9月14日，三倍做空半导体ETF-Direxion Daily盘中上涨16.97%，报52.105美元/股，成交额10.16亿美元。该ETF以三倍杠杆反向跟踪半导体板块，其大幅走强对应芯片板块集体重挫。
消息面上，多重利空共振拖累半导体板块：Anthropic等AI头部企业联合呼吁放慢先进AI模型开发节奏，引发市场对AI算力需求前景的担忧；中东局势突变推动油价飙升，WTI原油期货报103美元/桶；美联储本周加息预期升温进一步压制风险偏好。美股大科技股普跌，英伟达跌超1.5%，光通信板块同步遭重挫，AXT跌超5%、康宁跌超4%。不过多家机构指出，芯片与算力需求持续超供应，短期抛售或仅为暂时，长期AI算力投资逻辑未被破坏。
