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.
48 open-market purchases totalling $1.6M since 2009, against 1 sale. Across 48 scored buys the stock is up 2.5% at ninety days, and 2.1 points ahead of the S&P over the same stretch.
