Business inventories rose 0.9% in January, the Commerce Department said Friday.
The increase followed a revised 1.1% gain in December that was higher than originally reported.
The rise was in line with economists’ forecasts of a 0.9% increase, Bloomberg reported.
Wholesale sales jumped 2%, the most since March.
Factory inventories, which make up about 40% of the total, rose 1.3%, while wholesale inventories, which make up about 30%, increased 1.1%.
When sales are growing, it usually means trucking is seeing additional demand to deliver goods and restock shelves.
