• The report discusses multiple quantitative timing models for A-shares, including short-term, medium-term, and long-term models. The short-term models include the Volume Model (neutral for all broad-based indices), Feature Institutional Model (bullish), Feature Volume Model (bearish), and Smart Algorithm Models (bullish for CSI 300, bearish for CSI 500)[1][12][77]. Medium-term models include the Limit-Up-Limit-Down Model (neutral) and the Up-Down Return Difference Model (bullish for all broad-based indices)[13][78]. The long-term model, the Long-Term Momentum Model, is bullish[14][79]. Comprehensive models like the A-Share Comprehensive Weapon V3 Model and the A-Share Comprehensive CSI 2000 Model are bearish[15][80] - For Hong Kong stocks, the medium-term models include the Turnover-to-Volatility Model (bullish) and the Hang Seng Index Up-Down Return Difference Model (neutral)[16][81] - The report emphasizes that timing strategies are not achieved through a single model but require a multi-cycle, multi-strategy system. It highlights the use of price-volume, acceleration, trend, momentum, and limit-up-limit-down perspectives to construct eight major models for market timing[9] - Backtesting results for the Double-Bottom Pattern show a weekly return of 0.29%, outperforming the Shanghai Composite Index by 0.27% during the same period.
