BXP Congressional Stock Trades

Coldpine has parsed 17 disclosed trades in $BXP by 3 members of Congress, drawn from 11 periodic transaction reports dated Jan 9, 2023 through Mar 27, 2026. That is 16 trades from House members and 1 trade from senators, filed 15 by Democrats and 2 by Republicans.

Of the 17 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 28 days. The longest was 116 days: a $BXP 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.

15 of the 16 trades that list an account holder (94%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Rohit Khanna filed the most $BXP purchases (10), and Rohit Khanna the most sales (5).

Activity peaked in 2025 with 8 trades.

Across the 11 purchases Coldpine can price, $BXP moved +5.60% on average between the trade date and the disclosure date, against +1.95% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 64% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
