Glide Paths

Definition

A glide path is a *planned* change in your asset allocation over time. Instead of picking one stock/bond mix and holding it forever, you decide in advance how the mix will shift as you age — for example, "85% stocks at 45, 65% at 55, 50% at retirement." Like a plane descending toward a runway, the portfolio follows a pre-set trajectory rather than reacting to whatever the market does this year.

The most familiar glide path is the one inside a target-date fund. A "Target 2045" fund holds a stock-heavy mix today — often around 90% equities, via broad funds similar to VOO — and automatically slides toward bonds, in the spirit of BND, as 2045 approaches, typically landing near 40–50% stocks at the target date. The investor never places a trade; the schedule is the product.

Three points define any glide path:

• The starting mix — how aggressive the portfolio is early on, when the horizon is longest.
• The landing point — the allocation at (or after) the retirement date.
• The shape — how the mix travels between the two: a steady decline, a flat line, or, in the more interesting modern designs, a dip followed by a rise.

That third point is where the real debate lives. For decades "glide path" simply meant *equity goes down as you age*; newer research argues that around retirement itself, the opposite shape may handle risk better. Both are covered below.

Why It Matters

Your glide path decides how much risk you carry at each stage of life — and, crucially, how much you carry during the handful of years when risk does the most damage.

While you are young and accumulating, a heavy stock weighting makes sense: you have decades to recover from crashes, and a downturn means your contributions buy shares cheaply. As retirement nears, the calculus flips. The years just before and after you stop working are the window where sequence of returns risk peaks — a deep market drop then, combined with withdrawals, can permanently impair a portfolio even if markets later recover. A glide path is a pre-commitment device for that transition: you decide *now*, calmly, how risk will step down, instead of improvising during a crash or — just as common — never de-risking at all because stocks kept going up.

The classic declining path comes in two flavors worth knowing:

• A "to" glide path finishes de-risking *at* the retirement date and holds that final mix flat. It treats retirement day as the destination.
• A "through" glide path keeps gliding *past* the retirement date, trimming equities for another 10–20 years into retirement — treating retirement day as a waypoint, since you'll be drawing on the money for decades.

Neither is automatically better; "to" paths tend to be more conservative at the date itself, "through" paths hold more stocks longer to fight inflation over a long retirement. What matters is knowing which one your fund follows — two funds with the same year on the label can hold meaningfully different mixes at 65.

The Rising-Equity Glide Path (the Bond Tent)

Here is the modern wrinkle. Research by Wade Pfau and Michael Kitces, published in 2014, examined a counterintuitive design: the retiree starts retirement *more* conservative than usual — say 30–40% stocks — and then lets the equity share drift upward through the first decade or so of retirement, back toward 60–70%.

Plotted over a lifetime, equity exposure rises through the working years, dips into a valley around the retirement date, then climbs again. The bond allocation makes the opposite shape — a peak centered on retirement day — which is why the approach is often called a bond tent: a tent of bonds pitched over the most dangerous stretch of your financial life, taken down once the danger passes.

Why would *raising* stock exposure in retirement ever make sense? Because of how sequence risk is distributed. The scenarios that destroy retirements are almost all the same scenario: a severe crash in roughly the first five years of withdrawals, when the balance is largest and every withdrawal sells the most shares at the worst prices. The bond tent attacks exactly that window. Consider the two ways the early years can go:

• Markets fall early. You are holding your *lowest-ever* equity exposure precisely when the crash lands. The damage is muted, you spend from the bond side rather than selling depressed stocks, and the upward glide has you *buying* equities near the lows.
• Markets do well early. After several good years you are so far ahead of your withdrawal plan that the danger has largely passed — you have, in effect, already won. Rising equity from that stronger position adds growth and inflation protection for the later decades, when a crash can no longer ruin the plan.

In the Pfau–Kitces simulations, this shape matched or beat traditional declining paths in the worst-case retirements — the only ones that matter for failure risk — at the cost of somewhat lower *average* ending wealth, since you spend a decade holding fewer stocks. It is a trade: give up some upside in the good scenarios to blunt the bad ones. That is also its honest limitation — a retiree who never sees an early crash paid for insurance they didn't need. And because the path asks you to buy stocks *during* retirement, sometimes in scary markets, most implementations pair it with spending rules such as withdrawal guardrails to keep the plan followable.

An Income Investor's Glide Path

Dividend-focused investors often run a different kind of glide path — one defined less by the stock/bond ratio and more by *what the equity sleeve is for*. Through the accumulation years the portfolio emphasizes total return and dividend growth: broad market exposure plus compounding payout growers in the mold of SCHD. Approaching retirement, the mix gradually tilts toward holdings selected for current, dependable cash flow, so that by the time withdrawals begin, distributions cover a meaningful share of spending.

The key word is *gradually*. Converting a growth portfolio into an income portfolio in one move on retirement day concentrates all the transition risk — valuations, yields, and tax consequences — into a single moment. Sliding over five to ten years averages into income assets the same way dollar-cost averaging works on the way in, and gives the income stream time to prove itself before you depend on it (see portfolio income stability).

One more interaction worth noticing: a secured income floor reduces how much de-risking the glide path has to do. If reliable income — Social Security, a pension, an income floor built from bonds or annuities — already covers essential expenses, an early crash threatens comfort rather than solvency. A retiree with a strong floor may reasonably run a shallower tent, or none at all; one whose entire budget rides on the portfolio has far more reason to de-risk around the retirement date.

Example

Here is how equity exposure evolves across three stylized paths for someone retiring at 65. All figures are illustrative equity percentages — the remainder of each portfolio (100% minus the number shown) sits in bonds and cash. They show the *shapes*, not a recommended mix.

*(Illustrative only. Real target-date funds and advisor glide paths vary widely.)*

Read down each column and the philosophies emerge:

• The traditional declining path starts aggressive and never looks back — 85% at 45 sliding to 35% at 80, roughly the shape of a "through" target-date fund. Its 45–50% equity around 65–70 is moderate: lower than in youth, but still substantial when the danger window opens.
• The static 60/40 never glides at all. It is *more* conservative than the others in mid-career (60% vs 85% at 45) and *less* conservative than the bond tent at the retirement date (60% vs 35% at 65) — carrying the most equity of the three right when sequence risk peaks.
• The bond tent matches the traditional path in youth, dives to 35% at 65 — its most defensive posture lands exactly on the danger zone — and rebuilds to 65% by 80, when an early crash can no longer wreck the plan. At 80 it holds nearly *double* the traditional path's equity (65% vs 35%): less risk when a loss is fatal, more growth when it isn't.

All three can carry a similar *lifetime average* equity exposure while producing very different worst-case outcomes — the lesson of sequence risk is that *when* you hold your risk matters as much as how much. And no path executes itself: portfolios drift with markets, so the glide path only exists if periodic rebalancing pulls the mix back onto the line.

Common Mistakes

• Treating the glide path as autopilot for everything. A glide path is calendar-based, not valuation-based — it shifts your mix because you got older, not because stocks got cheap or expensive. That mechanical bluntness is a feature (no forecasting required) but also a limit: it is a schedule, not a market view.
• Assuming a target-date fund's path fits your situation. One-size-fits-all paths cannot see your pension, Social Security timing, or income floor. Two investors retiring the same year — one with a pension covering essentials, one funding everything from the portfolio — arguably need very different landing points, yet the fund gives them the identical mix.
• Not knowing whether your fund glides "to" or "through" retirement. The same target year can mean 50% stocks at the date and holding, or 55% still gliding down for 15 more years. Check the prospectus shape, not just the label.
• Choosing a shape and never rebalancing. Between the scheduled shifts, rebalancing does the real work — without it, a bull market quietly ratchets your equity share up and the drawn path exists only on paper.
• Cliff-edge de-risking. Converting the growth portfolio to the income (or bond) portfolio in one move on retirement day concentrates valuation and tax risk into a single date. Gliding over several years is the whole point.
• Copying the bond tent without accepting its cost. The rising-equity path gives up some expected wealth in good scenarios to protect the bad ones. If you would abandon it after three strong years of "missed" gains, the traditional path you can stick with is the better plan.

FAQ

What is a glide path in a target-date fund?

It is the fund's pre-programmed schedule for shifting from stocks toward bonds as the target year approaches — typically from roughly 90% equities decades out to near 40–50% at the target date. "To" funds stop adjusting at the target year; "through" funds keep reducing equity for a decade or two afterward. The glide path, not the individual holdings, is the main thing you are buying, so read the shape in the prospectus rather than relying on the year in the name.

What is a rising equity glide path?

A design, studied by Wade Pfau and Michael Kitces, in which a retiree *starts* retirement conservatively — often 30–40% stocks — and gradually increases equity exposure through the first decade or so of retirement, so lifetime equity exposure forms a valley centered on the retirement date. The logic: the retirements that fail are those hit by a crash in the first roughly five years of withdrawals, so that is when to hold the least equity; if markets instead do well early, the plan is safely ahead and can afford more stock later.

What is a bond tent?

The same strategy as a rising-equity glide path, described from the bond side: bond exposure is built up approaching retirement, peaks around the retirement date, then gradually shrinks during early retirement. Plotted over time, the bond allocation looks like a tent pitched over the most sequence-risk-vulnerable years — it is simply named for what the bonds do instead of what the stocks do.

Should retirees hold more bonds?

There is no universal answer — only considerations. Bonds reduce the damage a crash does exactly when sequence risk is highest, which argues for more of them around the retirement date. But a 30-year retirement also needs growth to outpace inflation, which argues against a bond-heavy mix forever — the insight behind letting equity drift back up later. Reliable outside income changes the math too: a retiree whose pension, Social Security, or income floor covers essentials can afford more equity risk than one funding every grocery bill from the portfolio.

Is a glide path the same as rebalancing?

No — they operate on different layers. The glide path changes the *target* allocation over time (65% stocks this year, 63% next year); rebalancing is the trading discipline that pulls the actual portfolio back to the current target after markets push it off. A glide path without rebalancing is just a drawing. Target-date funds do both for you, which is most of their value.

Do dividend investors need a glide path?

The concept still applies, but the axis often differs. Instead of only shifting stocks to bonds, an income investor typically glides the *purpose* of the equity sleeve — from total-return and dividend-growth holdings during accumulation toward current-income holdings approaching retirement — gradually, over five to ten years, rather than in one conversion on retirement day. A portfolio whose distributions already cover much of the owner's spending is also less dependent on selling shares in a downturn, which softens (though does not remove) the sequence-risk problem the glide path exists to manage.
