CapitolRadar analysis
54 tracked trades split narrowly toward purchases
54 MCK trades were tracked from 2018-12-23 through 2026-08-10: 29 buys and 25 sells across 6 distinct traders. That is a four-trade difference between purchases and sales, so the aggregate record is only modestly buy-leaning. McKesson Corporation is classified in Healthcare / Medical - Distribution. The trade count is a relatively small sample spread across multiple years, and the supplied data does not attribute the 25 sales to individual traders.
18 of 29 buys came from two disclosed buyers
Ro Khanna recorded 10 buys, the most in the dataset, with the latest dated 2026-08-10. Lois Frankel followed with 8 buys, last dated 2022-03-08. Together, they accounted for 18 of the 29 purchases. Jared Moskowitz, Diana Harshbarger and Josh Gottheimer each made 3 buys, while Markwayne Mullin made 2. Their latest listed purchase dates were 2025-12-02, 2022-10-21, 2022-03-09 and 2026-02-04, respectively. Because all 29 buys are distributed among only 6 people, individual activity can materially affect the overall balance.
12 trades appear in the supplied quarterly snapshots
The listed quarterly observations contain 12 trades, including 8 buys. The buy-only quarters shown are 2026 Q3 with 1 trade, 2026 Q1 with 2, and 2025 Q4 with 2. By contrast, the single trades in 2025 Q3, 2025 Q2 and 2024 Q1 were sales. These snapshots do not cover every quarter in the full tracking period and should not be treated as a complete quarterly series. Among the same buyers, PANW was also purchased by 3, while MNST, AVGO, HD, MSFT and AXP were each purchased by 2. Those overlaps are small samples and do not establish a broader strategy or motive. Congressional disclosures may be filed up to 45 days after a transaction, so reported activity can lag trading dates. Disclosed dollar amounts are generally presented in ranges and are estimates; no transaction amounts were provided here.
