9月1日，美国超微公司盘中下跌3.02%，报458.165美元/股，成交额6.13亿美元。半导体板块当日集体承压，英伟达跌2.12%、英特尔跌2.9%、迈威尔科技跌3.72%、博通跌1.71%，行业整体走弱拖累AMD表现。
消息面上，近期AMD期权市场持续释放偏空信号：8月下旬以来，多笔大额虚值Put买入及熊市看跌价差组合密集出现，其中一笔高达2688万美元的双买Put组合尤为突出，显示大资金对后市持谨慎态度。同时，董事Joseph Householder拟减持13.5万股、总价约6411万美元，首席技术官Mark Papermaster此前也已进行计划内减持，内部人士连续卖出进一步压制市场情绪。当前AMD市盈率约119倍，估值偏高亦加大了回调压力。
