Wall Street advanced after a report showed US consumer confidence climbed to the highest level in nine months, bolstering optimism about the nation's economic growth.
A Conference Board report showed its consumer confidence index rose to 104.1 in September, up from 101.8 in August, the strongest reading since August 2007.
Polls showed that Republican presidential nominee Donald Trump was generally seen as having lost in the first US presidential debate with Democratic candidate Hillary Clinton, also underpinning equities.
"You have the perspective that Trump lost the debate and good consumer confidence numbers," Dennis Debusschere, a senior managing director and global portfolio strategist at Evercore ISI in New York, told Bloomberg.
Clinton was deemed the winner of Monday night's debate by 62 per cent of voters who tuned in to watch, while just 27 per cent said they thought Donald Trump had the upper hand, according to a CNN/ORC poll of voters who watched the debate.
