The record on $LRCX
Coldpine has parsed 54 disclosed trades in $LRCX by 14 members of Congress, drawn from 42 periodic transaction reports dated Feb 13, 2023 through Aug 13, 2026. That is 50 trades from House members and 4 trades from senators, filed 26 by Democrats and 28 by Republicans.
Of the 54 trades with a known filing lag, 4 were 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 $LRCX 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.
31 of the 37 trades that list an account holder (84%) were reported under a spouse, dependent child, or joint account rather than the member directly.
Rohit Khanna filed the most $LRCX purchases (12), and David J. Taylor the most sales (12).
Activity peaked in 2026 with 18 trades. The busiest single month was February 2026, when 3 different members disclosed $LRCX trades. In 1 calendar month out of 25 with activity, three or more members bought $LRCX in the same month, the same-direction overlap Coldpine's cluster detector looks for.
Across the 27 purchases Coldpine can price, $LRCX moved +5.46% on average between the trade date and the disclosure date, against +1.11% for the S&P 500 over the same windows. The stock was higher at disclosure than at the trade in 74% of those purchases. That is a record of what already happened, not a forecast. Method: what stocks do before Congress discloses.
