What's interesting here is that Amazon operates with 0 net profit. So all of its value is really in its stock.
They generate lots of cash, and have negative net working capital. They put all of the profits back into the company. They are extraordinarily opaque regarding performance, strategy and operations, but have made it crystal clear that they don't give a shit about eps. They're really peculiar, and competing against them is a terrible place to be. Having a second console manufacturer who doesn't care about making money should scare the shit out of Sony and Nintendo.
