应用材料(AMAT)今日盘中股价大幅下挫5.23%，引发了市场的广泛关注。
消息面上，此次下跌受到多重因素影响。首先，知名大空头迈克尔・伯里公开披露其做空头寸覆盖应用材料在内的AI全产业链标的，其核心逻辑在于质疑当前AI热潮的长期价值，并将半导体行业集体扩产视为周期拐点信号，这给相关个股带来了显著的做空压力。其次，美伊紧张局势再度升级推高了市场避险情绪，削弱了风险偏好。此外，半导体设备板块在前期经历急涨后，短期面临较大的获利回吐压力，存储芯片龙头SK海力士等个股的获利了结行为也拖累了整个芯片板块的表现。
市场分析指出，尽管应用材料基本面在DRAM与HBM需求推动下被长期看好，但短期内市场对AI芯片需求可持续性的担忧、地缘政治风险以及板块估值过高后的回调压力共同导致了此次股价的大幅波动。半导体设备板块整体承压，同板块个股也普遍下跌。
