Congressional Activity
LAM RESEARCH CORPORATION CMN
ARIA INTELLIGENCE BRIEF

Lam Research (Information Technology) has drawn disclosed trading activity from 22 members of Congress across 72 total transactions spanning November 2022 through June 2026, with the balance tilting toward sales — 41 against 31 purchases — reflecting a net selling posture across the disclosure record. The most active disclosers by transaction count are David Taylor, Ro Khanna, Markwayne Mullin, and Kathy Manning, and the record includes one bipartisan co-trading cluster in which members from both parties disclosed transactions in the name. In the executive-branch disclosure record, 13 officials have separately filed 20 transactions in the same security, with the closest congressional and executive purchases falling zero days apart — a sequence observed in independent public filings.

Signal Congress surfaces public disclosure data. This is not investment advice and does not imply wrongdoing.
