Core Viewpoint - The rapid growth of index-enhanced funds in the market is driven by the evolution of market conditions and the increasing demand from investors for more sophisticated investment tools, with a total scale exceeding 200 billion yuan by the end of Q1 2025, representing an increase of over 80% since the end of 2020 [1]. Group 1: Definition and Characteristics of Quantitative Index Enhancement - Quantitative index enhancement involves tracking benchmark indices while using quantitative models to optimize stock selection and portfolio management to pursue excess returns (Alpha) [1]. - Unlike traditional index funds that passively replicate constituent stocks, index-enhanced products allow fund managers to adjust holdings within certain constraints to achieve returns that exceed the index [1]. - The average return of index-enhanced funds based on the CSI 300 index was 25.48%, compared to 6.07% for ordinary CSI 300 index funds, indicating the effectiveness of the index enhancement strategy [5]. Group 2: Performance Comparison - Over the past decade, the index-enhanced fund index has shown significant excess returns, with a gain of 24.88% compared to -18.05% for the CSI 300 index and 2.26% for stock index funds [2][3]. - The performance of index-enhanced products is particularly notable during periods of market recovery, as they benefit from both beta returns from the underlying index and alpha returns from active management strategies [7]. Group 3: Mechanisms of Index Enhancement - The enhancement is achieved through two core components: modeling stock returns and optimizing the portfolio relative to the benchmark index [8]. - Three primary methods for achieving index enhancement include: 1. Multi-factor stock selection models that assess various factors such as value, momentum, growth, sentiment, and quality to improve stock selection accuracy [10]. 2. AI stock selection techniques that utilize machine learning and deep learning to uncover patterns in historical data and enhance stock selection efficiency [11][12]. 3. Fundamental enhancement strategies that analyze a company's financial health and operational efficiency to identify investment opportunities [13]. Group 4: Key Indicators for Index Enhanced Funds - When selecting index-enhanced funds, important indicators to consider include annualized excess returns, tracking error, information ratio, maximum drawdown, daily and monthly win rates, all centered around the core metric of daily excess returns [13].

Multi-factor stock selection models that assess various factors such as value, momentum, and quality [10] 2. AI stock selection techniques that utilize machine learning and deep learning to identify patterns in historical data [11] 3. Fundamental enhancement strategies that analyze a company's financial health to optimize the investment portfolio [12] Group 5: Key Indicators for Selection - When selecting index-enhanced funds, important indicators to consider include annualized excess returns, tracking error, information ratio, maximum drawdown, and win rates [13]
