Insider selling is negligible relative to market cap and follows a strong earnings report — no bearish read-through. Monitor for any C-suite selling in coming weeks; if CEO/CFO begin selling material amounts, that would warrant attention. For now, the cluster is routine.
Price Chart
Executive Summary
Two MPWR insiders (EVP Maurice Sciammas and Director Jeff Zhou) sold a total of $1.41M in open-market sales over a 7-day window, immediately following a strong Q1 2026 earnings beat and raised guidance. The sales are modest relative to MPWR's $78B market cap (0.0018%), consistent with routine portfolio diversification rather than a bearish signal.
