Your Risk Tolerance

Three kinds of risk

Risk tolerance is psychological. How much volatility can you live with without losing sleep, checking your balance constantly, or being tempted to sell at the wrong moment? This is about your temperament, not your finances.

Risk capacity is financial. How much volatility can you afford, given your time horizon, emergency reserves, and income stability? A 30-year-old with a stable job, six months of emergency fund, and no dependents has high risk capacity. A 60-year-old living off portfolio withdrawals has much lower capacity.

Risk need is goal-driven. How much volatility do you need to take on to hit your goals? Someone with a fully-funded plan doesn't need to take much risk; someone behind schedule may need to take more than they'd prefer.

A well-designed portfolio balances all three. Taking less risk than your capacity allows means leaving returns on the table. Taking more risk than your tolerance can handle means you'll panic-sell during a downturn and lock in losses.

The behavioral test

The practical test of risk tolerance is not how you feel in a rising market — it's how you felt in March 2020, or March 2009, or October 1987. If you sold during one of those periods, your real risk tolerance is lower than you thought. If you bought, it may be higher.

Investors who look at their portfolio daily tend to be less tolerant of a given level of risk than investors who look quarterly. The same portfolio looks much scarier if you check it every morning. One cheap way to increase your effective tolerance: stop looking at balances as often.

Common questionnaire items

Risk-assessment questionnaires typically ask variations on:

• If your portfolio dropped 30% in one year, what would you do? (Sell everything / sell some / hold / buy more)
• What return do you expect from your investments over the next 10 years? (Conservative / realistic / aggressive ranges)
• How long can your portfolio fund your expenses? (Emergency fund depth)
• How stable is your income? (Variability of cash flow)
• How soon will you need the money? (Time horizon)

There's no "right" answer — the goal is to surface your actual behavior patterns, not to steer you toward a particular allocation.

The portfolio you can stick with

A moderate portfolio you hold through a downturn beats an aggressive portfolio you panic-sell. This is the single most important thing to internalize about risk tolerance. The "theoretically optimal" allocation for someone with a 40-year horizon is probably 100% stocks — but very few people actually hold 100% stocks through a 40% drawdown. A 70/30 or 60/40 portfolio they will hold is empirically much better for them.

How tolerance changes over time

Risk tolerance usually decreases with age for three reasons:

• Time horizon shortens (capacity goes down).
• Accumulated wealth makes each percentage-point loss feel larger in dollar terms.
• Recovery time for any loss shrinks.

But it's not monotonic. Many retirees who enter retirement with a conservative portfolio become more risk-tolerant once they see their spending is well-covered by Social Security and a pension — they're investing "play money" and can afford to be aggressive.

How Horizons uses this

Your Risk Assessment score in Horizons maps to a recommended allocation strategy. That recommendation flows into your asset allocation schedule, which controls both the expected return and the volatility of your Monte Carlo simulations. If the recommended allocation is more aggressive than you're comfortable with, override it — the plan only works if you can actually hold it through a downturn.
