Stock market today: Dow, S&P 500, Nasdaq waver as Nvidia milestone, Trump tariffs vie for focus

US equities traded mixed on Thursday, with the Nasdaq pausing its Nvidia-fueled rally after the chipmaker surpassed a $4 trillion market cap, as investors weighed renewed Trump tariff threats against positive Q2 earnings. Delta Airlines' strong beat and restored guidance, citing trade clarity, offered a counterpoint to new tariff warnings targeting Brazil and BRICS nations. Meanwhile, unexpectedly lower jobless claims further complicated the Federal Reserve's rate decision, reinforcing expectations for a July rate hold.

Analysis

US equity markets exhibited a divergent performance, with the Dow Jones Industrial Average rising 0.5% while the tech-focused Nasdaq Composite retreated 0.2% from a record high. This dynamic reflects a market grappling with conflicting catalysts. On one hand, the artificial intelligence theme remains potent, highlighted by Nvidia (NVDA) becoming the first public company to surpass a $4 trillion market capitalization. On the other hand, renewed geopolitical trade risks are creating headwinds, specifically President Trump's threat of a 50% tariff on Brazilian imports and a potential 10% on BRICS nations. Providing a crucial counterpoint, Delta Air Lines (DAL) initiated the earnings season with a strong report, beating revenue and profit expectations and causing its shares to jump 12%. Critically, Delta restored its earnings outlook, citing 'greater clarity' on trade, suggesting some corporations are successfully navigating the uncertain environment. This complex picture is further compounded by economic data; a surprise drop in weekly jobless claims to 227,000 suggests a resilient labor market, complicating the Federal Reserve's timeline for potential interest rate cuts and reinforcing market expectations for a rate hold in July.

Key Decisions for Investors

• Given the divergence between indices and conflicting macro versus micro signals, investors should assess portfolio balance, as strength in specific sectors like industrials, evidenced by Delta's performance, may offer a hedge against potential profit-taking in high-momentum tech.
• The combination of Nvidia hitting a $4 trillion valuation and the Nasdaq's subsequent pause suggests that investors in the AI space should monitor for signs of consolidation or rotation and consider protecting recent gains.
• Delta's positive guidance restoration is a key indicator; investors should closely scrutinize upcoming Q2 earnings reports for similar commentary on trade clarity, as this will be a critical factor in separating resilient companies from those more exposed to tariff risks.
• With strong labor data complicating the Fed's path, investors should anticipate heightened market sensitivity to forthcoming inflation and employment reports, as these will be pivotal in shaping expectations for a potential rate cut in September.
