帮主郑重:美股涨了,但美联储内部“打起来了”
Sou Hu Cai Jing· 2026-02-19 04:03
朋友们,今天凌晨美股收了根小阳线,纳指涨0.78%,英伟达、亚马逊这些老朋友都回来了。但你要是 只看指数,可能会错过真正的大戏——美联储那份会议纪要,简直是一部"宫斗剧"。 先给你翻译一下核心看点:降息派、暂停派、加息派,三派人马在同一份纪要里同时登场。 什么意思?有的官员说,如果通胀按预期下降,进一步降息是合适的;有的说,现在就得按兵不动,等 通胀明确了再说;最狠的是,首次有官员明确提出:不排除重新加息的可能性。你没看错,不是"降不 降",是"加不加"都摆上台面了。 美联储传声筒Nick Timiraos总结得很到位:官员们对劳动力市场的担忧减轻了,对通胀的担忧却增加 了。这就解释了为什么美股涨得那么纠结——不是不想涨,是不知道该信哪一派。 再往下看,科技股的反弹也不是普涨。英伟达涨1.6%,因为Meta说要继续买它的芯片;亚马逊涨 1.8%,因为阿克曼加仓了65%;美光大涨5.3%,因为大卫·泰珀也进来了。这些都不是"AI信仰"的全面 回归,而是个股层面的"贵人相助"。 有机构已经开始讨论:AI抛售潮是不是临近尾声了?但更多交易员的态度是:等英伟达财报出来再 说。毕竟,庞大的资本开支是真金白银在烧,回报却 ...

韩国巨头,竞相扩产
半导体行业观察· 2026-02-19 02:46
SK 海力士正在龙仁半导体集群建设一期晶圆厂,原计划于明年 5 月竣工。目前一期厂房外部结构施 工已过半,规划中的 6 座洁净室已有 3 座同步建设。洁净室是对粉尘、微生物与颗粒物进行严格管 控的专用空间。SK 海力士龙仁一期厂房为三层建筑,规模相当于清州厂区的 6 座 M15X 晶圆厂。 据报道,SK 海力士正计划提前试产,最早可能在明年 2—3 月启动。公司将在龙仁一期率先完工的 洁净室内快速完成设备安装,实现提前投产,主要生产在 AI 时代需求激增的高性能 DRAM(如 DDR5)与高带宽内存 HBM。 三星电子也在平泽建设P4(第四座)晶圆厂,原计划明年第一季度竣工,如今工期有望提前至今年第 四季度,整体缩短约三个月。三星会根据市场行情调整存储与代工设备的配置,P4 厂大概率将生产 目前供不应求的高性能存储芯片。近期有消息称,三星已制定战略,在 P4 厂新建一条10 纳米级第 六代(1c)DRAM 生产线,专门用于 HBM 生产,新线月产能预计可达 10 万 —12 万片晶圆。一位 半导体行业人士表示:"韩国存储厂商正疯狂赶工,提前投产时间表。" 公众号记得加星标⭐️,第一时间看推送不会错过。 随着" ...
云巨头,为何倒向英伟达?

公众号记得加星标⭐️,第一时间看推送不会错过。 当Meta Platforms与英伟达(Nvidia)达成大规模 AI 系统交易时,通常意味着该公司此前的某些开 放硬件计划已无法满足紧迫的算力需求。这与项目延期不完全是一回事,但效果是一样的。提醒一 下,这类情况我们掌握的数据并不多,而如今这家社交网络巨头、AI 模型厂商与 AI 硬件巨头英伟 达之间宣布的巨额合作,已是第三起。 这笔交易远比 Meta 上一次与英伟达的合作规模更大,对英伟达而言价值至少数百亿美元,再加上原 始设计制造商将英伟达芯片集成到 Meta 系统中所能获得的额外收益。 在前两起案例中(几乎可以确定第三起新案例也是如此),一旦 AI 算力需求足够紧迫,Meta 便愿 意放弃自家开放计算项目(OCP)的设计方案。 在超大规模云厂商与大模型厂商中,Meta 的定位略有不同:它不只是为搜索加入 AI 能力,或是打 造能与 OpenAI、Anthropic 等抗衡的通用大模型,同时还高举开源大旗(至少目前是这样)。该公 司还运营着庞大的高性能集群集群,作为旗下各类服务的推荐引擎。这些系统需要CPU 与加速器紧 密耦合,让加速器能直接访问 CPU ...
