Gregory Q. Brown is CEO & Chairman at Motorola Solutions, Inc. (MSI). They have made 69 open-market trades across 2 companies since 2009, most recently 2026-08-21.
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 $2.0M since 2009, against 68 sales. Too few scored purchases to measure a record yet.
