> Ultimately AMZN's price will be reconciled with it's earnings.
I'm surprised no-one has called you out on this yet. Amazon's price to earnings multiple is currently 223.09 (after the 5% drop). Normal for companies is ~20, maybe 25. Bad companies usually run at 10 or so (usually meaning lots of debt, but no doubts about survival), Great companies run at double that, up to ~50. Amazon's price to earnings is ridiculous.
Nope, Amazon's stock price is purely running on the reputation of the firm itself and of it's manager, Jeff Bezos. It is a huge exception in that regard.
