AMZN is the most Outrageously Overpriced Stock... ...since the DOT COM Bubble of 1998-2000! Use any metric (or metrics) you prefer to measure valuation. This stock is WAAAY overextended. If you're long ya best have stop losses in place. The ride down (when it inevitably comes) is going to be DRAMATIC.
I just wish I had shorted AMZN near its high today (I might get another chance tomorrow though).
