I think FCEL is taking the whole sector down with it, due to there being in bankruptcy protection. I also believe this is just temporary and we will recover when Earnings come out or possibly sooner depending on press releases.
According to my records for about 6 months now, the vast majority of trades is in blocks of 100 and 200 pcs. Could that be automated trading? I don't think anyone of us (as a person) places that kind of orders.
