S&P 500 and Nasdaq 100 Reach Record Highs on Tech Earnings, Iran Hopes

U.S. equity benchmarks S&P 500 and Nasdaq 100 closed at fresh record levels after a combination of strong technology-sector earnings and renewed hopes for progress in U.S.-Iran talks boosted investor sentiment. The move was driven by a broad advance in AI-related chip and infrastructure stocks that underpinned a wider market rally.

The market impulse intensified after Advanced Micro Devices posted better-than-expected revenue and raised guidance, prompting a sharp rise in chipmakers and related suppliers. Positive results and guidance from other technology companies, together with softer-than-expected ADP employment data, reinforced expectations that corporate investment in AI will sustain revenue momentum. Futures for June E-mini S&P and Nasdaq contracts also rose in premarket trade, signaling continuation of the risk-on tone.

Sector effects were pronounced: semiconductor and AI-linked stocks led gains while energy names lagged amid a drop in crude prices. Falling oil prices eased inflation concerns, contributing to a decline in nominal Treasury yields and supporting valuations for growth-oriented technology names. The combination of easing supply-risk premiums and robust earnings helped lift overall risk appetite across markets.

The developments occur against a backdrop of tentative diplomatic progress between the U.S. and Iran, which if sustained could ease disruptions in the Strait of Hormuz and reduce an important risk premium for global oil markets. Market participants caution, however, that geopolitics remain fluid and that any backslide could quickly reverse energy and inflation expectations, with knock-on effects for equity valuations.

Analysts say near-term market direction will depend on upcoming quarterly reports—particularly from data-center and chip-equipment suppliers—and on whether oil prices and interest-rate expectations remain stable. If corporate guidance continues to surprise to the upside, strategists expect the equity rally to persist; conversely, renewed geopolitical tensions or downside guidance could trigger rotation out of cyclicals and technology names. Traders will closely monitor earnings flows and geopolitical headlines for signals on the sustainability of the gains.
