USA Insider Trading Pulse — August 27, 2026
The August 27, 2026 insider trading pulse reveals a pronounced bearish tilt, with 15 sell transactions from C-suite executives at high-growth and established firms, including Tempus AI, Sea Ltd, DoorDash, and Twist Bioscience, many executed under 10b5-1 plans. The most concentrated selling occurred at Sea Ltd, where the CEO, COO, and two other senior leaders collectively sold over $5 million in shares, signaling potential caution despite the company's growth narrative. On the positive side, Comscore's CEO made a $105,000 open-market purchase, a rare bullish signal for a struggling firm, while Horizon Kinetics made token buys in Texas Pacific Land and RENN Fund. The data shows a clear divergence: insiders at cash-flow-rich companies like Church & Dwight and Service Corp International are monetizing options or reducing large positions, while insiders at smaller, distressed firms are buying. No forward-looking guidance changes or major capital allocation shifts were detected in this batch, but the sheer volume of insider selling at key names warrants a defensive posture in growth and tech sectors.
