The record on $STM

Coldpine has parsed 10 disclosed trades in $STM by 3 members of Congress, drawn from 7 periodic transaction reports dated Feb 24, 2023 through Mar 30, 2026. That is 9 trades from House members and 1 trade from senators, filed 5 by Democrats and 5 by Republicans.

Of the 10 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 73 days. The longest was 623 days: a $STM purchase by Byron Donalds dated Feb 24, 2023, disclosed Nov 8, 2024. How late filing is measured across all of Congress is in the late-filers study.

7 of the 10 trades that list an account holder (70%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Rohit Khanna filed the most $STM purchases (4), and Byron Donalds the most sales (2).

Activity peaked in 2023 with 6 trades. The busiest single month was October 2023, when 2 different members disclosed $STM trades.

Across the 7 purchases Coldpine can price, $STM moved +5.52% on average between the trade date and the disclosure date, against +20.63% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 43% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
