SNY Congressional Stock Trades

Coldpine has parsed 10 disclosed trades in $SNY by 3 members of Congress, drawn from 10 periodic transaction reports dated Feb 14, 2023 through Mar 30, 2026. That is 9 trades from House members and 1 trade from senators, filed 8 by Democrats and 2 by Republicans.

Of the 10 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 26 days. The longest was 113 days: a $SNY purchase by Alan Armstrong dated Mar 30, 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 $SNY purchases (5), and Rohit Khanna the most sales (3).

Activity peaked in 2025 with 3 trades.

Across the 6 purchases Coldpine can price, $SNY moved -4.47% on average between the trade date and the disclosure date, against +0.84% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 33% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
