周五盘中，纳指三倍做空ETF（SQQQ）大涨5.46%，引发市场广泛关注。这一涨势主要源于美国科技股的大幅下跌。
据报道，纳斯达克100指数期货盘前大跌1.66%，多只明星科技股遭遇抛售。特斯拉跌超5%，英伟达和美国超微公司跌超3%，谷歌和Meta跌超2%。这种普遍性下跌直接推动了做空纳斯达克指数的SQQQ上涨。
造成科技股下跌的原因主要有两个方面。首先，市场对科技股，尤其是人工智能相关股票的估值过高产生担忧。华尔街金融巨头花旗集团在第三季度大幅削减了包括英伟达、微软、苹果和亚马逊在内的科技巨头持仓，反映出机构投资者对"AI泡沫"的担忧。其次，美联储官员的鹰派言论也对市场情绪产生影响。多位美联储官员表示，由于通胀担忧和劳动力市场依然稳健，进一步放松货币政策的门槛较高。这些言论打压了投资者对于美联储可能在12月降息的预期。
