The idea that Amazon isn't profitable is laughable at best. Examine what they're doing. If they stopped constantly creating new business divisions they'd be super profitable. They continue to invest in new businesses, though, so on the whole they're "unprofitable" on a cashflow basis. On a sales basis though? Immensely profitable.
Just because Amazon has ideas about how to reinvest doesn't mean they're only breaking even on their sales or selling at a loss. Starting new businesses every year costs money. Amazon might not have balance sheet profits but the company continues to grow. How could they do that if they were making a loss on everything? They aren't issuing anywhere NEAR enough shares to keep the loss-leader scheme going on investor money: https://ycharts.com/companies/AMZN/shares_outstanding
