John Foster is 10% Owner at Alphatec Holdings, Inc. (ATEC). They have made 9 open-market trades across 3 companies since 2006, most recently 2016-11-30.
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.
6 open-market purchases totalling $20.7M since 2006, against 3 sales. Too few scored purchases to measure a record yet.
