Quantitative Models and Construction Methods 1. Model Name: Multi-dimensional Timing Model (Version 1) - **Model Construction Idea**: The model integrates four dimensions—funding, technical, valuation, and sentiment—to provide directional views on the A-share market[1][2] - **Model Construction Process**: The model combines signals from the four dimensions to determine market timing decisions. Each dimension includes specific indicators, such as option PCR, implied volatility, and futures positions for sentiment, and Bollinger Bands and individual stock movements for technical analysis[30] - **Model Evaluation**: The model demonstrated strong performance in capturing upward trends while avoiding significant market volatility[2][10] 2. Model Name: Multi-dimensional Timing Model (Version 2) - **Model Construction Idea**: This version expands the original model by adding a fundamental dimension to capture bottom-buying opportunities and enriching the sentiment dimension with new indicators[1][84] - **Model Construction Process**: - The sentiment dimension was expanded to include futures basis and main funds indicators - The fundamental dimension was introduced to identify bottom signals based on macroeconomic indicators like CPI, PMI, and EPU - The model integrates five dimensions: funding, technical, valuation, sentiment, and fundamentals[84] - **Model Evaluation**: The expanded model achieved higher annualized returns and maintained similar levels of volatility and drawdown compared to the original version[85][88] --- Model Backtesting Results 1. Multi-dimensional Timing Model (Version 1) - **Annualized Return**: 24.57%[14] - **Annualized Volatility**: 21.54%[14] - **Maximum Drawdown**: -28.46%[14] - **Sharpe Ratio**: 1.14[14] 2. Multi-dimensional Timing Model (Version 2) - **Annualized Return**: 26.69%[85] - **Annualized Volatility**: 21.48%[85] - **Maximum Drawdown**: -28.46%[85] - **Sharpe Ratio**: 1.24[85] --- Quantitative Factors and Construction Methods 1. Factor Name: Futures Basis (Sentiment Dimension) - **Factor Construction Idea**: The futures basis reflects price information in the futures market and acts as a sentiment amplifier during extreme market conditions[3][32] - **Factor Construction Process**: - Basis = Futures Price - Spot Price - Annualized basis rate is calculated to reduce the impact of contract expiration - Weighted average of the four contracts (current month, next month, current quarter, next quarter) based on open interest[32] - **Factor Evaluation**: The factor is suitable for mean-reversion strategies, with signals generated during overbought or oversold conditions[40] 2. Factor Name: Main Funds (Sentiment Dimension) - **Factor Construction Idea**: This factor captures the flow of main funds in the stock market, reflecting high-selling and low-buying behavior[3][50] - **Factor Construction Process**: - Signals are derived from smoothed 20-day moving averages of net fund inflows and institutional active buying - Positive signals indicate buying opportunities, while negative signals suggest selling[51][54] - **Factor Evaluation**: The factor is effective for momentum strategies, with a high win rate but relatively low payoff ratio[57] 3. Factor Name: Fundamental Bottom Signal (Fundamental Dimension) - **Factor Construction Idea**: This factor identifies bottom-buying opportunities based on macroeconomic indicators, assuming that poor fundamentals often precede market recoveries[4][76] - **Factor Construction Process**: - Signals are triggered when CPI, PMI, and EPU simultaneously indicate weakening fundamentals - A one-quarter window after the bottom signal is used for long positions[76][83] - **Factor Evaluation**: The factor demonstrates high win rates and payoff ratios in bottom-buying scenarios, significantly outperforming the benchmark[83] --- Factor Backtesting Results 1. Futures Basis - **Annualized Return**: 19.06%[50] - **Annualized Volatility**: 20.85%[50] - **Maximum Drawdown**: -31.31%[50] - **Sharpe Ratio**: 0.91[50] 2. Main Funds - **Annualized Return**: 8.75%[60] - **Annualized Volatility**: 19.19%[60] - **Maximum Drawdown**: -30.57%[60] - **Sharpe Ratio**: 0.46[60] 3. Fundamental Bottom Signal - **Annualized Return**: 12.48%[83] - **Annualized Volatility**: 13.27%[83] - **Maximum Drawdown**: -22.62%[83] - **Sharpe Ratio**: 0.94[83]
