I'm a believer in growth stocks. As an analyst for our Motley Fool Rule Breakers service, I think you should be a believer, too. But even I have to admit some growth stories are bogus, hence this regular series. We'll be taking a closer look at many of the market's great growth stocks to see which of them show real, numerically relevant signs of sustainability.

Next up is Rackspace Hosting (NYSE: RAX), a data-center operator that's adding thousands of clients to its cloud-computing servers each quarter. If that sounds like a pedestrian business with an indefensible moat, it is. And isn't.

Rackspace makes its living providing the best support in the business. "Fanatical support," the company calls it, with the idea being that no customer can ever be too satisfied with their experience. And that level of commitment has created as many Rackspace fans as customers.

Fools are also fans, and for good reason. Company insiders still own more than 22% of the business, according to Capital IQ. Company chairman Graham Weston, one of Rackspace's earliest investors, owns a little less than 16%.

Rackspace is also attracting some of the best talent in the business. David Kelly, the company's new head of international operations, has experience with both Amazon (Nasdaq: AMZN) and eBay.

"Quality management is of paramount importance to Foolish investing, and Rackspace is certainly doing its part to stay on top of the game," wrote my Foolish colleague, Anders Bylund, in rating the stock in Motley Fool CAPS.

The elements of growth

There's a lot of good news in this table. Let's review:

  • Rackspace has accelerated net income growth since 2008. Sustained, long-term improvement like that is exactly what we growth investors love to see.
  • Even better, growth hasn't come as a result of price cuts. Volume sales in low-cost cloud computing services have kept margins high.
  • Finally, take a look at the receivables growth. Not only is revenue growing faster than receivables today, reversing a trend from 2008, but the gap between revenue and receivables growth is also widening. This business gets more efficient with each passing year.

Rackspace hasn't been public for long, thus its lack of a long-term track record for normalized net income growth. But it would be a mistake to write off this Rule Breaker because of its short time dancing with Mr. Market.

Why? Loyalty and focus. Rackspace has loyal fans as customers and management is focused on producing the highest possible returns on its available capital. They've been successful so far; ROC has improved steadily since 2008.

Grade: Sustainable
I've twice recommended Rackspace to our Rule Breakers subscribers, and I've seen nothing to shake my conviction that this is a long-term winner in the making.
