在华尔街流行一句玩笑：" 如果你不知道自己买的是什么，那八成你买的就是科技股 。"放在今天的美股上，这句话格外贴切。标普500的前十大成分股， 合计 占到整个指数市值的40%。 其中 有八家都被贴上了"科技"标签，剩下的两家是银行股。更夸张的是，自今年4月市场见底以来，这十家公司贡献了标 普500 超过一半的涨幅 。换句话说，美国股市的表现，几乎就是"科技股"的代名词。 乍一听，这没什么问题。毕竟，这些巨头真金白银地在赚钱：它们贡献了指数过去一年三分之一的收入增长、一半以上的利润增长和资本开支增长。没有它 们，标普500的盈利恐怕要黯淡不少。从投资者的角度看，把钱投到能赚钱的公司里不是理所当然吗？微软、苹果、亚马逊、谷歌、英伟达、Meta……这 些名字就像是当代经济的代名词。 可问题在于，鸡蛋都放在一个篮子里，再结实的篮子也容易让人心里打鼓。市场高度集中，本身并不是罪过，但如果集中在同一条叙事链上，风险就会被成 倍放大。这就像一辆跑得飞快的高铁，列车加速没错，但所有人都挤在头两节车厢里，一旦刹车，受冲击的也正是这里的人。 更麻烦的是，"科技股"这个大筐，本身就是个偷懒的分类。苹果是硬件+服务，微软是软件和云， ...
