John C. Miller is Director at DENNYS CORP (DENN). They have made 22 open-market trades across 2 companies since 2000, most recently 2026-05-29.
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 $543K since 2011, against 19 sales. Too few scored purchases to measure a record yet.
