Roundhill Memory ETF今日盘前股价大跌5.16%,引发了市场关注。该ETF追踪内存与存储芯片行业,其价格波动与全球存储芯片板块的整体表现紧密相关。
消息面上,隔夜美股存储芯片股集体遭遇重挫,美光科技、西部数据、闪迪等个股均跌超8%,SK海力士ADR亦大跌9%。这一跌势迅速蔓延至亚洲市场,韩国股市开盘后存储芯片巨头SK海力士与三星电子股价暴跌,并触发指数熔断。多重利空信号叠加是导致板块情绪急转直下的主要原因:首先,巴菲特警告AI主题投机盛行,引发了市场对相关板块估值过热的担忧;其次,机构报告指出客户对DRAM芯片近30%的涨价幅度强烈抵制,并下调了三季度价格增长预期;此外,韩国检方突击搜查多家半导体零部件公司在韩办公室,调查涉嫌价格串通,美国也对特定DRAM设备启动337调查,这些监管层面的不确定性进一步打压了市场情绪。
整体来看,全球存储芯片板块正承受获利回吐与基本面预期修正的双重压力。尽管长期需求受到AI算力爆发的支撑,但短期内的情绪逆转、监管风险以及客户对高价的抵制,共同导致了此次板块性下跌,并拖累了追踪该行业的ETF表现。
