  • What does "buy" mean in MGX activity?

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