The record on $MPWR
Coldpine has parsed 24 disclosed trades in $MPWR by 5 members of Congress, drawn from 18 periodic transaction reports dated Dec 7, 2022 through Jul 27, 2026. That is 20 trades from House members and 4 trades from senators, filed 15 by Democrats and 9 by Republicans.
Of the 24 trades with a known filing lag, 3 were reported more than 45 days after the trade date, outside the window the STOCK Act sets. The median lag was 26 days. The longest was 824 days: a $MPWR 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.
20 of the 22 trades that list an account holder (91%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Rohit Khanna filed the most $MPWR purchases (9), and Rohit Khanna the most sales (6).
Activity peaked in 2024 with 9 trades. The busiest single month was June 2026, when 2 different members disclosed $MPWR trades.
Across the 15 purchases Coldpine can price, $MPWR moved +15.28% on average between the trade date and the disclosure date, against +7.85% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 53% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
