Quantitative Models and Construction Methods Model Name: Guosen JinGong Index Enhanced Portfolio - **Model Construction Idea**: The model aims to outperform its respective benchmarks by constructing enhanced portfolios based on multiple factors[12][13] - **Model Construction Process**: The construction process includes three main components: return prediction, risk control, and portfolio optimization. The model uses the following optimization formula to construct the Maximized Factor Exposure (MFE) portfolio: $$ \begin{array}{ll} \text{max} & f^{T} w \\ \text{s.t.} & s_{l} \leq X(w - w_{b}) \leq s_{h} \\ & h_{l} \leq H(w - w_{b}) \leq h_{h} \\ & w_{l} \leq w - w_{b} \leq w_{h} \\ & b_{l} \leq B_{b} w \leq b_{h} \\ & \mathbf{0} \leq w \leq l \\ & \mathbf{1}^{T} w = 1 \end{array} $$ where \( f \) represents the factor values, \( w \) is the stock weight vector, \( X \) is the factor exposure matrix, \( H \) is the industry exposure matrix, and \( B_{b} \) is the 0-1 vector indicating whether a stock is part of the benchmark index[41][42][43] - **Model Evaluation**: The model is designed to control various exposures and constraints, making it more likely to achieve stable and reliable performance in real-world conditions[41][42][43] Model Backtesting Results - **Guosen JinGong Index Enhanced Portfolio**: - **CSI 300 Index Enhanced Portfolio**: Weekly excess return 0.83%, annual excess return 5.09%[6][15] - **CSI 500 Index Enhanced Portfolio**: Weekly excess return 1.13%, annual excess return 7.75%[6][15] - **CSI 1000 Index Enhanced Portfolio**: Weekly excess return 1.86%, annual excess return 11.66%[6][15] - **CSI A500 Index Enhanced Portfolio**: Weekly excess return 1.24%, annual excess return 7.78%[6][15] Quantitative Factors and Construction Methods Factor Name: Single-Quarter ROE - **Factor Construction Idea**: Measures the return on equity for a single quarter to evaluate a company's profitability[18] - **Factor Construction Process**: $$ \text{Single-Quarter ROE} = \frac{\text{Net Income} \times 2}{\text{Beginning Equity} + \text{Ending Equity}} $$ where net income is the net profit attributable to shareholders, and equity is the shareholders' equity at the beginning and end of the quarter[18] - **Factor Evaluation**: This factor is effective in capturing the profitability of companies and has shown good performance in various index spaces[18] Factor Name: Delta ROE - **Factor Construction Idea**: Measures the change in return on equity compared to the same quarter of the previous year to capture improvements or deteriorations in profitability[18] - **Factor Construction Process**: $$ \text{Delta ROE} = \text{Current Quarter ROE} - \text{ROE of the Same Quarter Last Year} $$ where ROE is calculated as above[18] - **Factor Evaluation**: This factor is useful for identifying companies with improving or deteriorating profitability trends[18] Factor Backtesting Results - **CSI 300 Index Space**: - **Single-Quarter ROE**: Weekly excess return 0.64%, monthly excess return 1.78%, annual excess return 3.31%, historical annualized return 4.34%[20] - **Delta ROE**: Weekly excess return 0.41%, monthly excess return 1.59%, annual excess return 3.58%, historical annualized return 3.62%[20] - **CSI 500 Index Space**: - **Single-Quarter ROE**: Weekly excess return 0.35%, monthly excess return 1.14%, annual excess return 1.39%, historical annualized return 5.12%[22] - **Delta ROE**: Weekly excess return 0.89%, monthly excess return 1.41%, annual excess return 2.54%, historical annualized return 7.27%[22] - **CSI 1000 Index Space**: - **Single-Quarter ROE**: Weekly excess return 1.75%, monthly excess return 2.65%, annual excess return -1.60%, historical annualized return 7.78%[24] - **Delta ROE**: Weekly excess return 1.78%, monthly excess return 1.50%, annual excess return 3.83%, historical annualized return 8.66%[24] - **CSI A500 Index Space**: - **Single-Quarter ROE**: Weekly excess return 0.84%, monthly excess return 2.37%, annual excess return 3.03%, historical annualized return 2.79%[26] - **Delta ROE**: Weekly excess return 0.75%, monthly excess return 1.77%, annual excess return 3.11%, historical annualized return 3.47%[26] - **Public Fund Heavy Index Space**: - **Single-Quarter ROE**: Weekly excess return 0.57%, monthly excess return 1.41%, annual excess return 0.99%, historical annualized return 2.52%[28] - **Delta ROE**: Weekly excess return 1.03%, monthly excess return 1.71%, annual excess return 3.79%, historical annualized return 3.64%[28]
