- 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]

- The report introduces a quantitative model named "250-Day New High Distance" to track market trends and identify leading stocks. The model calculates the distance between the latest closing price and the highest closing price over the past 250 trading days using the formula: $ 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 in the past 250 trading days. If the latest closing price reaches a new high, the distance equals 0; otherwise, it indicates the percentage drop from the peak[10][11][12] - The report evaluates the model positively, citing its ability to capture momentum and trend-following strategies effectively. It references prior research, such as [George@2004] and insights from investment books like "Stock Market Wizard," which emphasize the importance of tracking stocks near their 52-week highs[10][18][21] - The report applies the model to major indices, showing their respective 250-Day New High Distances as of August 1, 2025: - Shanghai Composite Index: 1.54% - Shenzhen Component Index: 4.38% - CSI 300: 4.73% - CSI 500: 2.25% - CSI 1000: 1.53% - CSI 2000: 1.08% - ChiNext Index: 8.93% - STAR 50 Index: 7.99%[11][12][33] - The report identifies industries and concept indices close to their 250-Day New Highs, such as Media, Communication, Pharmaceuticals, Defense, and Steel. Concept indices like Wind Microcap Equal Weight, Electronic Equipment, CRO, and Innovative Drugs also show proximity to their 250-Day New Highs[12][14][33] - The report tracks stocks that have reached 250-Day New Highs in the past 20 trading days. A total of 1,239 stocks are identified, with the highest counts in industries like Pharmaceuticals (192 stocks), Machinery (169 stocks), and Basic Chemicals (132 stocks). The highest proportions are found in Banking (64.29%), Steel (56.60%), and Nonferrous Metals (41.94%)[19][20][34] - The report introduces a factor named "Stable New High Stocks," which selects stocks based on criteria such as analyst attention, relative price strength, price path smoothness, and sustained new highs. Specific metrics include: - Analyst attention: At least five buy or overweight ratings in the past three months - Relative price strength: Top 20% in 250-day returns - Price path smoothness: Evaluated using metrics like cumulative absolute daily returns over 120 days - Sustained new highs: Average 250-Day New High Distance over the past 120 days - Trend continuation: Average 250-Day New High Distance over the past five days[24][27][28] - The report lists 50 stocks selected as "Stable New High Stocks," with the highest counts in Manufacturing (15 stocks) and Technology (14 stocks). Examples include Shenghong Technology, Borui Pharmaceuticals, and Feilihua[28][32][34]

Quantitative Models and Construction Methods 1. Model Name: 250-Day New High Distance Model - **Model Construction Idea**: This model tracks the distance of a stock or index from its 250-day high to identify market trends and hotspots. It is based on the premise that stocks nearing their 52-week high tend to outperform, as supported by prior research such as [George@2004] and the CANSLIM methodology[11][18]. - **Model Construction Process**: The 250-day new high distance is calculated using the formula: $ 250 \text{-day new high distance} = 1 - \frac{Close_t}{ts\_max(Close, 250)} $ Where: - $ Close_t $ represents the latest closing price - $ ts\_max(Close, 250) $ represents the maximum closing price over the past 250 trading days If the latest closing price reaches a new high, the distance is 0; otherwise, the distance is positive, indicating the percentage drop from the high[11]. 2. Model Name: Stable New High Stock Screening Model - **Model Construction Idea**: This model identifies stocks with stable momentum characteristics, emphasizing smooth price paths and consistent new highs. Research suggests that smoother momentum stocks outperform those with jumpy price paths due to underreaction by investors[26]. - **Model Construction Process**: Stocks are screened from the pool of those that hit a 250-day high in the past 20 trading days. The screening criteria include: - **Analyst Attention**: At least 5 "Buy" or "Overweight" ratings in the past 3 months - **Relative Strength**: Top 20% in 250-day price performance - **Price Stability**: Evaluated using metrics such as cumulative absolute daily returns over 120 days and price path smoothness - **New High Continuity**: Average 250-day new high distance over the past 120 days - **Trend Continuity**: Average 250-day new high distance over the past 5 days Stocks meeting these criteria are ranked, and the top 50% are selected for further analysis[26][28]. --- Model Backtesting Results 1. 250-Day New High Distance Model - **Key Metrics**: - Major indices' 250-day new high distances as of July 11, 2025: - Shanghai Composite: 0.00% - Shenzhen Component: 6.95% - CSI 300: 5.67% - CSI 500: 4.79% - CSI 1000: 2.28% - CSI 2000: 0.00% - ChiNext Index: 13.46% - STAR 50 Index: 11.75%[12][13][33] 2.
