Well, the answer is simple https://www.google.com/finance?q=NASDAQ%3APLUG&ei=6jgaU4iCNqKCwAO0aA but PLUG is not the only one with such performance.
It has traded over 125M shares today, more than O/S :-O just amazing and it has risen over 6000% in less than 1 year (but PLUG does make money), maybe one day we could say the same about POET.
cheers
