Ronald J. Kramer is CEO & Chairman at GRIFFON CORP (GFF). They have made 25 open-market trades across 4 companies since 2006, most recently 2026-08-05.
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.
12 open-market purchases totalling $7.4M since 2007, against 13 sales. Across 12 scored buys the stock is up 10.2% at ninety days, and 10.0 points ahead of the S&P over the same stretch.
