A key part of any investment plan is allocation. How you allocate will significantly affect your ability to reach your goals. It will also influence your ability to stick with a given strategy. Follow an allocation with too much volatility and you may abandon it during a market downturn. Favor investments less prone to bigger price swings and you may end up with too little growth to achieve your long-term goals.

This is why we started the project we’ve code-named “The AAII Way” by asking you to list your goals and assess your tolerance for risk. Without defining these two first, determining the right asset allocation is a guessing game. If you haven’t filled out the first two worksheets, I encourage you to do so. You can find them in the July and August 2020 issues of the AAII Journal or online at www.aaii.com/AAIIWay. [Update: This project became the PRISM Wealth-Building Process.]

Once you have stated your goals and defined your tolerance for risk, you can use them to identify an appropriate allocation strategy. The AAII Asset Allocation Models have long served as guidelines that individual investors can use to help construct appropriate portfolios. As part of The AAII Way, we are in the process of revising the moderate and conservative investor allocation models to improve the trade-off between risk and return.

AAII’s Aggressive Investor Model

The aggressive investor allocation model calls for a 90% allocation to stocks and a 10% allocation to cash; this model is staying unchanged. The suggested breakdown is 20% large-cap stocks, 20% mid-cap stocks, 20% small-cap stocks, 20% international stocks, 10% emerging market stocks and 10% intermediate bonds.

An alternative would be to use AAII founder James Cloonan’s Level3 approach or one or more of AAII’s model portfolios (Model Shadow Stock Portfolio, Dividend Investing, Stock Superstars Report and VMQ Stocks) for the stock portion. The bond portion is essentially a proxy for a low-volatility buffer. It could be substituted for cash-like assets to fund near-term goals and cash flow needs. Cloonan, for instance, suggested that retirees keep two to four years of planned withdrawals in cash or cash equivalents.

AAII’s Moderate Investor Model

The Moderate Investor Model is changing from a 70% diversified stock weighting to a 60% diversified stock weighting. The bond weighting is increasing from 30% to 40%. This change brings the moderate investor model’s equity/bond exposure in line with the well-established 60/40 allocation benchmark. The revised mixture is 20% domestic large-cap stocks, 15% domestic mid-cap stocks, 10% domestic small-cap stocks, 15% international stocks, 30% intermediate-term bonds and 10% short-term bonds. The bonds can be Treasuries, investment-grade corporate bonds or municipal bonds.

There are a few reasons for the change. The 60/40 allocation is a well-established benchmark. It has held up well against a variety of more complex allocation strategies. For retirees, the 60/40 allocation tends to work well with the long-established 4% withdrawal rule. Even at retirement periods of 40 years in length, portfolios using the simplified version of 60/40 did not run out of money 87% of the time. A variety of investment models and strategies center around the 60/40 approach.

The 60/40 allocation is also easier to follow. This is important because one of the reasons investors bail on their investment strategy is because the level of volatility is too high. While we can make the argument of volatility being the price of higher returns, psychological and financial tolerances vary. Not all investors can tolerate higher levels of volatility to realize higher returns. Just tweaking the equity and fixed-income weightings of AAII’s moderate investor allocation resulted in a better risk/return trade-off for many investors (a 20-year annualized return of 6.1% with a standard deviation of 10.1% versus a 6.6% annualized return and a standard deviation of 12.4%).

AAII’s Conservative Investor Model

The conservative investor model is also being made less volatile. It is currently 50% stocks/50% bonds. The mix is being lowered to 40% stocks/60% bonds. The new suggested weighting is 20% large-cap stocks, 10% mid-cap stocks, 10% international stocks, 40% intermediate-term Treasuries and 20% short-term Treasuries.

The small-cap stock exposure was removed to reduce volatility, large- and mid-cap international equity exposure was increased for diversification purposes and the exposure to short-term bonds was doubled. A basic 40/60 mix held up well for retirees following the 4% rule, with the portfolio lasting for a full 35-year period 86% of the time.

A 50-year test of allocation theory – AAII’s Changes to Asset Allocation Models There have been uncountable articles directing investors to allocate savings between equities and something safe. It has been going on for a long time. Few, if any of the articles, actually analyze what would happen if alternate strategies were to be used. Hindsight is 20/20. Using scientific methods we can test the past using a hypothesis and variations upon it. The following does just that. Disclaimer: one can’t predict the future but we have 50 years of modern times from which to learn. Is it true that with more the stocks, the results are better? Stocks don’t always go up and sometimes bonds do better. Yes. So maybe in those years the popular 60/40 split between equities and bonds would do better. Furthermore, when interest rates rise and can more likely thereafter fall to the benefit of bond holdings, perhaps one should own more of them. That’s readily analyzed if we look at what happens as rates fluctuate. Which rates? The Fed rate leads enough that it could be a good parameter. On the other hand changes in CPI could be even better as rates react to it. As rates rise, indicated by either the Fed rate or CPI, bond holdings could follow suit. These kinds of parameters and relationships should be tested, the more rigorously the better. Several scenarios need to be evaluated. Let’s use the Fed rate and CPI such that we are at the 60/40 split when rates are high. To do that let’s be in 40% bonds when the Fed or CPI “rate” hits a lofty 10%. That means the Fed rate multiplied by 4 would determine the percentage invested in bonds. The same goes for another evaluation using CPI. This way, most of the time the split is more heavily in equities but the bond percentage is opportunistically higher when bonds are paying more and likelihood for gains is greatest since rates will eventually drop from high levels and bond values will rise. Also, note that several times after inflationary rise, equities fall, so it should be good time to have a more balanced allocation. I gathered data from 1970 to today. That’s 50 years of data. For stocks, the S&P500 total return was used, including dividend reinvestment like I do in my retirement accounts. For bonds, I like the ‘High Yields’. After all, I’m investing to try to get ahead and the risk is not great. Average annual Fed rates and CPI indexes were used for two cases where the investment split was tied to current rates. Let’s compare the results. After the 50 years with 100% in HY bonds, a one-time investment of $1000 grew to $33,010. Thirty three times your money seems pretty good. Substituting stocks to the tune of a constant 60/40 split yielded a cool $127,210, so don’t even consider all bonds. What about the hypothesis that bond percentage tracking the Fed at 4 times the interest rate could be better? It was, delivering a whopping $165,130! This is starting to sound like I’m on to something. The same test using the CPI index was better yet, albeit not by much at $167,540. Over 167 times your investment was the best result but one must regularly change allocation with the changes in rates. If you feel you must have bonds to appease the pundits, your nerves, or your financial planner, this is the way to go! Wait again – what if all the age appropriate ‘financial correctness’ was ignored and one just left the $1000 in all equities? The total would be $257,660. Yes, that’s over 257 times your money. It’s time to draw your own conclusion. However, in retirement, there could be an untimely bad year on Wall Street when you need to take money (a RMD of $10,306 at 4% of that $257,660 for example) out of your account. Since the market has dropped two years in a row a couple times in 50 years, I would siphon off two years or 8% out of equities. That means you could carry a 92/8 split early in retirement. Logically, sell the portion of the 8% needed or required at a time when the stock market has dropped a lot. Replenish when equities rebound but keep in mind those rebounds after such travesties have been in the 30% range the following year so don’t be too hasty! Now I will not be ‘a la mode’ as I beg to differ with investment pundits. I see there could be better advice. Lemming thought is that as we age we should pare back investments in equities and replace them with bonds or worse, money funds. I’m old; old enough to be bucketed into “needing safe retirement practices”, at least to feel better. But I feel best when investments are actually doing better. If old age has to be the criterion for moving from stocks to bonds, I will declare I’m old if and when I hit 100. Maybe. In the meantime the advantage of holding nearly all stocks versus popular allocations is so great that it cannot be brushed aside – just keep a couple years of necessary funds out of equities.

Or something in between - we've been using 75/25 (+/-) for years. The wife's IRAs are at 76/24; my Roth is 60/30/10 (10 being precious metals; don't laugh - this year I'm beating her by 2%); the other accounts are whatever they need to be to keep the overall investment portfolio at about 74/26. We're both retired. We're comfortable being this aggressive, with a military pension and social security funding 100% of our budget.
