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 showed strong performance in August, with major indices rising significantly, yet the excess returns of stock strategy private equity products were disappointing, marking the worst monthly performance of the year [1][2]. Group 1: Market Performance - In August, the Shanghai Composite Index rose by 7.97%, the Shenzhen Component Index increased by 15.32%, and the ChiNext Index surged over 24% [1]. - Despite the strong market, the average excess return of 3,122 stock strategy private equity products was -1.97%, the worst monthly performance this year [1]. Group 2: Quantitative vs. Subjective Strategies - Quantitative private equity products experienced a notable decline, with an average excess return of -3.94% in August, while subjective private equity products had an average excess return of -1.00% [1]. - The significant decline in quantitative products is attributed to a reversal in style, particularly the outperformance of large-cap stocks over small-cap stocks, and severe sector differentiation due to rapid growth in financing scale [1][2]. Group 3: Consistent Performers - As of August 2025, only 95 stock strategy private equity products achieved positive excess returns for eight consecutive months, representing about 3% of the total [2]. - Among private equity firms with over 10 billion in assets, 46 products achieved positive excess returns for eight consecutive months, all of which were quantitative products, with an average excess return of 0.63% in August and 17.91% year-to-date [3]. Group 4: Top Performers by Asset Size - In the 20-100 billion category, 14 products achieved positive excess returns for eight consecutive months, with an average excess return of 1.83% in August and 22.48% year-to-date [7]. - The top three products in this category were "New Thinking Multi-Strategy 3", "Pansong Micro-Cap Index Enhanced 1", and "Giraffe 7", with year-to-date excess returns of ***% [11]. Group 5: Small and Emerging Firms - In the 5-20 billion category, 13 products achieved positive excess returns for eight consecutive months, with an average excess return of 5.34% in August and 57.58% year-to-date [13]. - The leading product in the 0-5 billion category was "Zijin Yunsong", achieving a year-to-date excess return of ***% [18].
