Bruce Campbell is Chief Dev Dist & Legal Officer at Discovery, Inc. (DISCA). They have made 13 open-market trades across 3 companies since 2009, most recently 2026-10-06.
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.
3 open-market purchases totalling $23K since 2009, against 10 sales. Too few scored purchases to measure a record yet.
