You can do everything right for 30 years—max out your 401(k), choose low-cost investments, and resist the urge to sell during panic—and still run out of money.
It sounds unfair, but the market does not care about fairness. It cares about timing.
Most investors obsess over their average annual return. They assume if the market averages 8% over the long haul, their retirement plan works. But when you switch from saving money to spending it, the average return becomes irrelevant. The only thing that matters is the sequence of those returns.
Financial planners call this “sequence of returns risk.” It is the single biggest threat to your financial longevity, and it strikes hardest during a specific, critical window: the five years before you retire and the five years immediately after.
The fragile decade
Think of your investing life as a mountain climb. The ascent is your accumulation phase. You are young, earning money, and buying shares. If the weather turns bad (a market crash), it actually helps you because you can buy shares at cheaper prices.
The summit is retirement day. The descent is your distribution phase. This is the “fragile decade.”
If you retire into a bear market, you face a mathematical disaster. You are no longer buying low; you are forced to sell low to pay your bills. When you sell depreciated assets to generate cash, you deplete your portfolio much faster than expected. You dig a hole so deep that even a massive bull market later may not pull you out.
Why average returns can be deceptive
Imagine two retirees, Sarah and Mike. Both start retirement with $1 million and withdraw 4%, or $40,000, a year (adjusted for inflation). Both experience an average market return of 6% over 20 years.
- Sarah enjoys a bull market immediately after retiring. Her portfolio grows early, creating a buffer that protects her from later crashes. She ends up leaving a massive inheritance.
- Mike retires the year the market drops 20%. He has to sell more shares just to get his $40,000. By the time the market recovers, he has too few shares left to benefit from the growth. He runs out of money in year 15.
They had the exact same savings at the start of retirement and the exact same average return during retirement. The only difference was the order in which the returns happened. This is why running out of money is the No. 1 fear for retirees.
The problem with reverse dollar-cost averaging
During your working years, you likely benefited from dollar-cost averaging by investing the same amount of money every month. When prices were down, your dollars bought more shares.
In retirement, the math flips. You are now doing “reverse dollar-cost averaging.” You withdraw the same amount of cash every month to live on. When share prices are down, you must sell more shares to get that cash.
This permanently locks in your losses. Once a share is sold, it is gone. It cannot grow when the market inevitably recovers.
How to build a shield
You cannot predict what the market will do the year you hand in your retirement notice. You can, however, structure your assets to survive a bad sequence.
1. Create a cash buffer
Keep one to two years of living expenses in cash or cash equivalents (like money market funds or high-yield savings). If the market crashes the year you retire, do not sell stocks. Spend your cash buffer instead. This buys your portfolio time to recover before you have to sell anything.

2. The bond tent
Many advisors recommend increasing your allocation to bonds in the five years leading up to retirement — meaning increase the percentage of your total savings that’s invested in bonds — and then slowly decreasing it again later. This reduces volatility right when your portfolio is most vulnerable, as bonds are less volatile than stocks.
3. Be flexible with spending
The 4% rule assumes you increase your withdrawals by inflation every single year, regardless of market performance. That is dangerous. If the market takes a hit, skip the inflation adjustment or cut discretionary spending (like travel) for a year.
A small belt-tightening early on can save the portfolio for decades. Even slight adjustments can lower the magic number you need to survive.
Survival of the flexible
The transition from a paycheck to a portfolio is not just a psychological shift; it is a mathematical one. The strategies that built your wealth are not the same ones that will preserve it.
Focus less on chasing the highest possible return and more on reducing volatility during this critical 10-year window. If you can survive the fragile decade with your principal intact, the odds of your money lasting as long as you do skyrocket.
