  • What does "buy" mean in MAGN activity?

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