David S. Johnson is Director at GALLAGHER ARTHUR J & CO (AJG). They have made 21 open-market trades across 1 company since 2013, most recently 2026-06-01.
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 21 sales. Too few scored purchases to measure a record yet.
