The record on $WLK

Coldpine has parsed 5 disclosed trades in $WLK by 1 member of Congress, drawn from 1 periodic transaction report dated May 3, 2022 through Aug 12, 2022. All of them came from House members, all filed by Republicans.

Of the 5 trades with a known filing lag, 5 were reported more than 45 days after the trade date, outside the window the STOCK Act sets. The median lag was 819 days. The longest was 920 days: a $WLK purchase by Byron Donalds dated May 3, 2022, disclosed Nov 8, 2024. How late filing is measured across all of Congress is in the late-filers study.

3 of the 5 trades that list an account holder (60%) were reported under a spouse, dependent child, or joint account rather than the member directly.
