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 150,000 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 technical analysis pinpointed a reversal in Palm's fortunes, as CAPS member TraderMikeSays indicates, or is it yet another example of a "dead cat bounce" that DarthMaul09 says has the smartphone maker rising with the market generally?

Technical analysis is a tricky thing, because even TraderMikeSays says you can get caught flatfooted by a "reversal."

Palm is currently showing a strong reversal coming out of oversold territory. It looks to have bottomed-out for the moment. It could just be a short-term trade, but it could gap-up here with that overhead vacuum in the chart. Relative strength is increasing and the Stochastic, an early indicator, is climbing. If it is unable to breech its moving averages, it could reverse again and head back down for a retest of the lows. If the lows hold on a retest, it will be an excellent buying opportunity. Just watch-out for a reversal so you don't get caught sleeping at the switch.

Yet it's when you look at the business of Palm that you get the idea that perhaps it's a little more than just market mania involved. The company's Pre and Pixi phones aren't a hit with consumers (could it have been those annoying, cutesy Pixi commercials that turned everyone off?) and the wireless carriers have slammed the brakes on future orders. That gives credence to DarthMaul09's contention Palm is simply rising in sympathy with the broader market.

Dead cat bounce with the general rise in the market, but its competitors are just too good for this company to survive. They will go the way of the commodore computer, the question is when. Their only hope is to be bought out by a company with more cash than brains.

At least he holds out hope that Palm will be bought out by a rival. The rest of the CAPS community isn't so generous, as more than half of the 1,450 members who have rated the smartphone maker believe it will underperform the market averages, or worse.

While one of the Fool's tech gurus, Tim Beyers, concurs that a buyout is possible (if not necessary) to save the company, you can dial up additional opinions on the Palm CAPS page and leave your own thoughts there as well.

A chance for scary growth
