In a filing disclosed on January 12, Representative Gilbert Ray Cisneros, Jr. (D–California) reported the sale of between $1,001 and $15,000 worth of Costco Wholesale stock on December 24. The transaction was executed through the Representative’s 150 Main Street Trust at Bank of America. This marks Cisneros’s first reported trade in the company since taking office in January 2025 and underscores a measured reduction of his exposure to the retailer, which could signal a reallocation of his portfolio ahead of his 2026 reelection campaign.

Costco Wholesale’s latest quarterly results, released December 11, featured earnings per share of $4.34, beating consensus estimates by seven cents, on revenue of $67.31 billion, a 0.4% beat of expectations and an 8.3% year-over-year increase. The company reported a net margin of 2.96% and a return on equity of 29.35%. Analysts surveyed ahead of the filing expect full-year earnings per share of 18.03, reflecting confidence in ongoing membership growth and leverage of private-label product margins.

Institutional and hedge fund ownership of Costco stands at 68.48% of outstanding shares, with recent filings showing incremental position increases by firms such as Ridgewood Investments and Wagner Wealth Management in the low-single-digit percentage range. Meanwhile, insider selling has accelerated: in the past ninety days, executives Tiffany Barbre and Claudine Adamo collectively disposed of over 3,900 shares, representing nearly 0.10% of outstanding stock. These insider and institutional shifts suggest divergent views on near-term valuation, which investors should monitor as the retailer approaches its peak shopping season.
