Stocks that climb to 10 times their original price are a rare breed, 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 have achieved 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 monster stocks, we'll enlist the 115,000 members at Motley Fool CAPS. We've compiled a list of the most successful CAPS players, 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, to sell. Just consider them starting points for your own further research of extreme buying opportunities.

Hot fun in the summertime
At just 15 times trailing earnings and 10 times earnings over the next 12 months, ReneSola is competitively priced against rivals such as LDK Solar (NYSE:LDK), which sits at 22 times trailing earnings and 17 times forward earnings. Manufacturing silicon into wafers for use in solar panels, ReneSola has gotten beyond its awkward stage and has found customers desirous of its multicrystalline technology, but the recent stock offering is diluting shares -- something that Fool colleague Toby Shute cautioned investors about previously.

Margins, profit growth, and debt structure all lag LDK, but the industry is still showing healthy growth signals, and analysts estimate long-term growth to be in the 28% range. That's enough for CAPS member owshx, who believes that solar energy has grown up during the past decade. Our player also says that although oil's inexorable climb has finally eased a bit, the resulting pullback in solar stocks will be only temporary.

Solar has come along way in the last 10 years, [and] efficiencies are up thanks to new state of the art manufacturing technologies. When making of all these solar modules, it almost always starts with Solar WAFERs and ReneSola supplies them to all the big names: JA Solar (JASO), Solarfun [Power] (SOLF), and Suntech Power (STP).

Take a look at the amazing growth going on in these three, and you'll see why ReneSola revenues are up from $84M in '06 -> $250M in '07 -> $125M this past QUARTER.

You've got that certain glow
Although the price of uranium has been in a meltdown recently, falling from its highs of $136 a pound to below $65, the desire to find alternative forms of energy to free us from foreign sources of fossil fuels ensures that nuclear energy remains a viable option. And that ought to keep uranium prices from going too low. Cameco, as the world's largest uranium producer, stands to benefit if we see a new push for building new nuclear power plants, as do producers of low-enriched uranium such as USEC (NYSE:USU).

Other forms of alternative energy give people the warm fuzzies, but nuclear power doesn't need the same ramp-up that wind or solar does and is reported to be much cheaper than either. That reality has CAPS member KipLargo thinking the next few years are key for our country's health.

[T]he US, to maintain and grow economically will eventually have to go nuclear. Green tech won't make up the difference in the amount of time we need them to, and the countries that have the resources we need don't like us. Uranium levels the playing field resource-wise. If we were smart, the next administration would start building nuclear plants in the next 4-5 years.
