Costco Stock Is Booming Again—But Is the Price Getting Too High?

At a Costco warehouse outside of Seattle, the parking lot fills up early. Between lines of shopping carts, pickup trucks, minivans, and occasionally an electric sedan move slowly. Some patrons show up before the doors even open, exhibiting a quiet patience that seems out of the ordinary in contemporary retail.

At first glance, the scene inside appears nearly chaotic: shoppers maneuvering enormous carts, workers pushing forklifts between aisles, and enormous pallets filled with cereal boxes. However, a rhythm develops after a short while. Families are comparing prices in bulk. A twenty-pound bag of rice is being loaded by someone. Another patron is heading directly for the well-known $1.50 hot dog stand.

It’s difficult to ignore the loyalty. The history of Costco stock is largely explained by this loyalty.

The warehouse retailer’s market value is now close to $443 billion after the company’s shares recently increased to nearly $1,000. The valuation is almost unexpected for a company that sells televisions, groceries, and large jars of peanut butter. Retail stocks rarely command that kind of admiration on Wall Street.

However, Costco isn’t your average retailer. The core of its operations is membership, which is straightforward but strangely potent. Every year, about 82 million people pay just to be able to shop there. A lot of subscription businesses would be jealous of the 90% renewal rate.

It’s fascinating to study psychology. Customers’ behavior is altered when they pay for access. Customers appear inclined to use the membership card—sometimes frequently—once it is in their wallets. That dynamic generates a steady stream of revenue before a single product even leaves the shelf.

Investors have also taken notice. Recently, Costco reported quarterly revenue of about $69.6 billion, up more than 9% from the same period last year. The net income increased to about $2 billion. Online sales increased by more than 20%, while in-store traffic increased. Analysts weren’t surprised by the results because Costco has a history of consistent growth, but they did support the idea that the model is still effective.

However, there are concerns about the stock’s price. At the moment, Costco has a price-to-earnings ratio above 50, which is a high valuation for any retailer. Such premiums are rarely demanded by even powerful companies like Walmart or Target. By paying those multiples, investors are effectively placing a wager that Costco’s formula will continue to function without significant disruption for many years to come.

It’s a risky assumption. It feels purposefully retro when you stroll through one of the shops. Goods are piled high. The price tags are straightforward. The air is rarely filled with music. Costco still heavily relies on bulk discounts and treasure-hunt merchandising in a time when algorithms and personalized recommendations are becoming more and more important in retail.

Nevertheless, the formula is effective. Shoppers enter aisles with the intention of buying groceries, but instead they leave with enormous flat-screen televisions, jewelry, or kayaks. It seems intentional to be unpredictable. Anything could show up on the next pallet, it seems.

Retailers have attempted to replicate the model. Amazon is still promoting bulk purchases on its website. Membership programs were tested by Walmart. However, it has been surprisingly hard to imitate Costco’s culture, which is a mix of community and thrift.

Workers add to that environment. Costco workers tend to stay longer than those at many competitors, partly because the company pays relatively strong wages and benefits. The difference is apparent if you spend a few minutes close to the checkout lanes. Regular customers and cashiers are having a pleasant conversation. Members are greeted by name by staff.

Perhaps small details. But they accumulate. The company’s finances are subtly stabilized behind the scenes by the membership fees. Whether customers purchase televisions or just browse the store and sample free food, that revenue—more than $1.3 billion in a recent quarter—comes in.

It appears that investors see that structure as being similar to a subscription service. Costco stock may be trading at such high levels because of this perception. Because they feel predictable, subscription-style revenue streams typically fetch higher valuations. Members frequently renew out of habit, even during economic downturns.

The valuation argument is still ongoing. The stock, according to some analysts, leaves little opportunity for error. The market may reevaluate its willingness to pay for the company’s earnings if sales growth slows or consumer spending declines. There are many instances in retail history of once-loved chains losing their appeal.

Costco may be an exception. Or it may not. A small indication of the company’s tenacity can be seen when customers leave the warehouse with massive boxes of paper towels. Many consumers seem to have a sincere attachment to the brand. Spreadsheets have a hard time capturing that emotional connection. The cultural aspect is another.

Online, Costco has become somewhat of a phenomenon—shoppers comparing their favorite seasonal items, influencers filming warehouse hauls, and videos of odd deals circulating on social media. The brand is a shared experience as well as a store. Even though analysts hardly ever acknowledge it, Wall Street observes cultural momentum.

The business is still growing abroad. Today, warehouses can be found in North America, Europe, and Asia. New openings draw crowds more akin to concert lines than grocery shoppers in a number of markets.

The narrative surrounding Costco stock is fueled by this enthusiasm. Investors appear to think the business holds a unique position in the retail industry: it is profitable, dependable, and well-liked by the community. It’s still unclear if that combination warrants a share price of almost $1,000.

However, when you’re standing in a crowded Costco on a Saturday afternoon, you get the impression that the company has discovered something timeless.

groceries in bulk. cheap costs. loyalty to a membership. And a shopping experience that, in an increasingly digital world, feels strangely communal. The market seems prepared to pay more for that, at least for the time being.
