Greenlight Capital's Einhorn still short Green Mountain-CNBC

Feb 7 (Reuters) - Fund manager David Einhorn said on Thursday he was keeping a short position on Green Mountain Coffee Roasters, a day after the maker of Keurig single-cup style coffee brewers and K-cups disappointed investors with a weak sales outlook.

Speaking on CNBC, Einhorn said, "we think it's a very poor quality earnings result."

Green Mountain's stock price was down nearly 8 percent in premarket trading on Thursday.

On Wednesday, Green Mountain forecast sales growth for the current quarter slightly below analysts forecasts, pushing the stock down 9 percent.
