Amazon had a crazy long term focus: http://www.fool.com/investing/general/2013/11/04/why-amazon-... . Their lack of a profit seems to be intentional, in that Jeff Bezos is willing to sacrifice short-term profit for a long-term vision. So the traders are actually making a rational choice here.
Plus it's a really weird comparison. One of the oldest, and by far the most successful online marketplaces with long term vision vs. a cloud storage startup who is competing against some major players (Google, Dropbox) and is burning through money. I'm unsure of Box too, I just don't see how Amazon is a reasonable comparison.
I didn't mean to compare Amazon to Box. I mentioned Amazon to point out another tech company that is a darling of Wall Street - despite unprofitability (generally).
