With a market cap of $453.5 billion, Issaquah, Washington-based Costco Wholesale Corporation (COST) is a membership-based retailer that sells high volumes of discounted food and general merchandise through warehouses and e-commerce websites across multiple countries. It offers both nationally branded and private-label products in categories like food, electronics, appliances, apparel, and household goods.
Companies valued $200 billion or more are generally considered “mega-cap” stocks and Costco Wholesale fits this criterion perfectly. It generates revenue primarily from store sales and membership fees, with three membership tiers: Business, Gold Star, and Executive. Costco also provides additional services such as gasoline stations, pharmacies, optical centers, and travel services.
