- The report tracks the performance of Guosen Financial Engineering's index enhancement portfolios, which are constructed based on multi-factor stock selection models targeting benchmarks such as CSI 300, CSI 500, CSI 1000, and CSI A500 indices. The goal is to consistently outperform the respective benchmarks [11][12][14] - The construction process of the index enhancement portfolios includes three main components: return prediction, risk control, and portfolio optimization. The optimization model maximizes single-factor exposure while controlling for constraints such as industry exposure, style exposure, stock weight deviation, turnover rate, and component stock weight ratio [12][41][42] - The Maximized Factor Exposure (MFE) portfolio is used to test the effectiveness of individual factors under real-world constraints. The optimization model is expressed as follows: $\begin{array}{ll}max&f^{T}\ w\\ s.t.&s_{l}\leq X(w-w_{b})\leq s_{h}\\ &h_{l}\leq H(w-w_{b})\leq h_{h}\\ &w_{l}\leq w-w_{b}\leq w_{h}\\ &b_{l}\leq B_{b}w\leq b_{h}\\ &\mathbf{0}\leq w\leq l\\ &\mathbf{1}^{T}\ w=1\end{array}$ where \(f\) represents factor values, \(w\) is the stock weight vector, and constraints include style exposure (\(X\)), industry exposure (\(H\)), stock weight deviation (\(w_b\)), and component stock weight ratio (\(B_b\)) [41][42][43] - The report monitors the performance of common stock selection factors across different sample spaces, including CSI 300, CSI 500, CSI 1000, CSI A500, and public fund heavy-holding indices. Factors are tested using MFE portfolios to evaluate their excess return relative to benchmarks [11][15][18] - The factor library includes over 30 factors categorized into valuation, reversal, growth, profitability, liquidity, volatility, corporate governance, and analyst-related factors. Examples include BP (Book-to-Price), EPTTM (Earnings-to-Price TTM), one-month reversal, three-month reversal, one-year momentum, and others [16][17] - The report highlights the performance of specific factors in different sample spaces: - **CSI 300**: One-month reversal, three-month reversal, and EPTTM one-year percentile performed well recently, while three-month institutional coverage and standardized unexpected earnings performed poorly [1][18] - **CSI 500**: Three-month volatility, three-month reversal, and EPTTM one-year percentile performed well recently, while one-year momentum and standardized unexpected revenue performed poorly [1][20] - **CSI 1000**: One-month volatility, one-month turnover, and three-month reversal performed well recently, while executive compensation and three-month earnings revisions performed poorly [1][22] - **CSI A500**: One-month reversal, EPTTM one-year percentile, and one-month volatility performed well recently, while three-month institutional coverage and one-year momentum performed poorly [1][24] - **Public fund heavy-holding index**: Dividend yield, three-month reversal, and EPTTM performed well recently, while standardized unexpected revenue and three-month earnings revisions performed poorly [1][26][27] - The report tracks the excess returns of public fund index enhancement products, including CSI 300, CSI 500, CSI 1000, and CSI A500.

Quantitative Models and Construction Methods 1. Model Name: Maximized Factor Exposure Portfolio (MFE) - **Model Construction Idea**: The MFE portfolio is designed to test the effectiveness of individual factors under real-world constraints, such as controlling for industry exposure, style exposure, stock weight limits, and turnover rates. The goal is to maximize the exposure of a single factor while adhering to these constraints[39][40] - **Model Construction Process**: - The objective function is to maximize single-factor exposure, where $f$ represents the factor values, $f^T w$ is the weighted exposure of the portfolio to the single factor, and $w$ is the vector of stock weights - The optimization model is as follows: $$ \begin{array}{ll} max & f^{T} w \\ s.t. & s_{l} \leq X(w-w_{b}) \leq s_{h} \\ & h_{l} \leq H(w-w_{b}) \leq h_{h} \\ & w_{l} \leq w-w_{b} \leq w_{h} \\ & b_{l} \leq B_{b}w \leq b_{h} \\ & \mathbf{0} \leq w \leq l \\ & \mathbf{1}^{T} w = 1 \end{array} $$ - The first constraint limits the portfolio's style exposure relative to the benchmark index, where $X$ is the factor exposure matrix, $w_b$ is the weight vector of the benchmark index constituents, and $s_l$ and $s_h$ are the lower and upper bounds of style factor exposure, respectively - The second constraint limits the portfolio's industry deviation, where $H$ is the industry exposure matrix, and $h_l$ and $h_h$ are the lower and upper bounds of industry deviation, respectively - The third constraint limits individual stock deviations relative to the benchmark index constituents, where $w_l$ and $w_h$ are the lower and upper bounds of individual stock deviations - The fourth constraint limits the weight proportion of the portfolio within the benchmark index constituents, where $B_b$ is a 0-1 vector indicating whether a stock belongs to the benchmark index, and $b_l$ and $b_h$ are the lower and upper bounds of the weight proportion - The fifth constraint prohibits short selling and limits the upper bound of individual stock weights - The sixth constraint ensures that the portfolio is fully invested, with the sum of weights equal to 1[39][40][41] - The MFE portfolio is constructed for a given benchmark index by applying the above optimization model. To avoid excessive concentration, the deviation of individual stock weights relative to the benchmark is typically set between 0.5% and 1%[41][43] - **Model Evaluation**: The MFE portfolio is used to evaluate the effectiveness of individual factors under realistic constraints, ensuring that the selected factors can contribute to the actual return prediction in the final portfolio[39][40] --- Model Backtesting Results 1.
