The Bond Tent and the Rising Equity Glide Path: Why Some Retirees Should Own More Stocks at 75 Than at 65

The Rule Everyone Learned Is Backwards for Retirees

For most of the last century, the standard advice about stocks and age fit in one sentence: hold your age in bonds. A 40-year-old should be 40% bonds, a 65-year-old 65% bonds, and an 80-year-old 80% bonds. Target-date funds encode a softer version of the same idea. The allocation slides steadily toward bonds until the investor stops working and keeps sliding afterward.

The logic seems airtight. Older people have less time to recover from a loss, so they should take less risk. But "less time to recover" turns out to describe the first few years of retirement, not the last ones. A crash at 66 hits a portfolio at its largest, just as withdrawals begin, and every dollar sold at the bottom is a dollar that is not there for the recovery. A crash at 82 hits a portfolio that has already done most of its work.

The bond tent and the rising equity glide path come from taking that asymmetry seriously. Instead of getting more conservative every year, the retiree is most conservative on the day they retire, and then becomes more aggressive over the following decade. This article explains the idea, replays it through 25 real years of market history, shows the retiree for whom it was a costly mistake, and covers the 2022 problem that every bond tent built since 2014 had to absorb.

What a Bond Tent Is

The name describes the shape of the bond allocation over time.

In the ten years or so before retirement, the bond share rises. A 55-year-old at 30% bonds might move to 60% bonds by 65. That half is conventional and matches what any target-date fund does. The unconventional half comes after the retirement date. Instead of continuing to add bonds, the retiree spends them down or rebalances away from them, and the bond share falls back toward 40% over the next ten to fifteen years.

Plot the bond percentage against age and it rises to a peak at retirement and falls away on both sides. That is the tent. The second half, viewed from the stock side, is the rising equity glide path.

The target-date column is an approximation; every fund family publishes its own path. The point is the direction. The classic rule and most target-date funds are still heading toward bonds at 75. The bond tent is heading back toward stocks.

Where the idea came from

The rising equity glide path was formalized by Wade Pfau and Michael Kitces in "Reducing Retirement Risk with a Rising Equity Glide Path," published in the Journal of Financial Planning in January 2014. Using both historical returns and Monte Carlo simulations, they found that portfolios starting retirement around 30% stocks and rising toward 60% generally failed less often, and fell shorter when they did fail, than portfolios that held a static allocation or followed a declining path. Kitces later coined "bond tent" to describe the full shape, including the build-up before retirement.

Their finding was not that stocks are safer for older people. It was that the timing of the exposure matters more than the average exposure. A retiree can hold the same average equity share over thirty years and get very different outcomes depending on whether that equity is concentrated early or late.

Why the First Decade Matters Most

This is sequence-of-returns risk, and the bond tent is aimed squarely at it.

Two retirees can earn exactly the same average return over 25 years and end up in very different places, because withdrawals turn the order of returns into a permanent effect. A 30% loss in year two, while the retiree is withdrawing 4% a year, has to be recovered from a smaller base with money still leaving. The same 30% loss in year twenty hits an account whose remaining job is much smaller.

Researchers often call the five years before and the five to ten years after the retirement date the retirement red zone. It is the window where the portfolio is at its largest in dollars, the retiree's ability to recover by working is gone, and withdrawals have just begun. The 4% rule is set by the worst sequences in history, and nearly all of them are bad because of what happened in this window.

The bond tent's argument follows directly. If the danger is concentrated in the red zone, the protection should be concentrated there too. Holding extra bonds for the full thirty years costs growth for the full thirty years. Holding them only through the red zone costs growth only while the risk is high.

A 25-Year Test: Retiring in January 2000

The right way to evaluate a strategy built for a bad first decade is to run it through one. The retiree who started in January 2000 faced the worst modern decade for stocks: three straight losing years, then 2008. Over 2000 through 2009, U.S. stocks averaged a 1.2% annual return and bonds 6.4%. Over the next fifteen years, 2010 through 2024, the roles flipped: stocks averaged 14.8% and bonds 2.5%.

That is close to the textbook case for a rising equity glide path, which is exactly why it is the right first test. It shows what the strategy is capable of when its premise comes true.

The replay uses published calendar-year total returns for the S&P 500 and the Bloomberg U.S. Aggregate Bond Index. The retiree starts with $1,000,000 and withdraws $40,000 in the first year, rising 3% a year for inflation. Withdrawals come out at the start of each year and the portfolio is rebalanced to its target allocation at the end of each year. Over 25 years the retiree withdraws $1,458,371, and the final year's withdrawal is $81,312.

Four allocations, identical spending, identical returns:

• Static 60/40. Sixty percent stocks every year.
• Static 40/60. Forty percent stocks every year.
• Rising glide path. Starts at 40% stocks and adds two percentage points a year, reaching 60% in the eleventh year and holding there.
• Declining glide path. The traditional direction. Starts at 60% stocks and drops two points a year to 40%.

Year-end balances

The rising glide path held 44% stocks at the end of 2002, 56% going into 2008, and reached 60% in 2010.

What the replay shows

The rising path protected the red zone almost as well as the conservative portfolio. By the end of 2002, after stocks had fallen 37.6% over three years, the rising glide path was at $871,368, against $757,975 for the 60/40. It ran just behind the static 40/60 through the 2008 crash and finished 2009 at $873,323, $131,176 ahead of the 60/40.

Then it had the stocks for the recovery. This is the half of the trade that the static 40/60 never made. By 2010 the glide path was at 60% stocks, the same as the 60/40, but sitting on a much larger base because it had not been cut down in 2000 through 2002. Every year of the 2010s bull market compounded that larger base. The static 40/60 stayed defensive the whole time. It pulled back ahead during the 2008 crash, when the glide path was already at 56% stocks, but the glide path passed it for good in 2013 and the gap widened every year after.

It beat both static portfolios by the end. The glide path finished at $1,284,052. That is $506,894 more than the static 60/40 and $425,448 more than the static 40/60. A plan that was more conservative than the 60/40 at the start and the same as it at the end won by half a million dollars, and the only thing that changed was when the stocks were held.

The traditional path did the worst. The declining glide path is what most retirees are told to do, and it finished at $485,845, $291,313 behind the plain 60/40. It held the most stocks in 2000 through 2002, when stocks were falling, and the fewest in the 2010s, when they were rising. It is the mirror image of the bond tent, and in this sequence it was the mirror image of its result.

The Retiree Who Paid for Insurance They Never Used

Run the same plan starting in January 2010, fifteen years through 2024. That retiree got one of the best opening decades in history. Stocks gained in every year from 2010 through 2017.

The glide path still finished comfortably, but it finished $285,783 behind the static 60/40. Every year it held fewer stocks than the 60/40 was a year it gave up part of a bull market, and in this sequence that was all of its first ten years. It did not protect the retiree from anything, because nothing happened.

That $285,783 is the premium on the insurance. It is real money, and the retiree who paid it is entitled to ask what they got for it. The honest answer is that they got the same thing a fire insurance policy gets a homeowner whose house does not burn down: protection against an outcome that, looking back, did not occur. Nobody knows in January which retiree they are going to be.

Four Retirement Dates Side by Side

Changing the start date is the best way to see what the strategy does and does not do. Each row uses the same $1,000,000, the same inflation-adjusted $40,000 withdrawal, and the same rules, running through the end of 2024.

The 2005 retiree hit 2008 in year four, inside the red zone. The glide path's low point was $40,809 higher than the 60/40's, and it finished slightly ahead. That is the more typical result when a single bear market lands early: a modest win at the end and, more importantly, a meaningfully higher floor in the worst year.

The 2021 retiree is a different story, and it is the one every bond tent built in the last decade had to live through.

2022: When the Tent Had No Floor

The bond tent assumes that when stocks fall, bonds hold up. For most of the last forty years that was a safe assumption. In 2000 through 2002, the aggregate bond index gained in every year that stocks lost. In 2008 it gained 5.24% while stocks lost 37%.

In 2022 it did not. Stocks lost 18.11% and the aggregate bond index lost 13.01%, its worst calendar year since the index began. Inflation had pushed interest rates sharply higher, and when rates rise, existing bond prices fall.

For a retiree two years into a rising glide path, holding 42% stocks, the portfolio lost about 15.2% in 2022. A static 60/40 lost about 16.1%. The bond-heavy allocation saved about one percentage point. The 2021 retiree on the glide path also had less stock exposure during 2021's 28.71% stock gain, so they entered 2022 with a smaller balance and hit a lower low than the 60/40 retiree did.

The lesson is not that the bond tent is broken. A one-year stock-and-bond decline remains rare. The lesson is that "40% stocks" describes the risk only if the other 60% is genuinely safe. A tent built from a long-duration aggregate bond fund is exposed to inflation and rate shocks in a way that a tent built from a short ladder is not, and the retiree should know which kind they own.

How to Build One

A rising equity glide path needs three decisions, written down before retirement.

1. The starting allocation. Pfau and Kitces's results favored starts around 30% stocks. Most practitioners use 30% to 50%. Lower starts protect more and cost more in a good sequence. A retiree with large guaranteed income from a pension or Social Security can start higher, because less of their spending depends on the portfolio.

2. The ending allocation and the speed. The replay climbs two points a year from 40% to 60%. Other common versions climb from 30% to 60% over fifteen years. The ramp should end once the red zone is behind the retiree, roughly ten to fifteen years in. There is no evidence that continuing to raise stocks indefinitely helps.

3. How the ramp actually happens. There are two ways, and the second is more practical.

• Rebalancing up. Each year, rebalance to a slightly higher stock target. Simple, but it means deliberately buying stocks every year, including after a crash.
• Spending the bonds. Take withdrawals from the bond side first. The stock share rises on its own as the bonds are spent, with no buying required. This is how most real bond tents are run, and it pairs naturally with a bond ladder where each rung is one year's spending.

Should the ramp pause in a down market?

Some advisors make the ramp conditional, and only shift toward stocks in years when stocks did not fall. That is a market-timing rule. In the 2000 replay it would have delayed the ramp through 2000 through 2002 and 2008, and the glide path would have entered the 2010s with fewer stocks. Mechanically continuing the ramp after a crash is what bought stocks at 2002 and 2009 prices. The rising glide path is at its most valuable precisely when it feels hardest to follow.

The Social Security Bridge Is a Bond Tent You Already Have

There is a version of the bond tent that many retirees build without knowing it.

A retiree who stops working at 65 and delays Social Security to 70 has to cover five years of spending from the portfolio before the larger benefit starts. Most planners fund that bridge from safe money: cash, short Treasuries, a CD ladder. During the bridge years, withdrawals are large and come entirely from the safe side.

Look at what that does to the allocation. On the first day of retirement, the bridge money makes the portfolio look conservative. Five years later, the bridge has been spent, the stock side has been left alone, and the portfolio's stock share is much higher. Then the delayed benefit starts, withdrawals drop sharply because Social Security is covering more of the spending, and the remaining portfolio has a long horizon. That is a bond tent. The retiree was most conservative at 65, became more aggressive by 70, and did it entirely by spending the right money first.

This is one reason Social Security delay and sequence-risk protection are usually discussed together. The delay raises guaranteed, inflation-indexed income for life, which shrinks the retirement income gap the portfolio has to fund, and the bridge that pays for the delay creates the rising glide path at the same time.

Bond Tent, Bucket Strategy, or Guardrails?

The bond tent is one of three common defenses against a bad sequence, and each one works on a different lever.

• The bond tent protects the allocation. It keeps equity exposure lowest in the years a crash does the most damage. It says nothing about which asset the withdrawals come from.
• The bucket strategy protects the withdrawals. It makes sure the next few years of spending are never sourced from a depressed asset. Run with a "spend the safe buckets first" rule, it also produces a rising equity share, which is why the two are often combined.
• Guardrails protect the spending. Withdrawal rules such as Guyton-Klinger cut spending when the portfolio falls and raise it when the portfolio grows, in exchange for an income that varies.

The 2000 replay used none of the bucket or guardrail mechanics, and the glide path alone still beat the 60/40 by about half a million dollars. In practice, a retiree can hold a bucket structure whose bond buckets are drawn down first, which produces the rising glide path, and set the annual withdrawal with a guardrail rule. In a Monte Carlo analysis, combinations generally outscore any single technique, because each covers a failure the others miss.

Common Mistakes With the Bond Tent

Confusing a bond tent with getting more conservative. The tent is temporary. A retiree who moves to 40% stocks at retirement and stays there has a conservative portfolio, not a bond tent. In the replay, the static 40/60 protected the red zone almost as well as the glide path and still finished $425,448 behind it, because it never bought back in.

Following the declining path out of habit. The traditional age-in-bonds direction ended last of the four portfolios in the 2000 replay. A 65-year-old retiree who becomes steadily more conservative is concentrating their equity exposure in exactly the years when a crash does the most harm and removing it in the years when it would help most.

Building the tent from long-duration bonds. The 2022 decline showed that an intermediate or long bond fund is not a reliable floor when inflation and rates rise. The red-zone assets should be short, laddered, or inflation-protected.

Ramping forever. The glide path should stop somewhere around 60% to 70% stocks once the first decade has passed. Raising equity exposure into the late eighties increases volatility in a portfolio that may be needed for long-term care and has fewer years left to recover.

Ignoring longevity. A 30% stock allocation held for 30 years is its own risk. It just shows up slowly. The bond tent works partly because it does not stay conservative, which matters for a retiree who might need the money to last into their nineties. See longevity risk in retirement for how long the planning horizon really is, and inflation risk for what a too-conservative portfolio loses over that horizon.

Abandoning the ramp after a crash. The ramp's best purchases happen after the worst years. A retiree who pauses the glide path in 2002 or 2009 because stocks just fell has turned an allocation strategy into a market-timing one.

Why This Matters for Advisors

The rising equity glide path is an easy idea to get wrong in a client meeting, because it sounds like advice to take more risk as the client gets older. Clients who absorbed "your age in bonds" decades ago will resist it, and a target-date fund statement showing the opposite direction does not help.

The framing that works is time-based rather than age-based. The first decade is the dangerous one. The plan starts conservative because that is when a crash would hurt most, and it rebuilds equity once that danger has passed. It is not a bet that stocks will do well later. It is a decision about when to hold the risk the plan already needs.

It also needs to be presented with its cost. The 2010 retiree paid $285,783 for protection they did not use, and the 2021 retiree found that the protection did little in 2022. An advisor who recommends a bond tent should show both the 2000 result and the 2010 result, explain what the bonds are and why they will hold up, and write down the ramp schedule. That turns the glide path from a theory into a documented, priced decision, which is what it should be in a compliance file.

How RetirementForge Helps

The Monte Carlo Analyzer runs a retirement plan through 10,000 return sequences at a stated stock allocation and reports when the failing paths fail. It holds the allocation constant, so it does not model the ramp itself. Running it at the starting allocation and again at the ending allocation shows what is at stake on each side of the tent, and the timing of the failures shows how much of the risk sits in the first decade. The Drawdown Planner schedules withdrawals from each account separately, so drawing from the safer accounts first, the mechanism that produces a rising equity share in practice, can be laid out year by year. The Social Security Break-Even tool shows what a delayed claim adds to lifetime income, and the Retirement Income Gap Analyzer sizes the bridge that delay requires.

Every assumption is documented and every client session is captured in an immutable audit trail, so the glide path agreed on before retirement is on the record when the first bear market arrives. Get started free and put the allocation schedule in front of a client with the numbers attached.
