ZBH Congressional Stock Trades

Coldpine has parsed 61 disclosed trades in $ZBH by 4 members of Congress, drawn from 20 periodic transaction reports dated Aug 29, 2023 through Sep 14, 2026. That is 60 trades from House members and 1 trade from senators, filed 59 by Democrats and 2 by Republicans.

Of the 60 trades with a known filing lag, 2 were reported more than 45 days after the trade date, outside the window the STOCK Act sets. The median lag was 26 days. The longest was 116 days: a $ZBH 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.

59 of the 60 trades that list an account holder (98%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Rohit Khanna filed the most $ZBH purchases (40), and Rohit Khanna the most sales (18).

Activity peaked in 2023 with 23 trades. The busiest single month was May 2025, when 2 different members disclosed $ZBH trades.

Across the 40 purchases Coldpine can price, $ZBH moved -0.17% on average between the trade date and the disclosure date, against +3.15% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 45% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
