Famed money manager Peter Lynch called them "10-baggers," stocks that climbed to 10 times the value he paid for them. They're a rare breed, but not impossible to find. Especially when you're a friend of Fools.

If you look back over the market's best stocks, you'll find companies that have risen in value over the past decade by 3,000%, 5,000%, and even 24,000%. They're not penny stocks, but viable companies with sound business prospects -- companies that are achieving phenomenal returns every year. You need to pick only one or two monster stocks to build a winning portfolio.

Stalking the monster
So where can we find tomorrow's monster stocks today? At Motley Fool CAPS, we track the opinions of more than 75,000 investors, who are working every day to help collectively identify such winners.

Of course, this is not a list of stocks to buy or sell -- just a jumping-off point for additional research.

Growth on a platter
As the largest pure-play maker of silicon wafers, MEMC Electronics makes some of the largest platters for the semiconductor industry, which helps those companies produce computer chips more efficiently. Perhaps more importantly for MEMC's future, it produces 95% of all the polysilicon it uses to make wafers. And as solar power continues to grow, MEMC is becoming a major producer of wafers for the industry, whose sales might actually outpace those of semiconductors in the near future.

Those kinds of industry demographics have CAPS All-Stars like mars220 believing that MEMC Electronics will have a bright future:

What a posterboy for solar power. MEMC produces its own supply of silicon wafers and sells to both solar and semiconductor industry. WFR trades at a PE approaching 30 its competitors in the solar industry are trading at 190 PE -- if WFR were just at 50% of its competitors it would be a $180 stock. Look for solar power players to take some winnings off table and start the heavy boarding onto WFR in Q4 of 2007. This stock should be trading at 50 PE by year end 2007 -- as far as 2008 goes, the days of $60 oil are behind us. I doubt OPEC is in a hurry to release reserves to leasen the pain at the pump, with the dollar on the fast decline and no end in sight (interest rates will not be increasing in an election year) oil prices should help spur the solar industry along. WFR is on the launching pad.
