The record on $AMGN
Coldpine has parsed 58 disclosed trades in $AMGN by 16 members of Congress, drawn from 42 periodic transaction reports dated Dec 9, 2022 through Sep 22, 2026. That is 55 trades from House members and 3 trades from senators, filed 35 by Democrats and 23 by Republicans.
Of the 58 trades with a known filing lag, 4 were reported more than 45 days after the trade date, outside the window the STOCK Act sets. The median lag was 23 days. The longest was 477 days: a $AMGN sale by Thomas H Tuberville dated Apr 15, 2025, disclosed Aug 5, 2026. How late filing is measured across all of Congress is in the late-filers study.
41 of the 48 trades that list an account holder (85%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Rohit Khanna filed the most $AMGN purchases (18), and Rohit Khanna the most sales (9).
Activity peaked in 2026 with 18 trades. The busiest single month was September 2025, when 3 different members disclosed $AMGN trades.
Across the 33 purchases Coldpine can price, $AMGN moved -0.60% on average between the trade date and the disclosure date, against +2.66% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 42% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
