Quantitative Models and Construction Methods 1. Model Name: 250-Day New High Distance Model - Model Construction Idea: This model tracks the distance of stock prices or indices from their 250-day high to identify market trends and momentum. It is based on the principle that stocks nearing their 52-week high tend to outperform those further away from it, as highlighted in prior research by George (2004) and others[11][18]. - Model Construction Process: The formula for calculating the 250-day new high distance is: $ 250\text{-day new high distance} = 1 - \frac{Close_t}{ts_max(Close, 250)} $ Where: - $ Close_t $ is the latest closing price - $ ts_max(Close, 250) $ is the maximum closing price over the past 250 trading days If the latest closing price reaches a new high, the distance is 0. If the price has fallen from the high, the distance is a positive value representing the percentage drop[11]. - Model Evaluation: The model effectively captures momentum and trend-following characteristics, aligning with established theories in quantitative finance[11][18]. --- Model Backtesting Results 1. 250-Day New High Distance Model - Indices' 250-Day New High Distance (as of October 24, 2025): - Shanghai Composite Index: 0.00% - Shenzhen Component Index: 3.18% - CSI 300: 1.04% - CSI 500: 3.85% - CSI 1000: 2.99% - CSI 2000: 3.14% - ChiNext Index: 2.77% - STAR 50 Index: 4.99%[2][12][33] --- Quantitative Factors and Construction Methods 1. Factor Name: Stable New High Stocks Factor - Factor Construction Idea: This factor identifies stocks that exhibit stable momentum characteristics, focusing on smooth price paths and consistent new highs. It builds on research by Bali et al. (2011) and Da et al. (2012), which highlight the importance of price path smoothness and investor underreaction to information[25][28]. - Factor Construction Process: Stocks are selected from those that reached a 250-day high in the past 20 trading days. The selection criteria include: 1. Analyst Attention: At least 5 "Buy" or "Overweight" ratings in the past 3 months 2. Relative Strength: Top 20% in 250-day price performance 3. Price Stability: - Absolute value of 120-day price changes - Sum of absolute daily price changes over the past 120 days 4. New High Consistency: Average 250-day new high distance over the past 120 days 5. Trend Continuation: Average 250-day new high distance over the past 5 days Stocks meeting these criteria are ranked, and the top 50 are selected[25][28]. - Factor Evaluation: The factor emphasizes smooth momentum and consistent performance, which are less likely to attract excessive attention, potentially leading to stronger returns[25][28]. --- Factor Backtesting Results 1. Stable New High Stocks Factor - Sector Distribution of Selected Stocks: - Technology: 18 stocks (most from the electronics industry) - Manufacturing: 14 stocks (most from the machinery industry)[29][34] - Examples of Selected Stocks: - Shannon Semiconductor, Foxconn Industrial Internet, and H&T Intelligent Control are among the 50 selected stocks[29][34].
