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