What does "buy" mean in CB activity?
"Buy" means an investor increased their reported position in CB compared to the prior reporting period. This reflects growing exposure to CHUBB LIMITED (CB) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).
