Costco Stock's Premium Rests On A Visit Rate That Keeps Slowing
Costco Wholesale (COST) reported 11.6% net sales growth in fiscal Q3 2026, with comparable sales up 6.6%. However, worldwide visits grew only 2.4%, down from 5.2% a year earlier. Management attributes this to normalization and plans physical expansions to boost traffic. COST trades at 46.9 times earnings, near the top of its 10-year range, with shares down 14% from their 52-week high.
