1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - The report comprehensively analyzes public and private quantitative funds, covering aspects such as the basic characteristics of quantitative strategies, the development history of domestic quantitative investment, the current development status of the industry, the operational characteristics and performance of quantitative funds, the differences in investment operations between public and private quantitative funds, and how to select quantitative products [1][2][3]. - Quantitative strategies are based on historical data, using methods such as data mining and mathematical modeling to discover investment opportunities, with strong systematic and disciplined features. They focus on research breadth to achieve probability - based wins, different from subjective strategies that rely on research depth [10][11][12]. - Public and private quantitative funds have different development paths and characteristics. Public quantitative funds have experienced stages of growth, slowdown, and strategy diversification, while private quantitative funds have gone through explosive growth, stable development, and challenges [5][16][19]. - There are significant differences in regulatory requirements, management behaviors, investment strategies, and fee terms between public and private quantitative funds, which lead to differences in their risk - return characteristics [6]. - When selecting quantitative products, investors should use a four - dimensional evaluation system of "strategy deconstruction - positioning matching - indicator verification - ability evaluation" to consider factors such as strategy environment adaptability, risk - return characteristic persistence, and management team moat depth [6][90]. 3. Summary According to the Directory 3.1 Quantitative Strategy Basic Characteristics - Quantitative strategies use historical data to discover price change patterns and formulate investment strategies. The most widely used quantitative stock - selection model is the multi - factor model, including price - volume factors, fundamental factors, and alternative factors. Some funds also introduce machine learning factors [10]. - Quantitative strategies have strong strategy discipline, systematically mining investment opportunities and avoiding the influence of subjective emotions. Their risk - control systems are embedded in strategies, with different constraints for different types of products [11]. - Compared with subjective investment, quantitative investment focuses on research breadth and probability - based wins, with lower marginal costs and a wider range of tracked investment opportunities [12]. 3.2 Domestic Quantitative Investment Development History 3.2.1 Public Fund Quantitative Investment Development History - **Germination Period (2004 - 2014)**: From the exploration of "subjective + quantitative" to the initial application of the multi - factor model. The first index - enhanced fund and active quantitative stock - selection fund were established, and with the return of talents, the multi - factor stock - selection model was gradually applied [12][13][15]. - **Accelerated Growth Period (2015 - 2021)**: The multi - factor model became popular, and the scale of quantitative funds expanded rapidly. The scale of index - enhanced strategies increased significantly, while the scale of hedge strategies grew rapidly from 2020 and then declined [16]. - **Steady Development Period (2022 - present)**: The growth rate of the overall scale of public quantitative funds has slowed down, but strategies have become more diversified. Different product lines complement each other, and some managers introduce AI algorithms to iterate strategies [19]. 3.2.2 Private Fund Quantitative Investment Development History - Private quantitative funds have experienced three rounds of growth. From 2019 to 2021, there was explosive growth, with the scale reaching 1.08 trillion yuan at the end of 2021, accounting for 17.1% of the total scale of private securities investment funds. From 2021 to 2023, there was steady development, and in 2024, the industry faced challenges due to market fluctuations and stricter regulations. In 2025, private fund filings recovered [5][22][25]. 3.3 Public and Private Quantitative Fund Industry Development Status 3.3.1 Public Fund Quantitative Strategy and Pattern Distribution - **Strategy Classification**: Public quantitative strategies mainly include active quantitative strategies, index - enhanced strategies, and quantitative hedge strategies. Some equity parts of fixed - income + funds also use quantitative management methods [31]. - **Scale Distribution**: As of 2025Q1, the number of public quantitative equity funds reached 654, with a scale of 3025.88 billion yuan. Index - enhanced products had the largest scale, and the management scale concentration of the top ten managers was relatively high [32][37]. 3.3.2 Private Fund Quantitative Strategy and Manager Situation - **Strategy Classification**: Private quantitative investment strategies are more diverse, including quantitative long - only, stock neutral, convertible bond strategies, CTA strategies, other derivative strategies, arbitrage strategies, and composite strategies [38]. - **Hundred - Billion Private Quantitative Managers**: As of the end of June 2025, there were 39 hundred - billion private quantitative investment fund managers, accounting for nearly half of the total number of hundred - billion private funds [5]. 3.4 Operational Characteristics and Performance of Public and Private Stock Quantitative Funds 3.4.1 Operational Characteristics - **High Turnover**: Quantitative funds have a relatively high turnover rate, which helps capture short - term trading opportunities. Public quantitative funds' annual bilateral turnover is mainly between 2 - 20 times, and private quantitative funds' turnover is generally above 30 times [47][48]. - **Large Number of Holdings**: Quantitative funds usually hold a large number of stocks, with a high degree of diversification in stocks and industries. Public quantitative funds' holding numbers are mainly between 50 - 600, and some exceed 2000. They can reduce non - systematic risks [53][54]. 3.4.2 Performance - **Index - Enhanced Products**: The absolute and excess returns of index - enhanced products vary from year to year, with the overall excess - acquisition ability of CSI 1000 index - enhanced > CSI 500 index - enhanced > SSE 500 index - enhanced. Private index - enhanced funds generally have better excess returns than public ones, but with greater differentiation [57][58]. - **Active Quantitative Funds**: The performance of public and private active quantitative funds varies by year. In 2019 - 2020, public active quantitative funds performed better, while in 2018, 2021 - 2023, private ones performed better. Private funds have greater performance and drawdown differentiation [66]. - **Quantitative Hedge Funds**: Private quantitative hedge funds generally outperform public ones in terms of annual returns, but their performance and drawdown differentiation are also greater [70]. 3.5 Differences in Investment Operations between Public and Private Quantitative Funds - **Regulatory Requirements and Contracts**: Public quantitative funds are regulated by the "Securities Investment Fund Law", with high regulatory intensity and high information transparency. Private quantitative funds are regulated by the "Regulations on the Supervision and Administration of Private Investment Funds", with more customized contracts and higher risk levels [79]. - **Management Behaviors**: Public quantitative managers rely on institutionalized teams and standardized IT infrastructure, with a focus on systematic risk control and compliance. Private managers use an elite - based organizational structure, with higher hardware investment and employee incentives, and their product strategies may be more differentiated [81]. - **Investment Strategies and Restrictions**: Public quantitative funds have stricter constraints on investment scope, proportion, and tracking error, with lower turnover. Private quantitative funds have more flexible mechanisms, with higher turnover and greater elasticity in excess returns [6][84]. - **Fee Terms**: Private quantitative product fee terms are more complex, usually including management fees and performance rewards, while public quantitative products mainly charge fixed management fees and custody fees [6][87]. 3.6 How to Select Quantitative Products - When selecting quantitative products, investors should use a four - dimensional evaluation system of "strategy deconstruction - positioning matching - indicator verification - ability evaluation" to consider factors such as strategy environment adaptability, risk - return characteristic persistence, and management team moat depth [6][90].
