Wall Street advanced as better-than-expected reports on the US economy kept alive optimism on the recovery without erasing hopes that US policy makers will still lend a helping hand to accelerate the pace of expansion.
"Reports from the twelve Federal Reserve Districts suggest economic activity continued to expand gradually in July and early August across most regions and sectors," the Fed said in its Beige Book regional business survey.
The US economy grew at a 1.7 per cent annualised pace in the second quarter, according to Commerce Department data. That was better than the government's initial 1.5 per cent estimate a month ago.
All eyes - however - are on Fed Chairman Ben Bernanke's speech at a gathering of central bankers in Jackson Hole, Wyoming, on Friday.
"I don't think this really changes the dovish sentiment of the Fed," Michael Hanson, a senior economist at Bank of America Merrill Lynch in New York, told Reuters. "They are going to look at this and say 1.7 per cent is below trend, that's not where we want to be and the risks going forward are still material."
