Mark Sullivan III is Director at SAUL CENTERS, INC. (BFS). They have made 5 open-market trades across 3 companies since 2011, most recently 2026-09-14.
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.
0 open-market purchases, against 5 sales. Too few scored purchases to measure a record yet.
