The record on $ACM

Coldpine has parsed 2 disclosed trades in $ACM by 2 members of Congress, drawn from 2 periodic transaction reports dated Feb 9, 2023 through Mar 27, 2026. That is 1 trade from House members and 1 trade from senators, all filed by Republicans.

Of the 2 trades with a known filing lag, 1 was reported more than 45 days after the trade date, outside the window the STOCK Act sets. The median lag was 69 days. The longest was 116 days: a $ACM sale by Alan Armstrong dated Mar 27, 2026, disclosed Jul 21, 2026. How late filing is measured across all of Congress is in the late-filers study.

1 of the 2 trades that list an account holder (50%) was reported under a spouse, dependent child, or joint account rather than the member directly.

Diana Harshbarger filed the most $ACM purchases (1), and Alan Armstrong the most sales (1).
