• The "Competitive Advantage Portfolio" utilizes a competitive barrier analysis framework to categorize industries into four types: "Barrier Shield," "Highly Competitive," "Steady Progress," and "Seeking Breakthrough." The strategy focuses on identifying "sole leading" companies in "Barrier Shield" industries and "cooperative win-win" companies in industries without clear leaders. For non-"Barrier Shield" industries, it targets "efficient operation" companies that perform well even in competitive environments[11][12] - The "Margin of Safety Portfolio" emphasizes the internal factors of a company, focusing on creating entry barriers to ensure unique market positions and sustainable profitability. It calculates the intrinsic value of a company based on its profitability, selecting the top 50 stocks with the highest margin of safety from a pool of stocks with comprehensive competitive advantages. The portfolio is adjusted on May 1, September 1, and November 1 each year[17][19] - The "Dividend Low Volatility Adjusted Portfolio" aims to avoid the "high dividend trap" by considering the sustainability of company earnings and long-term value. It uses dividend yield predictions and negative screening to exclude stocks with extreme price performance or abnormal debt ratios[23] - The "AEG Valuation Potential Portfolio" uses the AEG_EP factor to select the top 100 stocks, then narrows it down to the top 50 stocks with high dividend reinvestment ratios. This strategy invests in companies whose growth potential is not yet fully recognized by the market. The AEG model calculates abnormal earnings growth as follows: $\begin{array}{c} A E G=Y_{t}-N_{t}=(E_{t}+r*D P S_{t-1})-(1+r)*E_{t-1} \\ \frac{V_{0}}{E_{1}}=\frac{1}{r}+\frac{1}{r}*\frac{\left(\frac{A E G_{2}}{1+r}+\frac{A E G_{3}}{(1+r)^{2}}+\frac{A E G_{4}}{(1+r)^{3}}+\cdots\right)}{E_{1}} \end{array}$ where $E_1$ is the first period's earnings and $V_0$ is the current market value[28][29][31] - The "Cash Cow Portfolio" uses the CFOR analysis system to evaluate a company's profitability and cash generation efficiency. It focuses on the stability of free cash profit ratio, operating asset return rate, net profit margin, and total asset turnover rate, selecting high-quality stocks from the CSI 800 index[34][35][36] - The "Distressed Reversal Portfolio" captures short-term valuation fluctuations by utilizing inventory cycles to depict company reversals, considering accelerated recovery and undervaluation. It constructs a top 50 portfolio based on valuation improvement[41][43] Model Backtest Results - Competitive Advantage Portfolio: Annualized return since 2019 is 19.84%, Sharpe ratio 0.93, IR 0.09, maximum drawdown -19.32%, Calmar ratio 1.03[16] - Margin of Safety Portfolio: Annualized return since 2019 is 23.16%, Sharpe ratio 1.15, IR 0.16, maximum drawdown -16.89%, Calmar ratio 1.37[21] - Dividend Low Volatility Adjusted Portfolio: Annualized return since 2019 is 16.87%, Sharpe ratio 1.00, IR 0.17, maximum drawdown -21.61%, Calmar ratio 0.78[24] - AEG Valuation Potential Portfolio: Annualized return since 2019 is 25.36%, Sharpe ratio 1.16, IR 0.15, maximum drawdown -24.02%, Calmar ratio 1.06[33] - CSI 800 Cash Cow Portfolio: Annualized return since 2019 is 13.42%, Sharpe ratio 0.67, IR 0.09, maximum drawdown -19.80%, Calmar ratio 0.68[39] - Distressed Reversal Portfolio: Annualized return since 2019 is 24.53%, Sharpe ratio 0.99, IR 0.15, maximum drawdown -33.73%, Calmar ratio 0.73[43]
