McKesson Corporation (MCK) closed at $899.36 on October 2, 2026, marking a 5.26% gain over the prior 24-hour period. The move lifted the healthcare distribution giant's market capitalization to $99.55 billion.
Over the past seven days, McKesson shares have risen 3.48%, reflecting sustained buying interest across the recent trading week. The single-session surge was the primary driver of that weekly advance.
Despite the short-term strength, McKesson's 30-day performance remains in negative territory, with the stock down 0.84% compared to where it stood a month ago. That figure suggests the session's gains partially offset a broader period of pressure on the shares.
McKesson is one of the largest pharmaceutical distributors in the United States. Its stock price and market capitalization figures place it among the higher-valued names in the healthcare sector as of the October 2 close.
