The record on $MMC
Coldpine has parsed 55 disclosed trades in $MMC by 5 members of Congress, drawn from 31 periodic transaction reports dated Jan 4, 2023 through Sep 23, 2026. All of them came from House members, filed 48 by Democrats and 7 by Republicans.
Of the 54 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 140 days: a $MMC purchase by Rick Larsen dated Jan 6, 2023, disclosed May 26, 2023. How late filing is measured across all of Congress is in the late-filers study.
52 of the 54 trades that list an account holder (96%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Rohit Khanna filed the most $MMC purchases (29), and Rohit Khanna the most sales (17).
Activity peaked in 2023 with 19 trades. The busiest single month was May 2025, when 2 different members disclosed $MMC trades.
Across the 30 purchases Coldpine can price, $MMC moved +0.26% on average between the trade date and the disclosure date, against +1.44% 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.
