Quantitative Models and Construction Methods Model Name: MFE (Maximized Factor Exposure) Portfolio - Model Construction Idea: The MFE portfolio aims to maximize the exposure to a single factor while controlling for various constraints such as industry exposure, style exposure, and individual stock weight deviations[40][41]. - Model Construction Process: - The optimization model is formulated as follows: $\begin{array}{ll} \text{max} & f^{T} w \\ \text{s.t.} & s_{l} \leq X(w - w_{b}) \leq s_{h} \\ & h_{l} \leq H(w - w_{b}) \leq h_{h} \\ & w_{l} \leq w - w_{b} \leq w_{h} \\ & b_{l} \leq B_{b} w \leq b_{h} \\ & \mathbf{0} \leq w \leq l \\ & \mathbf{1}^{T} w = 1 \end{array}$ - Explanation of Parameters: - $f$: Factor values - $w$: Stock weight vector - $X$: Factor exposure matrix for style factors - $w_{b}$: Benchmark index component weights - $s_{l}, s_{h}$: Lower and upper bounds for style factor exposure - $H$: Industry exposure matrix - $h_{l}, h_{h}$: Lower and upper bounds for industry exposure - $w_{l}, w_{h}$: Lower and upper bounds for individual stock weight deviations - $B_{b}$: 0-1 vector indicating whether a stock is a benchmark component - $b_{l}, b_{h}$: Lower and upper bounds for component stock weight - $l$: Upper limit for individual stock weight - The model aims to maximize the factor exposure while satisfying constraints on style, industry, and individual stock weights[40][41][42]. Factor Construction and Performance Factor Name: Standardized Unexpected Earnings (SUE) - Factor Construction Idea: Measures the deviation of actual earnings from expected earnings, standardized by the standard deviation of expected earnings[17]. - Factor Construction Process: - Formula: $\text{SUE} = \frac{\text{Actual Earnings} - \text{Expected Earnings}}{\text{Standard Deviation of Expected Earnings}}$ - Explanation: This factor captures the surprise in earnings relative to market expectations, which can indicate potential stock price movements[17]. Factor Name: DELTAROE - Factor Construction Idea: Measures the change in Return on Equity (ROE) from the same quarter of the previous year[17]. - Factor Construction Process: - Formula: $\text{DELTAROE} = \text{Current Quarter ROE} - \text{ROE of the Same Quarter Last Year}$ - Explanation: This factor indicates the improvement or deterioration in a company's profitability over time[17]. Factor Performance Monitoring Performance in Different Index Spaces - CSI 300 Index: - Recent week: Factors like Standardized Unexpected Earnings, Specificity, and Single Quarter EP performed well, while factors like 3-Month Earnings Revisions, 1-Month Turnover, and 1-Year Momentum performed poorly[1][18]. - Recent month: Factors like Single Quarter EP, Expected EPTTM, and EPTTM performed well, while factors like 1-Year Momentum, Illiquidity Shock, and 1-Month Turnover performed poorly[18]. - Year-to-date: Factors like Single Quarter Earnings Growth, Single Quarter Revenue Growth, and DELTAROE performed well, while factors like 1-Year Momentum, 1-Month Turnover, and 3-Month Turnover performed poorly[18]. - CSI 500 Index: - Recent week: Factors like Standardized Unexpected Earnings, Specificity, and SPTTM performed well, while factors like Single Quarter ROA, Single Quarter ROE, and 3-Month Institutional Coverage performed poorly[1][20]. - Recent month: Factors like DELTAROE, Single Quarter Earnings Growth, and Single Quarter Net Profit Growth performed well, while factors like 3-Month Institutional Coverage, 1-Month Turnover, and Illiquidity Shock performed poorly[20]. - Year-to-date: Factors like Single Quarter Revenue Growth, 1-Month Reversal, and Expected PEG performed well, while factors like EPTTM, 3-Month Volatility, and 1-Month Turnover performed poorly[20]. - CSI 1000 Index: - Recent week: Factors like DELTAROE, Single Quarter Earnings Growth, and DELTAROA performed well, while factors like Expected EPTTM, 3-Month Institutional Coverage, and 3-Month Turnover performed poorly[1][22]. - Recent month: Factors like Standardized Unexpected Earnings, BP, and Single Quarter Net Profit Growth performed well, while factors like Illiquidity Shock, 3-Month Institutional Coverage, and 3-Month Turnover performed poorly[22]. - Year-to-date: Factors like Standardized Unexpected Earnings, Standardized Unexpected Revenue, and Illiquidity Shock performed well, while factors like 3-Month Volatility, 1-Month Volatility, and Single Quarter ROE performed poorly[22]. - CSI A500 Index: - Recent week: Factors like Specificity, Expected EPTTM, and Single Quarter Earnings Growth performed well, while factors like 3-Month Earnings Revisions, 1-Month Turnover, and 3-Month Turnover performed poorly[1][24]. - Recent month: Factors like Expected EPTTM, Single Quarter Earnings Growth, and Single Quarter EP performed well, while factors like 1-Month Turnover, 3-Month Turnover, and Illiquidity Shock performed poorly[24]. - Year-to-date: Factors like Expected PEG, Single Quarter Earnings Growth, and DELTAROE performed well, while factors like 1-Year Momentum, 1-Month Turnover, and SPTTM performed poorly[24]. - Public Fund Heavyweight Index: - Recent week: Factors like Specificity, DELTAROE, and DELTAROA performed well, while factors like 3-Month Earnings Revisions, 3-Month Turnover, and 1-Month Turnover performed poorly[1][26]. - Recent month: Factors like Expected EPTTM, Single Quarter Earnings Growth, and Single Quarter EP performed well, while factors like Illiquidity Shock, 1-Year Momentum, and 3-Month Institutional Coverage performed poorly[26]. - Year-to-date: Factors like DELTAROA, DELTAROE, and Standardized Unexpected Earnings performed well, while factors like 1-Month Volatility, BP, and Expected BP performed poorly[26].
