Quantitative Models and Construction 1. Model Name: Timing System Model - **Model Construction Idea**: This model uses the distance between the short-term moving average (20-day) and the long-term moving average (120-day) of the WIND All A Index to determine the market trend. If the short-term moving average is above the long-term moving average and the absolute distance exceeds 3%, the market is considered to be in an upward trend[2][10][16] - **Model Construction Process**: 1. Calculate the 20-day moving average (short-term) and the 120-day moving average (long-term) of the WIND All A Index 2. Compute the percentage difference between the two moving averages: $ \text{Distance} = \frac{\text{20-day MA} - \text{120-day MA}}{\text{120-day MA}} \times 100\% $ - 20-day MA: Short-term moving average - 120-day MA: Long-term moving average 3. If the distance is greater than 3% and the short-term moving average is above the long-term moving average, the market is in an upward trend[2][10][16] - **Model Evaluation**: The model effectively identifies upward market trends and provides a clear signal for timing decisions[2][10][16] 2. Model Name: Industry Allocation Model - **Model Construction Idea**: This model identifies sectors with potential for outperformance based on medium-term trends and specific themes, such as "distressed reversal" and "high elasticity" sectors[3][11][16] - **Model Construction Process**: 1.
