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 percent 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.

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 this a starting point for your own further research.

Power up your portfolio
Two major contracts have propelled polymer lithium-ion battery maker Advanced Battery Technologies forward this year; its stock soared back in March, though it has since settled back down. It's gotten a recharge lately, though, as demand for the company’s batteries has created a backlog of orders for almost the next two years, helping the company report record revenue and profit in the first quarter.

As a New York-based Chinese company, Advanced Battery Technologies is attracting investor attention. But CAPS players like ennui understand that a healthy dollop of caution is still necessary when plunking real dollars down on it:

They will be powering electric buses, cars, and every kind of gizmo you can imagine. This ... is the kind of speculative play that is worth a shot, in my book. A small shot--one that can't lose you much money if it bombs out, but which can pay off nicely if the technology catches on.

Planting the seeds
Another foreign company that is high on investors’ buy lists, but isn’t quite so speculative, is fertilizer maker Sociedad Quimica, which has been a beneficiary of the surge in commodity prices. Its potassium nitrate fertilizer is cheaper than potash, and the company is said to provide about half of the world's supply. Moreover, it is also the world's largest producer of lithium, which -- as Advanced Battery knows -- could be a big part of the solution to the world's energy problems if lithium-ion batteries go big.

CAPS investor donktastic feels Chemical & Mining Co. of Chile, as it's more commonly known, will profit from the tag-team duo of fertilizers and batteries to succeed:

Looks like a well diversified company that produces products which are in high demand like potassium nitrate (fertilizers), lithium for batteries, and other various chemicals. I think there's only upside. We'll see they can become part of the solution for the automotive industry getting off of gasoline/diesel by taking advantage of the rechargeable and fuel cell market.
