Better-than-expected manufacturing data from the world's two largest economies helped underpin stocks on Wall Street and in Europe.
The US Institute for Supply Management's index of national factory activity rose to 53.4 in March, surpassing expectations, while China's Purchasing Managers' Index climbed to the highest level in 11 months, rising to 53.1 last month.
In early afternoon trading in New York, the Dow Jones Industrial Average rose 0.61 per cent, the Standard & Poor's 500 Index advanced 0.90 per cent and the Nasdaq Composite Index gained 0.93 per cent.
"The market is telling you it believes the [US] economy has turned around, it has made that corner, it is clearly moving higher-especially compared to Europe and parts of Asia," Ken Polcari, managing director of ICAP Equities in New York, told Reuters.
Investors chose to focus on the positive data.
