The record on $MMM
Coldpine has parsed 29 disclosed trades in $MMM by 9 members of Congress, drawn from 24 periodic transaction reports dated Mar 14, 2023 through Apr 28, 2026. That is 27 trades from House members and 2 trades from senators, filed 23 by Democrats and 6 by Republicans.
Of the 29 trades with a known filing lag, 2 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 395 days: a $MMM purchase by Julie Johnson dated Mar 15, 2024, disclosed Apr 14, 2025. How late filing is measured across all of Congress is in the late-filers study.
24 of the 26 trades that list an account holder (92%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Rohit Khanna filed the most $MMM purchases (12), and Rohit Khanna the most sales (5).
Activity peaked in 2023 with 11 trades. The busiest single month was April 2026, when 2 different members disclosed $MMM trades.
Across the 18 purchases Coldpine can price, $MMM moved +5.64% on average between the trade date and the disclosure date, against +2.86% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 72% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
