Where were you in August 1994, and what were you doing? When I tell you where I was, you won't believe it (of course, you'll have to read to the end to find out).

You were at least buying stocks, right?
I wasn't. I sure as heck wasn't gambling $1,800 on a company you'd never heard of. But somebody was, and he was about to make a lot of money. I know this for two reasons.

First, that one trade made this guy a local legend. Second, this Fool shouted his intentions before he went long, then tracked his returns online for all of us to see.

Five years later, his split-adjusted $0.46 shares crested atop $50. Before you could say "Mad Money," Money.com called him "among the most widely followed stock market advisors in the world," and his $1,800 stake ballooned to $190,000.

Yes, you read that right
That stock was America Online -- and the "guy" was David Gardner. Granted, we were in a massive bull market, and that helped. But AOL was also a first-mover in an emerging industry that was about to change our lives. And this may surprise you. David's AOL investment is still up. Way up.

If you'd bought AOL with him, you'd be up 4,000%. Or maybe you didn't see the Internet coming? Maybe, like me, you thought the future was biotech. I was stunned discover that Biogen Idec (NASDAQ:BIIB) had performed even better over the same period, up some 14,000%, and that Genentech (NYSE:DNA) was up more than 1,000%.

Even if you rolled the dice on old-school EMC (NYSE:EMC) or Cisco Systems  (NASDAQ:CSCO), a former tech darling once held up as a poster child for the tech stock bubble, you'd be up high triple digits -- way ahead of what you'd expect from non-equity investments.

I'm shocked, shocked to hear ...
Maybe that doesn't surprise you, but it surprised me. In fact, it has me revisiting two long-held beliefs. The first brought an affirmation, but the second was an epiphany. First, the affirmation.

As people who want to save for their future approach middle age, they have to invest. For me, that means buying stocks, whether they look overvalued or cheap -- and not selling. That last part goes double whenever we manage to catch lightning in a bottle. And it does happen.

After all, AOL isn't David's only great call. He also told me about Marvel Entertainment (NYSE:MVL) before Spider-Man and game developer Activision (NASDAQ:ATVI). Both are up more than 400% since then. But take away the 4,000% winner, and David looks downright human, right? Well, yes and no. More on that just ahead.

But first, the epiphany!
Slow and steady may not win the race. As you know, I typically side with David's stodgy brother Tom -- citing data supporting Warren Buffett's steady-as-she-goes, win-by-rarely-losing value approach.

But I wonder: What if David's right to point out that on most nights, we only need a few big swings to win? Or, put another way: Nine out of every 10 stocks we buy can go to absolute zero and we'll still break even if we find just one 10-bagger.

And that's a 10-bagger -- a solid 1,000% gainer. Now, what if you smack a 4,000% home run? I'll let you run the numbers.

Because I have news for you ...
"The Tortoise and the Hare" isn't a true story. It's not even based on one. Take away AOL, Marvel, and Activision ... and David's pretty average. But that's crazy talk. You don't compare the batting average of a singles hitter with that of a slugger.

The fact is, David's kamikaze style works over the long run. And not just in the '90s. To prove it, David launched his new Rule Breakers newsletter in 2004 to find this decade's great growth stories. How does he do it? It's part science, part art. But he starts with a six-point checklist:

  1. Is it the top dog and first-mover in an important, emerging industry?
  2. Does it have a sustainable advantage?
  3. Does it have strong past price appreciation?
  4. Is good management in place with smart backing?
  5. Does it have strong consumer appeal?
  6. Has it been called overvalued by the media?

A stock with all six of these traits is a Rule Breaker in the making. In fact, three of David's newsletter picks have already tripled in value, including the red-hot Intuitive Surgical, which is up 370% since March 2005.

If any of this strikes you as intriguing, here's a suggestion. You can use David's six-point checklist to get started.
