WASHINGTON (MarketWatch) - The output of the nation's factories, mines and utilities rose 0.9% in January, the Federal Reserve said Wednesday. The increase was in line with forecasts of economists surveyed by MarketWatch. Factory activity alone rose 1.0% after slipping 0.1% in December. Industrial production was revised up to 0.7% rise in December from the prior estimate of a 0.6% gain. Capacity utilization - a gauge of slack in the economy -- rose to 72.6% in January from 71.9% in December. This is the highest level since December 2008.
