The record on $COHR
Coldpine has parsed 14 disclosed trades in $COHR by 4 members of Congress, drawn from 11 periodic transaction reports dated Apr 10, 2023 through Aug 3, 2026. That is 10 trades from House members and 4 trades from senators, filed 9 by Democrats and 5 by Republicans.
Of the 14 trades with a known filing lag, every one was reported inside the STOCK Act's 45-day window. The median lag was 26 days. The longest was 35 days: a $COHR purchase by Michael T. McCaul dated May 6, 2026, disclosed Jun 10, 2026. How late filing is measured across all of Congress is in the late-filers study.
12 of the 14 trades that list an account holder (86%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Rohit Khanna filed the most $COHR purchases (4), and Rohit Khanna the most sales (4).
Activity peaked in 2026 with 9 trades. The busiest single month was June 2026, when 2 different members disclosed $COHR trades.
Across the 7 purchases Coldpine can price, $COHR moved +8.87% on average between the trade date and the disclosure date, against +1.44% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 71% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
