阿波罗全球管理公司（Apollo Global Management Inc．）首席经济学家Torsten Slok警告称，科技巨头以外的公司未能展现其人工智能支出带来盈利能力提升，这给大型科技股估值带来风险。

　　“我们需要看到美股七巨头以外的公司利润率上升，”Slok周二表示，他使用的是美国科技巨头的简称。“换句话说，标普500指数中其余493只成份股的情况变得非常、非常关键。”

　　Slok表示，华尔街需要看到他所说的标普500指数中其余493只成份股在采用人工智能后，盈利和利润率方面出现积极结果。否则，对估值的怀疑可能会加深，包括对大型科技公司估值的怀疑。

　　“假设利润率要过几年才开始上升。问题在于，七巨头隐含的盈利假设，相对于实际将会发生的情况，是否过高，或者兑现得太快，”他表示，“这对于讨论七巨头如今应该值多少钱绝对至关重要。”
