U.S. manufacturing output slumped in October by the most in six months as an auto workers’ strike at General Motors Co. curtailed vehicle production and the trade war continued to weigh on other factories. The 0.6% decline in output followed a 0.5% decrease the previous month, Federal Reserve data showed Friday. Excluding the 7.1% drop in motor vehicle output, which was the largest since January, factory production decreased a more modest 0.1% for a second month.
