Cramer: Why you can’t short Shake Shack

Just because Shake Shack had a "fabulous" performance, investors should not short the stock because "people love their burgers," CNBC's Jim Cramer said Thursday. (Tweet This)

"They have 68 stores. They can put up 680 stores overnight," Cramer said on "Squawk on the Street."

Cramer made his remarks a day after the burger chain upstart posted quarterly earnings of 4 cents a share on $38 million in revenue. Wall Street expected a loss of 3 cents a share on revenue of $34 million.

"This was a fabulous conference call from the standpoint of 'Guys, we're like this little company but we're going to blow it out.' I always tell these guys [that] if you put one of these in every Starwood property … or in a Hyatt, we would all be so happy."
