New York, January 18, 2026, 10:43 EST — Market closed.
- Costco shares climbed roughly 0.7% on Friday, keeping the stock close to its recent peak ahead of a holiday-shortened week.
- Late Friday, a director’s trust submitted paperwork for a modest share sale under Rule 144.
- Investors are eyeing two upcoming triggers: a dividend payment scheduled for late January and a sales update expected in February.
Shares of Costco Wholesale (COST.O) edged up 0.7% to close at $963.61 on Friday. Investors appeared to be positioning themselves ahead of a U.S. trading week shortened by the holidays, with an eye on upcoming sales and earnings reports from the retailer.
U.S. markets were closed Monday for the Martin Luther King Jr. holiday, leaving Tuesday’s open with tighter room for positioning and heightened sensitivity to news. For Costco, the key driver remains the monthly sales report.
Costco often behaves like a “defensive growth” stock during market turbulence — its steady demand and membership fees provide a cushion, while its business model handles price pressure better than most retailers. This strength stands out especially when investors rotate between sectors instead of pursuing broad risk.
Retail stocks showed a mixed bag heading into the weekend. Walmart (WMT.N) gained 0.4% on Friday, Target (TGT.N) inched up 0.1%, but BJ’s Wholesale Club (BJ.N) dipped 0.8%.
A filing late Friday revealed the Susan L. Decker Trust — with Decker serving as a Costco director — submitted a Form 144 notice to sell 458 shares under Rule 144. The shares have an estimated market value of about $437,390, with a tentative sale date set for Jan. 16. Rule 144 governs how affiliates can sell stock, imposing volume limits and disclosure requirements. 1
Costco’s board has announced the schedule for its next quarterly dividend. The payout will be $1.30 per share, with an ex-dividend date on Jan. 29 and payment expected Feb. 13. 2
Costco’s calendar is packed before the March earnings call. The company’s investor relations page shows a January sales update slated for Feb. 4. Then, on March 5, investors will get the fiscal second-quarter earnings alongside February sales figures. 3
The broader market mood could still influence trading around Costco. U.S. stocks closed nearly flat on Friday ahead of the long weekend as earnings season kicked off. Anthony Saglimbene of Ameriprise Financial noted most investors would “take that as a win” with the S&P 500 hovering near 7,000. Bruce Zaro from Granite Wealth Management cautioned that mid-January often proves “pretty choppy.” 4
That said, the stock leaves little margin for error. A slip in comparable sales, ticket size, or membership-fee growth could hit harder, especially as the market swings between “safe” and “cyclical” bets.
Costco’s recent monthly sales report, released earlier this month, revealed a 6.2% increase in total company comparable sales over the reported five-week stretch. Digitally-enabled comparable sales surged 18.3%. Investors will look to the Feb. 4 update to gauge if that momentum continues post-holidays. 5
Traders are set to track COST’s moves as it reopens Tuesday and approaches the Jan. 29 ex-dividend date. After that, the February 4 January sales report stands out as the next key event.
