Dhiren R. Fonseca is Director at ALASKA AIR GROUP, INC. (ALK). They have made 7 open-market trades across 4 companies since 2015, most recently 2026-09-25.
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.
0 open-market purchases, against 7 sales. Too few scored purchases to measure a record yet.
