elasticity to reflect market liquidity and sentiment - For example, the average depth is calculated as: $avg_{depth} = \frac{av1 + bv1}{2}$ where av1 and bv1 are the sell and buy volumes at the first level of the order book[98] - Factor Evaluation: The factor effectively captures market liquidity and sentiment changes, providing valuable insights for trading decisions[11] Factor Backtesting Results High-Frequency Factor - Absolute Return: Not specified - Excess Return: Not specified - Annualized Return: Not specified - Sharpe Ratio: Not specified Industry and ETF Rotation Strategy 1. Strategy Name: Industry Rotation Strategy - Strategy Construction Idea: The strategy uses quantitative fundamental drivers, quality low volatility style drivers, and distressed reversal industry discovery methods to construct an industry rotation strategy[76] - Strategy Construction Process: - Combines industry fundamental rotation, quality low volatility, and distressed reversal three-dimensional industry rotation strategies into an equal-weight portfolio - Selects industries from different dimensions to achieve factor and style complementarity, reducing the risk of a single strategy - As of October 17, 2025, the annualized excess return of the industry rotation strategy based on three-strategy integration was 10.59%, with a Sharpe ratio of 0.74[80] - Strategy Evaluation: The strategy effectively combines multiple dimensions to enhance returns while controlling risks, providing stable performance across different market cycles[76] Strategy Backtesting Results Industry Rotation Strategy - Absolute Return: Not specified - Excess Return: 14.75%[10] - Annualized Return: 10.59%[80] - Sharpe Ratio: 0.74[80]
