谁都没想到，就在散户们疯狂抛售可控核聚变概念股的时候，外资却在悄悄做一件完全相反的事。 上海电气跌了25.85%，西部超导从90块砸到65块，海陆 重工、中国核建也都跌超25%，整个板块一片哀嚎。 就在这场暴跌中，北向资金和外资机构不仅没有逃跑，反而在2025年三季度新进了五家小盘央国企。 这些公司的市值大多在30亿到90亿之间，看似不起 眼，却藏着外资的深意。 让人意外的是，这些被外资看中的企业，有一个共同特点：它们不是那些被游资爆炒的"概念股"，而是实打实参与国家重大科技项目的企业。 比如中核科 技，它正在为聚变堆研发阀门；比如理工光科，它的传感器用在了"中国环流三号"装置上。 外资这一次的选股思路，和普通散户完全相反。 哈焊华通更受外资青睐，巴克莱、J.P摩根、美林三家机构一起重仓。 这家公司做的是熔焊材料，听起来传统，但它的产品已经用在了可控核聚变项目上。 三季度以来，它的股价逆势涨了17%。 理工光科的市值只有33亿，但它提供的传感器是"中国环流三号"的核心部件。 J.P摩根新进了66万股，位列第六大股东。 这种小市值的科技型央企，正好符 合外资"低位布局"的口味。 百利电气的情况有点特殊。 它的子 ...
