2024年10月，在美国金融AI实验室Nof1主办的Alpha Arena AI交易大赛上，上演了一场引人注目的实盘 测试，主办方选出了市场上最领先的6个大语言模型，让它们真金白银管理了一笔资金。 事实证明，即便是全世界最智能的模型，也不能确保"做好投资这件事"——不同模型跑出的投资收益相 差巨大。那么，问题就来了：这是因为模型本身能力的区别还是其他原因？ 在中欧基金量化投资部系统化投资组组长杨柳看来，这个实验是一种极致的尝试，即把大模型直接运用 到最终的投资决策当中，也就是我们常说的"端到端"。但大模型不是万能药，它还不能解决我们所有的 问题。 一．体系进化：从1.0到3.0的量化革命 自2016年推出首只量化产品——中欧数据挖掘混合，中欧基金便开启了"基本面量化"的1.0阶段。其核 心是将深度产业研究与逻辑转化为量化模型，力争前瞻性地捕捉行业拐点。 当时，团队80%的精力用于专家访谈、梳理行业核心逻辑，以研究的广度弥补深度，如同"雷达扫描"一 般，在不同行业中寻找被忽视的机会。 这一阶段的中欧量化已展现出差异化特征。2019年至2021年间，当市场资金集中涌向白酒与新能源赛道 时，中欧的量化模型却关注传统 ...

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].
