  • What does "buy" mean in QUBT activity?

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