行情直击10-12
10月12日，2倍做多MU ETF-GraniteShares盘中下跌9.06%，报21.54美元，成交额1538.93万美元。消息面上，存储芯片板块盘前集体走低，美光科技、闪迪等主要成分股跌幅明显，杠杆效应下该ETF跌幅被进一步放大。
当日美股存储芯片股盘前普遍受压，闪迪跌1.94%，美光科技跌1.99%，SK海力士跌1.54%，西部数据跌1.58%。韩国交易所数据显示，外资持有三星电子股份比例降至46.37%，为2009年7月以来最低；外资持有SK海力士比例自上月底跌破50%后，已连续8个交易日徘徊在49%区间，外资持续撤离加剧了板块整体抛压。
该ETF为2倍追踪美光科技的杠杆产品，标的资产的跌幅经杠杆机制放大后，直接导致ETF盘中跌幅远超个股跌幅，呈现典型的杠杆放大效应。
