Quantitative Models and Construction 1. Model Name: Macro + Volume-Price Dual-Driver Large-Cap and Small-Cap Rotation Strategy - **Model Construction Idea**: This model integrates macroeconomic factors and micro-level volume-price factors to predict the rotation between large-cap and small-cap styles[6][7] - **Model Construction Process**: - The model uses multiple single-factor signals, including PMI seasonal average difference, social financing growth rate, monetary liquidity, US-China interest rate spread, macro adjustment momentum, and style crowding indicators[7] - Each factor is assigned a signal value: 1 for large-cap signals, -1 for small-cap signals, and 0 for no effective signal[7] - The comprehensive score is calculated by summing the signals of all factors. If the score > 0, the portfolio is fully allocated to the CSI 300 Index; if the score < 0, it is fully allocated to the CSI 1000 Index; if the score = 0, the portfolio is equally weighted between the two indices[7] - **Model Evaluation**: The model demonstrates a high backtest win rate of 82.22% as of Q1 2025, indicating strong predictive power[6] 2. Model Name: Macro + Volume-Price Dual-Driver Value-Growth Rotation Strategy - **Model Construction Idea**: This model integrates macroeconomic factors and micro-level volume-price factors to predict the rotation between value and growth styles[12][13] - **Model Construction Process**: - The model uses multiple single-factor signals, including PMI new orders seasonal average difference, PPI-CPI growth rate, 1-year government bond yield, 3-month US bond yield, macro adjustment momentum, style crowding indicators, and market sentiment[13] - Each factor is assigned a signal value: 1 for value signals, -1 for growth signals, and 0 for no effective signal[13] - The comprehensive score is calculated by summing the signals of all factors. If the score > 0, the portfolio is fully allocated to the CSI Value Index; if the score < 0, it is fully allocated to the CSI Growth Index; if the score = 0, the portfolio is equally weighted between the two indices[13] - **Model Evaluation**: The model demonstrates a backtest win rate of 77.78% as of Q1 2025, showcasing its effectiveness in predicting style rotations[12] 3. Model Name: Industry Rotation Model (Single-Factor Multi-Strategy and Composite Factor Strategy) - **Model Construction Idea**: This model evaluates industry rotation using factors from historical fundamentals, expected fundamentals, sentiment, volume-price technicals, and macroeconomics[18][19] - **Model Construction Process**: - Single-factor multi-strategy: Constructs portfolios based on individual factors and evaluates their performance[18] - Composite factor strategy: Combines multiple factors into a composite score to rank industries and construct portfolios[18] - Both strategies select the top 5 industries from the 30 first-level industries in the CITIC classification and construct equal-weighted long portfolios[18] - **Model Evaluation**: The single-factor multi-strategy outperformed the composite factor strategy in May 2025, with higher monthly absolute and excess returns[20] --- Backtest Results of Models 1.

Quantitative Models and Construction Methods - **Model Name**: Style Rotation Model **Model Construction Idea**: The model is built from micro-level stock factors, focusing on valuation, market capitalization, volatility, and momentum. It integrates a style timing and scoring system to construct a monthly frequency style rotation framework[1][6] **Model Construction Process**: 1. Start with 80 base micro-level factors selected based on the Dongwu multi-factor system[6] 2. Generate 640 micro-level features from these base factors[6] 3. Replace the absolute proportion division of style factors with commonly used indices as style stock pools to create new style returns as labels[6] 4. Use a rolling training random forest model to avoid overfitting risks, optimize feature selection, and derive style recommendations[6] 5. Construct a framework that transitions from style timing to style scoring and finally to actual investment decisions[6] **Model Evaluation**: The model effectively avoids overfitting risks and provides a comprehensive framework for style rotation[6] Model Backtesting Results - **Style Rotation Model**: - Annualized Return: 21.56% - Annualized Volatility: 24.17% - IR: 0.89 - Monthly Win Rate: 58.82% - Maximum Drawdown: 28.33%[7][8] - Excess Performance (Hedged Against Benchmark): - Annualized Return: 13.45% - Annualized Volatility: 11.47% - IR: 1.17 - Monthly Win Rate: 66.18% - Maximum Drawdown: 10.28%[7][8] Quantitative Factors and Construction Methods - **Factor Name**: Valuation, Market Capitalization, Volatility, Momentum **Factor Construction Idea**: These are foundational style factors used to construct the style rotation model. They are further refined into micro-level features and integrated into the model's scoring and timing system[1][6] **Factor Construction Process**: 1. Valuation: Derived from traditional valuation metrics such as P/E, P/B, and dividend yield[6] 2. Market Capitalization: Categorized into large-cap and small-cap stocks based on market size[6] 3. Volatility: Measured using historical price fluctuations[6] 4. Momentum: Calculated based on past price trends and returns[6] Factor Backtesting Results - **Factor Performance (2025, Multi-Factor Timing Results)**: - Valuation: -2.00% - Market Capitalization: 4.00% - Volatility: -6.00% - Momentum: -8.00%[10][17] - **Factor Performance (2025, Actual Factor Returns)**: - Valuation: 2.00% - Market Capitalization: 6.00% - Volatility: -4.00% - Momentum: -8.00%[10][11] Additional Notes - **Latest Style Timing Directions (May 2025)**: Value, Large-Cap, Reversal, Low Volatility[14] - **Latest Holding Index (May 2025)**: CSI Dividend Index[15]
