Public record / Tickers / MPWR

MPWR — MONOLITHIC POWER SYSTEMS, INC.

Both disclosure regimes on one name: who in Congress filed about MPWR, which institutions reported holding it. Each section keeps its own clock — congressional trades on the 45-day PTR clock, 13F holdings as quarter-end snapshots.
