• 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]
