The Dow Jones Industrial Average gained 0.3 per cent to finish at 29,030.22, and the broad-based S&P 500 added 0.2 per cent to 3,289.30.
The tech-rich Nasdaq Composite Index climbed 0.1 per cent to end at 9.258.70. Analysts said the choppy trading session reflects worries about lofty US stock valuations following the market’s surge since October.
