The record on $OMC
Coldpine has parsed 9 disclosed trades in $OMC by 3 members of Congress, drawn from 8 periodic transaction reports dated Oct 31, 2023 through Mar 27, 2026. That is 6 trades from House members and 3 trades from senators, filed 6 by Democrats and 3 by Republicans.
Of the 9 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 116 days: a $OMC 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.
8 of the 9 trades that list an account holder (89%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Rohit Khanna filed the most $OMC purchases (4), and John Boozman the most sales (2).
Activity peaked in 2025 with 4 trades.
Across the 5 purchases Coldpine can price, $OMC moved +3.40% on average between the trade date and the disclosure date, against +5.43% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 60% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
