Will Costco Stock Rebound in 2026?

Why this matters: A high valuation can introduce valuation risk, where the stock price may decline even if the company performs well. This could lead to underperformance or a sudden drop in share price.

Costco's first quarter of fiscal 2026 saw total sales rise by 8.2% year-over-year to $66 billion. Comparable sales increased by 6.4%, with digitally enabled comparable sales up by 20.5%. Notably, international markets are showing robust growth, with comparable sales rising faster than in the U.S.

Membership fees, a crucial revenue stream, grew by 14% year-over-year, boosted by a membership price hike and an expanding membership base. Paid executive memberships rose by 9.1% to 39.7 million, while total paid members increased by 5.2% to 81.4 million.

However, Costco's price-to-earnings ratio of 47 and forward price-to-earnings of 42 raise concerns. The valuation is higher than that of companies like Nvidia, Amazon, and Apple. While Costco's steady growth and competitive advantage justify a high valuation, it also introduces significant valuation risk. Intensified competition from e-commerce players like Amazon and brick-and-mortar competitors such as Walmart's Sam's Club, Kroger, and BJ's Wholesale could also pose challenges.

While Costco's consistent growth and competitive advantages warrant a premium valuation, the current level may be too high, leaving little room for error.

Valuation risk, increased competition from e-commerce and brick-and-mortar rivals, and the possibility of a market correction could impact Costco's stock performance.
