Boeing (BA) is the wind beneath investors' wings.
The aircraft manufacturer was the best performer in the Dow Jones industrial average last year, with a gain of more than 80%.
But the stock hit some turbulence recently. Boeing shares are down about 6% so far in 2014, driven largely by a disappointing outlook for earnings this year.
Watch: Boeing stock gets grounded
Despite the recent pullback, Boeing (BA) appears to have worked out all the kinks with its 787 Dreamliner. It also recently settled a labor dispute on favorable terms and has a large backlog of orders.
Analysts are predicting earnings growth of about 10% a year on average for the next few years, but Boeing is particularly vulnerable to any downturn in the economy. That may be why investors have been bailing out recently.
