"We rate PLUG POWER INC (PLUG) a SELL. This is driven by a few notable weaknesses, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. The company's weaknesses can be seen in multiple areas, such as its weak operating cash flow and generally disappointing historical performance in the stock itself."
