追踪存储芯片行业的Roundhill Memory ETF（代码：DRAM）今日盘前大涨5.01%，成为市场关注的焦点。
消息面上，多重利好因素共同推动了存储芯片板块的乐观情绪。首先，隔夜美股市场中，存储芯片巨头美光科技（MU）股价单日暴涨超过19%，总市值首次突破1万亿美元，带动了整个半导体板块的强势表现。其次，行业数据显示，受人工智能（AI）数据中心建设热潮的推动，2026年第一季度全球DRAM营收环比大幅增长80%，创下历史新高，市场供需持续紧张。此外，三星电子劳资双方达成的薪资协议以高票获得工会通过，此前困扰市场的罢工风险暂时解除，确保了全球存储芯片供应链的稳定。
与此同时，中国最大的DRAM厂商长鑫科技科创板IPO成功过会，彰显了国产存储芯片产业的快速发展，也为全球存储市场增添了新的增长叙事。在AI算力需求爆发、行业周期属性弱化以及全球龙头公司业绩超预期的背景下，存储芯片行业正迎来结构性景气周期，这直接提振了追踪该行业的ETF价格。
