Costco (COST) stock slips after-hours even as Instacart expands same-day delivery into Europe
Costco shares fell about 1.3% to $940.25 in late after-hours trading Friday. Instacart and Costco announced the launch of same-day delivery websites in France and Spain. The drop followed a broader market decline after U.S. wholesale inflation rose more than expected in December. Investors await Costco’s January sales update on Feb. 4.
