I'd just like to point out, their loss was pretty much solely the result of a $158 million dollar compensation expense. "Net loss – GAAP net loss was $145 million for the second quarter of 2014 compared to a net loss of $42 million in the same period last year. Twitter's GAAP net loss included $158 million of stock-based compensation expense." Thats probably why the "loss" is mostly irrelevant to the stock price increasing. Depending of course on what you think that business action means for the company. As well, growth is accelerating (increasing at the margins [i.e. The derivative of growth is increasing]). ... Make of it what you will, that's the magic (investing) part.
