The record on $FANG

Coldpine has parsed 3 disclosed trades in $FANG by 2 members of Congress, drawn from 3 periodic transaction reports dated Sep 10, 2024 through Dec 22, 2025. All of them came from House members, filed 2 by Democrats and 1 by Republicans.

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 30 days. The longest was 34 days: a $FANG sale by Greg Landsman dated Sep 10, 2024, disclosed Oct 14, 2024. 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.

Greg Landsman filed the most $FANG sales (2).
