Quantitative Models and Construction Methods 1. Model Name: Comprehensive Impact Coefficient - **Model Construction Idea**: The model aims to quantify the combined impact of multiple index adjustments on individual stocks, considering the overlap and exchange of sample stocks across different indices[23][24] - **Model Construction Process**: The comprehensive impact coefficient is defined as follows: $$ effect_{\_}total_{s} = \sum_{i=1}^{n} \frac{wt_{\_}chg_{s\_i} \times fund_{\_}size_{i}}{amount_{\_}avg_{s,20}} $$ - \( wt_{\_}chg_{s\_i} \): Weight change of stock \( s \) in index \( i \) - \( fund_{\_}size_{i} \): Fund size tracking index \( i \) - \( amount_{\_}avg_{s,20} \): 20-day average trading volume of stock \( s \)[23][24] - **Model Evaluation**: The model effectively captures the correlation between the comprehensive impact coefficient and the adjustment effect, making it a valuable tool for identifying stocks with significant adjustment impacts[29] --- Model Backtesting Results 1. Comprehensive Impact Coefficient - **Key Metrics**: - Stocks with a coefficient above 1: Average excess return per period = 3.82% - Stocks with a coefficient above 2: Average excess return per period = 5.13%[2][16] - **Historical Performance**: - December 2020: Coefficient > 2, average absolute return = 13.75%, excess return = 14.64% - June 2021: Coefficient > 2, average absolute return = 10.67%, excess return = 11.33% - December 2021: Coefficient > 2, average absolute return = 6.64%, excess return = 2.83% - June 2022: Coefficient > 2, average absolute return = 10.29%, excess return = 5.02% - December 2022: Coefficient > 2, average absolute return = 8.33%, excess return = 3.40% - June 2023: Coefficient > 2, average absolute return = 0.99%, excess return = 0.90% - December 2023: Coefficient > 2, average absolute return = 4.96%, excess return = 6.55% - June 2024: Coefficient > 2, average absolute return = -1.45%, excess return = 0.57% - December 2024: Coefficient > 2, average absolute return = 2.28%, excess return = 0.96%[13][14][15] --- Quantitative Factors and Construction Methods 1. Factor Name: Weight Rules - **Factor Construction Idea**: Weight rules are applied to ensure that the influence of individual stocks or sectors within an index remains balanced and aligned with the index's design objectives[25][26] - **Factor Construction Process**: - Different indices impose specific constraints on individual stock weights, such as: - Maximum weight for a single stock (e.g., 10%, 15%) - Combined weight limits for the top N stocks (e.g., top 5 stocks ≤ 40%) - Sector weight alignment with free-float market capitalization[26][27] --- Factor Backtesting Results 1.
