Price Chart
Executive Summary
Three MPWR insiders sold a total of $13.71M in open-market transactions over a 7-day window. The largest sale ($12.86M) was by EVP & General Counsel Tseng Saria, representing the bulk of the cluster. At 0.017% of MPWR's $80.2B market cap, the total is trivial relative to company size, and the cluster is dominated by a single non-C-suite executive. The sales are likely liquidity-driven or part of a 10b5-1 plan, not a bearish signal.
