Costco Wholesale Corporation (COST) closed at $920.97 on October 3, 2026, rising 0.65% over the prior 24-hour period. The gain offered a brief respite for shareholders who have watched the stock drift lower over a broader time horizon.
Over the past seven days, COST has slipped 0.21%, and the 30-day window shows a decline of 0.81%. The modest pullbacks across both periods suggest the stock has faced light but persistent selling pressure in recent weeks, even as the daily session turned positive.
Costco's market capitalization stood at $405.56 billion as of the closing price, reflecting the company's continued standing as one of the largest retailers by market value. The figure underscores the scale of investor capital tied to the warehouse retail giant.
The combination of a small daily advance and slightly negative medium-term returns points to a stock trading within a relatively tight range. The 30-day decline of 0.81% remains modest in absolute terms, leaving COST near its current price level heading into the next session.
