Abbott Laboratories Stock After Hours (ABT): FDA Win, Holiday Trading Dynamics, and What to Watch Before the Dec. 24 Open
Abbott Laboratories (NYSE: ABT) finished Tuesday, Dec. 23, 2025, modestly lower, even as fresh headlines reinforced the company’s medical-device momentum heading into a holiday-shortened U.S. trading session on Wednesday, Dec. 24. ABT shares closed at $124.54 (-0.53%) and in after-hours trading were last indicated around $124.20 (-0.27%) as of the evening session. Yahoo Finance With markets set for an early close on Dec. 24, and macro data arriving before the opening bell, the setup for Wednesday is less about “big volume conviction” and more about headline sensitivity, thinner liquidity, and risk management—especially for large-cap, widely held healthcare names like Abbott.
