标准普尔500指数周三上涨，华尔街正在为英伟达备受期待的盈利报告做准备，该报告被视为对人工智能驱动的市场反弹的关键考验。纳斯达克指数上涨0.1%，道琼斯指数上涨135点，而英伟达的股价几乎没有变化，尽管期权暗示其市值可能波动2600亿美元。分析师预计，这家芯片制造商的收益将比去年同期增长49%，收入增长53%，尽管英伟达警告称，美国对中国的贸易限制将造成80亿美元的损失。在其他地方，MongoDB上涨了36%，Okta上涨了3%，此前两者都超过了预期，理由是与人工智能相关的强劲需求在Nvidia业绩公布前提振了乐观情绪。凭借4万亿美元的市值和标普500指数中最大的权重，Nvidia的报告被视为更广泛牛市的成败时刻。另外，Cracker Barrel股价上涨超过7%，此前该公司表示，在客户和特朗普总统的强烈反对下，将取消其新标志。

The S&P 500 ticked higher on Wednesday as Wall Street braced for Nvidia’s highly anticipated earnings report, seen as a pivotal test for the AI-driven market rally. The Nasdaq gained 0.1% and the Dow climbed 135 points, while Nvidia shares were little changed despite options implying a potential $260 billion swing in its market value. Analysts expect the chipmaker to post 49% earnings growth and 53% revenue growth from a year earlier, though Nvidia has warned of an $8 billion hit from US trade restrictions on China. Elsewhere, MongoDB surged 36% and Okta rose 3% after both beat forecasts, citing strong AI-related demand that bolstered optimism ahead of Nvidia’s results. With a $4 trillion market capitalization and the largest weighting in the S&P 500, Nvidia’s report is seen as a make-or-break moment for the broader bull run. Separately, Cracker Barrel rallied more than 7% after the company said it will scrap its new logo following backlash from customers and President Trump.
