The latest reports on the US economy pointed to weakness, or at the least slower forward momentum, leading investors to press the brakes on Wall Street's record run.
The Philadelphia Federal Reserve Bank said its gauge of factory activity in the mid-Atlantic region dropped to minus 5.2 in May, while the Commerce Department said housing starts sank 16.5 per cent to an 853,000-unit annual rate in April.
"The US economy is still struggling with lacklustre growth and the recovery is far from self-sustaining, so equity markets are looking for guidance from central banks for their liquidity high," Chad Morganlander, a Florham Park, New Jersey-based fund manager at Stifel Nicolaus & Co, told Bloomberg News.
A separate report showed the consumer price index dropped 0.4 per cent, the biggest slide since December 2008, underpinning expectations the Federal Reserve will maintain its efforts to stoke the pace of growth in the world's largest economy.
"Inflation data was very good. It doesn't put any pressure on the Fed. Investors are confident the Fed will continue to stimulate the economy," Paul Zemsky, head of asset allocation at ING Investment Management in New York, told Reuters.
