Alphabet财报失利引发AI担忧，科技股抛售拖累股指期货下跌

Alphabet（谷歌母公司）因最新财报显示营收未达预期，其股价在盘前暴跌10%，有望创下公司历史上最大的财报后单日跌幅 12。此次业绩滑坡主要归咎于搜索业务面临困境导致收入不及预期，以及现金消耗情况恶化 2。受此影响，市场对人工智能领域支出过度的担忧情绪重现，引发科技板块整体震荡 12。

关于市场指数表现，现有事实包中存在信息冲突：来源1指出道琼斯指数上涨，而标普500和纳斯达克期货下跌；来源2则称道琼斯、标普500及纳斯达克三大股指期货均有所回落。由于无法调和这一矛盾且不得引入外部常识判断哪一来源更准确或更新，此处仅陈述各方报道的具体内容而不做统一结论：有报道显示道琼斯指数上涨，但标普500和纳斯达克期货下跌 1；另有报道指出道琼斯、标普500及纳斯达克期货均下跌 2。

除了Alphabet，微软股价逆势上涨，而卡特彼勒、礼来制药和DoorDash等公司的股票也在盘前经历剧烈波动 2。这一抛售潮还波及全球市场，导致亚洲股市随华尔街期货走势出现波动 1。

Alphabet Inc. shares plunged 10% in premarket trading following a revenue miss in its latest earnings report, setting the company on course for its largest post-earnings decline to date 1. The sharp drop was triggered by concerns over excessive spending on artificial intelligence and worsening cash burn associated with search business challenges, leading to a sell-off in the search giant’s stock and heightened anxiety across the technology sector 12. This sentiment reversal caused Asian equities to wobble and dragged Wall Street futures lower 12.

While S&P 500 and Nasdaq futures fell under the weight of Alphabet’s weak results, reports diverged regarding the direction of the Dow Jones Industrial Average 12. One account noted that the Dow rose despite the tech slump, while another indicated that the index also declined alongside broader market worries about AI-related costs 12. Microsoft shares moved higher even as Google’s parent company struggled, highlighting the mixed nature of the premarket action 2. Other stocks experiencing significant volatility before the opening bell included Caterpillar, Eli Lilly, and DoorDash 2.
