  • What does "buy" mean in SUPN activity?

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