Costco Gains 0.92% on 8.5% Sales Surge But Trading Volume Slides to 43rd in U.S. Rankings

On August 7, 2025, Costco (COST) closed with a 0.92% gain, trading on a volume of $1.85 billion—a 30.32% decline from the prior day’s activity. The stock ranked 43rd in trading volume among U.S. equities. Recent sales data for the four weeks ending August 3 highlighted net sales of $20.89 billion, an 8.5% year-over-year increase, while year-to-date sales reached $248.35 billion, up 8.1%. Analysts attributed the growth to a high global membership renewal rate and stable shopping traffic, reinforcing Costco’s membership-driven business model. The company also announced a quarterly dividend hike to $1.30 per share, underscoring its commitment to shareholder returns amid ongoing warehouse expansion efforts.

Despite the positive sales momentum, rising labor costs from updated employee agreements remain a key risk. These expenses could pressure operating margins if not carefully managed. The investment narrative emphasizes Costco’s disciplined pricing and operational resilience but notes that near-term catalysts, such as warehouse expansion, remain unchanged. Analysts caution that while revenue trends appear stable, long-term profitability will depend on balancing cost control with growth initiatives.
