Following a report yesterday from the St. Louis Post-Dispatch that Amazon obtained wholesale pharmacy licenses in 12 states, stock prices plunged for a number of pharmaceutical distribution companies, including CVS, Cardinal Health, AmerisourceBergen and McKesson.
Later yesterday afternoon, the Wall Street Journal reported CVS wants to buy health insurer Aetna for $66 billion. That announcement helped mitigate CVS’s stock decline.
AmerisourceBergen and Cardinal Health stocks are down about 10 percent and McKesson stock was down 13 percent this morning.
