Risk Tolerance: How to Choose a Risk Level You Can Actually Hold

Your risk tolerance is the deepest fall your investments can suffer without you abandoning the plan. It is shaped by three things: when you need the money, how much loss you can stomach, and whether you draw an income from the portfolio. Before deciding which funds to hold, it pays to settle this question first, because it decides almost everything that follows.

The goal is not to pick the portfolio with the highest return on paper. It is to pick the highest level of risk you will genuinely stick with through the worst year.

Three questions that set your risk level

Three questions do most of the work:

• Horizon: when will you need this money? Money for a house deposit in three years and money for retirement in twenty-five years are different money. A short horizon leaves little time to recover from a deep fall.
• Tolerance: how deep a fall could you hold through? Not how deep a fall you would like to avoid, but how far your savings could drop before you would bail out.
• Income: will you withdraw from it regularly? Withdrawals make deep falls much more dangerous. When you take money out during a slump, you lock in losses and leave less capital to benefit from any recovery. This is known as sequence-of-returns risk.

What different mixes demanded in their worst moment

Numbers help make this concrete. The lesson compares three mixes in a backtested, hypothetical test from November 2004 to June 2026, using total return data for US stocks (SPY), long-term US Treasury bonds (TLT) and gold (GLD), rebalanced monthly, with no costs:

*Backtested, hypothetical, before costs. Past performance is not a guide to the future.*

The all-stock portfolio earned the most, but at its worst point $100,000 had shrunk to $45,000. The 60/40 mix bottomed at about $70,000, the mix with gold at about $75,000. Notice that both mixed portfolios earned the same 8.4% a year in this test, while the gold mix had a smaller worst fall.

The useful question is not which row looks best. It is which bottom you could live through without giving up.

The honest test for your risk tolerance: halve it

Here is a blunt check. Think of the worst fall you believe you could handle, then halve it.

If you instinctively said minus 40%, plan around minus 20%. That may feel overly cautious, but most people overestimate their tolerance when markets are calm. Ticking "−40%" on a questionnaire is easy. Watching your savings shrink for eighteen months, while every headline is gloomy, is something else entirely.

The real test of risk tolerance is a year of bad news, not a number on a form. Choose your risk level for the person you will be in a crisis, not the person you are on a quiet afternoon.

Defensive, balanced or growth

From these answers, most investors land in one of three broad levels:

• Defensive. A shorter horizon or regular withdrawals. Keeping falls small matters most, and a lower expected return is accepted in exchange.
• Balanced. A medium to long horizon. Moderate falls are acceptable; this is the middle of the road.
• Growth. A long horizon, no withdrawals, and the nerve to hold through deep falls in exchange for a higher expected return.

Growth carries a catch. It only works if the investor truly holds on. Someone who picks Growth and then exits in the first big fall would have done far better with Balanced: they take the deep loss but miss the recovery that was supposed to pay for it. A risk level is only as good as your ability to stay with it.

Your money is not one pot

Risk tolerance does not have to be one number for everything you own. Different goals can carry different risk levels:

• Emergency reserve: kept in cash.
• Money needed in the next 2–5 years: defensive.
• Long-term money: balanced or growth.

Matching each goal with its own risk level is often easier, both emotionally and financially, than forcing one compromise onto all your savings. A fall in the long-term pot is easier to sit through when you know next year's expenses are safely parked elsewhere.

What to do with this

• Write down your three answers: your horizon, the fall you could hold through, and whether you will withdraw regularly.
• Apply the halving test to your tolerance figure and use the halved number as your working limit.
• Look up the worst historical fall of the mix you have in mind and compare it with that limit, translating it into dollars on your own balance.
• Split your money by goal if your horizons differ: cash reserve, near-term money, long-term money.
• If the worst-fall number scares you, consider lowering the risk now, while markets are calm, rather than in the middle of the next downturn.
