Sam Kovacs以211美元做空英伟达:周线跌破200美元,是他判断整个市场转跌的分界线

投资通讯Babylon Burns的作者Sam Kovacs在周五收盘前以约211美元的价格做空英伟达,押注AI交易中最后一批领涨股将接着倒下。他划定的界线是周线收于200美元下方;本周,Alphabet、微软和亚马逊将发布财报。

今年9月,白宫就超级人工智能举行午宴,英伟达首席执行官黄仁勋(左二)坐在马克·扎克伯格与特朗普总统之间,埃隆·马斯克在右。如今,一名做空者押注黄仁勋执掌的公司将带领整个市场走低。

Sam Kovacs是投资通讯Babylon Burns的作者。10月23日周五收盘前几分钟,他以约211美元的价格做空英伟达−0.54% — 英伟达, down 0.54 percent today,而这笔交易其实并非冲着英伟达而来。1 他押注的是,接下来轮到AI交易中最后一批领涨股倒下,被它们撑起的指数也将一同回落。

触发他出手的信号刚刚出现:周线收于212美元下方,跌破了一个上升楔形——一种反弹一轮比一轮弱的形态——而这个楔形又嵌在一个更长的楔形之中。1 他预计一周内股价将下探205美元或204美元;真正关键的界线是周线收于200美元下方,那将是英伟达首次收于长期楔形之外。1 这笔空头仓位不大,用他自己的话说,"把握非常低","很有可能会失败"。1

基建股率先破位,领涨龙头尚未倒下

他的依据是一连串已经发生的走势,而非预测,而且他此前喊对过一次这类拐点:ChatGPT发布后,他投资组合中的博通−0.45% — 博通, down 0.45 percent today股价涨了九倍,他在接近350美元处卖出最后一批持仓。1 美光+2.35% — 美光, up 2.35 percent today、AMD+1.59% — AMD, up 1.59 percent today、思科+1.63% — 思科, up 1.63 percent today和英特尔+1.13% — 英特尔, up 1.13 percent today目前同样远低于各自高点;据他统计,泛林集团−0.28% — 泛林集团, down 0.28 percent today和应用材料+0.32% — 应用材料, up 0.32 percent today均已下跌约一半。1

本月盘面也印证了这一点:10月半导体股累计下跌超过15%。4 用他的话说,英伟达、亚马逊−0.72% — 亚马逊, down 0.72 percent today、苹果−0.24% — 苹果, down 0.24 percent today和微软+0.64% — 微软, up 0.64 percent today"没什么动静",因此如今指数全靠这几只股票支撑;仅微软、Alphabet−0.98% — Alphabet, down 0.98 percent today和亚马逊三家,便合计占标普500指数约15%的权重。1 5

思科$130$106-18.5%
Sam Kovacs在Babylon Burns(投资通讯)中引用的各股高点与2026年10月23日收盘价,以美元计;他还估计泛林集团和应用材料已下跌约一半。英伟达收于211美元附近——正是他口中最后才会倒下的那只龙头。1

据他统计,自2022年10月低点以来,市值最大的七只股票合计新增的市值,几乎相当于其余493只成份股之和。1 领涨股就是指数,领涨股的图就是大盘的图——正因如此,他把英伟达称作全市场最重要的一张图。1

检验论断的是资本开支指引,而非趋势线

龙头股因何倒下,上周的Meta−1.36% — Meta, down 1.36 percent today已给出示范:自由现金流自上市以来首次转负,为其债务投保的成本也创下纪录。4 进入本周,市场的担忧在于:据Evercore−1.37% — Evercore, down 1.37 percent today分析师马克·马哈尼估计,三大龙头的资本开支最高可能再增1000亿美元——上一季度,Alphabet就曾因上调开支预测而大跌。4 3

Kovacs的论断是,未来两三年AI资本开支将不及预期,而这恰恰是楔形形态裁决不了的一环。1 工业板块的旁证也与此吻合:GE航空航天−2.59% — GE航空航天, down 2.59 percent today业绩与指引双双超预期,股价却照跌不误。1

宏观背景正是他的绞索。上周五布伦特原油收于每桶117美元附近,创4月以来新高;外界普遍预计美联储本周三按兵不动,但受能源通胀推动,市场已消化12月加息的预期。1 6 4 微软和Alphabet将于10月28日(周三)发布财报,亚马逊则在周四;后一份财报还牵出自研芯片对英伟达的挑战,详见我们此前的《亚马逊Trainium已能训练AI模型,而不只是运行》一文。5

英伟达若失守200美元,谁的钱会搬家

如果周线果真收在200美元下方,他便以此判断整个市场将在一季度末之前转跌。1 这一步跳跃属于推测,他倒是如实承认把握很低。谁买单看得更清楚:龙头股的追高买家,以及指数持有者——按他的判断,如今被动账户已持有大部分资产,指数持有者几乎就是眼下大多数投资资金。1 受益者则是空头,还有他的能源多头仓位,那是他投资组合里最大的一笔押注。1

《投资者商业日报》(Investor's Business Daily)的统计显示,许多非AI股票正发出买入信号,而标普500指数和纳斯达克指数仍停留在关键点位下方——整个市场的权重恰恰压在正在下跌的那一部分上。2

本周看点很明确:英伟达周线收盘与200美元关口的较量,以及Alphabet、微软和亚马逊的资本开支指引。如果龙头股上调开支而股价照跌,说明在市场顶部连利好也遭到抛售,他描述的连锁反应正在兑现。届时被重新定价的,将是AI基建由谁出资、代价几何,而不是这些模型究竟值不值得学着用。

    OpenAI now decides what Cerebras's wafer is worth

With about $20 billion of $25 billion in contracted business tied to OpenAI and the last lock-ups expiring before the November 12 report, one buyer now sets the wafer's price.
