William P. Stengel is Director at HOLLY ENERGY PARTNERS LP (HEP). They have made 8 open-market trades across 2 companies since 2008, most recently 2026-05-03.
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 $9K since 2008, against 7 sales. Too few scored purchases to measure a record yet.
