An rally that has already yielded huge gains for fuel cell and other alternative energy stocks is now propelling smart grid/wind turbine maker American Superconductor (AMSC +12.8%) higher.

Last month, AMSC rallied on an FQ3 beat and a favorable legal ruling in its long-running battle against ex-customer Sinovel. 9% of the float was shorted as of Feb. 14.
