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 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 companies can help you establish a winning portfolio.

Stalking the monster
To find tomorrow's winners, we'll enlist the more than 120,000 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 on extreme buying opportunities.

In search of Bigfoot
As if the housing meltdown, credit crisis, and worldwide recession weren't enough, Mexican cement giant Cemex might also say it suffered a bigger-than-expected loss from derivatives when it presents its update, which is expected today. Its stock has been pounded in recent months. That's led to some divergent views on CAPS, where members like cxsonic think the cement mixer's debt alone is a "staggering" argument against it.

They have a stagering 20 BILLION in debt. Some of it due in December 2009. I do not know how these FOOLS keep recomending this company. The stock has lost almost 75% this year alone !!! They just announced 2 months ago that they lost 711 million USD in derivatives !!!

On the other side, TraderBuckwheat thinks there are plenty of macroeconomic factors in favor of a rebound for Cemex, even if he's coming on board a little early.

I am entering this [prematurely] and don't care. This is the biggest play I know of for Cement and [believe] that we can make some big bank on it. I know it is very tough out there in the [building] sector but [Cemex] has took many strategic [initiatives] to weather this storm. I know we are in for the Storm of my life-time Economically but with the new infrastructure program with Obama we will need Cement.

CAPS member Gumfactor feels that Patterson-UTI Energy has run the gantlet, which means that now might be the time to pick up shares cheap.

Awww...from dirt to darling and back to dirt again. And when does one buy? That's right: when it's dirt. And so - let's put a nice big thumbs up on this solid, cash-rich oil rigger that just doesn't really have anywhere to go at this point but up...or, at least not as far down as many other things. ;)

A chance for scary growth
