The traditional benchmark asset allocation is 60/40 – 60% in stocks, 40% in bonds. Such a “balanced” allocation is considered to be a moderately conservative investment posture as drawdowns in equity prices have typically been partially offset by gains on fixed income holdings. Since the financial crisis of 2008, the appetite for higher returns sparked by historically low yields on many fixed income assets may have changed that asset allocation calculus. What may appear to be nuance to some could cause a gross underestimation of risk if equity prices fall.
To explain, consider a simple proxy 60/40 portfolio. We assign the S&P 500 to represent the 60% equity component. Many investors opt for a split between the Dow, Nasdaq or Russell 2000, but for purposes of this analysis, the S&P 500 will suffice. On the fixed income side there are many types of debt securities in which to invest but for the 40% allocation we allocated 20% to U.S. Treasuries, 10% to investment grade corporates and 10% to high-yield corporate bonds.
The primary drawback of the fixed income allocation in recent years is the low yields delivered by Treasuries (end of June average 1.90%) and investment grade bonds (end of June average 3.20%). Thus, many investors have chosen to boost the income potential of their portfolios by increasing their exposure to high yield bonds (end of June average 6.05%). While done under the guise of safe fixed-income investing, this adjustment introduces a hidden risk which increases the probability of loss.

The chart above illustrates the cumulative total return profile of 3-7 year Treasuries, the S&P 500 index, aggregate corporate investment-grade index and the aggregate corporate high-yield index since December 1997. It is evident that the returns of high-yield bonds (blue) closely mimic those of the S&P 500 (red) and bare much less resemblance to the other fixed income measures. So instead of the 60/40 portfolio that many investors think they have, the reality is that the allocation described above is more accurately labeled as 70/30 and higher for those with a more aggressive high-yield allocation.
