6月1日，Monolithic Power Systems盘中下跌3.1%，报1526.41美元/股，成交额2.64亿美元。该股盘前一度大涨6.81%，受半导体板块走强及电源管理IC涨价预期提振，随后常规交易时段获利回吐压力显现，股价自盘前高位大幅回落。
消息面上，电源管理IC涨价潮持续发酵，德州仪器、恩智浦、MPS等大厂计划6月至7月上调产品报价，MPS已于3月发布涨价函并计划7月进一步扩大调价范围。但该股自5月20日1512美元附近修复至52周高点1714美元后，短期累计涨幅较大，快速上行后技术性抛压反复释放，走势与5月27日盘前大涨后盘中转跌的模式类似。当日半导体板块内部分化明显，美光科技涨5.96%、英伟达涨4.96%，但英特尔跌3.85%、美国超微公司跌1.91%。
