Insider buying was dominated by two mega-purchases: William H. Gates III’s Cascade Investment added roughly $241.5 million in Republic Services (RSG), while BlueArc Capital funneled over $164 million into AMG Pantheon Infrastructure (PBLSX), signaling strong conviction in waste management and infrastructure. On the sell side, the largest transaction was a staggering $802.6 million disposal by InnSuites Hospitality Trust (IHT) CEO James F. Wirth, dwarfing all other activity, followed by significant profit-taking in tech and construction with NVIDIA (NVDA) director Mark Stevens selling $410.8 million and Tutor Perini (TPC) director Ronald Tutor offloading $197.7 million. The pattern suggests concentrated bullish bets in defensive sectors, while heavy insider selling in high-flying tech and hospitality names may reflect valuation concerns or personal liquidity needs.
