Wall Street gave up on Keurig Green Mountain Thursday with many analysts slashing 12-month price targets nearly in half as the company reported disappointing K-cup sales and provided a weak outlook.

As of Thursday morning, now about 90 percent of the analysts who cover Keurig on Wall Street rate it either "sell" or "hold," according FactSet, an unprecedented negative bias for a well-covered cult stock.

And one notable short seller believes analysts haven't gone far enough in their pessimism, even with the shares losing almost a third of their value in a single day.
