New York, Jan 13, 2026, 18:54 EST — After-hours
- Costco shares edged down roughly 0.1% during Tuesday’s regular trading and saw minimal movement after the close
- A regulatory filing revealed that a senior executive vice president sold 1,500 shares
- Investors are eyeing Costco’s shareholder meeting on Jan. 15 and a sales update coming in early February as the next key catalysts
Shares of Costco Wholesale Corp (COST.O) dipped modestly on Tuesday, holding steady in after-hours trading as investors digested news of a recent insider sale amid the busy earnings season.
This filing matters because Costco is seen as a reliable consumer play, and even minor signals—like insider trades, foot traffic data, or membership growth—can sway the stock amid broader market turbulence. Rate-sensitive shares are also jittery, reacting strongly to inflation figures and changing Fed policy bets.
Costco faces a packed schedule in the coming weeks. The company’s shareholder meeting is slated for Thursday, followed by its monthly sales report in early February. Both events are under close scrutiny for a stock that tends to behave more like a “quality” compounder than your average retailer.
A Form 4 filing with the U.S. Securities and Exchange Commission revealed that Sr. Executive Vice President Russell D. Miller sold 1,500 shares on Jan. 9, fetching an average price of $916.32 per share. After the sale, Miller still holds 8,240 shares indirectly via a family trust, according to the filing. 1
The disclosure came after a strong day for the stock. Costco climbed 2% on Monday, closing at $943.08 and marking its third consecutive day of gains, according to MarketWatch data. 2
U.S. stocks closed mostly lower Tuesday as investors took in early earnings and new inflation figures that dragged Treasury yields down, reigniting bets on several Fed rate cuts this year, the Associated Press reported. 3
Retail stocks showed a mixed bag Tuesday. Target climbed over 2%, but both Costco and Amazon pulled back, according to a separate MarketWatch report tracking key big-box and e-commerce players.
Costco plans to hold its shareholder meeting on Jan. 15, followed by January sales figures on Feb. 4. The company’s fiscal second-quarter earnings call is slated for March 5, according to its investor calendar. 4
Insider sales happen regularly, but the real test for Costco bulls lies in a potential consumer slowdown or a surprise dip in traffic and renewal rates. Either could push investors to rethink the valuation of a stock that’s traditionally traded at a premium.
Traders are set to zero in on headlines from the Jan. 15 shareholder meeting, then shift their attention to the January sales report due Feb. 4, which will offer the first clear snapshot of early-2026 demand.
