7月2日，迈威尔科技夜盘下跌3.21%，报263.33美元/股，成交额6048.08万美元。消息面上，此前期权市场出现一笔规模达998.80万美元的长期虚值认沽大单，交易者买入2028年1月到期、行权价260美元的PUT共1100张，明确表达机构对后市偏空的方向性押注，持续压制市场情绪。与此同时，半导体板块延续系统性抛压，同行业个股中美光科技跌3.25%、英特尔跌1.87%、美国超微公司跌0.77%、博通跌0.64%、英伟达跌0.45%，板块弱势格局对个股形成共振拖累。此外，AI初创公司Oxmiq融资3500万美元进军定制芯片市场，被视为对迈威尔科技等现有厂商的潜在竞争威胁，进一步加剧市场担忧。
