Are you really a growth investor?

It's worth asking. Even though talk of a growth-stock rally has spread to the pages of The Wall Street Journal, investing in fast movers can be a stomach churning-experience.

Yesterday offers a good example. When Wal-Mart (NYSE:WMT) lowered its forecast for full-year earnings and Mattel (NYSE:MAT) announced yet another recall, investors fled for the exits. And the high-growth tech stocks? They sold off like all the rest.

Witness Apple. On the day that the collected solo works of John Lennon went on sale at the iTunes store, the stock was down by nearly 3%. Surprised? Don't be. Market panics occur daily. That's why all-star investors bet on growth over the very long term. They know that:

  1. Businesses that make investors billions always begin as growth stocks.
  2. The best of them feature massive and identifiable competitive advantages.
  3. Growth as a strategy has the capacity to deliver 20% or greater annual returns for decades at a time.

How we do it
Of course, not all growth stocks will do. Our weekly hunt seeks the next great multibagger. But unlike David Gardner and his team at Motley Fool Rule Breakers, who scour everything from financial statements to trade magazines to clinical reports in their research, we're going to rely on our Motley Fool CAPS investor-intelligence database.

Specifically, we're looking for stocks that have earned a five-star rating in CAPS, and which are expected to grow their earnings by at least 20% annually over the next five years. Five-star stocks are those that the community, on the whole, believes will outperform the S&P 500.

Let's have the list
Now, with that preamble behind us, here are five more top growth stocks:

Bear in mind that this isn't a list of recommendations. Instead, I offer these stocks as candidates for further research. But, of these five, I'm most intrigued by Global Gains pick GigaMedia, an online entertainment specialist based in Taiwan.

Why? A 0.40 PEG ratio helps. So does the endorsement of Bill Mann, who, in picking the stock for the January issue, theorized that the ever-increasing number of Asians going online would substantially boost revenue and, thereby, cash flow. He's been right thus far.

But CAPS investor QualityPicks seems to think there's plenty of room to run from here:

Excellent return on equity of 28% and on capital of 26%. This company is growing at 30% or more. At this price, [it] is starting to look very cheap. This stock should be worth $20 dollars.
