Costco is a high-quality defensive compounder with a durable membership model, evidenced by FY2025 revenue of $275.2B, net income of $8.1B, and diluted EPS of $18.21, but the stock trades at a 155% premium to peer median P/E and insiders have been consistent net sellers. The valuation leaves no room for error, and we prefer a pullback or a re-acceleration of growth before committing fresh capital. While the business remains steady, the risk/reward at current levels is unfavorable.
Valuation compression
At 53.4x P/E vs. a peer median of 20.9x, any earnings disappointment or rotation out of defensives could contract the multiple sharply.
Insider selling signaling
Insiders disposed of a net $56.5M over two years with 75 disposition transactions and no offsetting open-market buys, hinting at limited near-term appreciation expectations.
Margin headwinds
Rising labor and input costs could pressure operating margins (currently 3.8% in FY2025) despite top-line growth.
Competitive threats
E-commerce incursion or a reinvigoration of competitors like Walmart or Amazon could erode membership loyalty and growth.
