Quantitative Models and Construction Methods 1. Model Name: Diffusion Index Model - **Model Construction Idea**: The diffusion index is used to monitor the critical points of market trend changes, helping to identify potential buy or sell signals based on the distribution of stock price movements within the micro-cap index components [5][35]. - **Model Construction Process**: The diffusion index is calculated by analyzing the relative price changes of micro-cap index components over a specific time window. For example, if all stocks in the index drop by 5% after 5 days, the diffusion index value is 0.37. The formula and methodology involve tracking the relative price changes over different time horizons (e.g., 10 to 20 trading days) and calculating the index value based on the distribution of these changes [35][37]. - **Model Evaluation**: The diffusion index remains in a high volatility range, indicating that the market is neither "too expensive" nor "too cheap." It is sensitive to large price movements, which can trigger buy or sell signals [5][36]. 2. Model Name: Threshold Methods (First and Delayed) - **Model Construction Idea**: These methods aim to provide trading signals (e.g., open or close positions) based on predefined threshold values of the diffusion index [5][39][43]. - **Model Construction Process**: - **First Threshold Method**: Triggered when the diffusion index crosses a specific threshold. For instance, on May 8, 2025, the index value of 0.9850 triggered a sell signal [39]. - **Delayed Threshold Method**: Similar to the first method but with a delayed response. For example, on May 15, 2025, the index value of 0.8975 triggered a sell signal [43]. - **Model Evaluation**: These methods are effective for identifying turning points in the market but may require careful calibration to avoid false signals [5][43]. 3. Model Name: Dual Moving Average Method - **Model Construction Idea**: This method adapts to market trends by using two moving averages to generate trading signals [5][44]. - **Model Construction Process**: - Signals are generated when the short-term moving average crosses the long-term moving average. For example, on April 30, 2025, the method provided a buy signal [44]. - **Model Evaluation**: The dual moving average method is adaptive and suitable for trending markets but may lag in highly volatile conditions [5][44]. --- Model Backtesting Results 1. Diffusion Index Model - Current value: 0.79 (as of June 6, 2025) [35][36] 2.
