Quantitative Models and Construction Methods 1. Model Name: Multi-Dimensional Timing Model - Model Construction Idea: Combines macro, micro, and meso signals with derivatives-based signals to form a four-dimensional non-linear timing model[24][25] - Model Construction Process: 1. Divide the A-share market into 9 states based on macro, meso, and micro signals, each corresponding to long/short signals[25] 2. Add derivatives signals derived from the basis of stock index futures to form a composite four-dimensional timing model[24] 3. Current macro environment prediction value is declining, meso-level prosperity is fluctuating at low levels, corresponding to state 4-2 in the three-dimensional model[25] 4. The latest derivative signal based on CSI 500 futures basis is 0.25 (long), resulting in a final composite signal of slightly increasing positions (0.25)[25] 2. Model Name: Industry Rotation Strategy 2.0 - Model Construction Idea: Constructs economic quadrants using credit and corporate earnings, and develops multi-dimensional industry style factors for rotation strategies[67] - Model Construction Process: 1. Define four economic quadrants: [Earnings Up, Credit Up], [Earnings Up, Credit Down], [Earnings Down, Credit Up], [Earnings Down, Credit Down][67] 2. Develop multi-dimensional industry style factors, including expected prosperity, exceeding expected earnings, leader effect, valuation bubble, reversal factor, momentum factor, crowding, and inflation beta[67] 3. Test the effectiveness of each factor in the four quadrants and allocate high-expected-return industries accordingly[67] 3. Model Name: Genetic Programming-Based Index Enhancement Models - Model Construction Idea: Uses genetic programming to mine factors and construct enhanced index models for stock selection[77][81][85][90] - Model Construction Process: - CSI 300 Index Enhancement: 1. Stock pool: CSI 300 constituents 2. Training set: 2016-01-01 to 2020-12-31 3. Factors: 102 factors derived from genetic programming (2000 initial populations, 5 generations, 7 rounds)[77] 4. Strategy: Weekly rebalance, selecting top 10% stocks in each industry based on model scores, with a transaction cost of 0.3%[77] - CSI 500 Index Enhancement: 1. Stock pool: CSI 500 constituents 2. Training set: 2016-01-01 to 2020-12-31 3. Factors: 189 factors derived from genetic programming (2000 initial populations, 5 generations, 8 rounds)[81] 4. Strategy: Weekly rebalance, selecting top 10% stocks in each industry based on model scores, with a transaction cost of 0.3%[81] - CSI 1000 Index Enhancement: 1. Stock pool: CSI 1000 constituents 2. Training set: 2016-01-01 to 2020-12-31 3. Factors: 564 factors derived from genetic programming (2000 initial populations, 5 generations, 4 rounds)[85] 4. Strategy: Weekly rebalance, selecting top 10% stocks in each industry based on model scores, with a transaction cost of 0.3%[85] - CSI All-Share Index Enhancement: 1. Stock pool: CSI All-Share constituents 2. Training set: 2016-01-01 to 2020-12-31 3. Factors: 709 factors derived from genetic programming (2000 initial populations, 5 generations, 10 rounds)[90] 4. Strategy: Weekly rebalance, selecting top 10% stocks in each industry based on model scores, with a transaction cost of 0.3%[90] --- Model Backtest Results 1. Multi-Dimensional Timing Model - CSI 500 Futures Signal: Weekly signal maintained at 0.4 to 1, triggering long signals on January 13, 14, and 17, 2025[41] - CSI 300 Futures Signal: Weekly signal maintained at -0.6 to -1, indicating short signals[41] 2. Industry Rotation Strategy 2.0 - Annualized Excess Return: - No exclusion version: 12.39%[69][74] - Double exclusion version: 12.65%[69][75] - Information Ratio (IR): - No exclusion version: 1.06[74] - Double exclusion version: 1.08[75] 3. Genetic Programming-Based Index Enhancement Models - CSI 300 Index: - Annualized Excess Return: 19.59%[78] - IR: 1.95[79] - Sharpe Ratio: 1.02[79] - CSI 500 Index: - Annualized Excess Return: 12.97%[82] - IR: 1.26[84] - Sharpe Ratio: 0.74[84] - CSI 1000 Index: - Annualized Excess Return: 19.60%[86] - IR: 1.90[87] - Sharpe Ratio: 0.82[87] - CSI All-Share Index: - Annualized Excess Return: 25.25%[92] - IR: 4.85[94] - Sharpe Ratio: 1.21[94] --- Quantitative Factors and Construction Methods 1. Factor Name: Industry Rotation Factors - Construction Idea: Develop multi-dimensional factors to capture industry rotation opportunities[67] - Construction Process: Includes factors such as expected prosperity, exceeding expected earnings, leader effect, valuation bubble, reversal factor, momentum factor, crowding, and inflation beta[67] 2. Factor Name: Barra Style Factors - Construction Idea: Evaluate market performance using 9 primary and 20 secondary style factors[43] - Construction Process: Factors include size, volatility, liquidity, momentum, quality, value, growth, analyst expectations, and dividends[43] --- Factor Backtest Results 1.
