I've been meaning to ask this for a while after the repeated mentions of lack of profitability. Have you checked the records to see how many years Amazon was unprofitable before beginning to show positives? I recall not having purchased shares of Amazon back in 1999 because they were trading at a very high price and had yet to show profitability. Your answer might be that they at least had impressive revenues, but I think there is some relevance to the issue that a start-up company in a disruptive industry does not expect to show profit for a number of years in most cases.
