Does a 60/40 Portfolio work in retirement?

“Tim, I’m diversified, I have a 60/40 portfolio.” This is a conversation had in our conference rooms 100’s of times over the last 25+ years. I am a statistics guy and a history buff. Let’s take a look at what history says about “I’m Good”…


During the short nine days of trading from late January to February 8, 2018 the S&P 500 fell like a skydiver leaping out of a plane: fast and down. In a classic flight-to-quality response, investors pulled their parachutes, socking billions into the largest ETF's tracking the widely-watched Bloomberg Barclays U.S. Aggregate Bond Index (the “Barclays Aggregate”). This time, though, it didn’t work.

What if, when skydiving, your parachute fails to open? In an epic fail of financial engineering, both the broadest U.S. stock and the standard fixed-income benchmarks declined during this first correction of 2018.


Conventional thinking says that stocks and bonds tend to behave in opposite ways, when one goes up the other goes down. This “negative correlation” offers a “parachute of safety” and easy diversification over time, making a default to a 60/40 (60 percent stocks and 40 percent bonds) portfolio a prudent way to invest over time.


Or does it?


The delusion that a 60/40 portfolio protects an investor has to be put in context. For the past roughly 20 years, stocks and bonds have generally demonstrated negative correlation. During the 1970s into the mid-1990s, though, the exact opposite was true, so holding the Barclays Aggregate as a shield against risky stocks just didn’t work.


Tightening Fed policy, inflation, rapidly growing deficits and their impact on rates can sometimes move bond prices violently. July 2016 marked the lowest level in rates I will likely see in my lifetime. If interest rates continue the climb up from that level, traditional bonds and the 60/40 allocation will continue to die, as foreshadowed during the first correction of 2018.


The pace of rising rates may be a “known unknown.” Adding to the risks is the sharply higher interest rate sensitivity of the Barclays Aggregate, where duration is now at a 30-year high (see chart) . Think of it this way: a 1% rise in rates knocks about 6% off the price of the benchmark and takes 28 months to recover, at current yields. Ten years ago, that same 1% rise in rates clipped only 3.75 percent off the price with less than 12 months to recover (at prevailing rates at that time). Most investors are not aware of the current riskier profile of this “low-risk” benchmark.


The U.S. bond market is twice as big as the U.S. stock market, but bond portfolio construction garners far less attention than stock construction. In fact, there were plenty of fixed-income “parachutes” during the first correction of 2018, but they aren’t components of the Aggregate. Floating rate loans, for instance, held up in positive territory, but have a zero allocation in the benchmark.

Managing risk is harder than ever and the occasional positive correlation between stocks and bonds doesn’t help. In all likelihood, you own a fund that follows the Barclays Aggregate, but life isn’t passive. Your bond manager shouldn’t be either.


Tactical management and the manager’s ability to go to cash as an option is the hinge pin that can swing the door of downside risk protection. It’s not that these managers are right all the time, in fact, in many cases they are wrong 30-40% of the time. However being right 60-70% when mixed with different managers with different return patterns can result in historically low correlation to the market downside, while achieving an acceptable amount of upside return.
