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 firms can help you establish a winning portfolio.

Stalking the monster
To find tomorrow's winners, we've enlisted the help of more than 170,000 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 extreme buying opportunities.

In search of bigfoot
With M&A activity in the pharmaceutical industry still a hot topic as acquisitions become a quick route to bolstering pipelines, Delcath Systems got caught up in the fervor of guessing who might be bought out next. Bristol-Myers Squibb (NYSE: BMY) was supposedly willing to pay upward of $15 a share to get hold of Delcath's drug delivery system -- a huge premium to Delcath's price at the time.

But in a presentation at a cancer meeting this past summer, Delcath failed to convince analysts that there was really a benefit for patients using its percutaneous hepatic perfusion technology. Although the clinical trials were not specifically designed for survival issue, it was a key component of the outcome as reported.

CAPS member dtannen, however, is not particularly concerned about PHP as he thinks Delcath has even bigger opportunities before it: "Delcath should get approval for melanoma mid-2011. The opportunity is much bigger for its PHP system though."

Why not head over to the Delcath Systems CAPS page and tell us why it will still be able to deliver on its promises.

A good reception
We've heard how Swift Energy has charged the Obama administration with imposing a de facto moratorium on drilling in the Gulf through burdensome regulation. After all, since the moratorium was lifted last month, exactly zero permits have been issued.

Overcoming the daunting regulatory morass was enough to convince Plains Exploration & Production to make plans to exit the Gulf in August while expanding its onshore operations. While it may have overpaid for its Eagle Ford oil patch, that shale formation is proving to be the next hot region for discovery with even China's CNOOC wanting in by buying a third of Chesapeake Energy's (NYSE: CHK) stake.

With 97% of the CAPS members rating Plains to outperform the market, they apparently see the benefits of Eagle Ford far outweighing any overpriced tag it may have paid.

But only you can decide whether the oil exploration company is right for your portfolio. Add it to your watchlist and have all the Foolish news and analysis about the stock aggregated in one place.

Inflating values
Well, are we in a tech rout or not? When the industry researchers at iSuppli suggested this summer that a major supplier of chip-making equipment may have difficulty meeting demand, shares of Intel (Nasdaq: INTC) and Texas Instruments fell. Forecasts of slower PC growth didn't help either, and Cisco's (Nasdaq: CSCO) earnings caused tremors, too.

Yet despite all the fretting, PC sales grew 7% sequentially and more than 10% year over year in the third quarter. TI's stock, in fact, is up 34% since its low point at the end of August and has some thinking it may be the perfect stock to buy to come out of the tech storm.

investorval thinks Texas Instruments has changed for the better over the years, but emrddr says it hasn't proven itself just yet: "low debt to equity is good but there is trend toward lower earnings as well as operating cash flow."

Join with him on the Texas Instruments CAPS page and let us know whether it will continue to chip away at conventional wisdom.
