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
Its foray into the mortgage business turned E*TRADE Financial's operations into a big, steaming pile, and the stock still hasn't recovered from the shakeout of the housing industry's implosion. Yet the once-and-future focused discount broker has put much of that debacle behind it and is looking at better volumes in its stock trading operations now to carry it forward.

While one analyst thinks the banking business is going to hold it to just limited earnings growth, he's also of the mind that E*TRADE is back on track and returning to its roots as a discount online broker will serve it well, maybe even making it an attractive acquisition target. Highly rated CAPS All-Star member watchmesoar agrees, thinking that value investing legend Benjamin Graham would be smitten by the stock:

I think Ben Graham would like it. Stock is really beaten up to to loan losses on mortgages. Underlying business is healthy. Mucch risk, but it sure is cheap. Upon reading various articles, they seem to have very good customer relations. Wouldn't bet the house, but deserves a position in your portfolio.

Outsized opportunities
That's the thing about allowing expectations to build to unreasonable levels. Fail to clear the raised bar and all of a sudden everyone turns against you. Such is what happened to graphics-chip maker NVIDIA, which soundly beat analyst expectations for sales and profits, but didn't go as high as the whisper numbers were suggesting they should. Even though it handily beat forecasted sales of $957 million, it didn't reach the $1 billion mark many were apparently hoping for.

CAPS member Baseballnorth sees the recent sell-off in NVIDIA's shares as a screaming buy opportunity that's likely to outshine the market for the foreseeable future:

Wow! Wow ! Wow! The company announces today huge profits, it states that it will have a hard time to meet the demand for it's products, yet the share price is down a HUGE 7% because people 'expected' even better results.

Can you spell buying opportunity? This is a prime example of a very strong company, with a very good product and very little competition. It is well managed and the directors have a vested interest in its success. I like all of those points. This makes NVIDIA a company that will consistently beat the market for the foreseeable future.

The CAPS community remains solidly behind the chip maker, despite potential new competition from Advanced Micro Devices (NYSE:AMD) on the horizon. Nearly 96% of CAPS members rating NVIDIA believe it will outperform the broad market averages. Head over to the NVIDIA CAPS page and chip in with your opinion on this 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.
