2倍做多MU ETF-Direxion（MUU）今日夜盘大涨5.16%，引起了市场的广泛关注。
消息面上，其追踪标的——存储芯片巨头美光科技（MU）即将于本周三美股盘后公布2026财年第三季度财报。市场对美光业绩抱有极高预期，一致预测其Q3营收约345-355亿美元，调整后每股收益同比增长近1000%，毛利率有望达到历史高位。财报发布前，多家大行密集上调目标价，韦德布什将目标价上调至1300美元，Stifel和德意志银行则上调至1500美元，超九成分析师给予“买入”评级。
美光科技在前一交易日因市场情绪波动而大幅下挫，夜盘出现的反弹或与投资者在超跌后博弈财报超预期有关。市场焦点集中在美光Q4业绩指引及HBM（高带宽内存）长期供需展望上，这些因素共同提振了市场情绪，并带动了相关杠杆ETF的走强。
