Insider buying on Oct 24, 2025

On Oct 24, 2025, 18 insiders at 17 companies filed 35 purchases reported on Form 4, worth $113.5M in all, with a median purchase of $5.4K. The largest was Platinum International Investment Holding RSC Ltd, 10% owner of CIK 1959604, who reported buying 5,540,093 shares worth $80.0M. Officers accounted for 8 purchases, directors who are not officers for 20, and 10% owners with no board or officer role for 3. Chief executives and chief financial officers filed 2 purchases: Meli Ali, President and CEO, Director, 10% owner of MONIX; Quinn William P., President, CEO and CFO, Director of Bolt Biotherapeutics, Inc. (BOLT). 1 company showed cluster buying, two or more insiders buying within 7 days: BOLT (2 insiders). For 2 insiders of 18, this was the first purchase of that company's stock on our record. That is more than the 33 purchases filed on Oct 23, 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.
