  • What does "buy" mean in DYN activity?

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

  • Is institutional interest in DYN increasing?
