What does "buy" mean in NKTR activity?
"Buy" means an investor increased their reported position in NKTR compared to the prior reporting period. This reflects growing exposure to NEKTAR THERAPEUTICS (NKTR) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).
Is institutional interest in NKTR increasing?
