U.S. manufacturing activity was stronger than expected in June, with rising orders and easing price pressures, according to the monthly survey of Chicago-area purchasing managers.
The closely-watched Chicago Business Barometer broke three months of slowing growth in June, rising to a seasonally-adjusted 61.1 from 56.6 in May, well above the 53.5 consensus among analysts surveyed by Dow Jones Newswires.

Another important detail from this months report was the decline in inventories, which infers that manufacturers will need to produce more to meet demand (they met a portion of current demand simply out of inventories), a good sign for future growth.
