Trades from trust-managed members are penalized (× 0.2 multiplier). It’s research, not a recommendation.

The record on $ALC

Coldpine has parsed 4 disclosed trades in $ALC by 4 members of Congress, drawn from 4 periodic transaction reports dated Mar 3, 2025 through Aug 5, 2026. That is 3 trades from House members and 1 trade from senators, filed 2 by Democrats and 2 by Republicans.

Of the 4 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 35 days. The longest was 113 days: a $ALC purchase by Alan Armstrong dated Mar 30, 2026, disclosed Jul 21, 2026. How late filing is measured across all of Congress is in the late-filers study.

2 of the 4 trades that list an account holder (50%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Alan Armstrong filed the most $ALC purchases (1), and Josh Gottheimer the most sales (1).
