This is as important a lesson as there is in the stock market, and it's a particularly important lesson to heed today. It's simply this: The stock market is volatile, but volatility does not prevent you from earning great returns.

See, there are 271 stocks that would have earned you more than 20% in annualized returns from 1998 through 2007. The one trait they have in common is their unpredictability.

The numbers story
With these stocks, a buy-to-hold strategy would have earned you massive returns, but you'd have had an unsteady ride. It was loss one year and huge gain the next. Consider these examples from 1998 through 2002:

Each of these companies would have earned you greater-than-20% annual returns during the past 10 years, yet not one went up every year.

What does this tell us about earning returns for 10 years or more? It tells us that we need to be patient. Our best move today is to buy good companies with bright futures and hold them, despite inevitable market volatility.

How many folks panicked and dumped Sigma Designs when it dropped 90% in 2000, or Urban Outfitters when it declined 71% that same year? Both would have turned out to be bad decisions.  

Market-beaters of the future
One year isn't long enough to judge an investment thesis. That's why real gains are made by folks who identify opportunities, grab them, and hold on to them. Master investor Warren Buffett readily admits that his incredible portfolio would be better off today if he'd never sold a single share.

Fool co-founders David and Tom Gardner have made it their mission to identify market killers for Motley Fool Stock Advisor subscribers for the next 10 years. They can't predict whether their recommendations will go up or down in any given year (though this is looking like a down year), but they are confident in their long-term prospects.

The market's greatest gains from now until 2018 will be made by investors who can be patient.
