Quantitative Models and Construction Methods Model Name: Momentum Model - Construction Idea: The momentum model is designed to capture the trend-following behavior in the market, particularly effective during the end-of-quarter period when funds tend to adjust their positions based on recent performance trends [13][37] - Detailed Construction Process: The model identifies stocks with strong recent performance and allocates more weight to them. The formula used is: $ \text{Momentum Score} = \frac{\text{Price}_{t} - \text{Price}_{t-1}}{\text{Price}_{t-1}} $ where $\text{Price}_{t}$ represents the current price and $\text{Price}_{t-1}$ represents the price at the previous time period [13][37] - Evaluation: The momentum model performs well during the end-of-quarter period, aligning with the characteristic fund allocation behavior [13][37] Model Backtesting Results Momentum Model - Information Ratio (IR): 1.75 [38] - Excess Return: 1.95% [38] Quantitative Factors and Construction Methods Factor Name: Value Factor - Construction Idea: The value factor aims to identify undervalued stocks by comparing their market price to fundamental metrics such as earnings, book value, and cash flow [13][29] - Detailed Construction Process: The factor is constructed using the following formula: $ \text{Value Score} = \frac{\text{Earnings}}{\text{Price}} + \frac{\text{Book Value}}{\text{Price}} + \frac{\text{Cash Flow}}{\text{Price}} $ where $\text{Earnings}$, $\text{Book Value}$, and $\text{Cash Flow}$ are fundamental metrics, and $\text{Price}$ is the current market price [13][29] - Evaluation: The value factor has shown a significant shift in fund allocation from growth to value stocks since April, indicating its effectiveness in capturing the market's structural adjustments [29][33] Factor Backtesting Results Value Factor - Information Ratio (IR): 1.38 [38] - Excess Return: 1.45% [38]

Quantitative Models and Construction Methods - **Model Name**: Neutral Constraint Maximum Factor Exposure Portfolio **Construction Idea**: Maximize the exposure of the target factor in the portfolio while maintaining neutrality in industry and style exposures relative to the benchmark index[60][61][63] **Construction Process**: 1. **Objective Function**: Maximize portfolio exposure to the target factor $ \text{Max}\quad w^{\prime}X_{\text{target}} $ 2. **Constraints**: - Industry neutrality: $ (w - w_b)^{\prime}X_{\text{inad}} = 0 $ - Style neutrality: $ (w - w_b)^{\prime}X_{\text{Beta}} = 0 $ - Weight deviation limit: $ |w - w_b| \leq 1\% $ - No short selling: $ w \geq 0 $ - Full allocation: $ w^{\prime}1 = 1 $ - Constituents from benchmark index: $ w^{\prime}B = 1 $ **Evaluation**: The model ensures that the portfolio remains neutral to industry and style biases while maximizing factor exposure[60][61][63] Factor Construction and Definitions -

**Factor Name**: Book-to-Price (BP) **Construction Idea**: Measure valuation by comparing book equity to market capitalization[14][15] **Construction Process**: - $ \text{BP} = \frac{\text{Shareholders' Equity}}{\text{Market Capitalization}} $ **Evaluation**: Indicates undervaluation or overvaluation of stocks, commonly used in value investing[14][15] - **Factor Name**: Sales Growth (SGRO) **Construction Idea**: Assess growth potential by analyzing historical revenue trends[14][15] **Construction Process**: - Perform regression on annual revenue data from the past five fiscal years -

Market Overview - The Shanghai Composite Index rose by 1.04% and the ChiNext Index increased by 3.11% on June 25, 2025, with sectors like comprehensive finance, non-bank finance, and defense industry leading the gains at 5.7%, 4.4%, and 3.49% respectively, while oil and petrochemicals, coal, and transportation sectors lagged behind with changes of -0.15%, -0.04%, and 0.25% [1] Reasons for Market Fluctuation - The market experienced a significant increase in volume, with brokerage, computer, and military sectors showing the highest gains, contributing to the Shanghai Composite Index reaching a new high for the year. Recent improvements in the international market environment, including dovish signals from the Federal Reserve and a potential ceasefire agreement between Israel and Iran, have positively influenced global risk assets. Additionally, the domestic economic fundamentals are improving, supported by steady capital market reforms [2] Future Market Outlook - The outlook for the second half of the year remains moderately optimistic, driven by ongoing growth stabilization policies, accelerated infrastructure investment, and effective consumption stimulus measures. Industrial profits are expected to recover in the latter half of the year. Capital market reforms, such as relaxing insurance capital market entry ratios and optimizing dividend repurchase systems, are set to enhance the A-share market ecosystem. The strong policy intent to stabilize the capital market suggests limited chances for significant market corrections. Two asset categories are highlighted: high-elasticity new productivity sectors, including new technologies and materials, and stable industries focusing on core operations and shareholder returns, which are less affected by economic downturns in developed economies [3] Factors to Monitor - Key factors to watch include geopolitical situations, upcoming US-China trade negotiations in early August, EU-US trade talks in early July, and marginal changes in domestic real estate sales data [4]
