MU Congressional Stock Trades

Coldpine has parsed 111 disclosed trades in $MU by 10 members of Congress, drawn from 32 periodic transaction reports dated Jan 8, 2023 through Jul 8, 2026. That is 106 trades from House members and 5 trades from senators, filed 106 by Democrats and 5 by Republicans.

Of the 111 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 20 days. The longest was 116 days: a $MU 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.

105 of the 108 trades that list an account holder (97%) were reported under a spouse, dependent child, or joint account rather than the member directly.

Rohit Khanna filed the most $MU purchases (52), and Rohit Khanna the most sales (41).

Activity peaked in 2025 with 51 trades. The busiest single month was June 2026, when 3 different members disclosed $MU trades. In 1 calendar month out of 27 with activity, three or more members bought $MU in the same month, the same-direction overlap Coldpine's cluster detector looks for.

Across the 60 purchases Coldpine can price, $MU moved +2.44% on average between the trade date and the disclosure date, against +1.18% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 48% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
