S&P 500 hits record high as Nvidia results butress AI rally

The S&P 500 reached a record high, largely propelled by Nvidia's quarterly results which, despite excluding potential China sales from its forecast, confirmed robust spending on AI infrastructure and a 56% surge in revenue. This reinforced the ongoing AI-driven market rally, with other AI-related stocks also gaining. Concurrently, lower-than-expected jobless claims, rebounding corporate profits, and high expectations for a Federal Reserve interest rate cut further underpinned broad market gains.

Analysis

The S&P 500 and Nasdaq have reached new record highs, driven overwhelmingly by sustained strength in the artificial intelligence sector. Nvidia's quarterly results served as a primary catalyst, with a 56% surge in revenue confirming robust AI infrastructure spending, even as its stock dipped nearly 1% due to the company excluding potential China sales from its forecast. The market interpreted this not as a sign of weakness, but as a reaction to extremely high expectations, reaffirming the AI investment thesis. This sentiment lifted other AI-related stocks, including Broadcom (+3%), Snowflake, which surged 22% after raising its 2026 revenue forecast on AI demand, and HP, which rose 2% on demand for AI-PCs. The rally is further supported by a constructive macroeconomic backdrop, featuring lower-than-expected weekly jobless claims, rebounding Q2 corporate profits, and market pricing indicating an over 80% probability of a Federal Reserve rate cut in September. However, a key point of divergence exists, as market breadth remains negative with declining stocks outnumbering advancers on the S&P 500 by a 1.7-to-one ratio, and a sharp 13% decline in Hormel Foods highlights weakness outside the technology sector.

Key Decisions for Investors

• Given the confirmed strength in AI-related spending and positive guidance from companies like Snowflake, investors should maintain focus on the AI value chain, viewing any minor pullbacks in leaders like Nvidia as potential tactical opportunities rather than a change in the fundamental trend.
• Be mindful of the narrow market leadership, as the divergence between advancing tech giants and declining broader market stocks, exemplified by Hormel Foods, suggests concentration risk and potential vulnerability in portfolios not aligned with the dominant AI theme.
• Closely monitor Friday's Personal Consumption Expenditures (PCE) data, as an unexpectedly high inflation reading could disrupt the market's strong expectation for a September rate cut and introduce volatility into rate-sensitive growth stocks.
