In the last seven days, insiders reported 286 purchases (Form 4 code P) at 75 companies. 119 different insiders bought $386.04M of stock between them. That is down 17% on the $467.77M bought the week before.
The largest single purchase came from BERKSHIRE HATHAWAY INC (10% owner), who bought $67.45M of LENNAR CORP /NEW/ (LEN).
Two or more insiders bought the same stock at 5 companies, which is what we call cluster buying: COE (2 insiders), BPRE (2 insiders), ACCV (5 insiders), REF (3 insiders), AGMB (3 insiders). The cluster page has the 14-day list.
These figures count SEC Form 4 purchases (transaction code P) filed between 2026-10-05 and 2026-10-11. 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.
