| Costco Wholesale and its subsidiaries are principally engaged in the operation of membership warehouses in the U.S. and Puerto Rico, Canada, U.K., Mexico, Japan, Korea, Australia, Spain, France, Iceland, China, and through a majority-owned subsidiary in Taiwan. Co. provides merchandise in the following categories: foods and sundries, which include sundries, dry grocery, candy, cooler, freezer, deli, liquor, and tobacco; non-foods, which include appliances, electronics, health and beauty aids, hardware, garden and patio, sporting goods, tires, toys and seasonal, office supplies, automotive care, postage, tickets, and apparel; and fresh foods, which include meat, produce, deli, and bakery. The COST average annual return 10 years is shown above.
The Average Annual Return on the COST average annual return 10 years page and across the coverage universe of our site,
is a measure of the annualized return over the past ten years (or specified start date) for a given investment
(up to the end of prior trading session recorded). Arguably, choosing ten years for a measurement
period is on the one hand completely arbitrary, but on the other hand provides a sufficiently long window
to capture long-term trends.
Thus, researching Average Annual Returns is good practice for investors — whether COST average annual return 10 years or other benchmarks/peers
— and when doing so it is also important to factor in dividends, because a financial instrument's annualized return is
more than just the change in price if that instrument pays a dividend or coupon. Our website aims to empower investors
by performing the COST average annual return calculation with any dividends reinvested as applicable (on ex-dates).
