Congratulations! Your portfolio is perfect. The collection of companies that you have assembled is ... mwah, tresmagnifique -- 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. It is, however, the best way out.

When you think about it, investing is just like that. Even if your portfolio is heavily weighted toward a particular sector, or if there is 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 motorcycles, Harley-Davidson (NYSE:HDI) comes to mind because it's been the leading brand for most of its 103-year history. Even in a sleepy sector like memory chips and cards, which seem like little more than low-margin commodities, a company like SanDisk (NASDAQ:SNDK) can become a 10-bagger over the past 10 years simply by being the brand that matters and staying at the leading edge of its industry.

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 what our Motley Fool Rule Breakers newsletter service aims to achieve. It's not an intimidating process. Who here didn't know that companies such as Omnivision (NASDAQ:OVTI), with its camera-phone sensors, and Internet speed freak Akamai (NASDAQ:AKAM) were up to something special with their technology early in their tenure? 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
Akamai has been on a tear since being singled out to Motley Fool Rule Breakers subscribers last year. The shares have soared 150% higher in that time, as the company continues to grow its presence in the field of accelerating online content delivery.

We're not just talking growth here. We're talking about accelerated growth. In 2003, revenue rose a mere 11% at Akamai. The quality of its ability to deliver content like software updates for Microsoft (NASDAQ:MSFT) or digital downloads for songsmiths like Apple Computer (NASDAQ:AAPL) and Napster (NASDAQ:NAPS) has never been in doubt. Companies were just tenuous about ramping up their budgets and allowing Akamai to come in and speed up the secure transactions.

Times have changed. In 2004, revenue roared 30.2% higher. Last year? The company's top line surged 34.8%.

That's called accelerating sales 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. 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% growth 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.

The stock pick of the litter
Another recent accelerator has been iRobot. The leader in consumer robotics, with its Roomba vacuum-cleaning automatons and now its Scooba floor-scrubbing saviors, has been growing awfully quickly in recent years. In 2004, the company generated 75% more in revenue than it had in 2003. Last year, it felt as if the company was coming back down to earth with a more modest -- yet still impressive -- 49% improvement in sales.

Now we find the company reporting first-quarter results for 2006 that have revenue soaring 123% higher. Even if it's ultimately a blip in a traditionally sleepy period, it starts the company on the right foot this year.

Akamai and iRobot share something else beyond a refreshingly potent case of accelerated growth. Both stocks were singled out last 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 (like Apple with its iPod) or a promising upstart bent on rewriting the rules (like iRobot), knowing a little about the disruptive shift that is taking place helps. However, you can always lean back on the income statement. Organic acceleration in sales growth is nothing to scoff at.
