Quantitative Models and Construction Methods 1. Model Name: Southbound Capital Monthly Net Purchase Model - **Model Construction Idea**: This model uses the monthly net purchase amount of Southbound Capital to evaluate its effectiveness in driving sector rotation in the Hong Kong stock market[12][40]. - **Model Construction Process**: - The net purchase amount for each stock is calculated as: $$ S_{i,t} = (N_{i,t} - N_{i,t-1}) * P_{i,t} $$ Where: \( N_{i,t} \) = Southbound Capital holdings of stock \( i \) on day \( t \)[37] \( P_{i,t} \) = Average price of stock \( i \) on day \( t \)[37] - The sector-level net purchase amount is aggregated as: $$ Ind_{t} = \sum S_{i,t} $$ Where \( Ind_{t} \) represents the cumulative net purchase amount for the sector on day \( t \)[37]. - **Model Evaluation**: The model demonstrates a positive Rank IC mean, indicating its effectiveness in sector rotation strategies[40]. 2. Model Name: Market Cap-Adjusted Southbound Capital Model - **Model Construction Idea**: Adjust the Southbound Capital net purchase amount by sector market capitalization to improve strategy performance[40]. - **Model Construction Process**: - The net purchase amount is calculated as in the previous model. - Adjustments are made based on the market capitalization of each sector to normalize the influence of large-cap sectors[40]. - **Model Evaluation**: This adjustment improves strategy returns and reduces maximum drawdown compared to the unadjusted model[46][48]. 3. Model Name: Three-Year Percentile Southbound Capital Model - **Model Construction Idea**: Use the three-year percentile rank of Southbound Capital net purchases to identify sector preferences over a longer historical period[40]. - **Model Construction Process**: - Calculate the three-year percentile rank of the net purchase amount for each sector. - Rank sectors based on their percentile values to determine rotation preferences[40]. - **Model Evaluation**: The three-year percentile model provides a longer-term perspective but shows slightly lower Rank IC values compared to the unadjusted model[40]. 4. Model Name: Market Cap-Adjusted Three-Year Percentile Model - **Model Construction Idea**: Combine market capitalization adjustments with the three-year percentile rank to enhance strategy robustness[40]. - **Model Construction Process**: - Apply market cap adjustments to the three-year percentile rank of net purchases. - Rank sectors based on the adjusted values to guide rotation decisions[40]. - **Model Evaluation**: This model achieves the best overall performance, with the highest Sharpe ratio and IR among all tested strategies[46][48]. --- Model Backtest Results 1.
