NEW YORK (TheStreet) -- The alternative fuel sector was setting up for another day of robust gains on Tuesday, but the tides turned for three of the heavy-volume stock plays around mid-session.
Fuel-cell maker Plug Power (PLUG - Get Report) began to dive just after midday, after following Ballard Power Systems (BLDP - Get Report), ZBB Energy (ZBB) and FuelCell Energy (FCEL - Get Report) higher for much of the session. Shortly after, FuelCell and Ballard Power Systems tumbled.
The industry was celebrating a days-long rally in the sector, extended by an above-consensus first-quarter report from FuelCell after the bell Monday.
