WDC Congressional Stock Trades

Coldpine has parsed 13 disclosed trades in $WDC by 2 members of Congress, drawn from 9 periodic transaction reports dated Jan 9, 2023 through Apr 13, 2026. That is 12 trades from House members and 1 trade from senators, filed 12 by Democrats and 1 by Republicans.

Of the 13 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 $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.

12 of the 13 trades that list an account holder (92%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Rohit Khanna filed the most $WDC purchases (9), and Rohit Khanna the most sales (3).

Activity peaked in 2023 with 6 trades.

Across the 10 purchases Coldpine can price, $WDC moved +14.59% on average between the trade date and the disclosure date, against +2.82% 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.
