MPWR

Monolithic Power Systems (MPWR), an Information Technology sector security, has attracted disclosed trading activity from five members of Congress across 13 total transactions spanning from December 2022 through February 2026, reflecting a net buying posture of nine purchases against four sales. The most active disclosers by trade count include Ro Khanna, Tommy Tuberville, Markwayne Mullin, and Rob Bresnahan, though no bipartisan co-trading clusters have been recorded for this ticker in the public disclosure data. In the cross-branch public record, four executive-branch officials have independently disclosed 13 transactions in the same security, with the closest congressional and executive purchases falling three days apart — a sequence observable in separate filings within the 90-day proximity window. Congressional interest in MPWR remains relatively limited in breadth at five members, though the buy-side tilt and continued activity through early 2026 characterize the current disclosed record.
