The record on $WAT
Coldpine has parsed 35 disclosed trades in $WAT by 7 members of Congress, drawn from 18 periodic transaction reports dated Aug 12, 2022 through Aug 13, 2026. That is 34 trades from House members and 1 trade from senators, filed 13 by Democrats and 22 by Republicans.
Of the 35 trades with a known filing lag, 17 were reported more than 45 days after the trade date, outside the window the STOCK Act sets. The median lag was 37 days. The longest was 824 days: a $WAT sale by Thomas H Tuberville dated May 3, 2024, disclosed Aug 5, 2026. How late filing is measured across all of Congress is in the late-filers study.
24 of the 31 trades that list an account holder (77%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Byron Donalds filed the most $WAT purchases (12), and Rohit Khanna the most sales (6).
Activity peaked in 2022 with 12 trades. The busiest single month was February 2026, when 3 different members disclosed $WAT trades.
Across the 9 purchases Coldpine can price, $WAT moved +8.34% on average between the trade date and the disclosure date, against +14.65% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 78% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
