Let's start with NII Holdings. The provider of mobile communication services in Latin America got clobbered after posting lousy financial results and casting doubts about its future. It saw mobile subscribers decline, and those still around are paying less on average.

"While we are confident that we can improve our business over the long term, our recent disappointing results have significantly affected our liquidity position," the CFO warned in the release, and that's not a good sign.

China Digital TV slumped after announcing fresh financials. Its latest quarter was generally solid, with revenue climbing 12% and profitability more than doubling. However, the leading provider of conditional access systems in the digital television market followed that up with uninspiring guidance, calling for declines -- both sequentially and year-over-year -- in revenue during the current quarter.  

Clean Energy Fuels moved lower after serving up a larger quarterly deficit than Wall Street was targeting. Revenue growth also came a bit light. Clean Energy had beaten analyst estimate in previous quarters, so this was an unwelcome change of pace for the provider of natural gas as a transportation fuel source.

Green Mountain Coffee Roasters slipped after a SunTrust analyst report pointed out how the growth of systemwide sales of K-Cups is decelerating. The silver lining is that we're still eyeing a 29% spike in year-over-year growth, but this figure also includes unlicensed yet perfectly legal K-Cups for which Green Mountain no longer gets a piece of the action. 

Finally we have DreamWorks Animation failing to render results. Turbo was a summertime dud, and the computer-animation giant continues to pay the price by taking a charge to write down the movie about a snail bestowed with the power of speed. Revenue for the fourth quarter fell 23%.
