Cramer Weighs In On BlackBerry, Opendoor Technologies And More

On CNBC's "Mad Money Lightning Round," Jim Cramer said a deal with Amazon Web Services is not enough for him to pull a trigger in BlackBerry Ltd BB.

FuelCell Energy Inc FCEL is not as good as Plug Power Inc PLUG.

Opendoor Technologies Inc OPEN is a good one, thinks Cramer.

American Superconductor Corporation AMSC is a spec and it could work if this continued movement towards speculation stays strong, said Cramer.
