Why Plug Power, Bloom Energy, and Enphase Energy Stocks Just Crashed

The stock market is melting down, with the Dow Jones Industrial Average facing its worst monthly performance since March and the S&P 500 off 1.7% -- and renewable energy stocks are taking it on the chin. In 11:55 a.m. EDT trading, shares of hydrogen fuel cell company Bloom Energy (NYSE: BE) fell a staggering 14%, while rival Plug Power (NASDAQ: PLUG) sank 5%. Elsewhere in the sector, solar microinverter maker Enphase Energy (NASDAQ: ENPH) racked up a 6.2% loss -- and I worry that Bloom may be the cause of it all.
