Quantitative Models and Construction - Model Name: Volume Model Construction Idea: This model uses trading volume as a key indicator to predict market trends in the short term[12][65] Construction Process: The model evaluates the trading volume of broad-based indices to generate buy or sell signals. A higher trading volume relative to historical averages indicates a "bullish" signal, while lower volumes may indicate neutrality or bearishness[12][65] Evaluation: The model is effective in capturing short-term market momentum and is widely applicable across broad indices[12][65] - Model Name: Low Volatility Model Construction Idea: This model focuses on the volatility of indices to assess market stability and predict trends[12][65] Construction Process: The model calculates the historical volatility of indices over a defined period. If the volatility is low, the model remains neutral, indicating a stable market environment[12][65] Evaluation: The model is useful for identifying periods of market stability but may lack predictive power during high-volatility phases[12][65] - Model Name: Institutional Feature Model (Top Trader) Construction Idea: This model analyzes institutional trading patterns to predict market movements[12][65] Construction Process: The model tracks the trading activity of institutional investors, particularly their buying and selling patterns. A high level of institutional selling generates a "bearish" signal[12][65] Evaluation: The model provides insights into institutional sentiment but may be less effective in retail-dominated markets[12][65] - Model Name: Momentum Model Construction Idea: This model leverages price momentum to predict long-term market trends[14][67] Construction Process: The model calculates the rate of price change over a long-term horizon. Positive momentum generates a "bullish" signal, while negative momentum indicates bearishness[14][67] Evaluation: The model is effective in identifying long-term trends but may lag during sudden market reversals[14][67] - Model Name: A-Share Comprehensive Weapon V3 Model Construction Idea: This is a composite model that integrates multiple signals across different time horizons[15][68] Construction Process: The model combines short-term, medium-term, and long-term signals from various sub-models (e.g., volume, momentum, institutional features) to generate an overall market outlook[15][68] Evaluation: The model balances short-term and long-term perspectives, making it robust for comprehensive market analysis[15][68] - Model Name: Hang Seng Turnover-to-Volatility Model Construction Idea: This model uses the ratio of turnover to volatility to predict medium-term trends in the Hong Kong market[16][69] Construction Process: The model calculates the turnover-to-volatility ratio for the Hang Seng Index. A higher ratio indicates a "bullish" signal, suggesting strong market participation relative to risk[16][69] Evaluation: The model is effective in capturing medium-term trends but may be less responsive to short-term fluctuations[16][69] Model Backtesting Results - Volume Model: All broad-based indices showed "bullish" signals in the short term[12][65] - Low Volatility Model: Neutral signals were observed, indicating stable market conditions[12][65] - Institutional Feature Model: Bearish signals were generated due to high institutional selling activity[12][65] - Momentum Model: Long-term "bullish" signals were observed, indicating positive price momentum[14][67] - A-Share Comprehensive Weapon V3 Model: Overall "bullish" signals were generated, reflecting a positive market outlook[15][68] - Hang Seng Turnover-to-Volatility Model: "Bullish" signals were observed, suggesting optimism in the Hong Kong market[16][69]
