The composite purchasing managers’ index for the eurozone—a gauge of private-sector activity across the 20 nations that share the euro—rose to 51.1 this month from 50.9 in July, according to S&P Global, which compiles the index in collaboration with Hamburg Commercial Bank. A reading above 50 in the index points to an increase in activity.
