Even with everything going on Boeing’s stock price is higher than it was ten years ago. Five years ago it was 4x, I’m sure it’ll recover a good amount from today’s number.
My cynical take is that a lot of investors don’t see what Boeing is doing as mismanagement. They’re in a hugely enviable market position: only one competitor that can’t scale quickly, customers are captive. Boeing management moved to reduce costs (i.e. get rid of expensive unionized workers) while still churning out a large number of planes: success. Some people have died as a result of that, sure, but did you see those profit and loss numbers? Wow-eee.
A year from now Boeing’s stock price will have rallied and they’ll continue on. Maybe an exec or two will take a golden parachute for PR purposes but it won’t mean anything.
