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.
9 open-market purchases totalling $8.5M since 2006, against 4 sales. Across 8 scored buys the stock is up 3.7% at ninety days, and 3.7 points ahead of the S&P over the same stretch.
