Based on the aggregated intelligence of 115,000-plus investors participating in Motley Fool CAPS, the Fool's free investing community, aerospace giant Boeing (NYSE:BA) has earned a respected four-star ranking. While five-star stocks have been the best performers, our data has shown that four-star stocks still outshine the market by a significant margin and shouldn't be taken lightly; conversely, low-rated stocks have woefully lagged the market average.

With that in mind, let's take a closer look at Boeing's business and see what CAPS investors are saying about the stock right now.

Over on CAPS, fully 515 of the 591 All-Star members who have rated Boeing -- some 87% -- believe the stock will outperform the S&P 500 going forward. These bulls include addaam78 and marc64, both of whom are ranked in the top 10% of our community.

In late May, addaam78 noted that the "carbon based 787 has a competitive advantage of 6 years against Airbus and makes Boeing the new leader of new carbon based jets for the future. With a backlog orders of 6 years and a good valuation I think it's a good bet."

A pitch from marc64 one month earlier shares that bullish attitude, writing:

BA's PEG is great, backlog of orders is great, earnings growth is spectacular.

While airlines are increasingly in the news as unviable (and this hurts airplane builders), the real problems remain fuel and fierce competition. Boeing's great business advantage is a new generation of jets that are 20% more fuel efficient (and I like that they can keep the air pressure inside the jet at a more comfortable level, making long trips much more bearable). At the same time, time is running out on whole fleets of jets that need to be replaced.

As the weakest airlines shake out, competition is reduced, and as oil prices go down (as the strengthening dollar makes oil seem cheaper), and as the oil producers lower their margins to nip cost-effective alternatives in the bud), BA will look like an increasingly great idea, and investors will pile on.
