- The report introduces a quantitative model based on the "250-day new high distance" to track market trends and identify investment hotspots. 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 is 0; otherwise, it is a positive value indicating the degree of fallback [11][19][26] - The model evaluates the effectiveness of momentum and trend-following strategies, referencing studies by George (2004), William O'Neil's CANSLIM framework, and Mark Minervini's "Stock Market Wizard," which emphasize the importance of stocks near their 52-week highs as potential leaders in market uptrends [11][18][21] - A screening method for "stable new high stocks" is introduced, focusing on factors such as analyst attention, relative stock strength, price path smoothness, and sustained new highs. Key metrics 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: Evaluated using metrics like price displacement ratio - 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 5 days [26][28][29] - The report identifies 41 "stable new high stocks" based on the above criteria, with the majority belonging to cyclical and manufacturing sectors. Notable industries include non-ferrous metals and machinery [29][30][32] - Backtesting results show that cyclical and manufacturing sectors have the highest number of stocks achieving new highs, with cyclical stocks leading in non-ferrous metals and manufacturing stocks excelling in machinery [19][20][29]
