8月6日，MKS仪器盘中下跌7.67%，报297.555美元/股，成交额5997.85万美元。
消息面上，公司盘后发布二季度财报，调整后每股收益3.30美元，超出市场一致预期的2.96美元，同比增长86.44%；收入12.48亿美元，高于预期的12.06亿美元，同比增长28.4%。三季度指引同样超预期，预计调整后每股收益3.58美元（±0.31），收入13.5亿美元（±4000万），均高于分析师预期。
尽管业绩与指引双双超预期，但此前财报发布前股价已连续走强，8月4日单日涨幅超5%，短期累计涨幅较大，获利资金离场压力集中释放。叠加半导体设备板块当日整体承压——应用材料跌1.61%、拉姆研究跌1.37%、科磊跌1.0%——板块情绪偏弱进一步放大调整幅度。
