Martin F. Roper is President at BOSTON BEER CO INC (SAM). They have made 257 open-market trades across 2 companies since 2006, most recently 2025-03-04.
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 $1.5M since 2008, against 256 sales. Too few scored purchases to measure a record yet.
