Wall Street stocks bounced higher on Thursday as expectations that lower US taxes would fuel corporate earnings added to easing of nerves over US military conflict with Russia in Syria.
Growth stocks including technology, financial and industrial stocks led gains on the main US indexes.
Boeing rose 1.53 percent and was the biggest boost to the Dow, while Microsoft and JPMorgan rose 1.5 per cent each, lifting the S&P 500.
The gains came as first-quarter earnings season kicked off, with the world's largest asset manager BlackRock Inc reporting quarterly profit above Wall Street estimates. Its shares were up 2.6 per cent.
Analysts expect quarterly profit for S&P 500 companies to rise 18.5 per cent from a year ago, the biggest gain in seven years, according to Thomson Reuters.
"We're seeing some early optimism ahead of earnings and there's no bad news for the moment, be it back and forth between Russia and the US or trade war situation," said Andre Bakhos, managing director at New Vines Capital LLC in Bernardsville.
"This is first full quarter with new taxes... that is a variable that could work very positively in the favour of investors."
At 9:45 am ET, the Dow Jones Industrial Average was up 1.18 per cent at 24,474.26. The S&P 500 gained 0.87 per cent to 2,665.14 and the Nasdaq Composite rose 0.91 per cent to 7,133.66.
US President Donald Trump toned down his threats of a swift military strike on Syria, tweeting "Never said when an attack on Syria would take place. Could be very soon or not so soon at all!"
His comments came a day after he tweeted that missiles "will be coming", threatening a military confrontation with Russia in Syria.
Economic data on Thursday also helped the positive sentiment. New applications for US unemployment benefits fell last week, pointing to sustained labour market strength.
The data pushed yields on the US 10-year Treasury notes to a four-day high at 2.82 per cent.
Delta Air Lines jumped more than 2 per cent after the US carrier reported a rise in quarterly revenue, boosted by higher average fares and passenger traffic.
