Frequently asked questions about CPRX activity

  • What does "buy" mean in CPRX activity?

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