Finding the next big stock is both satisfying and profitable. Like Nirvana for those early on the grunge scene, or, in my case, Modest Mouse, it's even more rewarding if you can discover greatness before everyone else.

With that in mind, I used our new Motley Fool CAPS screening tool to find stocks whose ratings have risen to four stars (out of five) from one, two, or three stars one month ago. These are stocks with growing bullish sentiment.

They also have:

  • Market capitalizations above $100 million.
  • At least 200 active CAPS picks.

Remember, in the first year for which we have data, newly minted four-star stocks outperformed all other categories, with an average gain of 41%.
