Simple Diversification
Better known as “don’t put all your eggs in one basket.” You’ll do better in a variety
of assets because one will surely be going up when another is going down.
Successful investing requires more than taking risks to get an expected return. It also means
reducing risks that do not. Avoidable risks include holding too few securities, betting on
countries or industries, following market predictions, and speculating on “information” from
rating services. To all these, diversification is the antidote. It washes away the random
fortunes of individual stocks. It positions your portfolio to capture the returns of broad
economic forces.
For many investors, the S&P 500 represents the first equity asset class in a diversified portfolio.
Although the S&P 500 Index is diversified in large US companies, investors can benefit further by
adding asset classes. Take, for example, a portfolio that holds just US stocks (S&P 500 Index), a
portfolio that holds just Japanese stocks (MSCI Japan Index), and a portfolio that holds both.
The portfolio that holds both has not only provided a higher historical return than
either alone, but it has done so with fewer negative quarters.
