Quantitative Models and Construction Methods 1. Model Name: Diffusion Index Model - **Model Construction Idea**: The model is used to monitor the critical points of future diffusion index changes, providing insights into potential market turning points[34][35] - **Model Construction Process**: The diffusion index is calculated based on the relative price changes of constituent stocks over a specific time window. For example, if all constituent stocks drop by 5% after 5 days, the diffusion index value is 0.33. The current diffusion index value is 0.82, indicating a relatively uniform distribution[34][35] - **Model Evaluation**: The model provides a systematic way to observe market heat and potential upward space, though it is sensitive to the dynamic updates of constituent stocks[34][35] 2. Model Name: First Threshold Method (Left-Side Trading) - **Model Construction Idea**: This method triggers a sell signal when the diffusion index reaches a predefined threshold[39] - **Model Construction Process**: The first threshold method triggered a sell signal on May 8, 2025, when the diffusion index closed at 0.9850[39] 3. Model Name: Delayed Threshold Method (Right-Side Trading) - **Model Construction Idea**: Similar to the first threshold method but with a delayed signal to confirm the trend[41][43] - **Model Construction Process**: The delayed threshold method triggered a sell signal on May 15, 2025, when the diffusion index closed at 0.8975[43] 4. Model Name: Dual Moving Average Method (Adaptive Trading) - **Model Construction Idea**: This method uses two moving averages to adaptively identify trading signals[44] - **Model Construction Process**: The dual moving average method issued a sell signal again on August 4, 2025[44] --- Model Backtesting Results 1. Diffusion Index Model - Current diffusion index value: 0.82[34][35] 2. First Threshold Method - Triggered sell signal at diffusion index value: 0.9850[39] 3.
