The famed short-seller says that he's still short
He admitted that it's been "one of the tougher things in our portfolio this year."
"The books are over caffeinated, if you will," he said.
Einhorn said he doesn't think Green Mountain sells anywhere as near as much coffee as they say.
He pointed out that the CEO wouldn't get into the numbers at a recent analyst conference. "We don't do straight math," the CEO said, according to Einhorn.
"If you're not going to get into this now at an investor conference, when are you going to get into this?"
He predicts that they're going to miss on earnings at some point this year.
The stock was last trading down more than 2.7%. It looks like it moved lower on Einhorn's comments.
Einhorn will be presenting at the inaugural Robin Hood Investment Conference next month along with other big name money managers, including Julian Robertson, Stan Druckenmiller, Daniel Loeb, Bill Ackman, Paul Tudor Jones, etc.
All of the money raised for the conference goes to charity.
