IBM今日盘中大涨5.05%，引起了市场的广泛关注。
消息面上，此次股价上涨主要得益于公司宣布了一项重大半导体技术突破。当地时间6月25日，IBM推出了全球首个亚1纳米（Sub-1nm）芯片制程技术，成功将制程节点推进至0.7纳米级别。这项革命性的技术采用了全新的3D“纳米堆叠”晶体管架构，在指甲盖大小的芯片上集成了近1000亿个晶体管，预计可带来高达50%的性能提升或70%的能耗降低。这一突破被视为将推动芯片领域创新再持续10年，极大地提振了市场对IBM在人工智能和云计算时代技术领先地位的信心。
此外，近期多家投行如摩根大通和摩根士丹利上调了IBM的评级与目标价，形成了多重利好共振，进一步推动了股价的强劲表现。
