Mark J. Brooks is CIO & VP at CENTENE CORP (CNC). They have made 14 open-market trades across 4 companies since 2010, most recently 2026-01-15.
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.
2 open-market purchases totalling $11.4M since 2010, against 12 sales. Too few scored purchases to measure a record yet.
