No matter what's going on in the market or 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 computer and printer behemoth Hewlett-Packard (NYSE:HPQ), a total of 2,767 members have given a bullish or bearish opinion on the company. Scouring the detailed information packed in pitches and other comments on the company, here are three of the top reasons to buy Hewlett-Packard today.

1. Not a one-hit wonder
Over the last few years, HP has moved beyond personal computers and printers to keep the growth alive. It has boosted its ProCurve networking business, which has been gaining share and competing with the likes of IBM (NYSE:IBM), Dell (NASDAQ:DELL), and Cisco (NYSE:CSCO). The HP unit recently partnered with Microsoft (NASDAQ:MSFT), Avaya, McAfee, and several other leading technology companies to optimize the performance of its products.                                  

2. Adapting to the economy
Many investors see HP as a solid defensive play, and so far this is bearing out, with the stock holding up better than others as the world economy falls into recession. The company is also adapting the way it sells products in order to put them within reach of all levels of consumers and businesses. For instance, to help entice spending from the small business sector, it’s offering 0% financing for small businesses, and is offering more business-friendly netbooks with Windows XP Pro and Vista Business available as operating systems.

3. Best in class
HP has dominant positions in many of its business segments, something that sure helps in boosting margins and profits. The company also enjoys a strong, worldwide brand, like Apple (NASDAQ:AAPL) or Oracle (NASDAQ:ORCL), giving many CAPS members reason to believe it will continue its strong performance.

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. To see what the very best CAPS members are saying now about Hewlett-Packard, just click on over to Motley Fool CAPS and have a look.
