Insider buying on Dec 9, 2025
On Dec 9, 2025, 53 insiders at 48 companies filed 139 purchases reported on Form 4, worth $58.7M in all, with a median purchase of $26.3K. The largest was IAC Inc., 10% owner of MGM Resorts International (MGM), who reported buying 1,098,748 shares worth $39.9M. Officers accounted for 45 purchases, directors who are not officers for 46, and 10% owners with no board or officer role for 45. Chief executives and chief financial officers filed 33 purchases: Fernandez Henry A, Chairman and CEO, Director of MSCI Inc. (MSCI); Labe James, Chief Executive Officer, Director of TriplePoint Venture Growth BDC Corp. (TPVG); Cohn Charles K., Chief Executive Officer, Director, 10% owner of Nerdy Inc. (NRDY) among others. 11 companies showed cluster buying, two or more insiders buying within 7 days, among them GAM (3 insiders), LUCK (3 insiders), TPVG (2 insiders), SPRU (2 insiders). For 11 insiders of 53, this was the first purchase of that company's stock on our record. That is more than the 122 purchases filed on Dec 8, 2025. A Form 4 is due within two business days of the trade, so most of these purchases were made earlier in the week. Code P also covers shares bought privately from the company, so one large figure can be a negotiated placement rather than buying on the exchange.
