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 firms can help you establish a winning portfolio.

Stalking the monster
To find tomorrow's winners, we'll enlist the more than 125,000 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 possible extreme buying opportunities.

In search of Bigfoot
Considering the number of disappointments mounting up in the tech sector -- earnings have been hit hard at Intel, Dell, and Yahoo! in recent days -- it's not so surprising to learn that hard-drive maker Seagate Technology has also been hit. Maybe that's why, in addition to erasing 10% of its workforce, Seagate reformatted the executive suite, replacing both the CEO and the COO.

But CAPS member joe951 still considers Seagate a dependable drive manufacturer whose products excel:

Seagate (not maxtor brand) makes the most relibable non-enterprise hard drives on the market. Maxtor on the other hand seems to compete on price and make a lower end product. So seagate has the top and bottom of the non-enterprise harddrive market. High dividend will be nice, but even if it is cut by half, it will still be 4%, which isn't bad to get while waiting out for the market recovery.

Sounding the depths of Loch Ness
Top-rated CAPS All-Star member floridabuilder2 recognizes that homebuilder MDC Holdings has a presence in some of the most difficult markets. When Beazer Homes reported the other day that closings and new-home orders were both down by more than 50%, it was an indication that there was plenty more pain to come. But floridabuilder2 sees MDC making it through the rough patch in much better shape than many of its rivals:

MDC is in some of the worst bubble markets. However, the builders that are going bankrupt the fastest are in the worst bubble markets. MDC is going to come out of this much stronger and better positioned. Perma green thumb until the next down turn

A chance for scary growth
