"Moreover, the subseries of the release were pleasing, and while we caution that one month's result is not a trend, the report tentatively suggests that the recent softening in growth momentum is now stabilising," Rabinov said.
ISM's gauge of employment also rose to its highest level since last June, coming ahead of the government's nonfarm payrolls report due on Friday, which is forecast to show the economy added 170,000 jobs in April.
