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.
11 open-market purchases totalling $3.6M since 2007, against 12 sales. Across 11 scored buys the stock is up 17.3% at ninety days, and 11.4 points ahead of the S&P over the same stretch.
