Why is Portfolio Diversification Important?

January 08, 2016 | Mike Spychalski, CAIA, Vice President

This week’s Chart of the Week shows what is commonly referred to as a “Periodic Table of Investment Returns.” It is a table showing historic calendar year returns for various asset classes ranked in order of performance from best to worst. One of the key takeaways from this table is that 2015 was a particularly challenging year for investment returns. With the exception of real estate, there were no major asset classes that posted double-digit gains in 2015, and except for emerging market equities, there were no major asset classes that posted double-digit losses for the year. In an environment where most asset classes posted low single-digit returns for the year (either positive or negative), it was extremely difficult for diversified portfolios to achieve their target rates of return in 2015.

The other key takeaway from this table is the importance of diversification within a portfolio. As seen in the table, there has been very little consistency in the best and worst performing asset class from year to year. In fact, since 2007 just about every asset class that was the best performing asset class for a year was also the worst performing asset class for a year during this time frame. Just because an asset class performs well in one year it will not necessarily perform well the next, and just because an asset class performs poorly in one year it will not necessarily perform poorly again the next. This illustrates the importance of adhering to strategic asset allocation targets and rebalancing portfolios back to targets over time.
