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.
20 open-market purchases totalling $12.0M since 2011, never a sale. Too few scored purchases to measure a record yet.
