Dow, S&P 500 and Nasdaq hit records as stocks move individually

Wall Street’s latest record run looked less like a broad tide and more like a market sorting winners from stragglers. The Dow, S&P 500 and Nasdaq had all closed at all-time highs, but once the opening bell noise faded, traders were focused on single names, especially NextNav, which surged 10.8% in early trading.

The advance extended a rally that had already been building for several sessions. On Tuesday, the Dow and S&P 500 scaled fresh record highs after strong Hewlett Packard Enterprise results and Alphabet’s AI-related funding commitment reinforced confidence in the buildout of artificial intelligence. Fresh market data also showed the Dow Jones Industrial Average up nearly 0.5%, the S&P 500 ahead 0.1% and the Nasdaq Composite edging higher, with all three posting new record closes. The S&P 500 finished at 7,609.78 and the Dow at 51,307.79.

By Wednesday, the story was no longer just about the indexes. GameStop and Datadog were among the names drawing attention, a sign that traders were still willing to chase momentum, but they were doing it one stock at a time. That kind of dispersion often appears when benchmark indexes are already near peak levels and investors are looking for the next pocket of upside rather than simply buying the entire market.

The backdrop helps explain why the market has stayed resilient. AI optimism has remained a central driver, with investors still treating spending on chips, software and data infrastructure as a multi-year theme rather than a short-lived trade. At the same time, Middle East developments and higher oil prices have kept some caution in the tape, reminding investors that energy shocks can still ripple through margins, inflation expectations and consumer budgets.

That tension matters for households and small businesses. Rising oil prices can feed into transportation, shipping and utility costs, while policy uncertainty makes it harder to plan hiring, inventory and capital spending. The result is a market that can hit fresh highs even as the operating environment outside big tech remains more complicated.

The record-setting run was already in motion by Monday, when all three major indexes reached new intraday highs and closed at records. By Wednesday, the question was not whether the market could keep climbing, but how far a rally led by AI enthusiasm and selective risk-taking could stretch before broader economic conditions started to test it.
