Volatility & Diversification
B
y seeking diversification, investors try to reduce risk, increase returns, or ideally, achieve both. Unfortunately,
many investors take the wrong approach to accomplishing these goals. For years, the focus for diversification
has been largely one-sided, with a large emphasis on risk reduction at the expense of the entire portfolio. In
focusing solely on risk reduction, investors tend to seek low-volatility investments in order to moderate the
swings of their equity-heavy exposure.
This method of diversification is likely the result of misinterpreting
research that began in the 1950s by Harry Markowitz with his premise of Modern Portfolio Theory.
In his research, Markowitz introduced the idea of The Efficient Frontier, where incrementally adding a highervolatility asset class into a lower-volatility portfolio may have the ability to reduce risk and increase returns.
Specifically, Markowitz showed how a portfolio of bonds could add an allocation of higher-returning, morevolatile stocks and the effect would be to greater returns with less risk.
The image below shows the basic concept of Modern Portfolio Theory and the Efficient Frontier. It is a
hypothetical illustration of adding stocks in 10% increments to a bond portfolio. Along with returns increasing,
it is important to notice that risk is initially reduced to the left before curving back to the right as the allocation
to stocks becomes over-weighted.
For a bond investor seeking greater returns, but who does not want to accept
greater risk, incrementally adding a portion of stocks may prove to be more optimal over time.

Hypothetical illustration
. It seems that many of today’s investors have it backwards. They start with a risky portfolio, largely comprised
of stocks, and try to add less-volatile assets to reduce risk—and they are often surprised when they also get less
return. It would benefit them to heed Markowitz’s guidance. His objective was to lower risk and increase returns by
adding higher-volatility asset classes with strong return characteristics.
How can adding a volatile asset class such as stocks reduce the risk of a bond portfolio? Most would think
that adding stocks would raise the average volatility of the combined portfolio.
But it doesn’t. That’s because of
correlation—which measures the relationship of two investments. The lower the correlation, the greater the chance
for an asset to provide diversification benefits.
And if investments are going up and down at different times, some
of the volatility is cancelled out.
The images below illustrate the impact of adding high-returning, high-volatility assets incrementally to a portfolio.
If an asset is highly correlated, there will be little or no curve in the frontier—rather, a straight line will form with
each allocation, and risk is increased along the way (left image). Provided the high-volatility asset has very low
correlation, the curve will be more dramatic, initially reducing risk before it begins increasing (right image). The
idea is to find an optimal point where the risk/return level matches an investor’s risk tolerance and objectives.

Quick “CAR” Test:
Correlation-Adjusted Risk
A simplified “quick check”
when comparing investments
with similar risk/return
characteristics is to multiply
the standard deviation by the
correlation to a benchmark
(like the S&P 500 or a core
portfolio).
The one with lower resulting
CAR score should offer a hint
towards the investment with the
greater diversification potential.
Summary: Not all high-volatility assets are the same.
Some high return/high volatility investments—such as
international companies, emerging markets and sectors like technology—also have periods of high correlation to
domestic stocks, especially during periods of market stress. But there are some—managed futures, commodities
and REITs, for instance—that have a history of maintaining low correlation to domestic stocks, even during
market stress. In fact, the more volatile and less correlating an investment is relative to a core portfolio, the less of
it you have to use to receive the potential diversification benefits.
When used in concert with correlation, highvolatility assets may enhance returns and lower risk in a well-diversified portfolio.

Traditional, nontraditional
and alternative investments involve risks, including the potential for loss of principal. Nontraditional and alternative
investments may involve additional risks, including, but not limited to, shorting risks, the use of leverage, the use of derivatives, futures
market speculation and regulatory changes. Before investing in any financial product, always read the prospectus and/or offering
