Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of MicroStrategy (MSTR 3.38%) have plunged today by as much as 13% after the company reported first-quarter earnings.

So what: Revenue in the first quarter added up to $130.2 million, a 6% decline from a year ago. That translated into a loss from continuing operations of $5.2 million, or $0.46 per share. Those figures looked poor relative to consensus estimates, which were calling for $152.4 million in sales and $0.35 per share in profit.

Now what: The company reported a one-time gain of $57.4 million from the sale of Angel.com, but investors are more concerned with continuing operations. Product license revenues were down 24%, while support and services revenues were mostly flat. MicroStrategy has extended its share repurchase program through 2018, and still has $454 million remaining in the authorization.
