Quantitative Models and Construction - **Model Name**: Diffusion Index Model **Construction Idea**: The model monitors the future diffusion index's critical points to predict market changes[39][40] **Construction Process**: The diffusion index is calculated based on the relative price changes of constituent stocks over a specific time window. The horizontal axis represents the future price change percentage (from +10% to -10%), while the vertical axis represents the review period length (from 20 days to 10 days). For example, at a horizontal axis value of 0.95 and a vertical axis value of 15 days, the diffusion index is 0.42, indicating that if all constituent stocks drop by 5% after 5 days, the diffusion index value will be 0.42[39][41] **Evaluation**: The model is effective in identifying potential turning points in the market[40] - **Model Name**: First Threshold Method (Left-Side Trading) **Construction Idea**: This method triggers a buy signal when the diffusion index reaches a predefined threshold[43] **Construction Process**: The first threshold method triggered a buy signal on September 23, 2025, when the diffusion index reached 0.0575[43] **Evaluation**: The method is suitable for early-stage market entry[43] - **Model Name**: Delayed Threshold Method (Right-Side Trading) **Construction Idea**: This method provides a buy signal after the diffusion index stabilizes above the threshold[46] **Construction Process**: The delayed threshold method triggered a buy signal on September 25, 2025, when the diffusion index reached 0.1825[46] **Evaluation**: The method is more conservative and reduces false signals compared to the first threshold method[46] - **Model Name**: Dual Moving Average Method (Adaptive Trading) **Construction Idea**: This method uses two moving averages to generate trading signals based on their crossover[47] **Construction Process**: The dual moving average method provided a buy signal on October 13, 2025, at the market close[47] **Evaluation**: The method adapts to market trends and is effective in capturing medium-term signals[47] Model Backtesting Results - **Diffusion Index Model**: Current diffusion index value is 0.67, indicating a medium-high level. If the market rises by 4% next week, it will trigger the risk threshold[39][40] - **First Threshold Method**: Triggered buy signal at diffusion index value of 0.0575[43] - **Delayed Threshold Method**: Triggered buy signal at diffusion index value of 0.1825[46] - **Dual Moving Average Method**: Triggered buy signal on October 13, 2025[47] Quantitative Factors and Construction - **Factor Name**: Non-Liquidity Factor **Construction Idea**: Measures the illiquidity of stocks to predict their future performance[5][33] **Construction Process**: The rank IC for this factor is calculated weekly.
