Core Viewpoint - The article emphasizes that broad-based indices remain a fundamental investment choice, while index-enhanced funds add value by combining the stability of broad indices with additional returns through quantitative stock selection, factor models, and risk control [3][15]. Market Overview - The A-share market experienced some fluctuations last week, but broad indices like the CSI 300, CSI 500, and CSI 1000 performed well, with high trading activity. The Shanghai Composite Index has maintained a stable position above the 10-day moving average for 19 consecutive trading days, indicating strong market momentum driven by policy expectations and capital inflows [5]. - As of September 3, 2025, the overall valuation levels of major broad indices are relatively high, suggesting that the current market logic is not driven by "undervalued opportunities" [5][6]. Industry Rotation - The speed of industry rotation remains high, with the constructed "industry rotation speed indicator" showing that the A-share market's sector switching rate has accelerated significantly over the past three years, reaching a peak at the end of 2023. Although there was a slight decline in 2024, the current indicator remains above the historical average, indicating that investors often miss out on profits due to rapid changes in market trends [8][9]. - Historical data suggests that when the size rotation speed indicator rises, large-cap stocks tend to outperform, while a decline favors small-cap stocks. The current indicator is above the average, indicating market style instability, making it challenging to rely solely on timing and sector betting [9]. Investment Strategy - In the current environment, focusing on broad indices rather than chasing rapidly changing sector trends is deemed a more rational choice. Relying solely on broad-based ETFs may yield returns equivalent to the index itself, making it difficult to achieve better performance in a high-valuation context. Index-enhanced funds stand out by providing both diversification and market exposure while striving for excess returns [12][15]. - The article highlights three index-enhanced funds with high excess Sharpe ratios: 1. Anxin Quantitative Selected CSI 300 Index Enhanced A, with a one-year excess Sharpe ratio of 1.13, utilizing big data and AI algorithms for stock selection [13]. 2. China Europe CSI 500 Index Enhanced A, with a one-year excess Sharpe ratio of 2.03, maintaining a balanced style and dynamic risk factor exposure [14]. 3. Guotai Junan CSI 1000 Index Enhanced A, with a one-year excess Sharpe ratio of 2.66, focusing on alpha factors and risk control through machine learning [14]. Conclusion - Broad indices continue to be a foundational investment choice, while index-enhanced funds provide an opportunity for excess returns without the need for frequent timing. In a market characterized by volatility and structural trends, index-enhanced funds may serve as a tool for balancing long-term allocation and excess returns [15].
