The Bucket Approach to Building a Retirement Portfolio

Those who lived through the 1970s and ‘80s no doubt find their photographs from those decades to be cringe-worthy. But while few may wish to repeat a fashion era marked by pastel-colored suits and big hair, one aspect of those bygone decades is appealing—substantially higher interest rates than those that prevail today.

The average interest rate on a six-month certificate of deposit was 9.1% in 1970 and 13.4% in 1980. Of course, inflation was high then, too, but those higher rates, plus the prevalence of pensions, allowed many retirees to generate livable income streams without invading their principal or taking risks in stocks.

But two decades’ worth of declining interest rates dragged yields way down, dramatically compounding the challenge for retirees. With low yields on money market accounts and high-quality bonds, retirees’ choices were stark: To be able to afford retirement, they could plan to delay the date, save more, reduce their standards of living, or take more risks with their portfolios.

Yields have come up somewhat over the past few years, thank goodness. But the Bucket approach to retirement-portfolio management, pioneered by financial-planning guru Harold Evensky, aims to help retirees meet their cash flow needs regardless of prevailing interest rates. The Bucket concept is anchored on the basic premise that assets needed to fund near-term living expenses ought to remain in cash, dinky yields, and all. Assets that won’t be needed for several years or more can be parked in a diversified pool of long-term holdings, with the cash buffer providing the peace of mind to ride out periodic downturns in the long-term portfolio.

The All-Important Bucket 1

The linchpin of any Bucket framework is a highly liquid component to meet near-term living expenses for one year or more. Bucket 1 is by no means a return engine, but the goal of this portfolio sleeve is to stabilize the principal to meet income needs not covered by other income sources. To arrive at the amount of money to hold in Bucket 1, start by sketching out spending needs on an annual basis. Subtract from that amount any certain, nonportfolio sources of income such as Social Security or pension payments. The amount left over is the starting point for Bucket 1: That’s the amount of annual income Bucket 1 will need to supply.

More conservative investors will want to multiply that figure by two to determine their cash holdings. Alternatively, investors concerned about the opportunity cost of so much cash might consider building a two-part liquidity pool—one year of living expenses in true cash and one or more years of living expenses in a slightly higher-yielding alternative holding, such as a short-term bond fund. A retiree might also consider including an emergency fund within Bucket 1 to defray unanticipated expenses such as car repairs, additional healthcare costs, and so on.

Bucket 2 and Beyond

Although retirees may customize different frameworks for the number of buckets they hold and the types of assets in each, my Model Bucket Portfolios include two additional buckets, as follows.

Bucket 2: Under my framework, this portfolio segment contains five to eight years’ worth of living expenses, with a goal of income production and stability. Thus, it’s dominated by high-quality fixed-income exposure, though it might also include a small share of high-quality dividend-paying equities. Balanced or conservative- and moderate-allocation funds would also be appropriate in this part of the portfolio.

Income distributions from this portion of the portfolio can be used to refill Bucket 1 as those assets are depleted. Why not simply spend the income proceeds directly and skip Bucket 1 altogether? Because most retirees desire a reasonably consistent income stream to help meet their income needs. If yields are low, the retiree can maintain a consistent standard of living by looking to other portfolio sources, such as rebalancing proceeds from Buckets 2 and 3, to refill Bucket 1.

Bucket 3: The longest-term portion of the portfolio, Bucket 3 is dominated by stocks and more volatile bond types such as junk bonds. Because this portion of the portfolio is likely to deliver the best long-term performance, it will require periodic trimming to keep the total portfolio from becoming too equity-heavy. By the same token, this portion of the portfolio will also have much greater loss potential than Buckets 1 and 2. Those portfolio components are in place to prevent the investor from tapping Bucket 3 when it’s in a slump, which would otherwise turn paper losses into real ones.

Bucket Maintenance

The Bucket structure calls for adding assets back to Bucket 1 as the cash is spent down. Yet, investors can exercise a lot of leeway to determine the logistics of that necessary Bucket maintenance.

The following sequence will make sense in many situations:

1) Income from cash holdings in Bucket 1.

2) Income from bonds and dividend-paying stocks from Buckets 2 and possibly even 3. (Income-focused investors might decide that their bucket maintenance starts and stops with these distributions.)

3) Rebalancing proceeds from Buckets 2 and especially 3.

4) Principal withdrawals from the lowest-risk investments in Bucket 2, provided the above methods have been exhausted.
