7月1日，2倍做多MU ETF-Direxion盘中下跌11.31%，报955.025美元/股，成交额7.89亿美元。该ETF为追踪美光科技股价表现的2倍杠杆产品，标的股下行波动被杠杆放大。
消息面上，多重利空共振压制。韩国三星与SK海力士相继公布总额约5000亿美元的空前扩产计划，分析师指出若新增产能属独立投资，未来十年DRAM市场存在显著供应过剩风险。同时，三星、SK海力士及美光因涉嫌合谋操纵DRAM价格在美国加州联邦法院被提起集体诉讼，原告请求三倍赔偿，三家公司此前均有价格操纵认罪记录，历史前科加重市场担忧。此外，美光CEO Sanjay Mehrotra于6月26日出售逾2.5万股公司股票，套现超2600万美元，高管高位减持进一步加剧谨慎情绪。
