- The "Hong Kong Stock Selection Portfolio" model aims to construct a portfolio by dual-layer screening based on fundamental and technical aspects of analyst-recommended stocks. The analyst recommendation pool is built using events such as upward earnings forecast revisions, initial analyst coverage, and unexpected research report titles. Stocks with both fundamental support and technical resonance are selected to form the portfolio. The backtesting period is from January 1, 2010, to December 31, 2025, with an annualized return of 19.08% and an excess return of 18.06% relative to the Hang Seng Index[13][15][19] - The "Stable New High Stock Screening" factor identifies stocks that have reached a 250-day high in the past 20 trading days. The calculation formula for the 250-day new high distance 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. A value of 0 indicates a new high, while positive values represent the degree of fallback. Stocks are further filtered based on analyst attention, relative price strength, price stability, and trend continuation metrics[20][22][23] - The "Stable New High Stock Screening" factor uses additional criteria for filtering: - Analyst attention: At least 5 buy or overweight ratings in the past 6 months - Relative price strength: Top 20% in 250-day returns within the sample pool - Price stability: Evaluated using metrics like price path smoothness and average 250-day new high distance over the past 120 days - Trend continuation: Average 250-day new high distance over the past 5 days[23] - The backtesting results for the "Hong Kong Stock Selection Portfolio" model show annualized return of 19.08%, excess return of 18.06%, and various performance metrics such as IR of 1.19, tracking error of 14.60%, and maximum drawdown of 23.73%[19] - The "Stable New High Stock Screening" factor identified stocks across sectors, with the highest number in the cyclical sector (8 stocks), followed by technology (2 stocks), manufacturing (1 stock), consumer (1 stock), and healthcare (1 stock)[22][23][27]
