Susan Langer: trading record in brief
Susan Langer appears in our data through filings on Biogen Inc. shares, published by SEC (Form 4). We count 4 filings; the first trade dates from 26 June 2023 and the latest from 9 June 2026.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.
Most recently, on 11 June 2026, the filings show a share grant in Biogen Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days. The legal deadline for a Form 4 is two business days after the transaction. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
