I lived through Hurricane Andrew in 1992. It was only the third Category 5 storm to make landfall in the United States, and it was a doozy. I remember waiting for the deafening gusts to subside before venturing out to see the savage destruction that the killer storm had caused. When it comes to windstorms, Category 5 is as intense as they get. When it comes to investing, growth stocks would be the market's equivalent.

Growth stocks are powerful, which can sometimes be a good thing. Find the right stock on the cusp of blowing apart the landscape, and you can go from being a modest investor to a rich one in the blink of a hurricane's eye. Think Intuit (NASDAQ:INTU) just as it was about to hit a nerve with mainstream audiences through simplified tax filing and small-business accounting software. Delve into AMD (NYSE:AMD); the gutsy chipmaker defied convention and had the gall to take on the mighty Intel (NASDAQ:INTC) -- and showed that it can hold its own in the industry.

By the same token, growth stocks are volatile. I saw it when I stepped outside of my home in 1992. You can see it, too, in a portfolio ravaged by the wrong growth stocks. Planet Hollywood? 3DO? They both blew my portfolio to pieces way back when.

Bracing for the big one
Snapping up the right growth stocks is the aim of the Motley Fool Rule Breakers newsletter service. Every month, David Gardner leads a team of analysts in unearthing a couple of ultimate growth stock ideas. When he's right, Category 5 investing can be a thing of beauty. Four of the 24 recommendations from last year have gone on to more than double. Three have more than tripled in value! When he's wrong, the damage can be brutal. More than half of this year's picks are sporting double-digit losses.

The key to aggressive growth stock investing is to let your winners run. If you land that 10-bagger, it means that nine other similar investments can go to zero and you'll still have broken even.

Taking chances has led the service to single out some pretty eclectic -- if not outright eccentric -- companies. SonoSite (NASDAQ:SONO) is a cutting-edge medical equipment company that is carving itself a niche by making ultrasound gear portable and accessible. LoopNet (NASDAQ:LOOP) is looking to tap the power of the Internet to rethink the way we trade commercial real estate.

Buying into new technology is risky. In fact, both of these stocks are trading for less than they were when the companies were first recommended. That's OK. Disruptive technology may not disrupt overnight, but when it does, the upticks can come in a hurry.

I am fortunate enough to have been with The Motley Fool in the mid-1990s, when David was recommending the purchase of companies like Time Warner's (NYSE:TWX) America Online, Iomega, and Amazon. They seemed like radical investments at the time. AOL was battling it out in the cutthroat realm of dialup online services. Iomega was a tired data-storage company betting big on its proprietary Zip disk product. Amazon was trying to turn retail distribution upside down by shipping book orders placed online directly to the end user. AOL, Zip, and online shopping took off, and so did David's real-money Rule Breakers portfolio.

Andrew, 14 years later
The storms keep coming. I still live in Miami, so I've had my share of windstorms come by in recent years. Last year, Katrina and Wilma came for a visit, and the alphabet is still young in 2006.

Storms continue, but so do investing ideas. Over the summer, I looked at investing styles and labeled them as hurricane categories.

Wrapping things up with the most powerful -- and sometimes dangerous -- basket of stocks makes sense. I'm part of the Rule Breakers team of analysts. I buy stocks in all shapes and flavors, though I'm always smitten by a good young growth stock with a great story to tell.

Oh, they do tell stories. It was easy to snuggle up to Akamai (NASDAQ:AKAM) -- an active Rule Breakers recommendation that is on the cusp of quadrupling and that I regrettably sold way too soon -- as chunky digital files play into its strength as the top dog in digital delivery.

I'll probably continue taking chances in my portfolio in the coming weeks. I don't mind the exotic. I don't fear Category 5 investing. I've seen David excel at it for nearly as long as I've been telling stories of how I made it through Hurricane Andrew.
