Similarly, the U.S. reported growth in manufacturing activities this morning. The ISM Manufacturing PMI index was 58.4 for January. According to a survey by Bloomberg, it beat the highest estimate of 58 and the median estimate of 55.5.

The index grew for the sixth consecutive month and showed its highest reading since August 2004. New orders, production, employment, backlog of orders, exports, and imports all rose for the manufacturing sector. Inventories decreased in January, but at a slower pace.
