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.
13 open-market purchases totalling $462K since 2019, against 1 sale. Across 13 scored buys the stock is down 20.1% at ninety days, and 22.3 points behind the S&P over the same stretch.

Counted per filing, not per execution lot — a purchase filled in several tranches is one decision.
