| 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. We show 48 historical shares outstanding datapoints in our COST shares outstanding history coverage, used to compute COST market cap on those dates.|
Understanding the changing numbers of shares outstanding, the changing
share price, and the resulting changing COST market cap history over the course of time is important for investors
interested in comparing COST's market cap history versus its peers.
Many "beginner" or "novice" investors will look at one stock trading at a price of $10 per share and another trading at
a price of $20 per share and think the latter company is worth twice as much. Of course, that is a completely meaningless comparison without also knowing how many shares outstanding there are for each of the two companies,
and then calculating their respective market caps. Comparing the share price of COST versus a peer is one thing; comparing
COST market cap versus a peer is a completely different story.
Furthermore, via fluctuation both in per-share price and in the number of shares outstanding (via issuance of new shares over time, the repurchase of existing shares),
the market cap for a company like COST can fluctuate over the course of history.
With this page we aim to empower investors researching COST by allowing them to research the COST market cap history.
