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, headed by Fool co-founder Tom Gardner,  is currently beating the market by 18 points with its recommendations of small-cap companies that hadn't yet registered on Wall Street's radar -- like Nuance Communications (NASDAQ:NUAN), up 144%

With these examples 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 earnings 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, in the first year for which we have data, newly-minted four-star stocks like Intuitive Surgical (NASDAQ:ISRG) (up 238% during that year) outperformed all other categories, yielding 41% on average.

Here are some of the companies I found:
