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 hundreds 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 monster stocks, we'll enlist the more than 95,000 investors 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 some of their recent picks for stocks they find equally promising.

Circling the wagons
After starting as a mineral exploration and mining company, TransGlobe switched gears in the early 1990s to become a successful oil and gas exploration concern with interests in Canada, Yemen, and Egypt. While some might think this could spell trouble if regional unrest develops, remember that the company has been expanding its base aggressively through acquisitions which analysts feel will be accretive to earnings this year while boosting production growth.

It's that kind of movement for which CAPS investors like spiderone27 have been waiting. Indicating the long-term position he's had on the stock, spiderone27 felt last September that it looked very cheap and would reward investors willing to hold for the long term:

TransGlobal Energy Corp. has always seemed to have all the right signs of a great company to invest in. While some of us have been sitting here for the last five years waiting for something to happen, it has seemed to be preparing to start the upward climb. While they have been aggressively expanding [their] operations over in the mideast in Yemen they have seemed to remain profitable. I would say that this stock is way undervalue and if you hurry you have a chance to stake your claim while it is this cheap. Although I think that this stock will do big things in the next year or so, overall I feel it is going to keep moving ahead with time!!!

CAPS player doctorstroh also feels the company has excellent long-term growth prospects, even if he likely won't be staying in for the long haul:

Smaller yet quickly growing oil company without quickly growing debt. As of now there is no dividend which I generally require in my long term investments. I think this stock will rise at a steady pace for the next few [months] and even for the next few years but I plan on cashing this one in for a profit in a couple months.

More than 97% of the more than 360 CAPS investors weighing in on TransGlobe rate the company to outperform the market.
