US stocks: Nasdaq ends sharply higher; chip surge offsets Iran worries

THE Nasdaq ended sharply higher on Thursday (Jul 9), as Micron Technology fueled a rally in chip stocks that eclipsed fears that renewed US and Iranian attacks might prolong the Middle East conflict and fuel inflation.

Teheran said it hit US military targets in Kuwait, Qatar and Bahrain following US strikes against Iran on Wednesday.

The PHLX chip index surged 3.06 per cent, up for a second straight session. The Dow and the S&P 500 also closed higher.

Micron Technology jumped 4.5 per cent after the companylaid out plans to invest more than US$250 billion in the US through 2035, to benefit from demand for memory chips to supply the boom in artificial intelligence. Applied Materials climbed 3.2 per cent and Sandisk surged 7.6 per cent.

AI-related stocks have been volatile lately as investors worried about the sustainability of a rally that has helped Wall Street reach record levels in 2026.

“This is still very much an AI bull market. For a bit, it was starting to broaden out, but that’s contingent on oil prices and interest rates staying anchored, and with this flare-up in the Middle East, that calls that part of the bull market into question,” said Ross Mayfield, investment strategy analyst at Baird in Louisville, Kentucky.

Meta Platforms rose after Reuters reported that the company plans to manufacture AI chips starting in September.

The S&P 500 climbed 0.81 per cent to end the session at 7,543.66 points. The Nasdaq gained 1.30 per cent to 26,206.89 points, while the Dow Jones Industrial Average rose 0.27 per cent to 52,487.41 points.

Seven of the 11 S&P 500 sector indexes rose, led by information technology, up 1.65 per cent, followed by a 1.46 per cent gain in consumer discretionary. Following Thursday’s gains, the S&P 500 is up about 10 per cent in 2026, and it remains down less than 1 per cent from its Jun 2 record high close.
