消息面上，由于美国国债收益率和原油期货价格回落等因素影响，截至9月21日收盘，美股三大指数集体上扬，纳斯达克指数创下自6月初以来的收盘历史新高。外汇经纪商嘉盛集团资深分析师Jerry Chen表示，理论上来说，加息对股市尤其是成长性科技股是利空，但此次鹰派加息对美股的影响似乎比想象中更温和，且科技股展现韧性。从各周期走势来看，纳斯达克100指数整体仍维持在上升结构中。
另值得关注的是，Meta于9月初推出的消费级AI智能体Muse迅速走红，上线约5天内获得73万次下载，累计下载超250万次，登顶美国iOS免费应用榜，超越ChatGPT。受此消息影响，费城半导体指数暴涨4.29%。韦德布什分析师指出，AI智能体的实际算力载体高度依赖CPU，而真正生产AI所需CPU的只有英特尔和AMD两家，这一逻辑带动了整个芯片板块的情绪。
