Quantitative Models and Construction Methods - Model Name: Maximized Factor Exposure Portfolio (MFE) Construction Idea: The MFE portfolio is designed to maximize single-factor exposure while controlling for various real-world constraints such as industry exposure, style exposure, stock weight deviation, and turnover rate. This approach ensures the factor's predictive effectiveness under practical constraints [40][41][42] 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, $f^{T}w$ is the weighted exposure of the portfolio to the factor, and $w$ is the stock weight vector to be solved [41] - Constraints: - Style Exposure: $X$ is the factor exposure matrix for stocks, $w_b$ is the benchmark weight vector, and $s_l$, $s_h$ are the lower and upper bounds for style factor exposure [41] - Industry Exposure: $H$ is the industry exposure matrix, where $H_{ij}=1$ if stock $i$ belongs to industry $j$, otherwise $H_{ij}=0$. $h_l$, $h_h$ are the lower and upper bounds for industry deviation [41] - Stock Weight Deviation: $w_l$, $w_h$ are the lower and upper bounds for stock weight deviation relative to the benchmark [41] - Component Weight Control: $B_b$ is a 0-1 vector indicating whether a stock belongs to the benchmark index. $b_l$, $b_h$ are the lower and upper bounds for component weight control [41] - No Short Selling: Ensures non-negative weights and limits individual stock weights to $l$ [41] - Full Investment: Ensures the portfolio is fully invested with $\mathbf{1}^{T}w=1$ [42] Evaluation: This model effectively tests factor validity under real-world constraints, making it more applicable for practical portfolio construction [40][41][42] --- Quantitative Factors and Construction Methods - Factor Name: BP Construction Idea: Measures valuation by comparing net assets to market capitalization [17] Construction Process: Formula: $BP = \frac{\text{Net Assets}}{\text{Market Capitalization}}$ [17] Evaluation: BP is a widely used valuation factor, but its effectiveness varies across different sample spaces [17] - Factor Name: Single-Season EP Construction Idea: Evaluates profitability by comparing quarterly net profit to market capitalization [17] Construction Process: Formula: $EP = \frac{\text{Quarterly Net Profit}}{\text{Market Capitalization}}$ [17] Evaluation: This factor is useful for identifying undervalued stocks with strong quarterly performance [17] - Factor Name: Single-Season SP Construction Idea: Measures revenue efficiency by comparing quarterly revenue to market capitalization [17] Construction Process: Formula: $SP = \frac{\text{Quarterly Revenue}}{\text{Market Capitalization}}$ [17] Evaluation: SP is effective in identifying companies with high revenue relative to their market value [17] - Factor Name: EPTTM Construction Idea: Tracks profitability using trailing twelve-month net profit relative to market capitalization [17] Construction Process: Formula: $EPTTM = \frac{\text{TTM Net Profit}}{\text{Market Capitalization}}$ [17] Evaluation: EPTTM is a robust profitability factor, especially for long-term performance analysis [17] - Factor Name: SPTTM Construction Idea: Measures revenue efficiency using trailing twelve-month revenue relative to market capitalization [17] Construction Process: Formula: $SPTTM = \frac{\text{TTM Revenue}}{\text{Market Capitalization}}$ [17] Evaluation: SPTTM is useful for identifying companies with consistent revenue generation [17] --- Factor Backtesting Results 沪深 300 Sample Space -
