AI Insider Summary

Patrizio Vinciarelli, Vicor's founder and CEO, runs a single-name VICR record (448 tx) with the recent tape a tight ladder of open-market sales — 6 shares at $288.51, 83 at $287.62, 892 at $286.62 — stepping down through the high $280s, the cadence of plan-based execution at the power-electronics maker's elevated price.

That fine slicing across adjacent prices is the signature of a 10b5-1 plan working an order through the book rather than a discretionary read on the stock. Across 448 transactions the direction is consistently sell-side.

For VICR readers, Vinciarelli is a programmatic founder-seller; the useful datapoint is the high-$280s level his plan is clearing at, with the laddered structure confirming scheduled rather than reactive selling.
