Quantitative Models and Construction Methods - Model Name: Davis Double Play Model Construction Idea: The strategy involves buying stocks with growth potential at a low PE ratio and selling them after growth materializes and PE increases, achieving a multiplier effect through EPS and PE growth ("double play")[8] Model Construction Process: The strategy evaluates stocks based on PEG (Price/Earnings to Growth) to assess pricing rationality. Companies with accelerating earnings growth are targeted, as higher growth rates theoretically justify higher valuations, effectively controlling downside PE risks[8] Model Evaluation: The strategy demonstrated strong stability during the backtesting period, with annual excess returns exceeding 11% in all seven complete years from 2010 to 2017[10] - Model Name: Net Profit Gap Strategy Model Construction Idea: This strategy combines fundamental and technical analysis, focusing on "net profit surprises" and "gap behavior" after earnings announcements[13] Model Construction Process: Stocks are screened based on earnings surprises from the past two months' earnings forecasts and financial reports. The top 50 stocks with the highest gap magnitude on the first trading day post-announcement are selected to construct an equal-weight portfolio[13] Model Evaluation: The strategy achieved consistent high returns, with annualized excess returns of 27.17% since 2010, showcasing strong performance stability[17] - Model Name: CSI 300 Enhanced Portfolio Model Construction Idea: The model is based on investor preferences categorized into GARP, growth, and value styles. It uses PBROE and PEG factors to identify undervalued stocks with strong profitability and growth potential[19] Model Construction Process: - PBROE Factor: Constructed using the difference in percentiles between PB (Price-to-Book) and ROE (Return on Equity) to identify stocks with low valuation and high profitability[19] - PEG Factor: Constructed using the difference in percentiles between PE (Price-to-Earnings) and growth rate to find undervalued stocks with reliable growth potential[19] Model Evaluation: The model demonstrated stable excess returns in historical backtesting, aligning with investor preferences for growth and value stocks[23] --- Model Backtesting Results - Davis Double Play - Annualized Return: 26.45% - Annualized Excess Return: 21.08% - This Year Absolute Return: 11.24% - This Year Excess Return (vs CSI 500): 12.19% - Weekly Excess Return (20250526-20250530): -3.02% - Full Sample Excess Return: 21.71% - Maximum Relative Drawdown: -20.14% - Return-to-Drawdown Ratio: 1.08[10][11] - Net Profit Gap Strategy - Annualized Return: 28.71% - Annualized Excess Return: 27.17% - This Year Absolute Return: 17.81% - This Year Excess Return: 18.76% - Weekly Excess Return (20250526-20250530): 0.57% - Full Sample Excess Return: 27.17% - Maximum Relative Drawdown: -37.12% - Return-to-Drawdown Ratio: 0.73[15][17] - CSI 300 Enhanced Portfolio - Annualized Return: 9.47% - Annualized Excess Return: 9.00% - This Year Absolute Return: 8.02% - This Year Excess Return: 10.42% - Weekly Excess Return (20250526-20250530): 1.79% - Monthly Excess Return (20250501-20250530): 4.03% - Full Sample Excess Return: 9.00% - Maximum Relative Drawdown: -9.18% - Return-to-Drawdown Ratio: 0.98[21][23] --- Quantitative Factors and Construction Methods - Factor Name: PBROE Factor Construction Idea: Identifies stocks with low valuation and high profitability[19] Factor Construction Process: Calculated as the difference in percentiles between PB and ROE[19] - Factor Name: PEG Factor Construction Idea: Targets undervalued stocks with reliable growth potential[19] Factor Construction Process: Calculated as the difference in percentiles between PE and growth rate[19] --- Factor Backtesting Results - PBROE Factor - Incorporated into CSI 300 Enhanced Portfolio, contributing to stable excess returns[19][23] - PEG Factor - Incorporated into CSI 300 Enhanced Portfolio, contributing to stable excess returns[19][23]
