6月23日，2倍做多MU ETF-GraniteShares盘中下跌22.48%，报830.975美元/股，成交额1.47亿美元。该ETF以两倍杠杆追踪美光科技股价表现。
消息面上，全球AI及半导体概念股遭遇集中抛售，费城半导体指数开盘重挫7%，美光科技开盘跌近11%。韩国KOSPI指数暴跌约10%，SK海力士、三星电子均跌超12%，日经225指数下跌3.55%。摩根士丹利投资管理高级投资组合经理表示，AI受益股持仓过于拥挤，动量交易者追逐导致剧烈回调。与此同时，美光科技将于6月24日盘后公布财报，市场在财报落地前集中进行预期兑现与避险操作，进一步放大了抛压。由于该ETF采用两倍杠杆结构，美光约11%的跌幅对应其逾22%的下行幅度。
