2倍做多MU ETF-Direxion今日盘前出现大幅下跌，跌幅达13.47%，引发了市场的高度关注。
消息面上，此次下跌主要源于市场对存储芯片行业前景的担忧。全球三大存储巨头近期集体宣布大规模扩产计划，三星与SK海力士合计投资高达8800亿美元，叠加美光科技2500亿美元的本土投资计划，引发了市场对行业中长期可能出现产能过剩的深切忧虑。作为该ETF的标的股，美光科技股价已从高点累计回落超过20%，进入技术性熊市。
此外，知名做空投资者伯里此前建立的空头头寸仍未平仓，显示出市场多空分歧依然显著。由于2倍做多MU ETF-Direxion是一只杠杆型ETF，其固有的杠杆效应进一步放大了底层资产价格波动带来的影响，导致了盘前交易中更剧烈的跌幅。
