• The report includes multiple quantitative models for A-share market timing, such as "Volume Model," "Low Volatility Model," "Feature Institutional Model," "Feature Volume Model," "Smart CSI 300 Model," "Smart CSI 500 Model," "Limit-Up/Down Model," "Calendar Effect Model," "Long-Term Momentum Model," "Comprehensive Weapon V3 Model," and "Comprehensive CSI 2000 Model"[1][10][11][12][13] - The report also includes a Hong Kong market timing model, specifically the "Turnover Inverse Volatility Model"[14][73] - The construction of these models is based on principles such as price-volume relationships, acceleration and trend analysis, momentum, limit-up/down patterns, and calendar effects. The models are designed to cover short-term, medium-term, and long-term cycles, forming a multi-strategy system[8][10][11] - The report evaluates the models qualitatively, stating that timing strategies should be simple and universal, emphasizing the importance of coupling signals from different models or cycles to achieve a balance between offensive and defensive strategies[8][10][11] - The latest signals from the models indicate mixed results: some models are bullish (e.g., Volume Model, Feature Volume Model, Limit-Up/Down Model, Comprehensive Weapon V3 Model, Comprehensive CSI 2000 Model), while others are neutral or bearish (e.g., Low Volatility Model, Feature Institutional Model, Smart CSI 300 Model, Smart CSI 500 Model)[10][11][12][13] - Backtesting results for specific models or factors are not explicitly detailed in the report, but the report mentions that the "Comprehensive Weapon V3 Model" and "Comprehensive CSI 2000 Model" are bullish overall[13][72] - The Hong Kong market model, "Turnover Inverse Volatility Model," continues to show bullish signals for the Hang Seng Index[14][73]
