Why Diversify?
Here are several "periodic tables" that show how various asset classes performed over the past two decades. The Canadian tables show returns in CA$ and the US tables in US$.

Note that there is no discernible pattern as to which asset classes would outperform each year. Moreover no one was able to consistently predict the best asset classes for each year. These observations make a strong argument that one should diversify broadly among all major asset classes rather than try to guess which ones will do best every year.

If not, then consider a diversified portfolio rather than gambling on picking next year's winner."

"Why Diversify" [Franklin Templeton] "It's next to impossible to find any pattern in the past 20 years that will have any predictive value for the next 10 or 20 years. The rise and fall of different asset classes appears to be totally random."

Periodic Table of Investment Returns [Callan Associates] is a "representation of relative asset class performance over the last 20 years... ranked from best to worst. Each asset class is color-coded for easy tracking. Well-known, industry-standard market indexes are used as proxies for each asset class."

The Importance of Diversification [Allianz Global Investors] "From year to year, there’s no telling which asset classes will be the best performers—a strong argument for portfolio diversification. The chart below ranks the best to worst performing asset classes from top to bottom for the years 1997 to 2006."
