Costco Wholesale Corporation (COST) gained 2.93% on September 26, 2026, pushing the stock to $922.95 as buyers returned to the warehouse retail giant after a period of pressure.
The one-day advance extended a modest weekly recovery, with shares up 3.09% over the trailing seven days. Despite that near-term strength, COST remains 3.47% lower over the past 30 days, reflecting a softer stretch for the stock heading into the session.
Costco's market capitalization stood at $397.57 billion as of the close, keeping the company among the largest retailers by that measure. The 30-day decline suggests the single-session and weekly gains have not yet fully reversed the broader pullback.
No corporate announcements were cited in connection with today's move. The price action reflects the figures reported across the one-day, seven-day, and thirty-day periods for COST.
