But amazon has been telling "screw you" to investors ever since it went public in 1998. How long is their long term plan? The only reason investors are tolerating this is because the stock price has gone up as apparently there is no shortage of people who think that huge profits are just around the corner.
It's not quite that simple - there are profits at Amazon - they are just in certain divisions that are then funding the money-losing divisions.
Amazon takes a profitable business (remember when they sold BOOKS?) and makes it profitable, but takes those profits to invest in something crazy (like NOT BOOKS, or Kindle, or Prime) and then those divisions get profitable and the cycle repeats.
If Amazon ever wanted to stop growing as a company it could kill off the non-profitable divisions and show a dividend in short order. This is why the stock has value. Perhaps too much, but the entire market is in a bubble, so it's hard to dice which part of the stock price is which. In some ways stock prices are relative with an absurd floor.
Investors who have no appetite for such companies can - :gasp: - invest in other companies.
