- The report tracks the performance of Guosen JinGong's index enhancement portfolios and public fund index enhancement products, alongside monitoring the performance of common stock selection factors across different stock selection spaces [12][13][16] - Guosen JinGong's index enhancement portfolios are constructed based on three main components: return prediction, risk control, and portfolio optimization. These portfolios are benchmarked against indices such as CSI 300, CSI 500, CSI 1000, and CSI A500 [13][15] - The MFE (Maximized Factor Exposure) portfolio is used to test the effectiveness of individual factors under real-world constraints. The optimization model maximizes single-factor exposure while controlling for style, industry, stock weight deviations, and other constraints. The formula for the optimization model is: $\begin{array}{ll}max&f^{T}\ w\\ s.t.&s_{l}\leq X(w-w_{b})\leq s_{h}\\ &h_{l}\leq H(w-w_{b})\leq h_{h}\\ &w_{l}\leq w-w_{b}\leq w_{h}\\ &b_{l}\leq B_{b}w\leq b_{h}\\ &\mathbf{0}\leq w\leq l\\ &\mathbf{1}^{T}\ w=1\end{array}$ where `f` represents factor values, `w` is the stock weight vector, and constraints include style exposure (`X`), industry exposure (`H`), stock weight deviation (`w`), and component stock weight limits (`B_b`) [40][41][42] - The factor library includes over 30 factors categorized into valuation, reversal, growth, profitability, liquidity, corporate governance, and analyst dimensions. Examples include BP (Net Asset/Market Cap), single-quarter EP (Net Profit/Market Cap), and EPTTM (TTM Net Profit/Market Cap) [17][18] - Factor performance varies across different stock selection spaces. For CSI 300, factors like single-quarter EP, EPTTM, and expected EPTTM performed well recently, while factors like three-month volatility and expected net profit QoQ performed poorly [19][20] - For CSI 500, factors such as single-quarter ROE, DELTAROE, and single-quarter EP showed strong performance recently, whereas factors like one-year momentum and three-month reversal underperformed [21][22] - In the CSI 1000 space, factors like standardized unexpected earnings, EPTTM, and single-quarter EP performed well, while factors like non-liquidity impact and three-month institutional coverage lagged [23][24] - For CSI A500, factors such as expected EPTTM, single-quarter ROE, and expected PEG showed strong performance, while factors like one-year momentum and expected net profit QoQ underperformed [25][26] - In the public fund heavy index space, factors like expected PEG, expected EPTTM, and single-quarter EP performed well recently, while factors like one-month reversal and one-month volatility performed poorly [27][28] - Public fund index enhancement products are tracked for their excess returns relative to benchmarks. For CSI 300 products, the highest weekly excess return was 1.02%, and the lowest was -0.37%, with a median of 0.08% [29][33] - CSI 500 products showed a weekly excess return range of 1.87% to -0.44%, with a median of 0.38% [34][35] - CSI 1000 products had a weekly excess return range of 1.06% to -0.43%, with a median of 0.38% [36][37] - CSI A500 products showed a weekly excess return range of 0.73% to -0.19%, with a median of 0.17% [38][39]

Quantitative Models and Construction Methods 1. Model Name: Optimization Replication - **Model Construction Idea**: Simplify the replication of index returns into an optimization model that minimizes tracking error[31][32] - **Model Construction Process**: 1. Define the return sequence of the portfolio as: $ \tilde{R}_{t} = \Sigma_{i=1}^{M} \widetilde{W}_{i,t} \cdot Y_{i,t} = Y_{t} \cdot \overline{W}_{t} $ where $ \widetilde{W}_{i,t} $ represents the weight of asset $i$ at time $t$, and $Y_{i,t}$ is the return of asset $i$ at time $t$[31] 2. Minimize the tracking error (TE): $ w = arg\,min\;TE $ $ TE = \frac{1}{T} \Sigma_{t=1}^{T} (\tilde{R}_{t} - R_{t})^2 $ where $R_{t}$ is the benchmark return at time $t$[32] 3. Add constraints: - Full investment: $ \Sigma_{i=1}^{N} w_{i} = 1 $ - Non-negativity: $ 0 \leq w_{i} \leq 1 $[33][35] 4. Incorporate style and industry neutrality constraints to reduce overfitting: $ z_{low} \leq \frac{X_{s}^{T}w - X_{s}^{T}\tilde{w}}{s_{b}} \leq z_{up} $ $ w_{low}^{I} \leq X_{I}^{T}w - X_{I}^{T}\bar{w} \leq w_{up}^{I} $[36] 5. Solve the optimization problem to determine the weights of individual stocks[37] 2. Model Name: Pair Trading - **Model Construction Idea**: Identify pairs of stocks or sectors with similar trends and exploit mean-reversion characteristics to generate excess returns[57] - **Model Construction Process**: 1. Identify pairs of stocks or sectors with stable relationships based on quantitative or fundamental analysis 2. Overweight weaker-performing assets and underweight stronger-performing ones 3. Capture excess returns when the price spread reverts to its mean, particularly during events like macroeconomic data releases or seasonal effects[57] --- Model Backtesting Results 1. Optimization Replication - **Annualized Return**: 5.76% - **Excess Return**: 3.74% - **Sharpe Ratio**: 0.41 - **Excess Drawdown**: 3.86% - **Excess Win Rate**: 72% - **Information Ratio (IR)**: 1.51 - **Tracking Error**: 2.22%[23][27] --- Quantitative Factors and Construction Methods 1. Factor Name: Quantitative Multi-Factor - **Factor Construction Idea**: Select long-term effective alpha factors and construct a multi-factor portfolio to achieve stable excess returns[46] - **Factor Construction Process**: 1. Define the multi-factor model: $ \begin{bmatrix} r_{1} \\ r_{2} \\ \vdots \\ r_{n} \end{bmatrix} = \begin{bmatrix} x_{11} \\ x_{21} \\ \vdots \\ x_{n1} \end{bmatrix} f_{1} + \begin{bmatrix} x_{12} \\ x_{22} \\ \vdots \\ x_{n2} \end{bmatrix} f_{2} + \cdots + \begin{bmatrix} x_{1m} \\ x_{2m} \\ \vdots \\ x_{nm} \end{bmatrix} f_{m} + \begin{bmatrix} u_{1} \\ u_{2} \\ \vdots \\ u_{n} \end{bmatrix} $ where $r_{i}$ is the excess return of stock $i$, $x_{ij}$ is the exposure of stock $i$ to factor $j$, and $f_{j}$ is the return of factor $j$[46] 2. Select effective single factors, such as volatility, short-selling intention, and liquidity, based on theoretical direction and empirical validation[48] 3. Construct a multi-factor portfolio by combining these factors and optimizing weights[47] 2. Factor Name: Negative Enhancement - **Factor Construction Idea**: Underweight stocks expected to underperform or incur losses, leveraging negative factors or events to generate stable excess returns[56] - **Factor Construction Process**: 1. Identify stocks with negative attributes, such as analyst downgrades, equity pledges, or poor earnings reports 2. Underweight these stocks in the portfolio to reduce potential losses and achieve alpha[56] 3. Factor Name: Machine Learning-Based Alpha - **Factor Construction Idea**: Use deep learning models like TCN (Temporal Convolutional Networks) to extract complex and effective alpha factors from price and volume data[52] - **Factor Construction Process**: 1. Train neural networks on historical price and volume data to identify patterns and relationships 2. Generate alpha factors that outperform traditional genetic programming methods in terms of depth and complexity[51][52] --- Factor Backtesting Results 1. Quantitative Multi-Factor - **Excess Return**: Stable across long-term horizons - **Key Factors**: Volatility, short-selling intention, liquidity, and local pricing[48] 2. Negative Enhancement - **Excess Return**: Achieved through underweighting stocks with negative attributes or events[56] 3. Machine Learning-Based Alpha - **Performance**: Demonstrated superior results compared to traditional factor generation methods[52] --- Index Enhancement Methods 1. IPO Enhancement - **Annualized Return**: 2.13% in 2025 - **Segment Performance**: Sci-Tech Innovation Board (4.34%), ChiNext (2.52%)[67][68] 2. Stock Index Futures - **Annualized Basis Spread**: - CSI 300: -6.75% - SSE 50: -2.48% - CSI 500: -13.60% - CSI 1000: -18.09%[72][73] 3. Block Trades - **Median Discount Rate**: 5.38% (2017-2025), 8.23% in 2025[74][75] 4. Private Placements - **Median Discount Rate**: 14.55% (2017-2025), 11.87% in 2025[77]
