Robert L. Harris II is Chairman at ACACIA RESEARCH CORP (ACTG). They have made 25 open-market trades across 3 companies since 2008, most recently 2026-05-28.
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.
14 open-market purchases totalling $1.5M since 2008, against 11 sales. Across 14 scored buys the stock is down 8.8% at ninety days, and 10.6 points behind the S&P over the same stretch.
