Frequently asked questions about MGIC activity

  • What does "buy" mean in MGIC activity?

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