Christopher S. Boerner (senior executive) discloses dealings in Bristol Myers Squibb Co to SEC (Form 4). Between 2 December 2021 and 10 March 2026, the trades on record add up to 21 filings.

In open-market terms, that means 3 purchases worth €334k on one side and 1 sale worth €1.9M on the other. Taken together, the sales exceed the purchases by €1.5M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 3 share grants and 10 option exercises.

The median purchase comes to €106k. On 3 out of 3 purchases, another insider of the same company was buying within the same 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

The newest entry dates from 12 March 2026: an option exercise, in Bristol Myers Squibb Co. The last insider purchase was made public on 21 February 2025, 604 days ago. Filings reach the SEC (Form 4) feed a median of 3 days after the trade. For comparison, the SEC allows two business days to file a Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
