Core Viewpoint - Market style rotation is a typical characteristic of A-shares, where no single style can consistently outperform the market. This rotation significantly impacts quantitative long strategies, influencing their excess returns directly [2][3]. Group 1: Impact of Style Rotation - Style rotation serves as a double-edged sword for quantitative long strategies, affecting performance and sustainability. When market style aligns with historical preferences of quantitative models (e.g., small-cap style), strategies can capture significant stock selection alpha, leading to outstanding performance [3]. - In the first half of 2023 and the small-cap market in 2024, many quantitative products achieved considerable returns. However, when market styles reverse sharply (e.g., collective pullback of small-cap stocks in early 2024), quantitative strategies face significant challenges, often resulting in noticeable drawdowns [3]. - Quantitative models rely on historical data to identify patterns. If a particular style (like small-cap) remains dominant, models will increase exposure to that style. A sudden style reversal can lead to the short-term failure of factors based on historical data, causing stock selection alpha to vanish or even turn negative [3]. Group 2: Performance Disparity Among Strategies - Style rotation exacerbates performance disparities among different quantitative products. Funds focusing on different tracks (e.g., 300 index enhancement vs. 1000 index enhancement) or employing varying style constraints or risk control capabilities will exhibit significant performance differences during style shifts [3]. - The average excess return of over 200 quantitative long strategy products under billion-yuan private equity was approximately -1.69%, with only 22.67% showing positive excess returns, indicating a high exposure to small-cap and growth styles [7]. Group 3: Market Conditions and Future Outlook - The market exhibited significant style switching from August to September 2025, driven by macroeconomic changes, capital flows, and policy expectations. The relative performance of broad-based indices reflects the rotation between large-cap and small-cap styles [7]. - The small-cap factor's return volatility has increased, and the average excess drawdown during rapid style transitions typically ranges from 1-4%, with the potential for a higher average excess drawdown of 8-9% in February 2024. However, subsequent recovery trends are generally smooth [11].

Core Viewpoint - The A-share market's strong rebound has significantly boosted investor confidence, leading to explosive growth in the issuance of new private equity products [1][4]. Group 1: Private Equity Product Issuance - In July, the number of registered private equity securities products reached 1,298, a month-on-month increase of 18%, marking a 27-month high [2][3]. - The total number of registered private equity securities products this year has surged over 60% year-on-year, with quantitative strategies performing particularly well and attracting substantial capital inflows [2][4]. - The cumulative number of registered private equity securities products in the first half of the year reached 5,576, with a total registered scale of 184.13 billion yuan [4]. Group 2: Strategy Distribution - Stock strategies dominated the July registrations, accounting for 887 products, or 68.34% of the total, with a month-on-month growth of 24.58% [5][6]. - Multi-asset strategies and futures/derivatives strategies also showed steady growth, with 162 and 125 products registered in July, respectively [9]. Group 3: Market Dynamics - The strong performance of quantitative strategies has led to a rapid increase in management scale for many quantitative private equity firms, with the top ten registered products all belonging to billion-yuan quantitative institutions [2][6]. - The market's rebound and the outstanding performance of quantitative investments have driven significant capital inflows, reflecting a strong demand for asset allocation [4][7].

Group 1 - The private equity securities fund industry has shown strong performance in 2023, with an average return of 2.52% as of April 30, and nearly 70% of products achieving positive returns [1] - Multi-asset strategy products lead the market with an average return of 2.87%, while stock strategy products follow closely with a return of 2.56% [1] - The performance of futures and derivatives strategies, combination fund strategies, and bond strategies also demonstrated strong market adaptability, with average returns of 2.34%, 2.10%, and 1.87% respectively [1] Group 2 - Index enhancement strategies have delivered impressive results, with an average return of 6.42% and an average excess return of 9.10% as of April 30 [2] - Large private equity firms with over 10 billion in assets have achieved an average return of 7.53% in their index enhancement products, with all products realizing positive excess returns [2] - Smaller private equity firms also performed well, with average returns between 6% to 7% across various asset sizes, maintaining excess returns above 9% [2] Group 3 - The strong performance of index enhancement products is attributed to improved market liquidity, increased trading activity, and high market volatility, which create favorable conditions for excess return generation [3] - The unique "dual-drive" advantage of index enhancement strategies allows them to benefit from overall market gains (Beta returns) while also employing refined Alpha strategies to enhance returns [3] - This structure of "market Beta as a foundation, active Alpha as an enhancement" demonstrates significant competitiveness in the current market environment [3]
