One thing that often gets lost in all the talk of sizzling stocks and 20-baggers is the benefit of diversification. It's a concept every investor can understand and profit from.
And don't think diversification automatically means mediocre returns. David and Tom Gardner have led Motley Fool Stock Advisor members through a variety of industries, and even some international exposure, on the way to outsized performance (70% total average returns versus 30% in the S&P 500). So it can be done.
You, too, can construct your portfolio in a way so sensible that you significantly lower your risk -- even if you own very few stocks. Here's how.

Always try to consider how each potential new purchase relates to the rest of your portfolio. If Toyota
The next logical step, then, is to aim for great stocks with a low or negative correlation. That simply means that although they'll all hopefully rise in value over the long term, they will tend to move in relatively different directions along the way. One zigs, the other zags, and your portfolio's returns will be much smoother as a result.
The best news is that it's fairly easy to gain this benefit. In his classic book, A Random Walk Down Wall Street, Princeton professor Burton Malkiel notes that "anything less than perfect positive correlation can potentially reduce risk."

Such stocks are among the market's best performers when the turnaround comes, as it inevitably does in a relevant industry. Think of how companies in the investment sector like E*Trade
When the Stock Advisor service began in early 2002, Tom saw value in the financial and business services sector, and picks like Moody's
Let's take a look at two of his stocks from different industries, to highlight the diversification benefit. BorgWarner supplies powertrain parts to auto manufacturers. Quality Systems
I don't use these examples to applaud Tom and David's stock-picking skills. Rather, my aim is to highlight the importance of diversification, even when choosing a relatively small number of stocks. Certainly, not all stocks will be winners. But by spreading picks across sectors, you're giving yourself a chance for sensible diversification and a smoother road to long-term success.
