Week of Aug 24 – Aug 28, 2026
By Trabud Research Team · SEC Form 4 & insider trading data analysts
Last updated:
Insider buying was led by two massive institutional moves: KC Armada LP, tied to Ernesto Bertarelli, acquired $219 million in MAIR, while Bill Gates' Cascade Investment made three separate purchases totaling roughly $339 million in RSG. On the selling side, CEO James Wirth unloaded over $1 billion in IHT, and large block sales of $590 million in ALH and $385 million combined in AVAH dominated. The activity signals continued conviction in waste management from Gates, while heavy insider liquidation in hospitality and healthcare names suggests profit-taking or repositioning in those sectors.
