Jeffrey Westphal is 10% Owner at Vertex, Inc. (VERX). They have made 9 open-market trades across 1 company since 2024, most recently 2026-02-17.
Unrated. We grade insiders only on stock they chose to buy on the open market. Grants, option exercises and vesting say nothing about timing, so they don't count — which is why someone can file often and still have no grade. It isn't a bad sign: unrated buys beat every graded tier below A.
1 open-market purchase totalling $5.1M since 2026, against 8 sales. Too few scored purchases to measure a record yet.
