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**: Beta Factor **Construction Idea**: Capture the sensitivity of individual stock returns to market returns[14][15] **Construction Process**: - Calculate the regression coefficient of individual stock daily returns against the market index (CSI All Share Index) over the past 252 trading days using a half-life weighting of 63 days **Formula**: $ \text{Beta} = \text{Regression Coefficient} $ **Evaluation**: Reflects market risk sensitivity, useful for identifying high-risk or low-risk stocks[14][15] - **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 - Divide the regression slope by the average revenue to calculate growth rate **Formula**: $ \text{SGRO} = \frac{\text{Regression Slope}}{\text{Average Revenue}} $ **Evaluation**: Useful for identifying companies with strong growth trajectories[14][15] Factor Backtesting Results -

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**: Three-Month Reversal **Factor Construction Idea**: Measures the reversal effect by calculating the return over the past 60 trading days, assuming stocks with recent underperformance may outperform in the future [17]. **Factor Construction Process**: $ \text{Three-Month Reversal} = \text{Cumulative Return over the Past 60 Trading Days} $ **Factor Evaluation**: Demonstrates strong performance in certain index spaces, such as CSI 1000 and CSI A500, but underperforms in others like CSI 500 [17][22][25]. - **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]. - CSI 1000: Weekly excess return 1.09%, monthly excess return 1.40%, YTD excess return 0.38% [23]. - CSI A500: Weekly excess return 1.08%, monthly excess return 0.36%, YTD excess return 3.64% [25]. - **One-Year Momentum**: - CSI 300: Weekly excess return 0.46%, monthly excess return 0.36%, YTD excess return -1.85% [19]. - CSI 500: Weekly excess return 1.26%, monthly excess return 1.18%, YTD excess return 2.77% [21]. - CSI 1000: Weekly excess return 1.45%, monthly excess return 1.73%, YTD excess return 0.26% [23]. - CSI A500: Weekly excess return 0.74%, monthly excess return 0.87%, YTD excess return -2.03% [25]. - **SUE**: - CSI 300: Weekly excess return 0.51%, monthly excess return 2.15%, YTD excess return 3.03% [19]. - CSI 500: Weekly excess return -0.41%, monthly excess return 0.13%, YTD excess return 2.86% [21]. - CSI 1000: Weekly excess return -0.08%, monthly excess return 2.77%, YTD excess return 4.41% [23]. - CSI A500: Weekly excess return 0.47%, monthly excess return 1.63%, YTD excess return 2.04% [25]. - **Delta ROE (DELTAROE)**: - CSI 300: Weekly excess return 0.26%, monthly excess return 2.27%, YTD excess return 5.32% [19]. - CSI 500: Weekly excess return 0.58%, monthly excess return 2.49%, YTD excess return 4.03% [21]. - CSI 1000: Weekly excess return -1.15%, monthly excess return 0.74%, YTD excess return 3.01% [23]. - CSI A500: Weekly excess return 0.52%, monthly excess return 2.82%, YTD excess return 5.13% [25].

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].
