Congratulations! Your portfolio is perfect. The collection of companies that you have assembled is ... mwah, tres magnifique -- the perfect combination of bottle rocket and short wick. Celebrated investors like Warren Buffett, Peter Lynch, and David Gardner have you on speed dial. Riches beyond measure are just a few trading days away.

Now, I'd love to tell you that with a straight face. Really. I'd love to deny that I saw you nodding along with me just now. It's human nature, really. Every investor thinks he or she owns the best stocks. It's a bit like rooting for your alma mater's football team or cheering on that lottery ticket or roulette wheel. You think you've got a fighting chance to win -- or you wouldn't be there at all.

It's not hopeless. Beating the market is a lot easier than you think. It's just a matter of identifying the great growth stocks of tomorrow before the rest of the market comes around. Sound daunting? It isn't, really.

Best of breed in a flea-ridden world
By now, you've probably heard the expression "best of breed" countless times -- and you're probably wondering what it's all about. In the corporate software space, the phrase refers to cherry-picking the best applications that excel at a particular task. Instead of resorting to the integrated one-vendor solution suite, you assemble a hodgepodge of specialized brands. It's not the easy way out, but it is the best way.

When you think about it, investing is just like that. Even if your portfolio is heavily weighted toward a particular sector, or if there's a theme that resonates throughout your holdings, every stock you own is unique. To you, it was the best of its breed.

"Best of breed" has evolved in recent years. These days, it's the process of ferreting out the superior company in a particular sector. If you're talking about portable communication, Research in Motion (NASDAQ:RIMM) is probably the first company that comes to mind. The BlackBerry maker saw revenues surge 65% higher this past quarter. Investors are rightfully skittish about the company's prospects once Apple (NASDAQ:AAPL) rolls out its versatile iPhone next month, but BlackBerry is still the brand that matters. Can you name another video game retailer after GameStop (NYSE:GME)? Me neither. If it exists, GameStop is probably on its way to acquire it.   

The market rewards excellence. That's why finding these top performers is often a financially rewarding quest. What could be better than that? Well, for one, identifying these best-of-breed companies just as they begin to shine.

Finding great growth stocks early is the goal of our Motley Fool Rule Breakers newsletter service. It's not an intimidating process. Who here didn't know that SanDisk (NASDAQ:SNDK) had the inside track on cashing in on the consumers' migration to flash memory storage solutions? Who here didn't know that Harley-Davidson (NYSE:HOG) would rev up shareholders with decades of market-thumping gains on the strength of its iconic motorcycles? However, even if you weren't familiar with their models, you still could have warmed up to their income statements.

Decelerate at the sign of acceleration
Under Armour
is a recent pick for Motley Fool Rule Breakers subscribers. You may know it for its moisture-controlling clothing, which has taken pro sports by storm. Last year, it made the bold move of entering the athletic footwear market with its "click clack" cleats. Don't diss the shoes. Some of the market's best performers in recent years have been hot footwear makers.

How could investors have spotted something special in a company that specializes in outfitting winners on the playing field? You didn't have to dig a whole lot deeper than the top line here.

In 2005, Under Armour's revenues climbed an impressive 37%. Last year found the company going significantly higher. Back in July, it delighted investors with the news that it would be growing its top line by roughly 46% in 2006. Things got even better in the second half of the year, with Under Armour's revenues ultimately marching 53% higher in 2006.

That's called accelerating growth. You just don't see it very often. Logic would dictate that as a company grows, it does so off a larger base of sales and earnings. That makes growth, on a percentage basis, more difficult to keep up with. Let's say a company produced revenue of $50 million one year, then $100 million the next. That's a cool 100% increase in revenue. If it clocks in at $160 million the following year, that $60 million more in sales is even better than the $50 million it generated a year earlier. However, on a sales-growth basis, it would simply mark a 60% improvement from the previous year's $100 million sum.

Sometimes accelerating growth shows its welcome face over the course of a single year. Let's take a look at how online retailer (NASDAQ:AMZN) grew its top line last year:

Year-Over-Year Sales Growth

Q1 2006


Q2 2006


Q3 2006


Q4 2006


20%? 22%? 24%? 34%? It's a welcome trend, especially as the company headed into the seasonally potent holiday quarter. As big as Amazon is, the leading e-tailer is growing faster than a more nimble player like apparel specialist Bluefly (NASDAQ:BFLY).

The stock pick of the litter
A recent top-line accelerator is Secure Computing. The computer security specialist had a respectable year in 2005. It grew revenues by 17% as companies took to Secure's online solutions.

Things got dramatically better in 2006. Secure Computing's top line soared 62% higher.

Under Armour and Secure Computing share something else beyond a refreshingly potent case of accelerated growth. Both stocks have been singled out over the past year as Rule Breakers recommendations.

Of course, it helps if you understand why growth is accelerating. Whether it's an established company with a suddenly vibrant new product (iPod, anyone?) or a promising upstart bent on rewriting the rules (like Amazon), knowing a little about the disruptive shift that's taking place helps. However, you can always lean back on the income statement. Organic acceleration in sales growth is nothing to scoff at.
