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 that have sound business prospects and achieve 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 135,000-plus 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 that they find equally promising.

Of course, this is not a list of stocks to buy -- or, for the monster stocks that our CAPS All-Stars have already found, to sell. Just consider them starting points for your own further research of extreme buying opportunities.

In search of Bigfoot
Apparently, the bank bailouts worked. Hooray, we've been saved!

What else can we think? Although the Dow Jones U.S. Financials index is still down 6% year-to-date, Citigroup and Bank of America (NYSE:BAC) have more than tripled in value this past quarter, while JPMorgan Chase and Wells Fargo (NYSE:WFC) have doubled. We're seeing green shoots all around us, and everything's looking up.

Or is it? Unemployment continues to climb, even if at a slower pace. The figure stood at 9.4% in May and may very well crest above 10% by next year. Job losses will continue to pressure the housing market as homeowners grow increasingly unable to make payments on their mortgages. As delinquencies and foreclosures rise, the collapse of housing prices will continue spurring further losses. And despite assurances to the contrary, the financial system is still a basketcase that holds the great potential for escalating on additional loan losses.

Those vaunted "stress tests" looked only as far ahead as 2010. When the next wave of mortgage resets begins in 2011 and beyond, another tsunami of foreclosures may yet swamp the financial markets. And we haven't even begun to discuss the commercial mortgage situation.

And that's why the Direxion Daily Financial Bear 3X Shares exchange-traded fund could be such a monster performer. It seeks daily investment results corresponding to three times the inverse of the daily performance of the Russell 1000 Financial Services index.

Investing in this ETF now might be a tough row to hoe, with everyone feeling euphoric about the economy. And that's why weberse views this one only as "a short-term play against the financials." Our CAPS member continues: "I intend to buy FAZ today and hold it for a few days, maybe into early next week. I believe the large bank stocks got ahead of themselves in terms of stock prices and all the secondary offerings diluted the shareholders and so the prices will have to reflect that."

It is difficult to recommend this ETF as a core holding of one's portfolio, but the possibility that all of those green shoots will wilt and turn brown does seem substantial. But whether it happens next week or next year is still tough to gauge.

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 at 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.
