Michael Gray is CFO at Mellanox Technologies, Ltd. (MLNX). They have made 9 open-market trades across 4 companies since 2007, most recently 2026-09-16.
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 $29K since 2013, against 8 sales. Too few scored purchases to measure a record yet.
