Looks rational to me.
Maybe AMZN needs to be cut in half.
The risk from competition is far greater for FB than AMZN, that's why the market is willing to give AMZN a higher P/E.
AMZN forward and PE is huge.
Wouldn't touch amazon stock.
AMZN has a lot of competition. They sell with little margin.
If AMZN ever tried to raise prices and increase their margin, people will buy locally.
Sales taxes are being applied to amzn purchases which reduces their price advantage.
Yep FB forward PE is still much lower than AMZN's. Poor shorts.
