BSX

Congressional Activity
BOSTON SCIENTIFIC CORP COMMON STOCK
ARIA INTELLIGENCE BRIEF

Twelve members of Congress have disclosed 61 trades in this Health Care sector security (BSX) across public filings spanning February 2023 through June 2026, with sales outnumbering purchases by a significant margin — 39 sales against 22 purchases, reflecting a net selling posture across the disclosure period. The most active disclosing members by trade count are Gil Cisneros, Michael McCaul, Ro Khanna, and Lois Frankel, and the record shows one bipartisan co-trading cluster that spans both chambers of Congress. Separately, 19 executive-branch officials have disclosed 44 transactions in the same security in independent public filings, with the closest congressional and executive purchase disclosures falling one day apart — a sequence observable in the public record within the standard 90-day proximity window.

Signal Congress surfaces public disclosure data. This is not investment advice and does not imply wrongdoing.
