Suddenly, it seems as if the investing world has gone loony.

Analysts say that the tech stocks that broke the hearts of investors in 2001 are on pace to grow faster than all other sectors during 2007. But if research is to be believed, average P/E ratios don't reflect the expected outperformance.

Perhaps that's why a growth stock rally is under way. Or maybe it's because there are dozens of fertile fields of growth still to explore. Regardless, all-star investors bet on growth over the long haul because:

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
Not all growth stocks will do. Our weekly hunt is for 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 the Motley Fool CAPS investor intelligence database.

Specifically, we're looking for stocks that are expected to grow earnings by an average of at least 20% annually over the next five years and which have earned a five-star rating in CAPS. 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. Among the list, nanoscale tool maker Veeco interests me most. Why? One reason is the firm's triple-digit earnings growth.

Then there's the all-star effect. Nearly 40% of those rating Veeco are All-Stars, or investors who rank in the top 20% of the CAPS database. Every one of them says the stock will outperform.
