Quantitative Models and Construction - **Model Name**: Competitive Advantage Portfolio **Construction Idea**: Incorporates competitive environment and strategic factors into stock selection, focusing on industries with distinct competitive characteristics[10][11] **Construction Process**: 1. Classify industries into four types: "Barrier Shield", "Intense Competition", "Steady Progress", and "Seeking Breakthrough"[10] 2. Focus on "Barrier Shield" industries to identify "dominant leaders" and "cooperative win-win" companies[10] 3. Combine "dominant leaders + cooperative win-win" stocks with "efficient operators" from non-barrier industries to form the portfolio[11] **Evaluation**: Provides a unique value quantification perspective beyond traditional factor investing[10] - **Model Name**: Margin of Safety Portfolio **Construction Idea**: Focuses on internal value estimation and competitive advantage to ensure sustainable profitability[15] **Construction Process**: 1. Calculate intrinsic value using profitability metrics like ROIC and NOPAT[15] 2. Select top 50 stocks with the highest margin of safety from a competitive advantage pool[15] 3. Weight stocks by dividend yield to maximize portfolio safety margin[15][17] **Evaluation**: Emphasizes reliable intrinsic value estimation and sustainable competitive advantage[15] - **Model Name**: Dividend Low Volatility Adjusted Portfolio **Construction Idea**: Avoids "high dividend traps" by considering dividend sustainability and excluding extreme cases[21] **Construction Process**: 1. Predict dividend yield and exclude stocks with extreme price performance or abnormal debt ratios[21] 2. Optimize portfolio by focusing on stocks with stable dividend yields[21] **Evaluation**: Addresses the risks of chasing high dividend yields without considering long-term value[21] - **Model Name**: AEG Valuation Potential Portfolio **Construction Idea**: Utilizes abnormal earnings growth (AEG) to capture valuation potential[25] **Construction Process**: 1. Calculate AEG using the formula: $$\begin{array}{c}{{A E G=Y_{t}-N_{t}=(E_{t}+r*D P S_{t-1})-(1+r)*E_{t-1}}}\\ {{\frac{V_{0}}{E_{1}}=\frac{1}{r}+\frac{1}{r}*\frac{\left(\frac{A E G_{2}}{1+r}+\frac{A E G_{3}}{(1+r)^{2}}+\frac{A E G_{4}}{(1+r)^{3}}+\cdots\right)}}}\\ {{\frac{E_{1}}{E_{1}}}}\end{array}$$[25] 2. Select top 100 stocks based on AEG_EP factor, then narrow down to top 50 with high dividend reinvestment/P ratio[29] **Evaluation**: Captures undervalued growth potential in companies overlooked by the market[25][29] - **Model Name**: Cash Cow Portfolio **Construction Idea**: Evaluates companies' cash generation efficiency using CFOR analysis[32] **Construction Process**: 1. Use CFOR metrics to assess free cash flow stability and operational asset returns[32] 2. Combine high-quality stocks from non-financial sectors with ROE above the 40th percentile[33] 3. Select stocks with low volatility and valuation factors for final portfolio construction[33] **Evaluation**: Provides a comprehensive view of operational performance and financial stability[32] - **Model Name**: Distress Reversal Portfolio **Construction Idea**: Captures valuation-driven short-term fluctuations and recovery potential[39] **Construction Process**: 1. Use inventory cycles to identify distress reversal opportunities[39] 2. Combine factors like accelerated recovery and undervaluation to select top 50 stocks[39] **Evaluation**: Complements momentum strategies by focusing on valuation-driven returns during downturns[39] --- Model Backtesting Results - **Competitive Advantage Portfolio**: Annualized return 20.36%, Sharpe ratio 0.95, IR 0.12, max drawdown -19.32%, Calmar ratio 1.05[14] - **Margin of Safety Portfolio**: Annualized return 23.37%, Sharpe ratio 1.17, IR 0.13, max drawdown -16.89%, Calmar ratio 1.38[19] - **Dividend Low Volatility Adjusted Portfolio**: Annualized return 16.81%, Sharpe ratio 0.98, IR 0.16, max drawdown -21.61%, Calmar ratio 0.78[22] - **AEG Valuation Potential Portfolio**: Annualized return 24.88%, Sharpe ratio 1.13, IR 0.17, max drawdown -24.02%, Calmar ratio 1.04[31] - **Cash Cow Portfolio**: Annualized return 14.15%, Sharpe ratio 0.71, IR 0.10, max drawdown -19.80%, Calmar ratio 0.71[37] - **Distress Reversal Portfolio**: Annualized return 25.17%, Sharpe ratio 1.01, IR 0.15, max drawdown -33.73%, Calmar ratio 0.75[41]
