Wholesale inventories fell 1.1% in October, the largest drop in seven years, the Commerce Department said Wednesday.
The decline followed a revised 0.4% decrease in September, Commerce said.
Sales decreased 4.1%, the most since records began in 1992.
The inventory reading was lower than the 0.2% decrease forecast by economists, Bloomberg reported.
Wholesale inventories account for about a fourth of total business stockpiles, while retailers and factories account for the rest.
