The record on $WMB
Coldpine has parsed 13 disclosed trades in $WMB by 4 members of Congress, drawn from 10 periodic transaction reports dated Dec 26, 2022 through Jun 24, 2026. That is 11 trades from House members and 2 trades from senators, filed 4 by Democrats and 9 by Republicans.
Of the 13 trades with a known filing lag, 3 were reported more than 45 days after the trade date, outside the window the STOCK Act sets. The median lag was 18 days. The longest was 161 days: a $WMB purchase by Jonathan Jackson dated Mar 17, 2025, disclosed Aug 25, 2025. How late filing is measured across all of Congress is in the late-filers study.
12 of the 12 trades that list an account holder (100%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Kevin Hern filed the most $WMB purchases (7), and Alan Armstrong the most sales (2).
Activity peaked in 2025 with 4 trades. The busiest single month was April 2025, when 2 different members disclosed $WMB trades.
Across the 9 purchases Coldpine can price, $WMB moved +0.39% on average between the trade date and the disclosure date, against +4.31% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 33% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
