A gauge of U.S. factories topped estimates in March, rising from a two-year low on strength in employment and orders and signaling stabilization after a rocky few months.

The Institute for Supply Management index rose to 55.3 from 54.2 as three of five main components increased. The result topped estimates in a Bloomberg survey calling for a rise to 54.5 and remained above the 50 level that indicates expansion. Measures of deliveries and inventories decreased.

The reassuring reading may signal the worst is over after months of mounting pressure in manufacturing sent the gauge tumbling from a 14-year high in August. The bounce brought the factory gauge back up toward its 12-month average.

The biggest contributor to the better March reading came from employment, which snapped a three-month slide with the biggest gain in three years. That's a sign of labor-market resilience before Friday's March jobs report, which is forecast to show hiring rebounded from a weak February.

While the Federal Reserve has pledged patience on interest rates, factories still face hurdles as the economy cools and the global outlook dims. Figures released last week showed fourth-quarter growth cooled more than initially reported, and economists project the first-quarter expansion pace slowed to 1.5 percent, the weakest in three years.

Readings for export orders and imports both fell to fresh two-year lows, the latest evidence that the extended trade war with China is taking more of a toll on economic growth.
