Despite trading at a premium compared to Walmart, Costco's revenue growth is nearly double, and its membership model is validated by high renewal rates. The article details Costco's strong fundamentals, including 11.58% revenue growth and 89.7% membership renewal in Q3 2026, while also highlighting risks such as valuation concerns and insider selling.
