RE:Just my opinion.The Cseries program is baby bird that has not reach yet the crusing speed of production and selling... BBD didnt deliver yet the first plane!!!! IMHO, don t push on the sell trriger to get bit of profit and regret it ... or be afraid of normal fluctautions of the market +/- ... BBD will worth 25$ and more in few years when the Cseries break the duopoly of A&B. Watch out!!!
