Ah, the joys of skepticism.

We rebel investors at Motley Fool Rule Breakers believe that multibaggers in the making, while not often cheap by the numbers, are always misunderstood. The extraordinary skepticism they face makes them excellent value stocks.

Hitting just one of these home runs can make all the difference to your portfolio. Just ask David Gardner, who bought Amazon.com at a split-adjusted price of $3.24 a share in 1997. He's up more than 2,100% since.

Stocks like Amazon helped David produce nine years of better-than-20% average annual returns in the real-money Rule Breaker portfolio, even while suffering stinging losses from Guitar Center and 3Dfx, among others.

Let the haters be your friends
David continues this home-run investing tradition today at Rule Breakers. You can follow the moves of his rebel alliance with a free trial to the service. Or, if you prefer to pick your own stocks, there's Motley Fool CAPS, a 100% free stock-picking community whose 93,000 participating investors rate stocks on a scale of one to five stars. More than 5,500 rated stocks are in the database right now.

How can this help you? Each week, using CAPS, we'll search for one- and two-star stocks that have at least 5% of their available shares sold short, but which are expected to grow their earnings by no less than 15% over each of the next five years.

Bear in mind that this isn't a list of recommendations. Instead, I offer these stocks as candidates for further research.

There isn't a lot to work with, is there? National CineMedia has the growth numbers, but investors have so little faith in the business that, in January, I named it one of the world's worst stocks. MasTec made that list in November and February.

Cleared for your portfolio
Of all the stocks on today's list, Clearwire, which proposes to do for WiMAX what AT&T did for the analog telephone, is my favorite.

Not just because of the company and its pioneering leader, Craig McCaw. I'm bullish on the industry. And I'm not the only one. Here's a pitch made by CAPS investor Porter77s at the end of last month:

Why use Wi-Fi when you can have WiMAX? Look at the spectrum auction. Clearwire has tons of spectrum, so wouldn't the stock be worth the same as what was just paid per spectrum band? It isn't being valued that way.

Close. Comcast (Nasdaq: CMCSA) and Time Warner Cable yesterday proposed a multibillion-dollar investment to create a national WiMAX network. In that plan, Clearwire and Sprint Nextel (NYSE: S) would provide the needed infrastructure. Can you imagine the billions more in value such a deal will create for Clearwire once the network finally goes live?

I can, but I'm more interested in what you think. Would you buy Clearwire at today's prices? Let us know by signing up for CAPS today. It's 100% free to participate.
