Director clusters buying at increasing volume (now $576K in 7 days vs $740K in prior 30 days) is the strongest insider signal per academic literature. The repeat buying by directors who have no liquidity-driven selling agenda signals conviction. Traders should watch for potential M&A or reserve update catalysts in coming weeks given the concentrated buying pattern.
Price Chart
Executive Summary
Three Granite Ridge directors made open-market purchases totaling $576K over the past week, with director Perry Griffin alone buying $549K worth at $5.49/share. This is the second cluster of insider buying in two weeks, reinforcing a bullish signal from directors who lack the diversification incentives of C-suite insiders.
