There are 353 stocks that would have earned you greater than 20% annualized returns from 1997 through 2006. 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 1997 through 2001:

Each of these companies would have earned you greater than 20% annual returns during the past 10 years, yet none beat the market every year. There was only one year when all seven of them increased in value, and there was not one year when all 353 of the market's best increased in value.

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

How many folks dumped Constellation Brands after it seemed to stagnate in 1998 and 1999? They've missed out on good growth since then. And how many are dumping the stock now, after the winemaker recently warned of slower growth? This volatility won't last forever.

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.
