The record on $DGX
Coldpine has parsed 17 disclosed trades in $DGX by 4 members of Congress, drawn from 11 periodic transaction reports dated Sep 6, 2023 through Sep 4, 2026. That is 15 trades from House members and 2 trades from senators, filed 13 by Democrats and 4 by Republicans.
Of the 17 trades with a known filing lag, 3 were reported more than 45 days after the trade date, outside the window the STOCK Act sets. The median lag was 30 days. The longest was 521 days: a $DGX sale by Carol Devine Miller dated Mar 10, 2025, disclosed Aug 13, 2026. How late filing is measured across all of Congress is in the late-filers study.
15 of the 17 trades that list an account holder (88%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Rohit Khanna filed the most $DGX purchases (8), and Rohit Khanna the most sales (4).
Activity peaked in 2024 with 7 trades.
Across the 10 purchases Coldpine can price, $DGX moved +1.96% on average between the trade date and the disclosure date, against +4.94% 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.
