COO Congressional Stock Trades

Coldpine has parsed 39 disclosed trades in $COO by 3 members of Congress, drawn from 16 periodic transaction reports dated Oct 10, 2023 through Sep 17, 2026. That is 38 trades from House members and 1 trade from senators, filed 37 by Democrats and 2 by Republicans.

Of the 39 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 22 days. The longest was 116 days: a $COO 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.

37 of the 38 trades that list an account holder (97%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Rohit Khanna filed the most $COO purchases (33), and Rohit Khanna the most sales (4).

Activity peaked in 2025 with 18 trades. The busiest single month was May 2025, when 2 different members disclosed $COO trades.

Across the 34 purchases Coldpine can price, $COO moved -0.68% on average between the trade date and the disclosure date, against +2.00% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 65% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
