Quantitative Models and Construction Methods 1. Model Name: Maximized Factor Exposure Portfolio (MFE) - Model Construction Idea: The MFE portfolio is designed to maximize the exposure of a single factor while controlling for various constraints such as industry exposure, style exposure, stock weight deviation, and turnover rate[64][65] - Model Construction Process: - The optimization model is formulated as follows: $\begin{array}{ll} \max & f^{T}w \\ \text{s.t.} & s_{l} \leq X(w-w_{b}) \leq s_{h} \\ & h_{l} \leq H(w-w_{b}) \leq h_{h} \\ & w_{l} \leq w-w_{b} \leq w_{h} \\ & b_{l} \leq B_{b}w \leq b_{h} \\ & 0 \leq w \leq l \\ & 1^{T}w = 1 \\ & \Sigma|w-w_{0}| \leq to_{h} \end{array}$ - Explanation of Parameters: - $f^{T}w$: Weighted exposure of the portfolio to the factor - $w$: Portfolio weight vector - $w_{b}$: Benchmark weight vector - $X, H, B_{b}$: Matrices representing factor, industry, and benchmark exposures - $s_{l}, s_{h}, h_{l}, h_{h}, w_{l}, w_{h}, b_{l}, b_{h}, to_{h}$: Constraints on factor exposure, industry exposure, stock weight deviation, and turnover rate - Constraints include: - Limiting style and industry deviations relative to the benchmark - Controlling stock weight deviations and turnover rates - Ensuring full investment (weights sum to 1) and no short selling[64][65][67] - The portfolio is rebalanced monthly, and historical returns are calculated after deducting transaction costs to evaluate factor effectiveness[68] - Model Evaluation: The MFE model effectively isolates the impact of individual factors while adhering to practical constraints, making it a robust tool for factor evaluation[64][65] --- Quantitative Factors and Construction Methods 1. Factor Name: Trend - Factor Construction Idea: Captures the momentum of stock price trends over different time horizons[16] - Factor Construction Process: - Two variations: - Trend_120: $\text{EWMA}(\text{halflife}=20) / \text{EWMA}(\text{halflife}=120)$ - Trend_240: $\text{EWMA}(\text{halflife}=20) / \text{EWMA}(\text{halflife}=240)$ - $\text{EWMA}$: Exponentially Weighted Moving Average[16] - Factor Evaluation: Demonstrates strong performance in capturing price continuation patterns, particularly in volatile markets[11][13] 2. Factor Name: Volatility - Factor Construction Idea: Measures the variability of stock returns over a specified period[16] - Factor Construction Process: - Variants include: - Stdvol: Standard deviation of daily returns over the past 243 days - Ivff: Fama-French 3-factor idiosyncratic volatility over the past 243 days - Range: $\text{High Price}/\text{Low Price} - 1$ over the past 243 days - MaxRet_6: Average of the six highest daily returns over the past 243 days - MinRet_6: Average of the six lowest daily returns over the past 243 days[16] - Factor Evaluation: Effective in identifying high-risk stocks, though performance may vary across market conditions[11][13] 3. Factor Name: BP (Book-to-Price Ratio) - Factor Construction Idea: Represents the valuation of a stock relative to its book value[20] - Factor Construction Process: - Formula: $\text{BP} = \text{Net Assets} / \text{Market Capitalization}$[20] - Factor Evaluation: Consistently performs well in value-oriented strategies, particularly in markets favoring undervalued stocks[42][43] 4. Factor Name: Three-Month Institutional Coverage - Factor Construction Idea: Measures the level of analyst coverage over the past three months[20] - Factor Construction Process: - Formula: Count of research reports published by institutions over the past three months[20] - Factor Evaluation: Strongly correlated with market sentiment and stock visibility, often leading to positive price momentum[8][46] --- Factor Backtesting Results 1.
