Seems like it's quite obvious. Some MMs worked very hard to protect $245 support. If $245 support is broken, it will go to $220 straight.
Overvalued is overvalued regardless it beat 9 cents/share. Based on the current stock price, AMZN has to make 90 cents/share each Q at least. There is no way to make that much money in the next 5 years, may be 10 years, may be forever.
