Insider buyers were busy on Oct 17, 2024: 25 companies, $124.7 million in open-market purchases all told. The biggest was UPB (Upstream Bio, Inc.), where Access Industries Holdings LLC led about $48 million of buying.
Four of the buys came from a CEO or CFO. Cluster buying (3+ insiders) is running at 34 companies this month. One buy doesn't make a thesis, but it's a good place to start digging.
