While analyst narratives paint Costco as undervalued, the company’s price-to-earnings ratio is much higher than industry norms. At 50.6x, Costco trades significantly above its industry average of 20.8x and peer average of 22.4x and also exceeds its own fair ratio of 29.4x. This steep premium suggests that much of Costco’s growth story could already be reflected in the shares, raising questions about how much room is left for upside.
