In the last seven days, insiders reported 423 purchases (Form 4 code P) at 176 companies. 215 different insiders bought $704.70M of stock between them. That is up 4% on the $679.71M bought the week before.
The largest single purchase came from BERTARELLI ERNESTO (10% owner), who bought $219.00M of Madison Air Solutions Corp (MAIR).
Two or more insiders bought the same stock at 5 companies, which is what we call cluster buying: MAIR (2 insiders), BABA (2 insiders), ATTO (2 insiders), AMR (2 insiders), NGL (2 insiders). The cluster page has the 14-day list.
These figures count SEC Form 4 purchases (transaction code P) filed between 2026-08-24 and 2026-08-30. Code P covers open-market and private purchases. Grants, option exercises and shares withheld for tax are left out, because they are pay rather than a decision to buy. Cite the week number and the dates.
