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.
5 open-market purchases totalling $9.0M since 2013, against 1 sale. Across 5 scored buys the stock is down 6.2% at ninety days, and 7.5 points behind the S&P over the same stretch.
