Insider buyers were busy on Jun 4, 2025: 40 companies, $510.2 million in open-market purchases all told. At the top: TKO, $500 million bought, with Silver Lake West VoteCo, L.L.C. as the largest buyer.
Ten of the buys came from a CEO or CFO. Cluster buying (3+ insiders) is running at 107 companies this month. One buy doesn't make a thesis, but it's a good place to start digging.
