The $7.34M insider selling cluster is trivial relative to MPWR's $79.3B market cap and consistent with routine diversification/vesting patterns. No bearish signal. Monitor for any material change in insider behavior (e.g., a C-suite cluster buy or a sudden increase in sale volume >0.5% of market cap) before adjusting position.
