Insider buyers were busy on May 26, 2022: 40 companies, $97.3 million in open-market purchases all told. The biggest was CSQ (CALAMOS STRATEGIC TOTAL RETURN FUND), where MetLife Investment Management, LLC led about $23 million of buying.
C-suite buying: eight companies. Cluster buying (3+ insiders) is running at 212 companies this month. One buy doesn't make a thesis, but it's a good place to start digging.
