Bills Affecting BIIBLive legislation impacting this stock

Political ProfileWhere BIIB sits in Washington

[object Object]

STRUCTURAL: High regulatory density (score 85) from 8 identified pharma bills. EVIDENTIARY: Three distinct congressional purchasers (C001123, K000389, B001327) across 7 transactions in the last 12 months, but offset by zero corporate insider buys (`get_corporate_insider_signal.total_buys: 0`), zero lobbying spend, and zero federal contracts. Net: Evidentiary congressional interest is countered by a lack of structural political investment and insider conviction.
