On December 29th, U.S. Senator Markwayne Mullin disclosed a purchase of between $15,001 and $50,000 in Costco Wholesale shares, representing a vote of confidence from a prominent public figure. This transaction was reported on January 16th and follows a series of similarly sized purchases the senator made in other large-cap names, suggesting a strategic allocation into retail and consumer staples. Such an insider buying event often attracts attention from institutional investors and may underpin near-term support for the shares.

Costco reported fiscal fourth-quarter revenue of $67.31 billion, exceeding consensus estimates by $280 million, while adjusted earnings per share of $4.34 surpassed forecasts by $0.07. Same-store sales grew 8.3% year-over-year, driven by strength in grocery and membership renewals, which now total 81.4 million accounts, up 5.2%. The company declared a quarterly dividend of $1.30 per share—equivalent to a $5.20 annualized payout—representing a 27.9% payout ratio and marking the tenth consecutive year of dividend increases. The cash distribution will be paid on February 13th to holders of record as of January 30th.

Recent filings show Norges Bank initiated a $5.7 billion position in the second quarter, while Kingstone Capital Partners Texas more than quadrupled its stake to over 2.3 million shares during the same period. Laurel Wealth Advisors and Assenagon Asset Management also raised their holdings by more than 90,000% and 1,500%, respectively, in their most recent quarters. Collectively, hedge funds and institutional investors now own approximately 68.5% of Costco’s outstanding shares, underscoring continued confidence in the company’s membership-fee model, international expansion and resilient margins.
