Astera Labs（ALAB）今日夜盘大涨6.31%，引起了市场的广泛关注。
消息面上，此次股价上涨主要受到市场对公司即将公布的2026年第一季度财报的强烈乐观预期所推动。分析师普遍预测该公司营收和每股收益将实现显著同比增长，而Astera Labs历史上已多次超出市场预期，进一步增强了投资者的信心。此外，投行Stifel于前一交易日重申了对该股的“买入”评级并上调了目标价，理由是其作为AI基础设施关键供应商，受益于超大规模云服务商的持续强劲需求。
同时，行业层面的重大利好也为股价提供了额外动力。Anthropic与亚马逊AWS签署了价值千亿美元的长期算力协议，带动了整个AI产业链的走强。Astera Labs作为亚马逊自研AI芯片Trainium系列的核心供应商，预计将从这一合作中显著受益，相关产品将在下半年开始放量。
