WDC Congressional Stock Trades

Coldpine has parsed 14 disclosed trades in $WDC by 2 members of Congress, drawn from 10 periodic transaction reports dated Jan 9, 2023 through Sep 25, 2026. That is 13 trades from House members and 1 trade from senators, filed 13 by Democrats and 1 by Republicans.

Of the 14 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 116 days: a $WDC 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.

13 of the 14 trades that list an account holder (93%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Rohit Khanna filed the most $WDC purchases (10), and Rohit Khanna the most sales (3).

Activity peaked in 2023 with 6 trades.

Across the 11 purchases Coldpine can price, $WDC moved +12.24% on average between the trade date and the disclosure date, against +2.63% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 55% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
