  • What does "buy" mean in BLLN activity?

    "Buy" means an investor increased their reported position in BLLN compared to the prior reporting period. This reflects growing exposure to BillionToOne, Inc. (BLLN) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).
