The reports yesterday showed economic activity was on a weak footing even before a 16-day partial shutdown of the US federal government early in October that is expected to weigh on fourth quarter growth.
Manufacturing production edged up 0.1 per cent last month after advancing 0.5 per cent in August, the Federal Reserve said.
Factory output was held back by a 0.5 per cent drop in computer and electronic goods production. Output of electrical appliances also fell.
While automobile output increased two per cent, that was a sharp slowdown from the 5.2 per cent rise logged in August.
Separately, the National Association of Realtors said its Pending Homes Sales index, based on contracts signed last month, plunged 5.6 per cent to the lowest level since December.
The decline was the largest since May 2010. The index, which leads home resales by a month or two, has now dropped for four straight months. Realtors believe home resales, which dropped in September, peaked in July and August.
The reports come on the heels of data last week showing a gauge of business spending tumbled in September. That data, combined with a disappointing reading on hiring released earlier this month, has offered a dull picture of economic activity.
