The record on $MLM

Coldpine has parsed 46 disclosed trades in $MLM by 4 members of Congress, drawn from 27 periodic transaction reports dated Jan 10, 2024 through Aug 10, 2026. All of them came from House members, filed 41 by Democrats and 5 by Republicans.

Of the 44 trades with a known filing lag, every one was reported inside the STOCK Act's 45-day window. The median lag was 25 days. The longest was 40 days: a $MLM sale by Josh Gottheimer dated Apr 9, 2026, disclosed May 19, 2026. How late filing is measured across all of Congress is in the late-filers study.

45 of the 46 trades that list an account holder (98%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Rohit Khanna filed the most $MLM purchases (29), and Rohit Khanna the most sales (7).

Activity peaked in 2025 with 18 trades. The busiest single month was August 2025, when 3 different members disclosed $MLM trades.

Across the 30 purchases Coldpine can price, $MLM moved +1.12% on average between the trade date and the disclosure date, against +1.00% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 50% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
