About Costco (COST)
Costco Wholesale runs a worldwide network of bulk-sale warehouses where only members can shop. A large part of the profit comes from the membership fees paid by members, rather than from product margins — a business model that builds loyalty and produces predictable revenue. It sells everything from groceries to electronics, fuel and services.
It trades on the Nasdaq under the ticker COST and is part of the S&P 500. It is seen as a quality, steadily growing company; it pays a regular dividend and, occasionally, special (one-off) dividends.
