Earnings arent a great way to value a company in 2018. You are predicting future cash flows 5 10 15 20 years away. Shit coal or steel companies may outearn amazon today but a reason exists why amazon is worth 100x more. What they have is much harder to build. 
  
 Same goes for square shopify etc. High end technology is worth more than its sales
