Plug Power -40% on Citron slam, drags down FuelCell, Ballard Power

|About: Plug Power, Inc. (PLUG)|By:, SA News Editor

The collapse in Plug Power (PLUG -40.8%) has pulled down other alternative fuel shares, as investors turned away from FuelCell Energy's (FCEL -21.6%) better than expected Q4 results to focus on Citron Research's report that said PLUG would be fairly valued at 50 cents.

Citron's Andrew Left has since taken to the CNBC airwaves to say PLUG has no unique technology and PLUG's management cannot be trusted.

Ballard Power (BLDP -26.6%), which earned 11% of its revenue last year by supplying the fuel cell stacks that run PLUG’s forklifts, also takes a beating.

Faring better is Capstone Turbine (CPST +7.9%), off earlier five-year highs but still up sharply, as the maker of microturbines has been moving slowly toward profitability.
