Never get upset about share prices. If you know they are wrong put your money where your mouth is and hope that you can stay solvent longer than the market stays irrational in this case.

I haven't studied the details of these but if I had to guess the Amazon side probably is riskier but has a larger potential upside while Apple may have peaked but even if they have their is still a decade or more of good profits to expect. I would look for something less high profile with a bigger potential upside than either.
