I lived through Hurricane Andrew in 1992. It was only the third Category 5 storm to make landfall in the United States in recorded history, 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 Callaway Golf (NYSE:ELY) just as oversized golf-club maker was rolling out its revolutionary Big Bertha driver. Delve into Research In Motion just as the first of its Blackberry mobile devices hit the market, or Herman Miller (NASDAQ:MLHR) just as the office specialist was inventing the now-dreaded cubicle, or the more modern Aeron office chair.    

By the same token, growth stocks are volatile. I saw it when I stepped outside 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 2005 have gone on to more than double. Two have more than tripled in value! When he's wrong, the damage can be brutal. Eleven of last 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. Steiner Leisure (NASDAQ:STNR) has more than doubled as the spa services provider of choice on nearly every major cruise ship. Companies like Carnival (NYSE:CCL) keep tacking on more -- and larger -- ships to its fleet, growing Steiner's fan base. LoopNet (NASDAQ:LOOP) has held firm even as most real estate plays have gone sour, thanks to its growing popularity in the more stable commercial real estate market.

Earlier this year, the newsletter also landed a potential winner in Mindray Medical (NYSE:MR). China's largest medical-device maker has a healthy home market to serve, yet Mindray is also shipping out its wares to 120 different countries.

Buying into relaxing massages, electronic realty exchanges, and electrocardiogram makers can be risky. That's OK. Disruptive technology may not disrupt overnight, but when it does, the upticks can come in a hurry.

I'm fortunate enough to have been with The Motley Fool in the mid-1990s, when David was recommending the purchase of companies like America Online, PayPal, and Amazon.com. They seemed like radical investments at the time. AOL was battling it out in the cutthroat realm of dial-up online services. PayPal was battling established financial services titans in the field of online micropayments. Amazon was trying to turn retail distribution upside down by shipping book orders placed online directly to the end user. AOL, PayPal, and online shopping took off, and so did David's real-money Rule Breakers portfolio. 

Andrew, 15 years later
The storms keep coming. I still live in Miami, so I've had my share of windstorms come by in recent years. Two years ago, Katrina and Wilma came, and this year's season, starting in June, is forecasted to be very active.

This past summer, I looked at investing styles and labeled them as hurricane categories.

Wrapping things up with the most powerful -- and sometimes deadly -- 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 a company like Steiner, one of the earliest Rule Breakers recommendations. I made the pick after watching cruise industry trends evolve over the years. It was no longer an elderly crowd lining up for shuffleboard. The sector was attracting a younger, self-aware audience through a growing number of ports.

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.
