Shares of Costco Wholesale slid 3.9% to $955.94 on May 29, extending a bruising retreat that has now erased more than $140 per share — roughly 13% — from the stock's $1,096.50 record high set just ten days earlier. The catalyst is paradoxical: a blowout fiscal Q3 report that gave investors who had ridden a long rally a reason to cash out.
The Numbers Were Excellent, but the Stock Was Already Priced for Perfection. Net income rose 15.2% to $2.19 billion, with diluted EPS climbing to $4.93 from $4.28 a year earlier.
Net sales jumped 11.6% to $69.15 billion, as record gasoline volumes and surging e-commerce drove results above Wall Street expectations.
Total revenue, including membership fees, reached $70.53 billion, beating the $69.62 billion consensus. But heading into the print, the stock was trading at a P/E ratio of roughly 52 — one of the richest valuations in all of retail. When expectations are that high, even a beat gives nervous holders an excuse to sell.
Shoppers Flooded In for Gas, Groceries, and Gold — but Margins Quietly Slipped. CEO Ron Vachris said the final five weeks of the quarter became Costco's top five volume weeks ever as customers searched for cheaper gas.
Digitally-enabled comparable sales soared 21.5% , and top sellers included pharmacy, home furnishings, and gold and jewelry. Yet gross margin fell 21 basis points year over year, dragged down by lower margins in fresh food and sundries , while SG&A expenses were pressured by higher healthcare costs and legal settlements. For shareholders, the question is whether traffic-driven revenue can keep outrunning cost creep.
The Membership Engine Keeps Humming — and That's What Matters Most. Paid executive memberships grew 9.6% to 41.2 million, total paid members reached 82.9 million, and the U.S./Canada renewal rate ticked up to 92.2%. Membership fees are Costco's highest-margin revenue stream; as long as renewals stay above 90%, the company can keep warehouse prices ruthlessly low. Operating cash flow for the first 36 weeks hit $11.13 billion, up from $9.47 billion a year ago , giving management firepower for its aggressive warehouse expansion.
Profit-Taking, Not a Business Problem. The pullback began after the stock reached its 52-week high of $1,097 on May 19 , and options markets had priced in a post-earnings swing of 4.4%, more than double the stock's average earnings-day move.
The analyst mean price target sits at $1,072, implying only about 6% upside — thin cushion for a stock priced for flawless execution. The sell-off looks mechanical, not fundamental, but it underscores Costco's central tension: an almost perfect business trading at a valuation that leaves zero room for stumbles.
