U.S. factory production edged up in August as resilient business investment offset more limited output of consumer durable goods. The 0.1% rise in manufacturing output last month followed an automobile-fueled 0.6% July advance, according to the U.S. Federal Reserve. Including mining and utilities, total industrial production declined 0.2% in August. The median forecast in a Bloomberg poll of economists called for a 0.1% drop in factory output and no change in total industrial production.
