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