日月光半导体(ASX)今日盘前股价大幅上涨9.03%，引起了市场的广泛关注。
消息面上，此次大涨的直接催化剂是AMD宣布向台湾地区AI生态系统投资超100亿美元，并明确将与日月光、矽品合作开发下一代基于晶圆的2.5D桥接互连技术（EFB架构）。日月光作为核心封测合作伙伴，将直接受益于该笔大规模投资带来的产能扩充与未来订单预期。
此外，公司股价此前因董事Jeffrey Chen大规模抛售叠加半导体板块系统性走弱，累计跌幅曾超15%，存在明显超跌。当前公司基本面依然稳健，一季度业绩表现优异，封测服务价格已上调5%至20%，先进封装营收目标也上调至35亿美元，并积极扩充AI、高性能计算等高端产能，为股价提供了有力支撑。在板块情绪持续修复的背景下，前期超跌后的技术性反弹需求得到释放，共同推动了此次股价的强劲表现。
