No chance AMZN and WMT have higher gross margins than AAPL does. Amazon's e-commerce business has actually lost money the past two quarters; but AWS generates healthy profits and growth.seems like Gross margin would be a better thing to look at. quick searches, so could be wrong.
apple is 20-25% looks like
amazon ~ 40%!! holy shit.
wellsfargo: ~ 20-25%
oil companies ~ 8 to 10% avg- I am surprised they did not make the list with the volumes they have though.
