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.

60 open-market purchases totalling $4.6M since 2006, against 1 sale. Across 14 scored buys the stock is up 4.5% at ninety days, and 3.5 points ahead of the S&P over the same stretch.

Sell Track Record

Filings1

Only 1 decision-sell filing — too few to score

Decision sells only — a first sale after buying the stock, or a sale by a fund or 10% owner. Ordinary sales by officers and directors show no relationship to what the stock does next, so they are counted but not scored.
