The Death of Diversification

I’ve got three words for you: “Diversification, Diversification, Diversification!”

Since the dawn of Modern Portfolio theory, the benefits of non-correlation with favorable impact to risk and return have created a mantra for investors. At Center for Financial Planning, we agree!

We’re not alone. As I worked on this blog, I did a quick Google search for diversification and investing. At the top of the list was a post from the SEC on “The Magic of Diversification”. Here’s an excerpt:

At this point, the mantra is ringing in your head and you’re saying, “Yes! I know this. This is a fundamental lesson for investors.”

But, wait! In 2011, diversification largely left investors begging for more. A plain vanilla, decidedly undiversified mix of the S&P 500 and Bar Cap Aggregate bond indexes outperformed a more broadly diversified mix of assets including portfolios that included international investments, small company stocks, diversified types of bonds, and commodities.[1]

What’s an investor to do? As with anything, no investment strategy is foolproof including diversification, especially in the short run. But what your heart tells you in a period of underperformance is to stick with what’s worked recently (or bail on the mantras if they aren’t working right now). This time is different! After all, Europe looks scary! Historically, periods of diversification underperformance have been followed by outperformance. Investment thinker Robert Arnott of Research Affiliates tracks a diversified portfolio of 20 asset classes. After the 3rd quarter of 2011, the year’s worst, Arnott noted the significant underperformance of his diversified benchmark as compared to a 60/40 S&P/Bar Cap Agg portfolio.

The question for investors today is what may happen going forward. Past performance cannot predict future turns. Arnott notes, though, that in the past, following significant periods of underperformance for diversification, diversified portfolios have outperformed.

Their markets are likely to be volatile and there may be sharp price fluctuations even during periods when prices overall are rising.  Dividends are not guaranteed and must be authorized by the company’s board of directors.  Every investor’s situation is unique and you should consider your investment goals, risk tolerance and time horizon before making any investment.  Investing involves risk and you may incur a profit or loss regardless of strategy selected.  The foregoing is not a recommendation to buy or sell any individual security or any combination of securities.
