NEW YORK, Jan 4, 2026, 11:18 ET — Market closed
Costco Wholesale Corporation shares slipped 0.9% on Friday to close at $854.50, a soft start to 2026 for the warehouse club operator. U.S. markets are closed for the weekend, leaving investors looking to the company’s next sales update for direction.
The timing matters because Costco’s monthly sales report can move the stock quickly, offering a near real-time read on store traffic and online demand coming out of the holiday season.
It also lands as traders reset for January, with the next U.S. labor-market report in focus as a key macro event that can shift rate expectations and consumer sentiment in a single session.
On Friday, Costco traded between $852.50 and $863.10 and was little changed after hours at $854.69, according to Investing.com data. The stock’s 52-week range is $844.06 to $1,078.23, putting it about 21% below its high and just over 1% above its low.
The broader tape was mixed in the first trading session of 2026, with the Dow and S&P 500 ending higher and the Nasdaq nearly flat, Reuters reported. Joe Mazzola, head of trading and derivatives strategist at Charles Schwab, described a “buy the dip, sell the rip” mindset in recent trading. Reuters
Costco’s investor calendar shows it will post December sales results on Jan. 7 at 1:15 p.m. Pacific (4:15 p.m. ET), after the U.S. market close. Investors typically focus on comparable sales — sales at stores open at least a year — and how much growth comes from higher traffic versus higher average tickets.
In its most recent quarterly update, Costco said first-quarter net sales rose 8.2% to $65.98 billion for the 12 weeks ended Nov. 23. Total company comparable sales rose 6.4%, and “digitally-enabled” comparable sales rose 20.5%, the company said.
Costco said membership fees were $1.329 billion in the quarter, a line item investors treat as a high-quality earnings driver because it is recurring revenue tied to renewals.
The January 7 update will also be read against a competitive landscape that includes Walmart’s Sam’s Club and BJ’s Wholesale Club, as big-box and club retailers keep leaning into value as households stay price-sensitive.
But a softer December read — especially if traffic cools or online demand slows — would leave Costco with less room for disappointment near the low end of its yearly trading band. Costco has flagged employee costs such as wages and healthcare, fuel and commodity moves and foreign-exchange swings among factors that can pressure results.
Beyond sales, Costco’s annual shareholder meeting is scheduled for Jan. 15 at 2 p.m. Pacific and will be held in a virtual-only format, a proxy filing showed. The company has also scheduled its fiscal second-quarter earnings and February sales results for March 5, followed by an earnings call later that day.
The next catalyst for Costco shares is Jan. 7, when the company releases December sales after the close. Traders will watch whether the report confirms steady traffic and online momentum — and they will weigh it against next week’s labor-market data, a macro test that can swing retail stocks broadly.
