CVS, Walgreens, Rite Aid tumbling after Amazon's Pharmacy launch

• The move by Amazon may have been anticipated for a while, but - at least for now - it wasn't fully priced in to brick-and-mortar pharmacy players.
• CVS (NYSE:CVS) is down 6.4%, Walgreens (NASDAQ:WBA) 10%, and Rite Aid (NYSE:RAD) 9.8% premarket. There's also drug distribution names like Cardinal Health (NYSE:CAH), which is lower by 2.5%, McKesson (NYSE:MCK) down 2.3%, and AmerisourceBergen (NYSE:ABC) off 1.1%.
• And don't forget recently gone-public online drug comparison player GoodRx (NASDAQ:GDRX), down 16.6% premarket.
