The Next Million-Dollar Penny Stock

Penny stocks can make you rich. Need proof? Every one of these multibaggers was once a penny stock:

The promise of outrageous returns has periodically made even the world's best stock pickers penny stock investors. Peter Lynch has enjoyed the stock market's super-cheap seats in the past, and still does on occasion. The Royce Low-Priced Stock fund has beaten the market for a decade by betting on stocks trading near or below $10 a share, including ValueClick (NASDAQ:VCLK).

Even the All-Stars in our 140,000-plus Motley Fool CAPS community take to penny stocks. More than a few have been richly rewarded.

Pennies from heaven
So why not invest in penny stocks? Well, the warning the SEC issued about them provides one excellent reason to steer clear. But what if we take the agency's definition literally, and limit our choices to stocks trading between $1.50 and $5 a share? And what if we further seek only four- and five-star stocks with a market cap between $250 million and $2 billion? Surely our CAPS screener would return some winners, right?

This week when I ran that screen, 53 stocks made the cut -- including our last topper, Smith & Wesson Holding.

My favorite penny stock this week is Sonus Networks (NASDAQ:SONS), a provider of infrastructure equipment for Voice over Internet Protocol (VoIP) systems. The details:

Data current as of Oct. 29.

I'm not much of a fan of the telecom business, or the telecom equipment business, but Sonus is different. You might call it a bridge to the future for legacy carriers such as AT&T (NYSE:T) and Verizon (NYSE:VZ). Why? LTE.

For those unfamiliar, LTE, an abbreviation for "Long Term Evolution," is an in-development broadband technology that's backed by the legacy carriers and capable of carrying voice, data, and video. LTE is also a direct competitor to WiMAX. Sonus makes IP telephony equipment that is LTE-ready.

There's risk in betting on a technology that has yet to be widely adopted, but the beatdown Sonus has suffered may be overdone. Cash accounts for more than two-thirds of the company's market value at current prices. That doesn't seem fair; it's too early to give up on the idea that telcos will need Sonus' equipment to make the LTE transition.
