Risk Tolerance vs. Risk Capacity

Risk tolerance and risk capacity are two distinct but related concepts that together should inform your investment strategy. Risk tolerance is subjective and psychological. It reflects how you feel about the possibility of losing money, how you react during market downturns, and how much volatility you can handle emotionally without making impulsive decisions like selling at the worst time.

Risk capacity, by contrast, is objective and financial. It is determined by factors such as your time horizon, income stability, savings rate, existing wealth, insurance coverage, and the flexibility of your financial goals. A young professional with a stable income, decades until retirement, and no dependents may have a high risk capacity because they have time to recover from market downturns. A retiree living on portfolio withdrawals with no pension may have lower risk capacity because market losses directly affect their ability to fund their lifestyle.

The challenge arises when risk tolerance and risk capacity diverge. A young investor with high risk capacity but low risk tolerance might invest too conservatively, potentially missing out on decades of growth. An older investor with low risk capacity but high risk tolerance might invest too aggressively, putting their retirement income at risk because they feel comfortable with volatility they can no longer afford to experience.

A thoughtful investment strategy considers both dimensions. Risk tolerance questionnaires, while imperfect, can provide a starting point for understanding your emotional relationship with risk. A comprehensive financial plan can assess your risk capacity by modeling different scenarios and showing how various portfolio allocations would perform under different market conditions.

Your risk tolerance and risk capacity may both change over time. Life events such as retirement, a health diagnosis, an inheritance, or a market crash can shift your emotional comfort level and your financial ability to bear risk. Regular review of your investment allocation in light of both factors may help ensure your portfolio remains appropriate as your circumstances evolve.
