Time Horizon and Risk Tolerance

Why this matters

The same investment can be sensible for one person and a poor fit for another. The difference is rarely the investment itself. It's how long the money can stay put, and how the person, and their finances, would handle a bad stretch.

Time horizon

Your time horizon is how long you expect to keep money invested before you need to use it.¹ It's usually tied to a goal:

The longer the horizon, the more time an investment has to recover from a bad year before the money is needed. That's why long horizons can usually handle more volatility. It isn't a guarantee: recoveries can take a long time, and some investments never recover. But a person who needs their money next year has no room to wait at all.

Risk tolerance and risk capacity

These two sound alike but measure different things.

• Risk tolerance is emotional: how large a drop you can live with without losing sleep or abandoning your plan.
• Risk capacity is financial: how much loss your situation can actually absorb, based on your time horizon, income, savings, and obligations.

	Leah	Omar
Age	28	58
Needs the money	At retirement, in about 35 years	At retirement, in about 4 years
Feels about market drops	Very anxious	Relaxed, enjoys the market
Risk capacity	High	Lower
Risk tolerance	Low	High

Leah's finances could handle large swings, but she might sell in a panic during one. Omar would stay calm during a drop, but with four years to go, a large loss could leave him short when he needs the money. Each has a mismatch, in opposite directions.

When tolerance and capacity disagree, the more cautious of the two usually deserves the most weight. A plan you'll abandon in a downturn doesn't work, and neither does a plan your finances can't survive.

Picture the drop before it happens

Risk tolerance is easy to overestimate when markets are calm. One way to test it: imagine a specific loss in dollars, not percentages.

If you had $50,000 invested and it fell 30%, you'd be looking at $35,000. That's $15,000 gone on paper, and nobody could tell you when it would come back. Would you hold on? Would you sell? Would you buy more? Your honest answer says more about your risk tolerance than any quiz.

One person, several horizons

Most people don't have a single time horizon. They have several goals, each with its own:

• An emergency fund, which could be needed tomorrow.
• A home deposit in three years.
• Retirement in thirty years.

It usually makes sense to think about each separately. Money for the home deposit shouldn't be exposed to the same risks as money for retirement just because it belongs to the same person.

Key takeaways

• Time horizon is how long money can stay invested. Longer horizons have more time to recover from drops.
• Risk tolerance is how much ups and downs you can live with. Risk capacity is how much loss your finances can absorb.
• When the two disagree, the more cautious one usually deserves the most weight.
• Different goals can have different horizons, and each can be treated separately.

Check your understanding

Omar, 58, plans to retire in four years and says he doesn't mind big swings. Which statement fits this lesson best?

1. Since his risk tolerance is high, he can take as much risk as he likes.
2. His age alone decides how much risk he should take.
3. His short time horizon limits his risk capacity, whatever his tolerance.

Dana has savings for a wedding in 18 months and a retirement account she won't touch for 30 years. How should she think about their time horizons?

1. Separately: the wedding money has a short horizon, the retirement money a long one.
2. Together: her time horizon is the average of the two, about 15 years.
3. By the shorter one only, so both pots of money should stay in cash for now.
