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 satellite television gurus DirecTV (NYSE:DTV) and Dish parent EchoStar (NASDAQ:DISH) when most couch potatoes were still associating satellite television with huge reception dishes the size of boats. Imagine buying into Adobe Systems (NASDAQ:ADBE) just as the publishing software was starting to make waves as editorial departments took to the high-margin goodness of cyberspace distribution.   

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. Six of the 24 recommendations from 2005 have gone on to more than double. Four have more than tripled in value! When he's wrong, the damage can be brutal. Nine 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. Chipotle Mexican Grill (NYSE:CMG) has rolled roughly 75% higher since being singled out earlier this year. The company's burrito-powered success has come even as other Fresh Mex chains such as Baja Fresh and La Salsa have gone the other way.

Robotics specialist iRobot (NASDAQ:IRBT) is another intriguing storyteller. The stock may not be a hot tamale like Chipotle, but the fellow recommendation is doing some pretty amazing things both on the battlefield with its unmanned military robots and at home with its Roomba automaton floor suckers.

Buying into fast-food chains and programmable robots can be risky. That's OK. Disruptive technology may not disrupt overnight, but when it does, the upticks can come in a hurry. It's better to be early -- like buying into Crocs (NASDAQ:CROX) before it was cool to have holes in your shoes, even if they were the most comfortable things on the planet -- than late, like buying Heelys (NASDAQ:HLYS) after the last of the parents have been scared away after a litany of safety warnings.

I'm fortunate enough to have been with The Motley Fool in the mid-1990s, when David was recommending the purchase of companies such as 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 Breaker 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 is an active one so far. 

Last 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.

I don't mind the exotic. I don't fear Category 5 investing.
