Risk tolerance
Family III · Risk
Not to be confused with forex risk, correlation risk, gap risk.
Risk tolerance is the amount of uncertainty an investor can accept while pursuing a financial goal. It combines a psychological willingness to endure drawdowns with the practical capacity to do so, which depends on income, liabilities and time horizon. Because it is specific to the person or entity, two investors with identical portfolios may hold different risk tolerances.
Components and assessment
Risk tolerance is usually separated into two parts. Risk willingness is the emotional and behavioural side: how an investor reacts to a 20% decline. Risk capacity is the financial side: whether losses can be absorbed without derailing essential goals such as retirement or a house deposit. A high willingness with low capacity still produces a low overall tolerance.
Assessment methods vary by firm and jurisdiction. Common tools include questionnaires, scenario interviews and, less often, behavioural or capacity-based models. No single score is universal, and a tolerance recorded for one account or product may not apply to another.
Worked example
An investor has £250,000 in investable assets and needs £200,000 for a house deposit in three years. A 25% drawdown would reduce the portfolio to £187,500, below the required amount. Even if the investor states a high willingness to take risk, the capacity constraint limits the appropriate tolerance.
The 20% figure is the capacity limit. A portfolio whose worst expected drawdown exceeds 20% would breach the goal, regardless of the investor's stated willingness.
Use in portfolio construction
Risk tolerance informs the allocation between growth and defensive assets, the use of leverage, and the acceptable concentration in a single position. It is not a fixed number: capacity changes with age, income, debt and market conditions, so tolerance is typically reviewed periodically. Regulatory requirements for assessing and documenting risk tolerance differ by country and by firm.
Often confused with
- forex risk
- Forex risk is the exposure to currency movements affecting the value of positions or cash flows, whereas risk tolerance is the investor's willingness and capacity to bear loss; the visible sign is that forex risk is measured in currency pairs and exchange-rate changes, not in an investor's profile.
- correlation risk
- Correlation risk is the danger that assets assumed to move independently instead move together, reducing diversification, while risk tolerance is a personal or institutional limit on acceptable loss; the visible sign is that correlation risk is quantified with a correlation coefficient between assets, not with a questionnaire score.
- gap risk
- Gap risk is the possibility that a price jumps between trading sessions so that stops execute at worse levels than planned, whereas risk tolerance is the amount of loss an investor can accept; the visible sign is that gap risk appears as a discontinuity on a price chart, not as an allocation decision.
