No matter what's going on in the market, and no matter a specific company's history, there are always reasons to consider buying shares in a business. After all, some of the best opportunities in stocks are born from historically bloody times.

Motley Fool CAPS hosts a boatload of opinions from more than 125,000 members on nearly 5,400 stocks, giving good reasons to own -- or sell -- a stock.

In the case of aircraft manufacturer Boeing (NYSE:BA), a total of 3,610 members have given a bullish or bearish opinion on the company. Scouring the detailed information packed in pitches and other comments on Boeing, here are three of the top reasons to buy Boeing today:

Diverse revenue sources: Boeing brings in revenue from a wide range of customers. It supplies commercial airliners to carriers like American Airlines (NYSE:AMR) and Continental (NYSE:CAL) and transport planes to shipping companies like FedEx (NYSE:FDX), the U.S. military, and numerous other international customers. Orders for Boeing planes have continued to roll in from a variety of sources, which also creates business for other companies like titanium supplier Titanium Metals (NYSE:TIE) and engine builder General Electric (NYSE:GE).

Big backlog: It hasn't been all peaches and cream, though -- discord with union workers and production delays helped lead Boeing to slash 10,000 jobs. But Boeing’s backlog still grew 8% in 2008 to a record $352 billion and sits at 3,700 planes. Despite some cancelled orders, demand continues to come in for aircraft from other sources to pick up the slack.

Dividend: While dividend cuts coming from companies like Pfizer (NYSE:PFE) are at the fastest pace in 50 years, Boeing recently hiked its dividend by 5% to $0.42 a share in December. With a healthy yield of 3.9%, many investors see Boeing as the kind of cash-rich company that can double its returns over the long haul.

Of course, there's a lot more devil in the details of these buy-side opinions, which is why CAPS is such a great resource to check and balance your own analysis. You can read the bullish and bearish sides to every stock.
