The record on $HALO

Coldpine has parsed 3 disclosed trades in $HALO by 2 members of Congress, drawn from 3 periodic transaction reports dated Dec 6, 2022 through Mar 24, 2025. All of them came from House members, all filed by Democrats.

Of the 3 trades with a known filing lag, every one was reported inside the STOCK Act's 45-day window. The median lag was 24 days. The longest was 38 days: a $HALO sale by Josh Gottheimer dated Dec 6, 2022, disclosed Jan 13, 2023. How late filing is measured across all of Congress is in the late-filers study.

2 of the 2 trades that list an account holder (100%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Josh Gottheimer filed the most $HALO sales (2).
