Boston Scientific Corp. is 10% at CYBERONICS INC (CYBX). They have made 7 open-market trades across 4 companies since 2005, most recently 2021-07-13.
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.
1 open-market purchase totalling $5.4M since 2005, against 6 sales. Too few scored purchases to measure a record yet.
