Costco, the warehouse retailer best known for bulk toilet paper, $1.50 hot dogs and the particular joy of finding a designer handbag next to a pallet of canned beans, is now flirting with a $1,000 stock price. Shares have climbed 15 percent so far this year, sitting at $983 as of Thursday and giving the company a market value of $438 billion — making it one of the most valuable retailers on the planet.
The business performance behind that number is genuinely impressive. The concern is whether the stock price has gotten so far ahead of even impressive performance that there is no longer any room for the company to have a bad quarter without investors heading for the exits.
The sales numbers that are driving the excitement
January sales jumped 9.3 percent compared to the prior year, reaching $21.3 billion for the month alone. For the first 22 weeks of the fiscal year, total sales climbed 8.5 percent to $123.2 billion. Stores open more than a year posted comparable sales growth of 7.1 percent in January — consistent, broad-based growth that most retailers of Costco’s scale would find extremely difficult to replicate.
The standout number is online. Digital sales surged 34.4 percent in January, a significant acceleration from December’s already strong 18.3 percent growth. For a company whose entire identity is built around getting people physically into a warehouse, competing effectively against Amazon in e-commerce is not a small thing.
Membership revenue — the actual engine of Costco’s business model, since the company deliberately keeps product margins thin and makes its money on annual fees — grew 14 percent year over year in the most recent quarter. Shoppers are not just renewing. They are renewing in growing numbers.
Why the valuation is making people uncomfortable
Costco currently trades at approximately 53 times its earnings. For context, most grocery and retail stocks trade at considerably lower multiples. A price-to-earnings ratio of 53 is not just high for retail — it is the kind of number that reflects investors pricing in flawless execution for years into the future with essentially no tolerance for error.
To justify the current stock price, Costco would need to sustain mid-single-digit comparable store sales growth, keep membership revenue rising and expand profit margins consistently — all simultaneously, indefinitely. The company is currently doing exactly that, which is part of what makes the valuation conversation so uncomfortable. The performance is real. The question is whether the price leaves any cushion if anything goes wrong.
Some analysts suggest a price closer to $830 per share would offer a more reasonable entry point with margin of safety built in. The consensus target across Wall Street analysts sits around $1,008, with some firms projecting as high as $1,100 — though that range reflects optimism rather than a resolution of the valuation concern.
What the insiders are actually doing
When the people closest to a company start selling, it is worth noting — not as a definitive signal, but as a data point. One institutional investor recently cut its Costco stake by nearly 70 percent. A company director sold 458 shares in January. An executive vice president sold 1,500 shares earlier that month. Combined insider selling over the past quarter totaled nearly 7,000 shares worth more than $6.3 million.
Insider selling does not always mean trouble is coming. Executives sell shares for many reasons that have nothing to do with company outlook. But at a valuation that has essentially priced in perfection, the fact that insiders are reducing exposure rather than adding is a detail that deserves to sit alongside the sales growth numbers rather than be ignored by them.
The smaller issues beginning to accumulate
Beyond the valuation question, a few operational matters are worth tracking. Costco faces a class-action lawsuit alleging its rotisserie chicken poses salmonella risks — a legal and reputational headache at a moment when the company’s image is one of its most valuable assets. The company is also issuing refunds related to the closure of its Synergy gift card program and recently dropped expansion plans for a new store in Asheville due to local costs and requirements.
None of these are existential. Together they represent the kind of friction that is normal for a company of Costco’s scale — except that at 53 times earnings, normal friction has an outsized effect on the stock. A recent Nike partnership is generating social media attention and driving foot traffic, and the quarterly dividend of $1.30 per share continues to reward long-term holders. For shoppers, the warehouse experience remains exactly what it has always been. For investors, the experience of buying in near $1,000 is a different calculation entirely.
