Costco Wholesale Corporation (COST) closed at $925.35 on September 4, 2026, a decline of 0.34% over the prior 24 hours. The warehouse retail giant's market capitalization stood at $411.76 billion at the close of trading.
The daily dip extended a broader pullback for the stock. Over the past seven days, COST fell 1.00%, and the 30-day performance showed a steeper slide of 2.38%, reflecting sustained selling pressure over the past month.
The consecutive losses across the one-day, seven-day, and thirty-day windows point to a consistent downward drift in the stock's recent trading pattern. No single session accounted for the entirety of the decline, with pressure spread across the measured periods.
Costco remains one of the largest retailers by market capitalization. The stock's current price of $925.35 reflects the cumulative effect of the recent trading activity across all three tracked timeframes.
