Quantitative Models and Construction Methods - **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 limits. This approach ensures that the factor's predictive power is tested under realistic portfolio constraints, making it more applicable in actual investment scenarios [39][40]. **Model Construction Process**: The MFE portfolio is constructed using the following optimization model: $ \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, and \( w \) is the stock weight vector. - **Constraints**: - **Style Exposure**: \( X \) is the factor exposure matrix, \( w_b \) is the benchmark weight vector, and \( s_l, s_h \) are the lower and upper bounds for style exposure. - **Industry Exposure**: \( H \) is the industry exposure matrix, and \( h_l, h_h \) are the lower and upper bounds for industry deviation. - **Stock Weight Deviation**: \( w_l, w_h \) are the lower and upper bounds for stock weight deviation. - **Component Weight Control**: \( B_b \) is a binary vector indicating benchmark components, and \( b_l, b_h \) are the lower and upper bounds for component weights. - **No Short Selling**: Ensures non-negative weights and limits individual stock weights. - **Full Investment**: Ensures the portfolio is fully invested (\( \mathbf{1}^{T}\ w=1 \)) [40][41]. **Model Evaluation**: The MFE portfolio effectively tests factor efficacy under realistic constraints, making it a robust tool for factor validation in enhanced index strategies [39][40]. --- Quantitative Factors and Construction Methods -

**Factor Name**: One-Year Momentum **Factor Construction Idea**: Captures the momentum effect by excluding the most recent month and calculating the cumulative return over the prior 11 months [17]. **Factor Construction Process**: $ \text{One-Year Momentum} = \text{Cumulative Return over the Past 11 Months (Excluding the Most Recent Month)} $ **Factor Evaluation**: Performs well in CSI 500 and CSI 1000 spaces but shows mixed results in other index spaces [17][21][23]. - **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**: $ \text{SUE} = \frac{\text{Actual Earnings} - \text{Expected Earnings}}{\text{Standard Deviation of Expected Earnings}} $ **Factor Evaluation**: Consistently performs well across multiple index spaces, indicating its robustness as a predictive factor [17][22][25]. - **Factor Name**: Delta ROE (DELTAROE) **Factor Construction Idea**: Measures the change in return on equity (ROE) compared to the same quarter in the previous year [17]. **Factor Construction Process**: $ \text{DELTAROE} = \text{Current Quarter ROE} - \text{ROE from the Same Quarter Last Year} $ **Factor Evaluation**: Demonstrates strong predictive power in CSI 500 and CSI A500 spaces, with moderate performance in other index spaces [17][21][25]. --- Factor Backtesting Results - **Three-Month Reversal**: - CSI 300: Weekly excess return 0.66%, monthly excess return 0.65%, YTD excess return 3.01% [19]. - CSI 500: Weekly excess return 0.79%, monthly excess return 1.17%, YTD excess return 4.07% [21]. -

Group 2: Market Drivers - The market's strength is attributed to supportive policies, with the A-share market remaining robust above 3000 points, leading to a preference for small-cap stocks over large-cap stocks [3]. - Continuous liquidity and a low-interest-rate environment favor small-cap stock speculation, while market volatility allows enhanced index products to capture excess returns [3][8]. - The top five sectors in the CSI 2000 index include Machinery Equipment (11.5%), Electronics (9.1%), Computers (7.8%), Pharmaceutical Biology (6.7%), and Basic Chemicals (6.7%) [3]. Group 3: Future Outlook - There is potential for further gains in small-cap stocks due to ongoing supportive policies and the early-stage growth of industries like AI and robotics [8]. - The market's volatility continues to provide opportunities for quantitative strategies to identify undervalued small-cap stocks, enhancing the performance of the 1000ETF Enhanced and CSI 2000 Enhanced ETF [8]. - Investors are advised to consider entry points during market pullbacks and maintain a long-term holding strategy to increase the probability of profitability [9].

Core Viewpoint - The surge in the establishment of index-enhanced funds indicates a shift in the public fund industry towards passive investment strategies, with 76 such funds launched in the first half of the year, surpassing the total for the entire previous year [1][3]. Group 1: Market Trends - The number of index-enhanced funds established in 2023 has reached 76 by June 20, compared to only 42 in the entirety of 2022 [3]. - The most popular benchmark for these funds is the CSI A500 index, with 41 funds utilizing it, alongside others focusing on the STAR Market Composite Index and the CSI 800 index [3]. - The rapid growth of index funds reflects an increasing acceptance in the market, driven by the poor performance of actively managed funds over the past two years [4]. Group 2: Performance Insights - The average excess return of index-enhanced funds across the market is 2.58%, with six funds outperforming their benchmarks by over 10 percentage points [1]. - Notable performers include the Chuangjin Hexin North Certificate 50 Enhanced A fund, which achieved a net value growth rate of 28.21% year-to-date [7]. - Small-cap style index-enhanced funds have shown particularly strong performance, with several funds exceeding a 15% increase in net value [8]. Group 3: Factors Driving Growth - The growth in index-enhanced funds is attributed to three main factors: the underperformance of actively managed funds, the introduction of attractive new indices, and regulatory encouragement for index-based investments [3]. - The competitive landscape has made it challenging for new entrants to compete directly on standard indices, making index-enhanced funds a viable alternative [4]. - The active engagement of leading fund sales platforms, such as Ant Fund, has further fueled the enthusiasm for index-enhanced fund offerings [5].
