Quantitative Models and Construction Methods Model Name: Index Component Adjustment Impact Model - **Model Construction Idea**: The model aims to measure the impact of index component adjustments on stock prices, considering the scale of passive products tracking the index and the average trading volume of the stocks[7][8][9]. - **Detailed Construction Process**: - The model calculates the impact of index adjustments using the following formula: $$ \mathrm{effect}_{s} = \frac{\sum_{i}^{m} wt_{in} * index_{-}scale_{i} - \sum_{i}^{n} wt_{out} * index_{-}scale_{i}}{avg_{-}amt_{s}} $$ where: - \( wt_{in} \) represents the buy weight of the stock in the index - \( wt_{out} \) represents the sell weight of the stock in the index - \( index_{-}scale_{i} \) represents the total scale of passive products tracking the index - \( avg_{-}amt_{s} \) represents the average daily trading volume of the stock over the past two weeks[7][8][9]. - **Model Evaluation**: The model effectively quantifies the potential trading impact on stocks due to index adjustments, providing valuable insights for identifying trading opportunities[7][8][9]. Model Backtesting Results - **Index Component Adjustment Impact Model**: - **Net Buy Scale**: - Shenghong Technology: 48.65 billion CNY[10] - Dongshan Precision: 47.91 billion CNY[10] - Guangqi Technology: 34.87 billion CNY[10] - **Impact Coefficient**: - Shenghong Technology: 0.57[10] - Dongshan Precision: 1.31[10] - Guangqi Technology: 3.37[10] Quantitative Factors and Construction Methods Factor Name: Impact Coefficient - **Factor Construction Idea**: The impact coefficient measures the potential impact on a stock's price due to changes in its index weight, considering the net adjustment scale and the stock's average trading volume[9][10][11]. - **Detailed Construction Process**: - The impact coefficient is calculated using the formula: $$ \text{Impact Coefficient} = \frac{\text{Net Adjustment Scale}}{\text{Average Daily Trading Volume}} $$ where: - Net Adjustment Scale is the net buy or sell scale of the stock due to index adjustments - Average Daily Trading Volume is the stock's average trading volume over the past two weeks[9][10][11]. - **Factor Evaluation**: The impact coefficient provides a clear measure of the potential price impact on stocks due to index adjustments, helping investors identify stocks that may experience significant price movements[9][10][11]. Factor Backtesting Results - **Impact Coefficient**: - **Stocks with Impact Coefficient > 2**: - Tower Group: 8.69[12] - Jiangzhong Pharmaceutical: 8.44[12] - Shanxi Drum Power: 6.99[12] - **Stocks with Impact Coefficient < -2**: - Deep Expressway: -15.65[14] - Wanhe Electric: -13.30[14] - Tianyoude Wine: -10.52[14]

- The report introduces a **comprehensive impact coefficient model** to measure the impact of multiple index adjustments on individual stocks. The model is defined as follows: $effect\_total_{s}=\sum_{i=1}^{n}\frac{wt\_chg_{s_{i}}\times fund\_size_{i}}{amount\_avg_{s_{i}}20}$ where $effect\_total_{s}$ represents the comprehensive impact coefficient of stock $s$ across sample indices, $wt\_chg_{s_{i}}$ is the estimated weight change of stock $s$ in index $i$, $fund\_size_{i}$ is the tracking scale of index $i$, and $amount\_avg_{s_{i}}20$ is the average trading volume of stock $s$ over the past 20 days[11] - The report highlights the **impact of index sample stock adjustments** on individual stocks, focusing on the December 2025 periodic adjustments of major indices such as CSI 300, CSI A500, and SSE 50. The analysis includes the calculation of the comprehensive impact coefficient for stocks being added or removed from indices, as well as the potential passive trading impact due to weight adjustments[13][14][16] - The report identifies **stocks with significant positive and negative impact coefficients** due to index adjustments. For example, stocks like Tower Group, Jiangzhong Pharmaceutical, and Zhengbang Technology have positive impact coefficients above 2, while stocks like Deep Expressway and Wanhe Electric have significant negative impact coefficients[16][17][18] - The report evaluates the **impact of weight cap adjustments** for stocks like Zhongji Xuchuang and Xinyisheng in thematic indices such as CS Artificial Intelligence and Communication Equipment. Due to exceeding the weight cap, these stocks are expected to experience passive outflows of approximately 6.3 billion yuan and 2.7 billion yuan, respectively. However, the report concludes that the negative impact is limited due to sufficient liquidity and potential inflows from other indices[5][19][20]
