I am always looking for a good deal, whether that means buying an extra box of Golden Grahams when they're on sale or pouncing on undervalued stocks. The idea that anybody would sell a stock for less than it's worth may seem silly, but legendary value investor Ben Graham (no relation to the cereal) tells us, by way of allegory, how we can look out for these situations.

In The Intelligent Investor, Graham introduces readers to a wacky chap named Mr. Market. Mr. Market's game is to pay you house calls on a daily basis to offer to sell you interests in businesses he owns or to buy from you interests in businesses you own. Sometimes Mr. Market will show up at your door very excited and offer you premium prices for your holdings, while at other times he'll be inconsolably depressed about the future and will offer to sell you what he has for as low as pennies on the dollar.

To find some of the stocks that Mr. Market is depressed about, I've turned once again to The Motley Fool's CAPS investor community. Each of the companies below had been given a five-star rating (the highest) by our community of investors just 30 days ago:

Data from Motley Fool CAPS as of Dec. 8.

As the table shows, these stocks are all still very well-regarded by the CAPS community despite their underperformance over the past month. While these are not formal recommendations, they could be a great place to kick off further research. I'll even get you started with some thoughts on Motley Fool Global Gains pick ABB.

Why so blue?
Although ABB's earnings announcement hit the newswires more than a month ago, it's not done dragging the stock down. In late October, the company reported both revenue and profit (less extraordinary items) down noticeably from the prior year. And that profit decline came despite a hefty $1 billion of cost-cutting over the first nine months of the year.

Those declines may not have been all that surprising, but what may still be weighing heavily on investors' minds is that new orders fell significantly and ABB's management team basically threw up their hands and said that they were unsure "how quickly capital investments by customers will recover from the downturn."

Since the earnings announcement, the company has also been implicated in a corruption scandal via its unit in Texas, and has seen its stock downgraded by HSBC. While neither of those are huge events, getting kicked while you're down is never a pleasant experience.

What the bulls say
But if there's anything a Fool like me knows, it's that it's the big picture, not the most recent quarter, that is the primary concern when evaluating an investment. And ABB shines the brightest when we look at the bigger picture.

The company's largest business is supplying heavy-duty equipment for electricity grids around the world. Emerging economies are helping electricity usage grow by leaps and bounds, while more mature economies are sitting on aging equipment that will need to be replaced or upgraded. This puts a lot of potential business on the table for ABB, particularly as we emerge from the global recession.

More than 1,600 CAPS members have rated ABB's stock an outperformer. All-Star yooperking gave ABB a thumbs-up back in mid-2008 and said:

ABB is in the driver's seat of the vehicle headed into the future of their utitlity and industry customers, with a range of products, systems and services for power transmission, distribution and power plant automation. The Co. delivers automation systems for measurement, control, motion, protection and plant optimization, enhancing their customers productivity and efficiency.

But here's the important question: Do you think the recent drop has created a good buying opportunity? Or will ABB continue to struggle?
