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.

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 what could be extreme buying opportunities.

In search of Bigfoot
Despite assurances from the Fed chairman to the contrary, nationalization of the banking system remains a top concern for investors. Even with the government stopping short of full seizure of Citibank (NYSE:C), it hasn't fooled many about who's really in charge. When you can dictate that a company has to take your bailout money and must replace members of its board of directors, you may as well be running the whole show. While Citi shareholders haven't been completely wiped out yet, as they undoubtedly would be if the financial services giant was nationalized in name as well as fact, how long before it ends up like AIG, on permanent life support from the taxpayer?

It's the specter of lingering on in a nether world, like Citi, that has other banks seeing their shares fall as they prepare for a "stress test" of viability. Investors are right to ask just how much will it cost to save everyone? Bank of America (NYSE:BAC) was once considered a bulwark of the banking system, but may need a third infusion of cash, and Wells Fargo is now feeling pressure build over whether it needs to cut its dividend like everyone else. While its Tier 1 ratio fell in the fourth quarter, the bank maintains it has a strong balance sheet and the highest credit ratings given to banks by Moody's Investor Services.

As light on details as Treasury's stress test plan is, a number of investors like CAPS member Hopper39 remain convinced that Wells Fargo is still among the best of the banks and will pass even this trial.

Anyone think that Geithner's stress test plan is anything but arbitrary? It would be a failure of EPIC proportions to further erode confidence by designing a test which further erodes public confidence in the stability of those banks left standing. I'm not saying give everyone a pass, but it's not exactly helpful to set the bar so high that all banks become de facto zombies by the new arbitrary Treasury standard. I think details of the plan, due out shortly, will be good for the strongest banks left standing, [JP Morgan Chase] and [Wells Fargo].

A chance for scary growth
