As of mid-May 2026, the S&P 500 (via VOO) is sitting near $675, within two percent of its all-time high. The trailing one-year total return is roughly 25%. The Shiller CAPE ratio just printed 41, the second-highest reading in over 150 years of data, behind only December 1999. A lot of people who have been grinding toward a FIRE number for a decade are watching it cross the line not through patient compounding, but through six months of euphoric price action. If that is you, this article is for you. The dollar amount may be the same. The portfolio sitting underneath it is not.

Is it safe to retire when the stock market is at all-time highs?

Probably, but the margin of safety is meaningfully thinner than it would be at the same dollar amount after a flat decade. The dollar amount of your portfolio is the same number. The risk profile is not. A $2 million portfolio that just rallied 25% in twelve months is not the same financial object as a $2 million portfolio that has been grinding sideways for three years. The first one has farther to fall, and it has a much higher probability of falling.

That distinction matters because withdrawals do not care how you got there. The 4% rule, the Trinity Study, and every safe-withdrawal-rate framework built on US data assume you start drawing from a portfolio invested in a market with normal-ish valuations. They do not adjust for the starting CAPE. At a CAPE of 41, the historical record says forward 10-year real returns from this entry point have been low, flat, or negative. Drawing 4% a year from a portfolio that is returning 1% real is how plans fail.

What is sequence-of-returns risk, and why is it worst at a market top?

Sequence-of-returns risk is the risk that the order of your returns, not just the average, determines whether your retirement portfolio survives. Two retirees can average the same 7% real return over 30 years and end up in completely different places, because one of them ate a 40% drawdown in year one while withdrawing, and the other ate it in year 25 after their portfolio had compounded.

The damage is asymmetric. When you sell shares during a drawdown to fund living expenses, you sell more shares to get the same dollars. Those shares are gone. They cannot participate in the eventual recovery. A retiree who pulled $80,000 out of a portfolio that fell 50% in year one is permanently down on that $80,000 worth of shares, not just temporarily marked down. The first five to ten years of retirement contribute disproportionately to the 30-year outcome. Researchers like Wade Pfau and Karsten Jeske (Big ERN) have shown repeatedly that starting valuation is one of the strongest predictors of failure for a fixed withdrawal rate.

Retiring at a market top concentrates this risk. You are most likely to face an early drawdown precisely at the moment a drawdown does the most damage.

What does today's CAPE ratio of 41 actually mean for retirement?

The Shiller CAPE ratio (cyclically adjusted price-to-earnings, also called Shiller PE or PE10) divides the S&P 500 price by the average of the last ten years of inflation-adjusted earnings. It smooths out the cycle. Its historical median is around 16. Today it is 41. The only time in recorded US market history this was meaningfully higher was December 1999, right before a decade where the S&P 500 delivered a negative real return.

CAPE is a notoriously bad predictor of next year's return. Markets can stay expensive for a long time, and "expensive" is not a timing signal. What CAPE does do reasonably well is predict the forward ten-year real return. Higher starting CAPE has consistently meant lower forward returns. At CAPE 41, the historical record offers almost no examples of a strong subsequent decade.

Bill Bengen, the original author of the 4% rule, has been clear that his rule was derived from rolling historical periods that mostly started at much lower valuations. He has publicly suggested closer to 4.5% as a safer baseline in some regimes, and lower in others. The original 4% number is not a constant. It is a backtest result, and the regime matters.

Why does hitting your FIRE number in a melt-up feel different than it is?

Three psychological traps make this moment uniquely dangerous, and they all push in the same direction: pull the trigger.

Anchoring on the peak. Your brain locks onto the biggest number it has ever seen on your brokerage screen. If the portfolio drops 20% next year, you will feel like you lost something, even though that lower number is exactly what you would have celebrated retiring at eighteen months ago. This is not a rational response, but it is universal, and it leads people to make risk-management decisions (panic selling, going to cash at the bottom) that compound the original sequence-risk problem.

Recency bias. The phrase "the market always comes back" feels more true when it just did. After seven consecutive weeks of gains, the base rate that gets recalled is the recent base rate, not the long one. The long one includes 1929, 1966, 2000, and 2008. The long one includes 15-year real drawdowns. Those did not feel possible at the top either.

Finish-line fatigue. If you have been pursuing FIRE for a decade, the analytical case for waiting one more year gets steamrolled by the emotional case for being done. This is the most human and least helpful reason to lock in a withdrawal plan at peak valuations. The opportunity cost of one more year of work is small. The opportunity cost of a busted plan in year three of retirement is gigantic.

Has this happened before? (1929, 1966, 2000)

Yes, three times in modern US market history at comparable valuations. Retirees who pulled the trigger at the top in 1929 spent the next decade watching their portfolios destroy themselves under a 4% withdrawal. Retirees in 1966 (peak CAPE in the mid-20s, the start of a long real-return desert through the 1970s stagflation) had to make material plan changes to survive. Retirees in 2000 lived through a "lost decade" where the S&P 500 delivered negative real returns through 2010, and many of them were saved only by bond exposure and shrinking spending.

None of this is a prediction. The sample size is small and the next regime never matches the last one exactly. The point is more modest: this is not unprecedented. Plans that assume "the market always recovers in time" have failed before, and the people they failed had the same spreadsheets, the same charts, and the same gut feeling that their number was their number.

Should I delay retirement if the market looks overvalued?

Maybe, but that is the wrong way to frame the question. The right framing is: "what would have to be true for my plan to survive a bad sequence?" If the only answer is "the market keeps doing what it just did," your plan does not actually work. You are not retiring on a portfolio. You are retiring on a particular path the portfolio happened to take.

The honest version of this analysis usually produces one of three outcomes. Either your plan survives a 1966-style decade and you are fine to pull the trigger. Or your plan does not, and you need to change something: lower withdrawal rate, larger cash buffer, flexibility in spending, additional income, or yes, one more year. Or the plan is right on the edge, in which case "one more year" is cheap insurance for a problem that gets exponentially more expensive to fix once you have stopped earning.

What should I actually do if I hit my FIRE number at a market top?

Five concrete moves, in roughly the order they matter:

1. Stress-test with Monte Carlo and historical modes, not fixed returns. A 7% fixed-return projection is fiction. It tells you the average outcome of a distribution you do not live in. What you live in is one specific path. The FIRE calculator supports both Monte Carlo (random draws from a return distribution) and historical mode (every actual 30-year window since 1871). Run both. Look at the worst 10% of paths, not the median. If the bottom decile blows up your plan, you do not have a plan, you have a hope.
2. Build a two- to three-year cash and short-bond bridge. The technique is sometimes called a "bond tent" (Pfau / Kitces): temporarily over-allocate to bonds and cash around the retirement date, then glide back into equities over the first five to ten years. The point is not to time the market. The point is to never have to sell equities into a drawdown for living expenses. If the first three years are bad, you draw from cash. If they are fine, you rebalance and move on. The cost is some expected return. The benefit is removing the worst version of sequence risk.
3. Use a variable withdrawal rule instead of fixed 4%. Guyton-Klinger, the CAPE-based rule, or any rule that flexes spending down in bad years and up in good ones materially raises the safe withdrawal rate without changing the portfolio. Most people can absorb 10-15% spending cuts in a bad year without it ruining their life. Fixed-real withdrawals are the strictest possible rule, and they are why the 4% number is as conservative as it is.
4. Treat Barista FIRE, consulting, or one-more-year as insurance, not failure. A few thousand dollars a month of income in the first five years of retirement is worth absurd amounts of portfolio value, because it covers expenses without forcing sales during a drawdown. This is the cheapest insurance policy you will ever buy. If you are also still contributing to your 401k or HSA during those years, even better; see the 401k contribution guide and our side-income retirement strategies guide for the mechanics.
5. Stop anchoring on the peak number.If your plan only works at today's portfolio value, your plan does not work. A plan that requires the market not to mean-revert is not a plan, it is a bet. Decide on the number you would actually be comfortable retiring at if the market gave back the last twelve months of gains, because eventually it might. That is your real FIRE number. The current one is a screenshot.

Crossing the line at a melt-up isn't a victory lap. It is a gift you might have to give back. Treat the next twelve months like the start of an engineering problem, not the end of a savings goal.

Frequently asked questions

Is now a bad time to retire?

Not necessarily, but the historical record says that retiring near a CAPE peak has historically required either a flexible withdrawal rule, a cash buffer, or both. If your plan only works on a 7% fixed-return assumption from current valuations, the plan is fragile. Stress-test it before you commit.

What is a safe withdrawal rate when CAPE is high?

Most research from this regime (Pfau, Kitces, Big ERN) lands in the 3.0% to 3.5% range for a fixed-real withdrawal starting at CAPE readings above 30, versus the classic 4% number derived from a much cheaper historical average. Variable withdrawal rules (Guyton-Klinger, CAPE-based) can support a higher starting rate because they automatically flex spending down in bad years.

Should I move to bonds if I am close to retiring?

Some bond exposure in the first few years is the single best-studied defense against sequence-of-returns risk. Wade Pfau's "bond tent" approach gradually shifts toward bonds approaching retirement and then glides back into equities over the first decade. The goal is not to maximize return. It is to make sure you never have to sell equities during a drawdown.

Does the 4% rule still work in 2026?

The 4% rule was derived from rolling historical periods, most of which started at much lower valuations than today. Bill Bengen has publicly stated he considers it a starting point, not a constant. Most current research suggests starting closer to 3.0-3.5% if you insist on fixed-real withdrawals at today's CAPE, or using a flexible rule that can absorb bad years.

How much cash should I have before retiring?

A common rule of thumb is two to three years of essential expenses in cash, short-term Treasuries, or a short-duration bond ladder. That bucket gets you through the worst of an early drawdown without having to sell equities. Some practitioners go up to five years. More than that and you are over-insuring at the cost of long-term return.

Should I take profits and rebalance if my FIRE number was just hit?

Rebalancing back to your target allocation is mechanically the same as taking partial profits, and it is the version of "selling at the top" that does not require you to predict anything. If a 25% rally pushed your equity allocation well above target, rebalancing is the boring, correct answer. Selling everything because you "feel" toppy is market timing. Rebalancing is risk management.
