Just like folks who go fishing, investors love to tell tales of "the one that got away."

We speak remorsefully about the stocks that could have, would have, or should have made us a fortune -- if only we had made an investment.

Maybe you were an early customer of Green Mountain Coffee Roasters (NASDAQ:GMCR) or a die-hard Apple fan, but you didn't invest in either company back then. Now, every time you hear that they're two of the market's 10 best stocks from 1998 to 2007, you wish you could time-travel back to 1998 and invest $1,000 in each company. Today, those tiny investments would be worth $37,810 and $11,600, respectively.

Sadly, the flux capacitor is fictional.

Mustard seeds
"The stock that got away" is usually a small company that made it to the big leagues. That makes sense, because those are the stocks with the most room to grow. You simply don't hear stories about people missing the boat on megacaps such as DuPont (NYSE:DD) -- unless the storyteller was born in 1902.

That's because, although large companies such as these may have many years of steady growth ahead of them, their high-growth stages have long since passed.

Johnny-come-lately
One of the worst things an investor can do is invest in "the stock that got away" after it has reached large-cap status, in hopes that it will repeat its past performance. The law of diminishing returns makes such a feat difficult to achieve.

Consider:

Stock

Return 1988-1998

Return 1998-2008

Cisco Systems (NASDAQ:CSCO)

23,450%*

(12%)

Medtronic (NYSE:MDT)

3,178%

(3%)

Amgen (NASDAQ:AMGN)

2,750%

195%

Lowe's (NYSE:LOW)

1,698%

105%

As you can see, even with good results like Amgen's, there's a stark difference between the stocks' most recent 10-year returns and their previous 10-year returns.

Catch the next one
The good news is there's no need to dwell on "the stock that got away." Tomorrow's big catches are out there right now, masquerading as small caps. The problem is, it can be hard to locate tomorrow's winners among the thousands of small companies on the market, especially with all the market turmoil we've experienced. But the down market makes the search for great small companies even more exciting, because some of the best companies of the next 10 years are trading at great prices right now.
