NYSE:MCK 24 September 2025 - 6 February 2026

Shares of McKesson Corp jumped roughly 16.5% to $957.80 in after-hours trading, following a strong rally earlier Thursday.

McKesson Corporation ended the Christmas Eve session essentially flat, then edged slightly lower in thin after-hours trading—an unsurprising setup for a holiday-shortened day when liquidity typically dries up and price moves can be noisy.

McKesson Corporation ended the week on a steadier footing after an early-week dip, closing Friday at $813.80. The stock is still down roughly 9% from its late-November 52‑week high, but it remains one of healthcare’s stronger large-cap performers in 2025 as investors continue to reward its specialty-drug and oncology momentum, capital returns, and portfolio reshaping narrative.
