Bristol Myers Squibb Co. (CELG.RI) insider trading: who bought and sold

CELG.RI insider activity

129 transactions on file (0 open-market purchases and 4 open-market sales).

Scheduled or decided

4 open-market sales by CELG.RI insiders, between Apr 1, 2026 and Sep 9, 2026.

A sale made under a trading plan agreed months earlier is not the same event as one decided that week, and the filing itself says which.

Discretionary. The box was on the form and was not ticked. The sale was made at the prevailing price without a pre-arranged plan behind it.: $2.29M; 3 filings · 3 people
Planned (10b5-1). The filer ticked the Form 4's 10b5-1 box. The sale ran under a trading plan adopted before the trade, so it is a schedule executing rather than a view taken this week.: None; no sales on file
Not stated. The filing does not say. Either it predates the April 2023 checkbox, or nothing has re-read it since. This tab will not guess which of the other two it was.: None; no sales on file

What each insider held after every open-market trade, over the last twelve months.

The figure is each person’s holding as they reported it. It counts one class of stock and excludes grants, option exercises and shares withheld for tax, so a stake can fall here while somebody’s total holding does not. Since April 2023 a Form 4 states whether a trade ran under a pre-arranged 10b5-1 plan; an older one does not, and those dollars read “not stated” rather than being counted either way.
