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. Trend Factor - **Recent Weekly Return**: 2.39% - **Recent Monthly Return**: 5.57% - **Year-to-Date Return**: -0.70% - **Annualized Return (1 Year)**: 24.36% - **Annualized Return (10 Years)**: 14.25%[11][13] 2. Volatility Factor - **Recent Weekly Return**: -1.75% - **Recent Monthly Return**: -3.95% - **Year-to-Date Return**: 4.10% - **Annualized Return (1 Year)**: 24.26% - **Annualized Return (10 Years)**: -13.16%[11][13] 3. BP Factor - **Recent Weekly Return**: 0.68% - **Recent Monthly Return**: 0.06% - **Year-to-Date Return**: -4.33% - **Annualized Return (1 Year)**: -1.51% - **Annualized Return (10 Years)**: -0.61%[42][43] 4. Three-Month Institutional Coverage Factor - **Recent Weekly Return**: 1.70% - **Recent Monthly Return**: 1.29% - **Year-to-Date Return**: 4.96% - **Annualized Return (1 Year)**: 1.66% - **Annualized Return (10 Years)**: 4.39%[46][48]

- The report uses the Mahalanobis distance of weekly price and trading volume changes to measure industry crowding levels[3][17] - The construction process involves identifying industries in the first quadrant (price and volume both rising) and the third quadrant (price and volume both falling) and marking points outside the ellipse as industries with significant short-term deviations at a 99% confidence level[17] - The building materials industry experienced short-term trading overselling last week[3][18]

Core Viewpoints - The current macroeconomic environment is generally favorable for equity, bond, industrial products, and gold assets, while the technical analysis indicates a downward trend for equity, bond, and industrial products, and an upward trend for gold assets [1][3][21]. Macroeconomic Perspective - The analysis categorizes macroeconomic indicators into upward and downward trends, assessing their impact on asset returns. A significant difference in average returns is noted based on the trend direction of these indicators [3][4]. - The macroeconomic indicators suggest a positive outlook for equity, bond, industrial products, and gold assets [5][6]. Technical Perspective - The trend indicators for various asset classes show that as of March 31, 2025, equity, bond, and industrial products are trending downwards, while gold is trending upwards [10][11]. - The equity asset valuation is currently low, with a historical 5-year ERP percentile of 78.36% [14][15]. Asset Flow Indicators - As of February 2025, the equity asset's net inflow is 462 billion, indicating a state of capital inflow [17][18]. Summary of Views - The combined scores from macro and technical analyses indicate a bullish outlook for equity and gold, a neutral stance for industrial products, and a bullish view for bonds [19][21]. Asset Allocation Performance Tracking - Historical performance data shows that the fixed ratio combined with macro and technical indicators yielded a return of 1.20% in March 2025, with an annualized return of 11.92% since March 2006 [2][27]. - The volatility-controlled and risk-parity combinations yielded returns of 1.72% and 1.18%, respectively, with annualized returns of 9.33% and 9.66% since March 2006 [28].
