  • What does "buy" mean in QNT activity?

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

  • Is institutional interest in QNT increasing?
