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.
5 open-market purchases totalling $300K since 2017, against 33 sales. Across 5 scored buys the stock is up 21.4% at ninety days, and 18.2 points ahead of the S&P over the same stretch.
