The record on $WST
Coldpine has parsed 21 disclosed trades in $WST by 2 members of Congress, drawn from 17 periodic transaction reports dated Jan 9, 2023 through Jun 2, 2026. All of them came from House members, all filed by Democrats.
Of the 21 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 34 days: a $WST sale by Rohit Khanna dated Jun 2, 2026, disclosed Jul 6, 2026. How late filing is measured across all of Congress is in the late-filers study.
20 of the 20 trades that list an account holder (100%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Rohit Khanna filed the most $WST purchases (15), and Rohit Khanna the most sales (3).
Activity peaked in 2024 with 10 trades. The busiest single month was February 2025, when 2 different members disclosed $WST trades.
Across the 16 purchases Coldpine can price, $WST moved +2.99% on average between the trade date and the disclosure date, against +2.71% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 63% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
