In recent years, as sector differentiation in China’s A-share market has intensified and investors increasingly seek alpha returns, more fund managers have turned to deeply exploring niche sub-sectors to stand out in a highly competitive landscape. ‘Deeply mining niche sub-sectors’ means moving beyond traditional broad industry allocations—such as consumer goods, technology, or healthcare—and instead focusing on specific segments within industrial chains, such as separator materials in electric vehicles, HJT equipment in photovoltaics, or EDA tools in semiconductors. This strategy relies on in-depth industry research, high-frequency tracking, and sharp insights into technological trends. By targeting high-growth, high-momentum niches that are not yet widely covered by the market, fund managers aim to capture explosive growth opportunities early and generate significant alpha. However, this approach carries higher risks: niche sub-sectors often suffer from lower liquidity, higher volatility, and greater sensitivity to external factors like policy shifts or changes in technology roadmaps. Thus, deep sub-sector mining not only tests a manager’s research capabilities but also demands superior portfolio management, risk control, and psychological resilience. Overall, in a market dominated by structural opportunities, intensive exploration of niche segments has become a key path for active equity funds to build differentiated competitive advantages.
近年来，随着A股市场行业分化加剧和投资者对超额收益的追求，越来越多的基金经理开始极致挖掘细分赛道，以期在高度竞争的市场中脱颖而出。所谓‘极致挖掘细分赛道’，是指基金经理不再满足于传统的大类行业配置（如消费、科技、医药等），而是深入到产业链的更细环节，例如新能源车中的隔膜材料、光伏中的HJT设备、半导体中的EDA工具等。这种策略依赖于深度产业研究、高频跟踪和对技术演进趋势的敏锐判断。通过聚焦高景气、高成长但尚未被广泛覆盖的细分领域，基金经理有望在早期阶段捕捉到爆发性增长机会，从而获取显著的阿尔法收益。然而，这一策略也伴随着较高风险：细分赛道往往流动性较弱、波动较大，且容易受政策、技术路线变更等外部因素影响。因此，极致挖掘不仅考验基金经理的研究能力，也对其组合管理、风险控制和心理素质提出更高要求。总体而言，在结构性行情主导的市场环境下，细分赛道的深度挖掘已成为主动权益类产品构建差异化竞争优势的重要路径。
