今日盘中，纳指100ETF（QQQ）大跌5%，引发市场广泛关注。此次下跌与美股大盘整体走势密切相关。
据市场数据显示，美股三大指数今日开盘后持续走低。截至发稿时，纳斯达克指数跌幅扩大至4%，标普500指数下跌3.5%，道琼斯工业平均指数跌2.85%。科技股领跌，其中苹果股价下跌约5%，特斯拉跌4.5%。
尽管美国3月CPI数据低于预期，显示通胀压力有所缓解，但未能提振市场情绪。分析人士指出，投资者可能正在消化此前的大幅反弹，同时对经济前景保持谨慎。值得注意的是，昨日美股曾出现显著反弹，但有观点认为这可能是"回光返照"现象，类似情况在历史上的熊市危机时期多次出现。因此，市场参与者应当保持警惕，密切关注后续经济数据和企业财报等信息，以评估市场走势。
