Fish and Bones Investing

This week’s letter is about our portfolios and the return we earn for the risks we take. Flounder is tasty but be careful of the bones. January is a good time to review savings and assets and start making plans for 2024. Did I make any contributions to my IRA in 2023? After the gains in the stock market last year, how has my portfolio allocation changed? I thought I would take a wee bit of time to review the performance and key indicators of some model portfolios over the past sixteen years. We have endured a great recession, a financial panic, a slow recovery during the 2010s and a pandemic in 2020. Despite all those setbacks the SP500 index has more than tripled since December 2007. Huh?! Before I begin, I will remind readers that none of what I am about to say should be considered financial advice.

Allocation

A portfolio can be separated into three broad categories: stocks, bonds, and cash. Stocks are a purchase of equity or ownership in a company;  bonds are a purchase of public and private debt; cash is an insurance policy. Each of these can be subdivided further but I will stick with these broad categories. An allocation is a weighting of these types of assets. A benchmark allocation is 60/40, meaning 60% stocks and 40% bonds and cash. The percentage of stocks in a portfolio indicates an investor’s appetite or tolerance for risk. In this review I will discuss three allocations: 50/50, 60/40 and 70/30. A 70/30 allocation is considered more aggressive than a 50/50 allocation.

Investment Cohorts

The 50/50 portfolio was invested equally in the SP500 (SPY) and the total bond market (AGG) at the start of each 8-year period, beginning with the period that began in 2007. I will refer to these 8-year periods as cohorts, just like age cohorts. The 2007 cohort was “born” on January 1, 2007, and “died” on December 31, 2014. The second cohort was born on January 1, 2008, and died on December 31, 2015. There was no rebalancing done throughout each period to test the effect of a severe financial shock during the life of the investment.

Presidential Administrations

I picked an 8-year period because it aligns with two Presidential terms. A change in administration alters the political climate and presumably has some effect on a portfolio’s returns. The data, however, did not confirm that hypothesis. Presidential candidates try to persuade voters that their candidacy and their party will make people better off. To the millions of people trying to build a retirement nest egg, a change in administrations during the past 16 years had little effect. The market responds to forces much broader than the policies of any administration.

Specific Cohorts and their Returns

Let’s look at a few cohorts. Despite the severe downturn during 2007-2009, the slow recovery and the pandemic shock, the more aggressive 70/30 allocation delivered consistently higher returns than the two safer allocations. Obama’s two term Presidency began in 2009 at a decades low in the stock market, an opportune time to invest. However, that 8-year return had only the second highest return in this analysis. The highest return was the 2013-2020 cohort that consisted of Obama’s second term and Trump’s only term (so far).

Risk vs. Return

In 2008 a 50/50 portfolio cushioned the 37% loss in the U.S. stock market but over an 8-year period, the advantage of a safer allocation largely disappeared. In the period that began in 2008 all three portfolios delivered less than a 6% annualized return. During a severe downturn, a safer portfolio can mitigate an investor’s fears but the best tonic is a long term perspective. Generally the difference in returns is about 1% per year so the 50/50 portfolio earned 1% less than the 60/40 which earned less than the 70/30 portfolio. However the 70/30 investor absorbed more risk than the other two portfolios. In the chart below is the standard deviation (SD) of each portfolio, a measure of the risk or variation in a portfolio.

Performance Metrics

Recall that the 2013 cohort (green dotted line) had a return above 12%. The risk was almost 11%, a nearly one-to-one ratio of return to risk. Financial analysts have developed several measures of the tradeoff between risk and return. The Sharpe ratio is a measure of return that adjusts for risk by subtracting the return on a really safe investment from the return on the portfolio. The benchmark for a risk free investment is a short term Treasury bill (The interest rate on a money market account would be a close substitute).

Let’s use some rounded figures from the 2013 cohort as an example. The 70/30 portfolio earned 12% and a safe investment earned just 1%, a difference of 11%. That is the numerator in the Sharpe ratio. The denominator is the level of risk which is the standard deviation (SD) mentioned above. The SD was almost 11%, giving a ratio of 1. In the chart below is the Sharpe ratio for each cohort and shows that the actual ratio of 1.1 was close to the approximation above. Notice that the safer 50/50 portfolio often had the higher risk adjusted return.

From Peak to Valley

Investors may ask themselves “how much in return can I earn” when the more appropriate question is “how much risk can I tolerate?” The MDD, or maximum drawdown, is the greatest change in the value of a portfolio, regardless of the beginning and ending of a year. A portfolio might have gained 20% by October of 2007, then lost 60% in the next six months. The MDD would be 60%. It can be a gauge of your comfort level. Notice in the chart below that the MDD only varies under great stress like the financial crisis when the difference between the safer 50/50 allocation and the 70/30 portfolio was about 10%.

The Impact of Loss

We feel losses more than we do gains, even if the losses are only on paper. A portfolio that gains 20% only has to lose 16% to return to even. Regardless of our math abilities in a classroom, our instincts can be quite good at percentages. At higher gains, the percentages are painful. A portfolio that gains 50% then loses 50% nets a 25% net loss from our starting position (see notes at end). An MDD is a good indicator of “will this loss of value cause me to sell the investment?” In the early part of 2009 after the market had been battered, some clients could not handle the anxiety and sold some or all of their stocks, despite the advice from their advisors that this was the worst time to sell.

No Two Crises are Alike

Since December 2019, a few months before the pandemic restrictions began, the stock market gained 20% after adjusting for inflation (details at end). During and after the financial crisis, stocks lost 12% during the four years from December 2007 through December 2011 (details at end). The better response of asset prices during the pandemic era can be attributed to two phenomenon: technological advances and high government support of households and small business. During the financial crisis the majority of government support strengthened the foundations of financial institutions at the expense of households and small businesses. During the pandemic, many people could be productive from home. Students were in a virtual classroom with 15-30 other students. Had the pandemic happened in 2007, there was not enough bandwidth to support that kind of access, nor had the software been developed that could run that network capacity.

Takeaways

Households vary by income, by age, by health, circumstances and family characteristics. Each of these factors is a component of a risk exposure that a household faces. A younger couple might have time on their side but family obligations reduces their risk tolerance. Those obligations might include caring for an elderly parent or supporting a child’s educational goals. These models cannot replicate actual portfolios or individual circumstances but they do illustrate the smoothing effect of time even under the worst shocks. Risk tolerance is a matter of time tolerance.

A portfolio of $100 that gains 50% is then worth $150. If it loses 50%, the result is a value of $75, a net loss of $25 or 25%.

According to multpl.com, the inflation-adjusted value of the SP500 was 4708 in December 2023. This was a 20.6% gain above an index of 3902 in December 2019. The index stood at 2005 in December 2007, the first month of the Great Recession that would become the financial crisis in 2008. In December 2011, the index stood at 1762, an inflation-adjusted loss of 12%.

Price Plateaus

Occasionally the stock market plateaus for six to nine months. The competing market sentiments – positive and negative – that cause a price plateau usually turn in one direction or another. Rarely does this leveling period last for twelve months or more. When those indecisive conditions don’t resolve for a year, what happens next?

Let’s begin by looking at shorter duration plateaus which occur more frequently. The market gets a bit too exuberant or conflicting economic signals make it more difficult to predict the future. Some investors read the data and reach for risk; others read the same tea leaves and opt for safety.

In 1999, near the peak of the dot-com fever, prices plateaued for seven months before going onto new highs in 2000 . Again, the market paused for much of the year.  It was the end of the huge bull market of the 1990s.

In the beginning of 2004, investor indecision caused a leveling of price action after market sentiment had turned positive in 2003. The dot-com bust, the 2001 recession, the 9-11 tragedy, and the Enron and accounting scandals had combined to cut stock values in half by the spring of 2003. Investor optimism following the tax cut package of 2003 suffered when employment gains in late 2003 turned erratic. Investors were wary. Would this be a double-dip recession like the early 1980s? 

A relaxation of financial regulations helped spur more residential investment and the market continued upward. The erratic gains in employment were attributed to seasonal volatility in the construction industry. Many factors contributed to the complex international financial environment that spurred a boom in housing. In 2007, investors began to question market evaluations and prices plateaued for six months.

Two recent price stalls lasting more than twelve months seem to buck the trend of shorter-term plateaus. That there have been two in less than five years is concerning. In mid-2014, oil prices began a steep decline. Lower commodity input prices helped the profits of the broad market but by early 2015, investors grew worried that this decline was a reaction to a broad economic downturn. For 18 months, prices leveled. As voters went to the polls in early November 2016, prices were the same as in February 2015. Some voters chose an inexperienced Donald Trump as an alternative to Clinton 3.0 or Obama 3.0.

Shortly after the passage of tax reform in December 2017, investor optimism hit a peak and it has barely surpassed that high since then. The optimism of this year’s gains has only balanced the pessimism and losses of last year’s final quarter. What will happen after this? I don’t know. Investors need to think like fighters who stay balanced on their feet because they don’t know where the next punch is coming from.

Ten Year Review

To ward off any illusions that I am an investing genius, I keep a spreadsheet summarizing the investments and cash flows of all my accounts, including savings and checking. Each year I compare my ten year returns to a simple allocation model using the free tool at Portfolio Visualizer. Below is a screen capture showing the ten-year returns for various balanced allocations during the past several years.

10YrReturn20180112
The two asset baskets are the total U.S. stock market and the total U.S. bond market. A person could closely replicate these index results with two ETFs from Vanguard: VTI and BND. Note that there is no exposure to global stocks because Portfolio Visualizer does not offer a Total World Stock Asset choice in this free tool. An investor who had invested in a world stock index (Vanguard’s VT, for example) could have increased their annual return about 1.3% using the 60/40 stock/bond mix.

I include my cash accounts to get a realistic baseline for later in life when my income needs will require that I keep a more conservative asset allocation. An asset allocation that includes 10% cash looks like this.

In the trade-off between return and risk, a balanced portfolio including cash earns a bit less. In 2017, the twenty-year return was not that different from the ten-year return. From 2009 through 2011, ten-year returns were impacted by two severe downturns in the stock market.

The Hurt

Falling agricultural prices for seven years have put the hurt on many farmers. This decade may turn out to be as bad as the 1980s when many smaller farms went belly up because of declining prices. Remember the Farm Aid concerts?

The Bloomberg Agriculture Index has fallen about 40% over the past five years. While farmers get paid less for their produce, the companies who supply farmers with the tools and products to grow that produce are doing reasonably well. A comparison of two ETFs shows the divergence.

DBA is a basket of agricultural commodity contracts. It is down 33% over the past five years.
MOO is a basket of the stocks of leading agricultural suppliers. The five-year total return is 31%.

The large growers can afford to hedge falling prices. For family farmers, the decline in agricultural prices is a cut in pay. Imagine you were making $25 per hour at the beginning of 2017 and your employer started cutting your pay bit by bit as the year progressed? That’s what its like for many smaller farmers. They work just as hard and get paid less each year.

Stock Returns

Here’s an interesting table summarizing data from the Federal Reserve on comparative returns on stocks, T-bills and Treasury bonds from 1928 to 2008. What if you had put $100 a stock index like the Dow Jones in 1928? What would it be worth today?

What this illustrates is the power of compounding over a number of years. A nice gift from any parent or grandparent to a newborn child might be a small amount put in a stock index fund in trust for that child.
