7月28日，应用材料盘中下跌4.85%，报483.09美元/股，成交额3.73亿美元。
消息面上，有大空头之称的迈克尔·伯里此前公开披露对应用材料的空头仓位，并持续加码做空AI及半导体板块，预计相关芯片股整体可能出现约30%的调整，该消息持续发酵令市场承压。此外，市场对AI基础设施巨额支出能否产生回报的疑虑升温，叠加中国光刻机竞争担忧，英伟达、美光科技等AI芯片龙头股普遍走低，费城半导体指数较6月历史高点已下跌逾20%。半导体设备板块全线重挫，拉姆研究跌7.64%、科磊跌6.14%、阿斯麦跌5.16%。值得关注的是，此前汇丰、花旗、瑞银密集上调应用材料目标价至683至705美元区间，但短期空头情绪仍主导市场走势。
