AI Insider Summary

Two decades of pure selling define Maurice Sciammas's Form 4 history at Monolithic Power Systems — 928 transactions since 2006, 2,053,072 shares sold, zero bought. His most recent trading day, July 15, 2026, shows an unusually granular laddered pattern: 18 separate sale tranches ranging from 50 to 5,640 shares, priced from $1,314.03 up to $1,405.71 — a single session capturing roughly a 7% price range as the stock moved. Read across his last three months of activity, the sale prices trace a broader decline: $1,571-$1,585 in mid-May 2026, down to $1,533.95 by June 1, and further to $1,314-$1,405 by mid-July — MPWR shares fell roughly 15-17% over that span. A 12,472-share gift transfer on May 29, 2026 stands apart from the routine sale program.

A single session laddered across 18 price tiers

July 15, 2026 shows the clearest example of a systematic, price-laddered sale execution: 18 separate tranches ranging from 50 to 5,640 shares, priced continuously from $1,314.03 up to $1,405.71 — a roughly 7% range captured within a single trading day as the stock moved through the session. This granular tranche structure is the signature of an algorithmic or broker-executed sale designed to capture a moving price rather than a single lump-sum transaction.
