Prudence can be a son-of-a-gun. You wear that bulky uncomfortable life jacket and never even fall off the boat. How many times have you wrinkled your clothes in the car from the snug seatbelt only to find your way safely to your destination? This is how diversifying an investment portfolio can feel sometimes. You take the sensible approach of spreading your investments over multiple asset classes only to watch as just a few of them soar, while the rest seem to drag down the overall performance in any given year.

The essence of diversification is feeling like you never own enough of the best performing asset class while always owning too much of the poorest performing asset class. Ah yes, prudence is a son of a gun. Let’s take a look at one of my favorite charts, the Asset Class Returns Quilt from JP Morgan Asset Management1. Asset classes are ranked from top to bottom by their performance during that year. For starters, I’ve isolated the years 2013 thru September 30th, 2018 to show the recent dominance of US Large Cap and US Small Cap stocks. With the exception of a 2017 rally in Emerging Markets (EM Equity) and Developed International Markets (DM Equity), it may have felt a bit silly to own anything other than US Stocks.


The natural temptation after almost 6 years of US dominance would be to trim or eliminate those investments that have underperformed and to use recent history to form an investment thesis for the future. Tempting as it may be, the evidence suggests it’s impossible to predict when the pendulum will swing the other way in favor of the next hot asset class.

Here, the same Asset Class Returns Quilt but for the period 2003-2012.


This timeframe was dominated by International Developed, Emerging Markets, and Real Estate Investment Trusts (REITs). For a period of 10 years, US Stocks mostly played second fiddle to their international counterparts. Even commodities showed a few strong years; something we haven’t seen much of coming out of the financial crisis.

When you take both periods and combine them, the results look like this:


If we were to take the chart back even further in time, we’d find the same thing - different asset classes performing and underperforming at different times with no useful pattern to inform us on how to successfully use this information to capture these moves. The stark reality is that one of the top performing asset classes in any given year is just as likely to fall to the worst in the next year as it is to repeat at the top.

The aim of diversification and asset allocation is to optimize return for a given level of risk over a full market cycle – recession, recovery, expansion, and contraction. You can see this in the consistency of the Asset Allocation (Asset Alloc.) portfolio in each of the charts above. It’s never at the top and never at the bottom.

An additional observation from these charts is worth mentioning. Traditionally, most investors have looked to bonds for protection against the downside risk of stocks, but stocks can also diversify the risk in bonds. Using the Year-to-Date numbers from the chart, we find high-quality bonds (Fixed Income) are negative 1.6% through September 30th while US Large Cap Stocks are positive 10.6%. Intuitively, a very conservative investor fears the volatility and uncertainty of stocks and may not want to include them in their allocation. However, this final chart from Morningstar reveals that over the period between 1970-2017 the minimum risk portfolio was actually a portfolio comprised of 33% stocks and 67% bonds2.


Yes, by adding stocks to a portfolio of bonds, portfolio risk was reduced and investment returns were increased over a 100% allocation to bonds. The essence of diversification is to own assets that zig and zag at different times.

Being prudent means a good investment advisor always has something to apologize for in any given year. Similar to a life jacket or a seat belt, diversification is only appreciated when the benefit is realized - over long periods of time and through normal swings in economic conditions. Diversification is not only about achieving optimal risk-adjusted portfolio performance, it’s also about minimizing regrets from investing in a way that doesn’t suit one’s tolerance for risk. It’s this mismatch that can lead to destructive behavior when times get tough.

Keep playing the long game in transportation safety and investing. You’ll be glad you did.

Happy Planning,

2. Stocks in this example are represented by the Standard & Poor’s 500®, which is an unmanaged group of securities and considered to be representative of the U.S. stock market in general and bonds by the 20-year U.S. government bond. Risk and return are based on annual data over the period 1970–2017 and are measured by standard deviation and arithmetic mean, respectively. Standard deviation measures the fluctuation of returns around the arithmetic average return of the investment. The higher the standard deviation, the greater the variability (and thus risk) of the investment returns. An investment cannot be made directly in an index. The data assumes reinvestment of all income and does not account for taxes or transaction costs.
