- 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]

- The report introduces a quantitative model named "250-day new high distance" to track market trends and identify investment hotspots. The model is based on momentum and trend-following strategies, inspired by research from George (2004) and methodologies like CANSLIM and "Stock Wizard". The calculation formula is: $ 250\text{-day new high distance} = 1 - \frac{\text{Close}_{t}}{\text{ts\_max(Close, 250)}} $ where $\text{Close}_{t}$ represents the latest closing price, and $\text{ts\_max(Close, 250)}$ is the maximum closing price over the past 250 trading days. If the latest closing price hits a new high, the distance equals 0; otherwise, it is a positive value indicating the degree of fallback from the peak price [11][19][23] - The report evaluates the model positively, emphasizing its ability to capture market trends and identify leading stocks in various industries and sectors. It highlights the effectiveness of momentum strategies and the importance of tracking stocks that consistently hit new highs [11][18][23] - The report provides backtesting results for the "250-day new high distance" model. As of November 28, 2025, major indices such as the Shanghai Composite Index, Shenzhen Component Index, CSI 300, CSI 500, CSI 1000, CSI 2000, ChiNext Index, and STAR 50 Index have respective distances of 3.50%, 5.40%, 4.66%, 6.85%, 4.10%, 2.78%, 8.17%, and 13.77% from their 250-day highs [12][31][32] - The report introduces a factor-based stock selection methodology for identifying "stable new high stocks". The factors include analyst attention (at least 5 buy or overweight ratings in the past 3 months), relative stock strength (top 20% in 250-day returns), price path smoothness (measured by price displacement ratio), and trend sustainability (average 250-day new high distance over the past 120 days and past 5 days). Stocks are ranked based on these criteria, and the top 50% are selected [23][26][27] - The report evaluates the factor-based methodology positively, citing research by Turan G Bali et al. (2011) and Da, Gurun et al. (2012) that demonstrate the superior performance of stocks with smooth price paths and strong momentum effects [23][26][27] - Backtesting results for the factor-based methodology show that 26 stocks were selected as "stable new high stocks" for the week ending November 28, 2025. These include stocks from sectors such as cyclical industries (e.g., non-ferrous metals), manufacturing (e.g., construction), and others. Examples include Zhongji Xuchuang, Guangku Technology, and Zhongkuang Resources [27][30][32]
