Business inventories rose 0.4% in April, the Commerce Department reported Wednesday.
The gain followed a 0.3% increase in March. Sales rose 0.2%.
The inventories increase was higher than economists’ projections of a 0.3% gain, Bloomberg reported.
Factory inventories, which make up about two-fifths of the total, were unchanged, but wholesale inventories, which make up about 30%, climbed 0.6%.
When sales are growing, it usually means trucking is seeing additional demand to deliver goods and restock shelves.
