You'll forgive me if I don't trust in the judgment of a business plan built on losing money for two or three decades.
They can be a good company, grow to X hundred billion in sales, struggle to ever make money, and that's all perfectly fine - but it doesn't mean they deserve a hyper valuation. Target trades at a mere $38b valuation, and they only generated $8b in net income the past three years.
People say the enterprise cloud market is a Trillion dollar opportunity world wide in the next decade.
A Trillion dollars up for grabs, and Amazon has a healthy lead in the segment.
When you go to an AWS event the thing that stands out is the number of consulting and service companies that offer integration/application services to enterprises based wholly on AWS. I've been to Google Cloud events and its not even in the same ballpark as AWS. The Amazon lead is huge.
I think Amazon is still a good buy.
