The record on $WTM
Coldpine has parsed 16 disclosed trades in $WTM by 2 members of Congress, drawn from 11 periodic transaction reports dated Dec 20, 2023 through Jun 18, 2026. All of them came from House members, all filed by Republicans.
Of the 16 trades with a known filing lag, every one was reported inside the STOCK Act's 45-day window. The median lag was 25 days. The longest was 40 days: a $WTM sale by Michael T. McCaul dated May 1, 2026, disclosed Jun 10, 2026. How late filing is measured across all of Congress is in the late-filers study.
12 of the 16 trades that list an account holder (75%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Michael T. McCaul filed the most $WTM purchases (5), and Michael T. McCaul the most sales (10).
Activity peaked in 2024 with 8 trades.
Across the 6 purchases Coldpine can price, $WTM moved -0.17% on average between the trade date and the disclosure date, against +1.60% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 17% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
