WASHINGTON (MarketWatch) - The output of the nation's factories, mines and utilities rose 0.1% in October, the Federal Reserve said Wednesday. The gain was due almost entirely to a big jump in utility output. Every other sector except material production was flat or down. The October increase was less than expected by economists surveyed by MarketWatch. Analysts had been expecting a 0.4% gain. Capacity utilization - a gauge of slack in the economy -- rose to 70.7% in October from 70.5% in September.
