While there is no single “correct” allocation to equities in a retirement portfolio, it is clear there needs to be a material commitment.
There is no perfect asset allocation for a portfolio during the retirement years. Rather, there are several central questions to resolve. The primary question is how much of the portfolio should be committed to equities and how much to fixed income and cash.
While there is no precise rule or guideline about the “correct” equity allocation in a retirement portfolio, it is clear there needs to be a material allocation. I would suggest at least 40% or more for most retirees. Moving to a largely bond-based portfolio during retirement would be unwise in light of the likely upward movement of interest rates over the next period of time.
In this article, I highlight the performance of several Vanguard funds that might be considered for use in a retirement portfolio (Table 1). The funds are Vanguard Federal Money Market (VMFXX), Vanguard LifeStrategy Income
(VASIX), Vanguard Target Retirement Income
(VTINX) and Vanguard STAR
(VGSTX). Also included in this analysis is a custom group of Vanguard mutual funds and exchange-traded funds (ETFs) that I have assembled—seven Vanguard funds in all. I refer to this mix as the “7 Vanguard Funds for Life” model, which can be adapted to different life stages by changing the allocations among the seven funds. (Vanguard Federal Money Market represents an extremely conservative fund, but it is useful to have a 100% cash fund in the analysis for comparison purposes.)
TABLE 1. Vanguard Funds and Adjustable Portfolio of 7 Vanguard Funds
Vanguard LifeStrategy Income is a fund of funds that invests in five other Vanguard funds (shown below) with an overall allocation of approximately 20% stocks and 80% fixed income (as of January 2022):
Vanguard Target Retirement Income has an allocation of approximately 30% stocks and 70% fixed income that is achieved by investing in six underlying Vanguard funds. Allocations as of January 2022 were:
Vanguard STAR is a fund of funds that holds the following 10 actively managed Vanguard funds. It generally has an allocation that is approximately 60% stocks and 40% fixed income. As of January 2022, the allocations to each fund were:
The 7 Vanguard Fund Portfolio is a custom portfolio I have designed. In this analysis, I assigned different allocations to each of the seven funds resulting in two different portfolio models: a 40% equity/60% fixed-income portfolio and a 65% equity/35% fixed-income portfolio. The 65/35 mix is similar to the Vanguard STAR fund in terms of the equity/fixed-income allocation.
You can certainly build your own Vanguard-based retirement portfolio using the Vanguard funds you prefer (or a variety of ETFs and/or mutual funds from the investment company of your choice). For example, the underlying funds in Vanguard STAR can provide a starting point for a shopping list of Vanguard funds from which to build your own custom Vanguard portfolio. The advantage of building your own portfolio is that the funds you choose are held separately rather than comingled inside of a single ticker (as is the case with Vanguard LifeStrategy Income, Vanguard Target Retirement Income and Vanguard STAR). This means you have access to each fund individually when it comes time to withdraw money. You can pick and choose which fund to withdraw from based on each fund’s performance during the past quarter, year, etc. In short, you have multiple buckets from which to strategically withdraw money. In spite of well-designed “internal” diversification, a fund of funds does not give you that option.
Let’s now turn our attention to how each Vanguard fund and the two Vanguard portfolios fared during a 17-year period (2005–2021) in which money was withdrawn each year. The length of this analysis was dictated by two of the ETFs in the 7 Vanguard Fund model (their first full year of performance was 2005).
Each Vanguard fund (Vanguard Federal Money Market, Vanguard LifeStrategy Income, Vanguard Target Retirement Income and Vanguard STAR) along with the two Vanguard portfolios were allocated $1 million at the start of 2005. The first withdrawal at the end of 2005 was $50,000 (representing 5% of the starting balance of $1 million). Each subsequent end-of-year annual withdrawal was inflated by 3% (i.e., a 3% annual cost-of-living adjustment, or COLA). The total amount of money withdrawn by the end of 2021 (a 17-year period) was $1,088,079. The ending balances after 17 years of annual withdrawals are reported in Table 2.
TABLE 2. Ending Balances After COLA-Adjusted Annual Withdrawals
The multi-fund Vanguard portfolios were rebalanced annually to maintain the specific allocations assigned to each fund. Plus, the annual withdrawals from each fund in the two Vanguard portfolios were proportional to each fund’s assigned allocation. In other words, if a particular fund in the Vanguard portfolio was assigned an allocation of 10%, then 10% of the money withdrawn each year was taken from that fund, and so on.
Not surprisingly, the most conservative Vanguard fund in this analysis, Vanguard Federal Money Market, had the lowest ending balance of $86,943. Recall that more money was withdrawn than the starting balance, thus having a positive ending portfolio balance after 17 years of withdrawals is impressive for a 100% cash portfolio.
Vanguard LifeStrategy Income, with its roughly 20% equity allocation, fared considerably better. Its ending balance was nearly $600,000. Thus, it’s clear to see that having an equity allocation in a retirement portfolio is vitally important. If Vanguard Target Retirement Income was used as the retirement portfolio vehicle (with approximately 30% in equity) the ending balance after 17 years of withdrawals was just under $740,000.
The 40% equity/60% fixed income 7 Vanguard Fund Portfolio finished with $1.08 million—a remarkable achievement to have a balance after 17 years that was higher than the starting balance. And that’s after withdrawing over $1 million! Vanguard STAR produced an ending balance of $1.38 million with its target allocation of 60% equity/40% fixed income. Finally, the 7 Vanguard Fund Portfolio with a 65% equity/35% fixed-income mix produced an ending balance of just over $1.68 million.
Broad diversification across multiple funds (rather than a single-ticker fund of funds) is highly advisable during the retirement years. Let me say that another way—the most important time in your investing life cycle to be broadly diversified is during your retirement years. The notion is very straightforward: Retirees need multiple buckets from which money can be withdrawn. If the “buckets” represent funds that have low correlation to each other, it is unlikely they will all have a negative year at the same time.
Lastly, we evaluate how each Vanguard fund and the two Vanguard portfolios fared if money was withdrawn according to the required minimum distribution (RMD) schedule for a retiree between the ages of 72 and 88 (Table 3).
TABLE 3. Ending Balances After 17 Annual RMD Withdrawals
As before, each Vanguard fund along with the two Vanguard portfolios were allocated $1 million at the start of 2005. The first withdrawal at the end of 2005 was 3.65% (the RMD at age 72). The next RMD withdrawal was 3.77%. The third withdrawal was 3.92%, and so on through the RMD schedule.
Vanguard Federal Money Market had the lowest ending balance of $502,088 after having withdrawn a total of $690,941 over the 17-year period from 2005 through 2021. A retiree in an all-cash portfolio had more money remaining after 17 years (compared to the results in Table 2) but also withdrew substantially less money.
The RMD withdrawal each year is based on a percentage of the portfolio’s value at year-end; thus the annual withdrawal can actually decline year over year if the portfolio experienced a negative return for the year. In other words, if the portfolio balance declines, the percentage-based withdrawal will likely be smaller than in the previous year. A percentage-based withdrawal approach is what preserves a retirement portfolio. A forced withdrawal schedule (such as a retiree who demands a COLA each year) is a withdrawal method that can harm a retirement portfolio—even to the point of “early” depletion.
You will notice in Table 3 that the amount of money withdrawn varies across the different funds and two custom Vanguard portfolios. Once again, this is due to the fact that the RMD withdrawals are based upon the performance of the portfolio.
Vanguard LifeStrategy Income, with its roughly 20% equity allocation, had an ending balance of nearly $900,000 after having withdrawn a total of $895,440 over the 17-year period. A retiree using Vanguard Target Retirement Income finished with just over $1 million after having withdrawn $942,696.
The 40% equity/60% fixed income 7 Vanguard Fund Portfolio finished with $1.23 million after a total withdrawal of $1.052 million. Vanguard STAR had an ending balance of $1.53 million after total withdrawals of $1.11 million. Finally, the 7 Vanguard Fund Portfolio with a 65% equity/35% fixed-income mix produced an ending balance of just over $1.7 million and a total 17-year RMD withdrawal of $1.2 million.
What do we learn from all this? Retirement, for many, will likely be measured in decades, not just years. As such, many retirees are long-run investors who should maintain a material commitment to equity in their portfolios. Of course, it should be a diversified exposure to equity across multiple funds. At least a 40% equity allocation is likely appropriate for many retirees.
Individual circumstances will obviously impact a retiree’s specific asset allocation decision. When maintaining an equity exposure in a retirement portfolio we must commit to not being reactive to short-term market noise. If we allow ourselves to react to the day-to-day gyrations of the various equity markets around the globe, we will likely lose our nerve. Patience may be the hardest “asset class” to commit to during retirement, but will be the most important.
