The fundamental long term problem with BBD is that the transport segment is static - not much growth, they can not sell very many of thier existing regional jets and the ones that they can sell there is little to no profit and lastly the CSeries is about 36 months late to market (and getting later) with Airbus, Boeing and Embraer scooping up the big orders.

 

Fun for trading, terrible for investing.
