Why Does COST Stock Spark Debate?
Designed to be a one-stop shop for the suburban consumer, Costco (NASDAQ: COST) is a membership-only retail chain that sells groceries, apparel, toys, and household items, often in bulk quantities.
Two Things to Like:
1. Surging Same-Store Sales Show Increasing Demand
Same-store sales is a key performance indicator used to measure organic growth at brick-and-mortar shops for at least a year.
Costco has been one of the most successful retailers over the last two years thanks to skyrocketing demand within its existing locations. On average, the company has posted exceptional year-on-year same-store sales growth of 7.1%.

2. Economies of Scale Give It Negotiating Leverage with Suppliers
With $303.2 billion in revenue over the past 12 months, Costco is a behemoth in the consumer retail sector and benefits from economies of scale, giving it an edge in distribution. This also enables it to gain more leverage on its fixed costs than smaller competitors and the flexibility to offer lower prices. However, its scale is a double-edged sword because there is only so much real estate to build new stores, placing a ceiling on its growth. To accelerate sales, Costco likely needs to optimize its pricing or lean into international expansion.
One Reason to Be Careful:
Long-Term Revenue Growth Disappoints
A company’s long-term performance is an indicator of its overall quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Regrettably, Costco’s sales grew at a mediocre 7.8% compounded annual growth rate over the last three years. This wasn’t a great result compared to the rest of the consumer retail sector, but there are still things to like about Costco.

Final Judgment
Costco’s positive characteristics outweigh the negatives. With its shares trailing the market in recent months, the stock trades at 43× forward P/E (or $979.55 per share). Is now the time to initiate a position? See for yourself in our in-depth research report, it’s free.
