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.
7 open-market purchases totalling $378K since 2006, against 3 sales. Across 6 scored buys the stock is up 3.6% at ninety days, and 2.1 points ahead of the S&P over the same stretch.
