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.
34 open-market purchases totalling $1.8M since 2007, against 23 sales. Across 31 scored buys the stock is up 1.7% at ninety days, and 1.0 points ahead of the S&P over the same stretch.
