Equities declined on both sides of the Atlantic, continuing the trend of January, as data showed that China's manufacturing fell last month, while US manufacturing activity grew at the slowest pace in eight months, fuelling concern about global growth.
The US Institute for Supply Management's factory index dropped to 51.3 in January, from 56.5 in December. China's purchasing managers' index fell to 50.5 in January, from 51 in December.
American car makers did not provide positive news either. Ford and General Motors both reported bigger-than-expected falls in January car sales blamed on unusually cold winter weather. Shares of Ford dropped 3 per cent, while those of General Motors shed 1.7 per cent.
"Given the difficult weather in our largest sales regions, we are fortunate to have held in at retail as well as we did," John Felice, Ford vice president, US marketing, sales and service, said in a statement. "In areas where the weather was good, such as in the West, sales were up. The poor weather also had an impact on the timing of some of our fleet deliveries."
In afternoon trading in New York, the Dow Jones Industrial Average dropped 1.4 per cent, the Standard & Poor's 500 Index sank 1.5 per cent, while the Nasdaq Composite Index shed 1.8 per cent.
