Is Cactus Stock Still a Buy After a Board Member Shed 10,000 Shares?

Cactus director John A. O'Donnell sold 10,000 shares (36% of his direct stake) on August 5, 2026, at $66.13 per share, slightly above the market close of $65.91. Despite the insider sale, the article notes Cactus has posted record quarterly results with strong revenue growth driven by acquisition activity and robust energy services demand. The key question for investors is whether oil and gas drilling activity remains strong enough to sustain the company's momentum.
