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 companies can help you establish a winning portfolio.

Stalking the monster
To find tomorrow's winners, we've enlisted the help of more than 160,000 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.

In search of Bigfoot
Has the death of one-time rival Movie Gallery given Blockbuster (NYSE: BBI) a reprieve? Almost three years after it first filed for bankruptcy protection, Movie Gallery came to its inevitable end and plans in the coming weeks to close down all of its stores, including those it ran under its Hollywood Video brand.

Because of its similar bricks-and-mortar model, Blockbuster would seem to be the primary beneficiary of Movie Gallery's demise. But Coinstar's (Nasdaq: CSTR) Redbox will win, too, as the proliferation of its kiosks will give Movie Gallery's former customers a convenient place to turn. However, because of restrictions imposed by the studios on renting new releases, Coinstar's upside looks limited. Blockbuster, without the same restrictions, probably benefits more.

But the real winner is probably going to be Netflix, whose rent-by-mail service and streaming video offerings were what really brought Movie Gallery to this end. It was unable to compete against the leaner business, and Blockbuster investors would be well-advised to take note.

CAPS member k00l says Netflix is getting the necessary deals done to ensure its longevity:

With a little forward thinking, Netflix will be positioned to actually offer movie distribution directly to home theater movie distribution servers; such as DVRs. This could lower the cost per movie while increasing the profits of the movie makers. This could eliminate several middlemen; manufacturing, distributors, retailers.

A nice tailwind
Despite the proposed merger of Continental Airlines and United Airlines (Nasdaq: UAUA), the plans of both Boeing (NYSE: BA) and Airbus to boost production should be a signal that aerospace is poised for an attractive return. That bodes well for Titanium Metals, the world's leading producer of the metal that's in high demand by aerospace applications. More than two-thirds of its milled products shipped to the commercial aerospace sector in 2009.

Back in January, CAPS member BioBat underscored reasons investors should be excited about Titanium Metals:

-Boeing and TIE have extended their titanium purchase agreement 
-Boeing just successfully tested the 787
-The 787 requires a heck of a lot more titanium than your standard airplane (15% vs as 2%-9%) keeping weight down and increasing fuel efficiency
-titanium is present in many car parts and car sales are in their regular cyclical downturn and will grow significantly over the next 5 years

A deep breath
Even a major oil spill and improving economic data apparently can't drive natural gas prices higher, and that's problematic for U.S. Natural Gas investors. Look at the ETF's chart over the past year, and you'll see why the industry's drill-to-hold policy has been a disaster for pricing. We're still awash in inventory that sits well above five-year averages.

CAPS All-Star PearlandTX doesn't see the coming months changing the status quo: "Summer season is likely to result in lower demand for natural gas and higher natural gas inventory."

A chance for scary growth
