Quantitative Models and Construction Methods - **Model Name**: Maximized Factor Exposure Portfolio (MFE) **Model Construction Idea**: The model aims to maximize single-factor exposure while controlling for various constraints such as industry exposure, style exposure, stock weight deviation, and turnover rate. This approach tests the effectiveness of factors under real-world constraints, ensuring their predictive power in portfolio construction [39][40][41] **Model Construction Process**: The optimization model is formulated 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} $ - **Objective Function**: Maximize single-factor exposure, where $f$ represents factor values, and $f^{T}w$ is the weighted exposure of the portfolio to the factor. $w$ is the stock weight vector to be optimized. - **Constraints**: - **Style Exposure**: $X$ is the matrix of stock exposures to style factors, $w_b$ is the benchmark weight vector, and $s_l$, $s_h$ are the lower and upper bounds for style factor exposure deviation. - **Industry Exposure**: $H$ is the industry exposure matrix, $h_l$, $h_h$ are the lower and upper bounds for industry deviation. - **Stock Weight Deviation**: $w_l$, $w_h$ are the lower and upper bounds for individual stock weight deviation. - **Component Weight Control**: $B_b$ is a binary vector indicating whether a stock belongs to the benchmark index, $b_l$, $b_h$ are the lower and upper bounds for component stock weight. - **No Short Selling**: Ensures non-negative weights and limits individual stock weights. - **Full Investment**: Ensures the portfolio is fully invested with weights summing to 1 [39][40][41] **Model Evaluation**: The model effectively tests factor validity under real-world constraints, ensuring factors contribute to portfolio returns in practical scenarios [39][40][41] Factor Construction and Methods - **Factor Name**: Standardized Unexpected Earnings (SUE) **Factor Construction Idea**: Measures the deviation of actual quarterly net profit from expected net profit, standardized by the standard deviation of expected net profit [17] **Factor Construction Process**: $ SUE = \frac{\text{Actual Quarterly Net Profit} - \text{Expected Net Profit}}{\text{Standard Deviation of Expected Net Profit}} $ **Factor Evaluation**: Useful for identifying stocks with earnings surprises, which may lead to price adjustments [17] - **Factor Name**: One-Month Reversal **Factor Construction Idea**: Captures short-term price reversal by measuring the return over the past 20 trading days [17] **Factor Construction Process**: $ \text{One-Month Reversal} = \text{Return over the past 20 trading days} $ **Factor Evaluation**: Effective in detecting short-term mean-reverting behavior in stock prices [17] - **Factor Name**: Delta ROA **Factor Construction Idea**: Measures the change in return on assets (ROA) compared to the same quarter of the previous year [17] **Factor Construction Process**: $ \Delta ROA = \text{Current Quarter ROA} - \text{ROA of the Same Quarter Last Year} $ **Factor Evaluation**: Indicates improvement or deterioration in asset efficiency, which can signal fundamental changes [17] Factor Backtesting Results **Performance in CSI 300 Sample Space** -
