Why AmerisourceBergen Corp. Fell Dramatically Today

AmerisourceBergen (NYSE: ABC) closed down 10.5% on Thursday after announcing disappointing fiscal third-quarter earnings and reducing its expectations for revenue for the entire fiscal 2017. Fellow drug distributors fell in sympathy, with McKesson (NYSE: MCK) down 2.7% and Cardinal Health (NYSE: CAH) down 2.3%.

Cardinal Health had already fallen dramatically yesterday after announcing its own disappointing guidance for its 2018 fiscal year. And McKesson was down about 4% since reporting earnings last week going into today's further slump.
