应用材料今日盘中股价大跌5.05%，引发市场关注。
消息面上，此次股价下跌主要受到两方面因素影响。首先，知名对冲基金经理、电影《大空头》原型迈克尔·伯里公开宣布做空应用材料，认为人工智能相关股票涨幅已过度，费城半导体指数较其200日均线溢价超过65%，这一极端水平上次出现于2000年互联网泡沫时期，伯里将此视为行业热潮可能见顶的信号。
其次，公司内部也出现了负面信号。最新监管文件显示，应用材料总裁兼首席执行官Gary Dickerson于近期累计减持了78,321股公司普通股，套现金额约5500万美元。核心高管的大规模抛售行为进一步加剧了市场的谨慎情绪，在外部空头压力与内部减持信号的双重作用下，该股延续了前期的弱势格局。
