Quantitative Models and Construction Methods 1. Model Name: Hong Kong Stock Selection Portfolio - Model Construction Idea: The model is based on a dual-layer selection process that integrates fundamental and technical analysis. It aims to identify stocks with both fundamental support and technical resonance from an analyst-recommended stock pool[14][17] - Model Construction Process: 1. Analyst Recommendation Pool: Constructed using three types of analyst recommendation events: upward earnings forecast revisions, first-time coverage, and research reports with unexpected positive titles[17] 2. Dual-Layer Selection: - Fundamental Analysis: Select stocks with strong fundamental support - Technical Analysis: Identify stocks with technical resonance 3. Backtesting: The backtesting period is from January 1, 2010, to December 31, 2025. The portfolio assumes a fully invested state and considers transaction costs[17] - Model Evaluation: The model demonstrates strong performance with significant annualized returns and excess returns over the Hang Seng Index[17] 2. Factor Name: 250-Day New High Distance - Factor Construction Idea: This factor measures the distance of the latest closing price from the 250-day high, reflecting the momentum effect in stock prices[21][23] - Factor Construction Process: 1. Formula: $ 250\text{-Day New High Distance} = 1 - \frac{\text{Close}{t}}{\text{ts_max}(\text{Close}, 250)} $ - $\text{Close}{t}$: Latest closing price - $\text{ts_max}(\text{Close}, 250)$: Maximum closing price over the past 250 trading days 2. Interpretation: - If the latest closing price reaches a new high, the factor value is 0 - If the price falls from the high, the factor value is positive, indicating the degree of decline[23] 3. Screening Criteria: - Stocks with high analyst attention (at least five buy or overweight ratings in the past six months) - Top 20% in 250-day price change within the sample pool - Stability and trend continuation metrics, such as price path smoothness and average 250-day new high distance over the past 120 days[24] --- Model Backtesting Results 1.
