Why Plug Power and FuelCell Energy Stocks Just Crashed -- But Bloom Energy Is Up

Shares of all the major fuel cell stocks plummeted in early-morning trading Thursday, with Plug Power (NASDAQ: PLUG) and FuelCell Energy (NASDAQ: FCEL), for example, both falling roughly 13% before recovering and Bloom Energy (NYSE: BE) dropping 5.4%. Yes, Plug stock is still down 4.7%, and FuelCell is off by 5.5% -- but Bloom Energy, at least, is back in the green -- and up 1.5%. It's no great mystery why fuel cells stocks stumbled this morning -- or why Bloom is recovering faster than most, either.
