Quick quiz. What is common to Suzlon, Moser Baer, Indo Solar, Websol Energy systems and Orient Green Power?

Valuations were more on growth stories than through an hard nosed DCF spreadsheet. But now, they trade at record lows(like other stocks but what is different is the pressing fundamental concerns in each case). Is this a bubble finally bursting, or are investors panicking?
