40 companies had corporate insiders buying in open-market trades in filings dated Dec 7, 2021, about $31 million combined. CLR topped the list with roughly $5.1 million, led by Hamm Harold.
Cluster buying (3+ insiders) is running at 150 companies this month. CEOs and CFOs show up 7 times in today's list. One buy doesn't make a thesis, but it's a good place to start digging.
