周五（11月14日）盘前，纳指三倍做空ETF（SQQQ）大涨5.04%，引发市场关注。这一涨幅反映了投资者对科技股的看空情绪正在增强。
消息面上，美股三大股指期货盘前普遍走低，其中纳指期货跌幅最大，达到1%。这表明市场对科技股的态度趋于谨慎。此外，华尔街金融巨头花旗集团在第三季度大幅削减了英伟达、微软、苹果和亚马逊等科技巨头的持仓，反映出机构投资者对"AI泡沫"的担忧正在加剧。花旗的这一动作被视为对近期全球科技股回调的"AI泡沫论调"的呼应。
然而，市场观点并非一边倒。富国银行在第三季度却增持了包括"科技七巨头"在内的多只科技股，显示部分机构仍看好科技股行情。这种分歧进一步加剧了市场的不确定性，可能导致科技股在短期内波动加剧。在这种背景下，作为纳斯达克100指数的反向杠杆产品，SQQQ的走强也就不足为奇。投资者应当密切关注后市科技股的走势，合理控制风险。
