TradingKey - 2026年2月4日,受科技股再度承压拖累,美股收低。标普500指数下跌0.51%至6,882点,而Nasdaq综合指数下跌1.51%至22,905点,表现逊于大盘基准指数,因抛售集中在成长股和半导体股。

在芯片板块中,英特尔(INTC)收跌1.32%至48.60美元,而英伟达(NVDA)下跌3.41%至174.19美元。两者的跌幅均小于超威半导体(AMD),后者面临更沉重的抛压。

作为个人电脑、服务器和游戏主机CPU及GPU的领先生产商,AMD本交易日收盘大跌17.31%,报200.19美元。尽管其2025财年第四季度业绩超出预期,但在公司发布了弱于预期的2026财年第一季度营收指引后,股价大幅下挫。投资者还对利润率压力以及其AI数据中心业务追赶英伟达增长步伐的速度感到担忧。

Uber Technologies(UBER)在发布最新财报后下跌5.15%至73.92美元。该公司第四季度营收增长强劲,但每股收益(EPS)不及市场共识预期,且对2026年第一季度给出了谨慎指引。投资者的注意力正转向Uber的利润率前景及其在自动驾驶和无人驾驶出租车(robotaxi)项目上的进展。交易量激增至6280万股,是其2040万股三个月平均水平的三倍多。自2019年IPO以来,Uber市值已增长78%。

Palantir Technologies(PLTR)是一家专注于企业和政府的分析平台供应商,股价下跌11.62%至139.54美元。尽管公司公布了稳健的第四季度业绩,且本周早些时候获得了分析师的正面评价,但该股再度面临估值担忧,引发了广泛回撤。

加密货币延续了近期的跌势,比特币大跌逾5%,交投于72,000美元附近,创下数月来最低水平。随着数字资产市场情绪进一步走弱,以太坊也下跌超过5%,触及九个月低点。

大宗商品方面,现货黄金曾短暂收复5,000美元关口,随后回吐涨幅,当日收盘上涨0.3%。现货白银表现出色,上涨3%,因投资者在市场普遍波动中寻求避险。

市场要闻

美国1月私营部门就业增长大幅放缓,预示年初劳动力市场疲软。根据ADP数据,美国1月私营部门就业人数仅增加2.2万人,远低于市场普遍预期的4.5万人。该报告反映出关键行业的增长势头明显减弱,新增就业仅集中在教育和医疗行业。相比之下,专业和商业服务以及制造业出现裁员,凸显出核心行业的结构性阻力。工资同比增速持稳于4.5%。低迷的数据可能会强化美联储对经济的谨慎立场。与此同时,由于美国政府持续停摆,官方非农就业报告再次推迟发布。

Alphabet (GOOGL) 的激进AI投资策略推动了营收增长,但也引发了股价波动。Alphabet公布了强劲的第四季度财报,总营收同比增长18%,创历史新高。Google Cloud营收激增48%,超出预期9%以上。搜索业务营收也增长17%,超出预期。然而,Waymo及“其他押注” (Other Bets) 部门的营收下降了7.5%,不及预期。公司以AI为导向的支出计划成为焦点:研发费用激增42%,并将2026年资本支出指引的中值上调至1800亿美元,比市场共识高出50%以上。尽管计入了与Waymo相关的21亿美元一次性费用,营业利润率仍保持在30%以上。该股盘后波动剧烈,最初下跌7.5%,随后反弹超过4%,接着再度回落。

SanDisk (SNDK) 大跌16%,领跌受AI驱动的存储芯片股。周三半导体板块——特别是与内存和存储相关的股票——大幅抛售,加剧了科技股的整体回调。SanDisk跌幅接近16%,成为该板块跌幅最大的股票之一,原因是投资者在数月的抛物线式上涨后,纷纷撤出AI受益股。该股在过去六个月中飙升了1100%以上,其中包括在上周业绩超预期后的短短三个交易日内上涨了29%。然而,对基本面走弱的担忧以及获利了结的压力引发了迅速反转,凸显了市场对高估值的敏感度以及对AI相关硬件股情绪的变化。

礼来 (Eli Lilly) (LLY) 业绩超预期,得益于减肥药销售强劲,并上调2026年展望。礼来第四季度营收同比增长43%,净利润增长50%,主要受其GLP-1减肥疗法销售加速推动。对于2026财年,公司发布的营收指引为800亿至830亿美元,超出市场共识。财报结果表明,在竞争日益激烈的减肥药市场份额争夺战中,礼来正占据领先地位。相比之下,竞争对手诺和诺德 (Novo Nordisk) 警告称,由于定价压力,今年营收可能下降13%,而礼来预测增长率最高可达27%。

诺和诺德 (Novo Nordisk) (NVO) 因利润压力大跌,承诺回购以安抚投资者。诺和诺德 (Novo Nordisk) 股价在欧洲交易中下跌18%,此前该公司承认在2026年面临“前所未有的定价压力”。首席执行官拉尔斯·弗鲁尔加德·约根森 (Lars Fruergaard Jørgensen) 承认,其明星减肥药Wegovy大幅降价带来了财务压力,但表示该策略旨在抢占销量并捍卫市场份额。为了稳定市场情绪,诺和诺德宣布了38亿丹麦克朗的股票回购计划和股息派发。公司还寄希望于即将推出的口服版Wegovy,以抵消负面影响。
