NEW YORK, December 31, 2025, 17:53 ET — After-hours
- Costco shares eased about 0.4% in after-hours trading, last at $862.34.
- A U.S. regulatory filing showed Executive Vice President Javier Polit sold about 2,607 shares worth roughly $2.26 million.
- The next scheduled catalysts on Costco’s calendar include December sales results on Jan. 7 and a quarterly earnings call on March 5.
Costco Wholesale Corp shares dipped in after-hours trading on Wednesday, tracking a softer year-end tape as a regulatory filing disclosed stock sales by a top executive. The shares were down about 0.4% at $862.34.
The timing matters because the final session of the year tends to be illiquid, amplifying small flows. U.S. markets are also closed on Thursday for New Year’s Day, pushing the next regular session to Friday.
Wall Street ended the year’s last trading day lower, with the S&P 500 down 0.74% and the Nasdaq off 0.76%, according to Reuters. Lower volumes at year-end can sharpen late moves in individual names.
In a Form 4 filing with the U.S. Securities and Exchange Commission, Costco Executive Vice President Javier Polit reported selling 2,049 shares on Dec. 29 at a weighted average price of $867.2054 and 558.305 shares on Dec. 30 at $862.895. The sales totaled about $2.26 million and left him holding 10,189.592 shares, the filing showed.
Costco traded between $861.42 and $867.76 during the regular session, according to market data. Other large retailers were mixed in late trading, with Walmart down about 0.5%, Target up roughly 0.3% and BJ’s Wholesale little changed.
For investors, the next company-specific read is Costco’s December sales results, due Jan. 7 on its investor calendar. The monthly report is closely watched for comparable sales — sales at stores open at least a year — a standard gauge of underlying demand.
Costco’s investor calendar also lists its annual shareholders’ meeting on Jan. 15. That meeting can draw attention to governance proposals, capital return priorities and any shifts in long-term strategy.
The next major earnings catalyst is further out. Costco is scheduled to host its fiscal second-quarter earnings call on March 5, the company’s events page shows.
Between those dates, traders typically focus on the same set of levers: membership renewals, paid member growth and the pace of e-commerce. Those metrics tend to drive the stock because membership fees provide a stable profit stream in Costco’s model.
Year-end positioning has also shaped trading across U.S. equities this week, with investors taking profits and recalibrating risk. “I do not expect that the last few days will have so much bearing on the performance of the next year,” Giuseppe Sette, co-founder and president of Reflexivity, told Reuters, pointing to profit-taking when liquidity is low.

When markets reopen on Friday, investors will be watching for any fresh filings and how retail shares trade without the holiday lull. Attention then shifts quickly to Costco’s Jan. 7 sales report as the next near-term checkpoint for demand heading into 2026.
