New York, January 15, 2026, 11:00 ET — Regular session
Costco Wholesale Corp shares edged up about 0.5% to $956.04 in early Thursday trading after a Form 144 filing revealed a company officer’s intention to sell stock. Bernstein stuck with its Outperform rating, with analyst Zhihan Ma from Bernstein SocGen Group dubbing Costco the “ultimate compounder” and calling the stock undervalued, according to StreetInsider.

Costco’s stock trades as if steady gains are a given. That makes any surprises tough to swallow, particularly with investors focused tightly on consumer demand and retail margins.
Costco’s stock often reacts fast to even minor changes in traffic, membership fees, and inflation-driven expenses. Insider selling filings catch traders’ eyes too—sometimes they read into them, other times they dismiss them as noise.
A Form 144 signals an insider’s plan to sell restricted or “control” shares, but it doesn’t confirm the sale has taken place. Klauer, the company’s executive vice president and COO of its Northern Division, revealed intentions to offload 1,500 shares worth roughly $1.41 million via Fidelity Brokerage Services, according to the filing.
Bernstein stuck with its $1,146 price target, highlighting Costco’s lofty valuation. The stock trades near the mid-40s on a price-to-earnings basis by one metric. P/E ratios offer a quick look at what investors pay per dollar of earnings, and InvestingPro data referenced in the report showed Costco’s P/E even higher.
Walmart and Target, Costco’s big-box rivals, also saw gains, making Costco’s rise seem more like steady progress than a sudden jump.
Costco’s annual shareholder meeting takes place Thursday, this time online. Chairman Hamilton James will steer the official proceedings, followed by a business update from CEO Ron Vachris, according to company documents.
Last week, the company posted December net sales of $29.86 billion, marking an 8.5% increase from the previous year. Total comparable sales for the five-week period climbed 7.0%. Costco highlighted that “digitally-enabled” comparable sales jumped 18.3%, excluding gasoline and foreign exchange effects.
Insider sale notices usually stem from routine planning, yet the market tends to overreact. Costco’s premium valuation means that even slight signals of slowing sales growth or rising costs could quickly weigh on the stock.
Costco plans to release its January sales figures on February 4, with the fiscal second-quarter earnings call set for March 5, per its investor events calendar.
