Costco Wholesale (COST) stock has been on an incredible run, leaving most other brick-and-mortar retailers in the dust, up 46.4% year-to-date and around 100% from its 2020 bottom. Despite the recent run, I am bullish on Costco stock, not only for its ability to dodge and weave through an inflationary environment, but because it may have additional upside once the firm has a chance to ramp up on its digital efforts. Undoubtedly, many customers know they're getting a great deal with Costco, even as prices across the board begin to rise.
