  • What does "buy" mean in MNKD activity?

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

  • Is institutional interest in MNKD increasing?
