US equity indexes rose in a broad-based rally, as chipmakers boosted technology to the top of sector charts and helped offset a move higher in crude oil amid renewed threats of more hostilities in the Middle East.

The Nasdaq Composite jumped 1.3% to 25,837.21, with the S&P 500 up 0.9% to 7,509.20 and the Dow Jones Industrial Average higher by 0.7% to 52,224.64 on Tuesday. Technology was the standout performer, up 2.4%, followed by energy. Consumer staples and communication services were the sole decliners.

"That's hoped to boost the earnings outlooks for the hardware makers."
