Are you sure about that Reuters? Twitter's stock is up 5% over the last five days. It seems to me that they met the market's expectation for growth. Not many people buy more of a stock after it underperforms their expectations.

This headline is at best misleading -- intended to give the impression that Twitter is performing worse than they are by ignoring the metrics in which they are excelling -- or potentially even just outright wrong.

Remember, this is Wall Street you're talking about, so both things can be true: Twitter can miss analyst's expectations, and the stock can go up because other analysts see an opportunity based on different expectations.

If you're expecting much of what Wall Street (or journalists covering the markets) does to make sense, you're going to have a bad time.

Estimates are analyst estimates, not market expectation. The market can (and often does) expect a company to miss estimates. If they missed by less than expected, the stock usually goes up.
