Do you know why I own Boeing stock? Here's why. With all the interminable delays on 787 production, they still have a backlog of something like 800 orders for the plane. There have been very few cancellations. Why aren't the customers canceling their orders to sign up with the competition? Because there is no competition for this product, even with a 3 year delay.
When Boeing straightens out the production woes (and they will) and the planes start rolling off the assembly line, BA goes straight to $100/share.
