What do you think is a good value for Boeing (BA:US) stock? I'm thinking to buy it when it is undervalued?

Just a little meme I found online:)

But in all seriousness, I think a good simple reference point would be to look at Boeing before they announced their Airmax 737 model. I would assume instituitional and retail analysts then would have forecasted their future Cashflows based off that and priced in their stock. However that would not factor in the recent scare and fall in public confidence towards Boeing planes in general. This would be hard to calculate, but the good news is if you are looking to capitalize at an opportunity like this, the fall in public confidence is probably temporary in your opinion against the LR potential of the company. If so, unless you feel markets are underreacting to the current track of flight bans- or that the worst is not over, there already exists a good opportunity to buy into Boeing right now.

Just something to consider, Airbus shares went up quite a bit since Monday. If the market does not correct on Airbus, and still undervalues Boeing, a strategy you can consider is to buy Boeing and short Airbus.

There's potential for higher returns here but risk exposure also higher.
