CapitolRadar analysis
47 tracked AMGN trades split 27 buys to 20 sells
Amgen Inc., classified in Healthcare / Drug Manufacturers - General, recorded 47 tracked trades by six distinct traders from November 7, 2019 through August 12, 2026. The activity comprised 27 buys and 20 sells, so buys represented the larger side of the disclosed trade count. Even so, six traders constitute a small sample, and trade counts alone do not establish the size, conviction, timing rationale or broader portfolio context of any transaction.
8 recent quarters produced only 10 trades
The listed quarterly data show sparse recent activity. There was one trade in each of 2024 Q3, 2024 Q4, 2025 Q1, 2025 Q3, 2025 Q4, 2026 Q2 and 2026 Q3, plus three trades in 2025 Q2. Seven of those 10 trades were buys: one each in 2024 Q3, 2024 Q4, 2025 Q3, 2025 Q4 and 2026 Q2, and two in 2025 Q2. The single trades in 2025 Q1 and 2026 Q3 were not buys. These quarterly observations are small samples, making short-term comparisons especially sensitive to individual disclosures.
25 of 27 buys came from three named buyers
Ro Khanna accounted for 11 buys, most recently on June 2, 2026. Josh Gottheimer recorded eight buys, most recently on April 12, 2023, while Marjorie Taylor Greene recorded six, most recently on October 24, 2025. Tommy Tuberville added two buys, last dated October 6, 2022. Together, those four named buyers account for all 27 tracked buys. Among these buyers, two also bought each of FCX, PANW, ADI and GOOGL; one also bought MET, and one also bought NOW. These overlaps indicate other disclosed purchases, not a motive for buying AMGN.
Congressional disclosures can appear up to 45 days after a transaction, so reported activity may lag the trade date. Transaction amount ranges were not provided here; when amounts are disclosed as ranges, any value derived from them is an estimate rather than an exact trade size.
