Equities in Europe and on Wall Street fell as indicators in the euro zone and China tempered optimism about the pace of the global economic recovery.
In early afternoon trading in New York, the Dow Jones Industrial Average slid 0.31 per cent, the Standard & Poor's 500 Index fell 0.40 per cent and the Nasdaq Composite Index dropped 0.53 per cent. The declines come a day after the Dow Jones briefly surpassed the 13,000 level, while the S&P 500 topped its highest close since 2008.
In Europe, the Stoxx 600 index closed the session with a 0.8 per cent decline for the day.
Reports showed that services and manufacturing output in the euro zone unexpectedly contracted in February, while China's export orders dropped in February in the largest decline in eight months.
"The PMIs suggest there is going to be a slow period of economic growth, which opens the danger of weak profits," Richard Batty, strategist at Standard Life Investments, which has US$248.37 billion of assets under management, told Reuters.
The latest earnings held disappointment too. Dell shares shed more than 6 per cent after the personal computer maker's revenue predictions fell short of expectations. Rival Hewlett-Packard is due to report results later today.
