US manufacturing expanded well above estimates last month, fully recovering from the previous month's deceleration.
The Institute for Supply Management (ISM) said its index of national factory activity returned to its fastest growth rate in three-and-a-half years as new orders rebounded sharply.
The index rose to 59 in October from 56.6 the previous month.
That brought the index back to the same level it recorded in August, which had been the highest since March 2011.
The reading exceeded expectations of 56.2, according to a Reuters poll of economists, topping even the most optimistic estimate of 57.3. A reading above 50 indicates expansion in the manufacturing sector.
The employment gauge recovered in October to 55.5 from 54.6 in September, also exceeding expectations, which had called for a reading of 54.8. The new orders index rose to 65.8 from 60.0.
The gauge of prices paid plunged by 6 points to 53.5 from 59.5, compared with forecasts for a reading of 56.3 in the Reuters poll. It was the largest drop in the index since a 7-point drop in March 2013 and coincided with a huge drop in oil prices.
US crude oil futures fell more than 11 percent in October, the largest monthly decline in two-and-a-half years.
