But I just am afraid to because it’s had such a big move," he added.

Cramer said Plug Power Inc. PLUG is "OK. Andy Marsh [CEO of Plug Power] was on again today. Andy Marsh, I think he must be a regular on the network because I see quite a bit of him. He needs something that is very elusive, that’s called earnings. If he gets them, the stock can still go higher."
