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.
8 open-market purchases totalling $600K since 2013, never a sale. Across 6 scored buys the stock is down 16.5% at ninety days, and 22.6 points behind the S&P over the same stretch.
