Warren Buffett made billions buying undervalued companies before market sentiment swung back in their favor. Legendary sandalwood bandit (and handlebar-mustache-wearer extraordinaire) Veerappan made his personal fortune by staying one step ahead of the law. And our Motley Fool Hidden Gems newsletter service is currently beating the market by 20 points with its recommendations of small-cap companies that hadn't yet registered on Wall Street's radar -- like Buffalo Wild Wings (NASDAQ:BWLD), up an average of 171% over its several picks.

With that example in mind, I used our new CAPS screening tool to find the stocks poised for big gains -- before Wall Street catches on.

These companies have:

  • Trailing three-year EPS growth of at least 10%.
  • Market capitalizations of at least $200 million and no more than $10 billion.
  • Four- or five-star ratings in CAPS, up from one, two, or three stars at the beginning of 2008.

Remember, since the launch of CAPS in 2006, five-star stocks such as Petrobras (NYSE:PBR), up 21% in the past year, outperformed all other categories, to yield 12% on average.

Here are some of the companies I found:
