Why AbbVie and Amgen Are Moving Lower Today
Shares of the immunology juggernaut AbbVie (NYSE: ABBV) were down by 4% on sky-high volume as of 11 a.m. ET Thursday. The big loss came after Coherus Biosciences announced a partnership with billionaire Mark Cuban's pharmaceuticals start-up -- known as the Mark Cuban Cost Plus Drug Company -- to sell a biosimilar (a generic biologic) version of AbbVie's flagship anti-inflammatory medication, Humira, at an 85% discount. Coherus' biosimilar will be branded as Yusimry.
