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 Gammon Gold (NYSE:GRS).

Even the All-Stars in our 150,000-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, 50 stocks made the cut -- including our last topper, ReneSola.

My favorite penny stock this week is RF Micro Devices (NASDAQ:RFMD), a components maker for mobile devices. The details:

I like this stock for a couple of reasons. First, I like the trend in the numbers. RF Micro Devices has enjoyed a steady rise in gross margins and returns on capital in the last few quarters.

Second, I like that the company's customer list includes Nokia (NYSE:NOK) and Motorola (NYSE:MOT), and I can appreciate why they're buying from RF Micro Devices. RF Micro's chips are, effectively, tiny radios that allow wireless devices to connect with wireless infrastructure such as cell towers, Wi-Fi networks, etc.

Last month, RF Micro beat analyst expectations for third-quarter profits as revenue soared 24%. And yet the stock still trades for less than 9 times the next 12 months' estimate for earnings. I can't imagine investors allowing this stock to continue trading at such a discount for long.

But that's my take. Now it's your turn to weigh in. Would you buy RF Micro Devices at today's prices? Let us know by signing up for CAPS today. It's 100% free to participate. You can also weigh in via the comments box below.
