Co. provides merchandise in the following categories: food and sundries, which include dry foods, packaged foods, groceries, snack foods, candy, alcoholic and nonalcoholic beverages, and cleaning supplies; hardlines, which include appliances, electronics, health and beauty aids, hardware, and garden and patio; fresh foods , which include meat, produce, deli, and bakery; and softlines, which include apparel and small appliances. The COST stock yearly return is shown above.
The yearly return on the COST stock yearly return page and across the coverage universe of our site,
is a measure of the annual return over the calendar year 2017 for the given stock.
When performing this calculation it is important to factor in dividends, because a financial instrument's annual return is
more than just the change in price if that instrument pays a dividend or coupon.
One way to factor dividends into the return is simply to count them as cash — we don't do
that here. Instead, our website aims to empower investors
by performing the COST annual return calculation with any dividends reinvested as applicable (on ex-dates).
