Why Index Funds and ETFs Are Good for Retirees

Christine Benz

Millennial investors were more likely than investors in other age groups to own exchange-traded funds, according to a survey from investment provider BlackRock.  Among investors age 21 to 35, 42% said they owned ETFs in 2017, up from 33% of investors in that same age group who said they had ETFs in their portfolios the year prior.

Given that ETFs are a new(er) investment innovation, it’s probably not surprising that the youngest investors would embrace them. What’s unexpected, however, is just how much ETFs have found a home in the portfolios of what BlackRock calls “Silver”-aged investors--people over age 70. Thirty-seven percent of investors within that age band said they owned an ETF in 2017, up from 22% a year earlier. That’s a higher uptake than among generation X investors, 29% of whom said they own ETFs, and baby boomers (27%). While older adults are often characterized as slow to adopt new products and services, that’s definitely not the case with ETFs.

Older adults’ embrace of ETFs may have something to do with the fact that, as retirement approaches, many investors look at their portfolios with a fresh set of eyes and make adjustments accordingly. A portfolio that was geared toward growth in all of those working years is now being tasked with a different job--providing cash flows for living expenses in retirement. That necessitates changes to the portfolio’s asset allocation, which may in turn prompt changes to the underlying investments in the portfolio.

Of course, active funds can work well in retiree portfolios, too, provided they’re of the very low-cost variety. My baseline model bucket portfolios--geared toward people who are retired--include both actively managed and index funds. Yet the more I work with in-retirement portfolios, the more I like ETFs and traditional index funds for the job, for the following reasons.

1) Index funds and ETFs lend themselves well to cash flow extraction. 
Retired investors can employ one of two key tacks to extract cash for living expenses from their portfolios: an income-centric approach or a total return/rebalancing approach (or a combination of the two). The good news is that index funds and ETFs lend themselves well to either.

For income-centric retirees, the small fees that index funds and ETFs typically levy ensure that more of their dividends flow through to shareholders. It’s all but impossible for more-expensive products with similar mandates to generate a competitive yield without taking on additional risk. (It’s not for nothing that my recent lists of Morningstar’s favorite high-dividend-yield and dividend-growth funds were heavy on the index products.) And while the original yield-focused index products often embedded hefty sector bets, and paid for it during the financial crisis when banks slashed their dividends, the best dividend-focused index products today control for those biases.

For total-return-oriented retirees who are using rebalancing (trimming appreciated securities) to meet living expenses, index funds and ETFs also work well. That’s because index funds and ETFs are typically pure plays on a given asset class. That makes it simple to identify which assets need to be scaled back to deliver the retiree’s desired cash flow and restore the portfolio to its desired asset-allocation mix. In late April 2019, for example, most index-fund investors who need cash from their portfolios will be able to extract it by selling appreciated U.S. equity holdings, and they’ll reduce risk in the process. 

2) Maintenance is a cinch. 
In addition to making it easy to extract cash flows, index funds and ETFs also stack up well in terms of limiting a retiree’s oversight obligations. That's an important consideration given that many retirees have better things to do with their time than monitoring the news flow related to their holdings. Yes, retirees employing index funds will need to keep tabs on their total portfolios’ asset-allocation mixes. But very little changes with most core-type index funds and ETFs on an ongoing basis. While a firm’s general indexing acumen is important, who’s actually managing an ETF or index fund is less important than is the case with actively managed funds. Index fund and ETF expense ratios are generally pretty stable, too; if anything, they’ve been trending down over the past decade. Finally, because index funds don’t make active bets, investors employing total market index products won’t find their total portfolios listing toward a single sector or part of the style box. Such investors will still need to oversee their overarching asset-class exposure, but they won't need to micromanage smaller-bore portfolio bets. 

3) It's not hard to control a portfolio's risk level with index funds and ETFs. 
Many retirees prize risk controls, and one comment I sometimes hear of active funds is that they’ll earn their keep in down markets. Indeed, to the extent that active funds have outperformed, it has tended to be in weak markets. Terrific active funds that have limited losses in tough times include  FPA Crescent (FPACX),  Vanguard Dividend Growth (VDIGX), and  Tweedy, Browne Value (TWEBX), to name just a random few. Yet there are also plenty of lower-risk index products that have managed downside volatility, including  Vanguard Dividend Appreciation ETF (VIG) and  SPDR S&P Dividend ETF (SDY). (Some of the low-volatility index products will also likely play good defense, though they weren’t around during the financial crisis.) 

Perhaps an even more important point is that even though mild-mannered funds can help lower a portfolio’s overall risk, the most dependable way to move the needle on a portfolio’s volatility level--and indeed its potential for real losses--is by adjusting the stock/bond mix, not the underlying holdings. 

4) The tax-efficiency stakes may be higher. 
Taxes are another area where the advantage accrues to index funds and ETFs in retirement. While bond index funds and ETFs have no special tax advantages relative to actively managed bond funds, equity index funds and especially ETFs are incredibly tax-efficient relative to their actively managed counterparts.

Of course, managing for tax efficiency is important at every life stage, but it's arguably most important in retirement. For one thing, investors' portfolios are often at their largest right before and during retirement; the share of the portfolio parked in taxable accounts is also apt to be highest at that life stage. Moreover, controlling taxable income in retirement doesn't just have the potential to lower your tax bill; it may also reduce the extent to which your Social Security income is taxed and reduce your susceptibility to Medicare premium surcharges that apply to high-income Medicare enrollees.   

5) A lower-return portfolio cries out for low-cost products. 
Finally, low-cost products make a ton of sense in retirement simply because holding more cash and bonds will tend to lower a portfolio's return potential; keeping expenses low helps ensure that a higher share of the returns flows through to the investor. Assume a retirement portfolio consists of a 10% cash position and 40% in bonds and 50% in stocks; if market return forecasts hold, that portfolio’s return won’t likely crack 5% over the next decade. If an investor pays 0.75% in asset-weighted expenses on such a portfolio, her return shrivels to 4.25%; she has ceded 15% of her gains. But if she’s able to limit expenses to 0.10% per year, her take-home return is 4.9% and she has surrendered just 2% of her return. As Vanguard founder Jack Bogle put it, you get what you don’t pay for, and not paying for investments is especially important when returns aren't especially high to begin with.
