LYB Congressional Stock Trades

Coldpine has parsed 16 disclosed trades in $LYB by 4 members of Congress, drawn from 15 periodic transaction reports dated Feb 14, 2023 through Apr 13, 2026. That is 15 trades from House members and 1 trade from senators, filed 14 by Democrats and 2 by Republicans.

Of the 16 trades with a known filing lag, 1 was reported more than 45 days after the trade date, outside the window the STOCK Act sets. The median lag was 23 days. The longest was 116 days: a $LYB purchase by Alan Armstrong dated Mar 27, 2026, disclosed Jul 21, 2026. How late filing is measured across all of Congress is in the late-filers study.

14 of the 15 trades that list an account holder (93%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Rohit Khanna filed the most $LYB purchases (10), and Rohit Khanna the most sales (3).

Activity peaked in 2025 with 8 trades. The busiest single month was May 2025, when 2 different members disclosed $LYB trades.

Across the 12 purchases Coldpine can price, $LYB moved -0.05% on average between the trade date and the disclosure date, against +3.41% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 50% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
