MGM Congressional Stock Trades

Coldpine has parsed 13 disclosed trades in $MGM by 3 members of Congress, drawn from 12 periodic transaction reports dated Jul 28, 2023 through Sep 25, 2026. That is 12 trades from House members and 1 trade from senators, filed 12 by Democrats and 1 by Republicans.

Of the 13 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 20 days. The longest was 116 days: a $MGM purchase by Alan Armstrong dated Mar 27, 2026, disclosed Jul 21, 2026. How late filing is measured across all of Congress is in the late-filers study.

11 of the 12 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 $MGM purchases (9), and Rohit Khanna the most sales (2).

Activity peaked in 2025 with 7 trades. The busiest single month was March 2025, when 2 different members disclosed $MGM trades.

Across the 10 purchases Coldpine can price, $MGM moved -2.18% on average between the trade date and the disclosure date, against +0.59% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 30% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
