Costco Wholesale continues to lead retail with strong membership growth, high renewal rates, and expanding free cash flow. However, it faces increasing competition from Walmart and Amazon, who are targeting similar customers with enhanced memberships and digital services. Despite its operational success and double-digit growth, Costco's stock trades at a high valuation of 48 times earnings, requiring sustained 20% annual free cash flow growth to justify this price. The analyst rates Costco as Hold due to its strong competitive moat but warns of significant downside risk at current valuation levels.
Costco's challenge from Walmart and Amazon comes as its stock trades near the upper range of its yearly performance. On Pluang, COST is priced at USD 989.87, down 1.52% for the day as of Oct 28, 2026 02:41 WIB, with a market cap of $445.42 billion. Investor interest remains balanced with 55% buy and 45% sell orders, reflecting cautious optimism amid competitive pressures.
