USA Insider Trading Pulse — June 29, 2026
Today's insider trading pulse reveals a pronounced divergence between heavy insider selling at Chinese ADRs (Alibaba, Sea Ltd, UP Fintech) and significant insider buying at deeply discounted micro-cap and special situation names (CalciMedica, Hammer Technology, MODIV Industrial). The Alibaba CFO's $2.13M sale stands out as the largest single insider disposition, while Hammer Technology's CEO deployed $2.68M at $0.26/share, signaling extreme conviction in a turnaround. A notable cluster of option exercises at Brazilian Electric Power Co (Eletrobras) suggests management is monetizing long-term equity grants, likely tied to the company's privatization and restructuring. TTM Technologies saw coordinated selling by five executives under 10b5-1 plans, indicating pre-planned portfolio diversification rather than a negative signal. The overall theme is one of insider caution at larger-cap growth names versus opportunistic buying at distressed levels, with 10b5-1 plans providing cover for much of the selling activity.
