Stocks that climb to 10 times their original price are a rare breed -- but they're not impossible to find. Especially when you have Fools for friends.

The market's best stocks include companies that have risen dozens of times in value over the past decade. These aren't penny stocks; they're viable companies with sound business prospects, achieving phenomenal returns every year. Finding just one or two of these monstrously successful firms can help you establish a winning portfolio.

Stalking the monster
To find tomorrow's monster stocks, we'll enlist the more than 96,000 investors at Motley Fool CAPS. We've compiled a list of the most successful CAPS players, dubbed All-Stars, whose picks have doubled, tripled, or more in price. Then we've plucked out some of their recent picks for stocks they find equally promising.

Of course, this is not a list of stocks to buy -- or, for those monster stocks that our CAPS All-Stars have already found, sell. Just consider them starting points for your own further research.

Not playing around
One area of consumer electronics isn't experiencing much of a slowdown: video games. Statistics from the market researchers at NPD Group show that monthly video game industry sales were up 34% in February, to $1.3 billion. While hardware sales grew a healthy 19% -- with Nintendo's Wii continuing to beat consoles from both Sony (NYSE: SNE) and Microsoft -- the software segment was growing at a rip-snorting 47% clip.

It's tough to tell which maker of individual titles will have the next breakthrough game. Divining whether the PlayStation will once again trounce the Xbox is a (small-f) fool's errand, particularly when the sales data can get lost in a consumer-electronics conglomerate like Sony. Investors may be better off choosing a company that sells all the titles, carries all the consoles, and wins no matter who else does. That's the theory behind Motley Fool Stock Advisor pick GameStop, a picks-and-shovels company for the video game industry.

This retail sales engine has dominated its niche, and CAPS investor TurtlePerson2 likes the fact that the demographics of game players are changing:

Video games are a huge industry and are going to keep growing... We're entering the point where parents have grown up playing games meaning that it's now the rich adults ... buying games. Gamestop makes a great margin on used game sales and a decent margin on new games too... The reason this stock is so successful is because it has bought out most of the competition... In the long term, I think that poor customer service and the rise of digital distribution will hurt Gamestop to the point where it will either have to reinvent itself or close, but I'm very bullish on the next year or so.

CAPS All-Star Powerman4160 agrees, seeing video gaming as a far more mainstream activity than in the past. With blockbuster titles like Grand Theft Auto IV arriving, he thinks GameStop ought to make out like, well, a bandit:

Success for GameStop is highly attributable to video game play attracting a mainstream audience, with the demographic expansion having much to do with new consoles like the Wii, which pull back on the geekish complexity of typical content aimed at hardcore gamers. The release of Grand Theft Auto IV could net the company more than $100 million--in a single week.

With more than 96% of the 2,400-plus investors rating GameStop an "outperform," it seems most have come to the same conclusion.
