Perspectives | A Diversification Check-Up

October 2019

Past Performance Is Not Indicative...?

Historically the monthly stock market return has been positive about 65% of the time.¹ Recently, however, a false sense of security has washed over investors. The S&P 500 has delivered a positive return in 81% of months over the past three years including multiple stretches of four or more consecutive months of positive returns.¹ The lull of a slow and steady stock market allows people to forget about the benefits of diversification – and perhaps more dangerously – mistake holding different asset classes as being “diversified.” 

Well Everyone Else is Doing It

The go-to bond investment for diversification is often an “Agg” or core bond fund that tracks the Bloomberg Barclays US Aggregate Bond Index (remember when saying the ‘Lehman Agg’ was much easier?). This has been the core standard for bond investing focused on US Treasuries, mortgages, and high-quality corporate bonds. But the bond market has changed dramatically over time. Gone are the late 1980s and early 1990s when a core bond fund delivered an 8-9% yield.²

Fast forward three decades and today investors are lucky to get a 2.5% yield (before inflation!) and significant duration (interest rate sensitivity) risk.3 A bond duration of 1 (years) generally means that if rates rise 1%, bond prices will decline 1%. Right now, the typical core bond fund has a duration of around 6 years and a yield of less than 3%. That means if rates were to rise just 1% from current levels the index would experience a roughly 3% loss or greater.³

This lower yield and higher interest-rate risk combination poses a problem as rates sit at historical lows and will likely rise over time, yet core bonds are often used as the primary or even sole bond exposure for retirees, pre-retirees and some target-date fund offerings. If you’re confident the future will mirror the past you have nothing to worry about. For the rest, it appears prudent to expand the non-equity allocation to include core-plus and multi-sector fixed income offerings. These strategies may better combat an unknown future interest rate environment and better manage fixed income risks without giving up the asset class ability to diversify equity exposure. 

Market Metrics

During the third quarter of 2019 many broad asset classes flip-flopped between positive and negative returns each month. The S&P 500 Index gained 1.7% while the small-cap Russell 2000 Index declined 2%. Trade war fears continued to spook investors as did signs of slowing global growth. Non-US equities were negative in the first two months but did rebound during September. Major bond indices were also positive for the quarter, thanks to a decline in interest rates in August. The 10-year declined from 2% to 1.5% during the first two months, settling at 1.7% to close out the quarter.⁴
