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

What: Shares of eye-in-the-sky DigitalGlobe (NYSE: DGI) were located at a lower price today as shares slipped as much as 10% after the company reported fourth-quarter earnings.

So what: After yesterday's close, DigitalGlobe released results for the fourth quarter that weren't exactly what investors were hoping for. Revenue of $83.6 million grew 15% from the prior year, but was just shy of projections. Earnings per share of $0.03 didn't measure up either, as Wall Street was looking for $0.05. On the bright side, the company mentioned that it continued to build out its presence in China by signing new contracts with China Mobile (NYSE: CHL), YF International, and Hazens.

Now what: Looking ahead, DigitalGlobe will have to hit the high end of its guidance ranges to appease Wall Street in 2011. The company expects to report revenue of $345 million to $365 million and EPS of $0.20 to $0.40. Analysts had estimated $0.37 in per-share profit on $363 million in revenue. It appears that the news was initially a big disappointment to investors, but after digesting it further they tempered their pessimism. As of this writing, the stock had recovered to a 4.5% loss.
