There are 271 stocks that would have earned you greater-than-20% annualized returns from 1998 through 2007. These incredible investments have a few characteristics in common. One of the most striking is their unpredictability.

The numbers story
While a buy-to-hold strategy would have earned you massive returns, it wouldn't have been a steady ride. Instead, it could have been a loss one year and a 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 just one (Gilead) went up every year (and there were only three of the entire 271 that accomplished that feat).

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 dumped CAM Commerce during the undoubtedly painful volatility of its 80% drop in 2000? The returns have been fantastic since then.

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