Stocks climbing to 10 times their original price are rare breeds -- 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 by taking advantage of the market's weaknesses. These aren't penny stocks; they're viable companies with sound business prospects that are achieving phenomenal returns. Finding just one or two of these monstrously successful firms can help you establish a winning portfolio.

Stalking the monster
To find tomorrow's winners, we've enlisted the help of more than 150,000 monster trackers at Motley Fool CAPS. We've compiled a list of the most successful CAPS members, dubbed All-Stars, whose picks have doubled, tripled, or even quadrupled 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 of extreme buying opportunities.

In search of Bigfoot
It didn't receive the universal accolades that Apple unveilings typically draw, but the iPad still garnered adherents who believe it will be a game-changing development for tablet PCs. CAPS member joshbk views it as a key transition in portable computing:

If you've ever made a website, you probably understand that the Internet is meant to be interactive. A good site jumps out at you and invites you in. This is why the iPad succeeds on all levels - not only as a fancy media-based extension of the iPod and iTouch, but as a portable tool to interact with the Internet. Simply moving beyond the mouse and keyboard is a huge step toward, first, making sites more interactive, and second, making the content more engaging. You're almost literally touching the Internet.

Not everyone agrees, however. All-Star chundarr, for instance, sees the iPad's failings as building up a layer of intolerance among consumers:

Expensive toys that [don't] play well with others. (No flash on the Ipad? Really?) Sooner or later people get sick of that.

With a potentially groundbreaking GPad offering from Google (Nasdaq: GOOG), and Amazon.com (Nasdaq: AMZN) possibly upgrading its Kindle to become an iPad clone, there will be plenty of challenges that will necessitate Apple's putting forth a truly revolutionary product that will once again win plaudits from the critics.

The CAPS community has always been partial to Apple. More than 91% of the 23,000 members who have rated the i-maker believe it will outperform the broad market averages. Head over to the Apple CAPS page and pad it with your opinion on the company's future.

A chance for scary growth
It takes more than a few All-Star picks and a quick paragraph to make buy or sell decisions, so start your own research on these stocks on Motley Fool CAPS. You can read a company's financial reports, scrutinize key data and charts, and examine the comments your fellow investors have made -- all from a stock's CAPS page. And while you're there, weigh in with your own thoughts on whether you think these are tomorrow's monster stocks.
