What Is Tolerance Level?
Tolerance level, in finance, refers to an investor's emotional and psychological capacity to withstand fluctuations in the value of their investments. It represents the degree of discomfort or anxiety an individual is willing to experience as their portfolio's value declines, before potentially making irrational decisions. This concept is a core component of behavioral economics, recognizing that human emotions significantly influence financial decision-making, often leading to deviations from purely rational choices. Understanding one's tolerance level is crucial for effective financial planning and setting realistic investment objectives.
History and Origin
The understanding of how psychological factors influence financial decisions, including an investor's tolerance level, has evolved significantly. While traditional economic theory often assumed investors are rational actors, the emergence of behavioral economics challenged this view. Pioneering work by psychologists Daniel Kahneman and Amos Tversky in the late 20th century, particularly their development of prospect theory, laid much of the groundwork. Prospect theory demonstrated that individuals evaluate potential gains and losses differently, often exhibiting an asymmetric aversion to losses. Richard Thaler, a key figure in behavioral economics who won the Nobel Prize in Economic Sciences in 2017, further integrated psychological insights into economic analysis, showing how human traits systematically affect economic decisions and market outcomes.6, 7, 8, 9, 10 His work, alongside others, helped establish the recognition that an investor's emotional response to risk, or their tolerance level, is a vital consideration in financial theory and practice.
Key Takeaways
- Tolerance level quantifies an investor's psychological ability to handle investment losses and market volatility.
- It is a key factor in determining an appropriate asset allocation and overall investment strategy.
- A realistic understanding of one's tolerance level helps prevent impulsive decisions during market downturns.
- Misjudging tolerance level can lead to selling investments at a loss due to panic.
Interpreting the Tolerance Level
Interpreting one's tolerance level involves a self-assessment of emotional responses to potential financial losses. It's not about how much money an investor can afford to lose, but rather how much discomfort they are willing to endure. Investors with a high tolerance level may remain calm during periods of significant market volatility and view downturns as buying opportunities. Conversely, those with a low tolerance level may experience considerable stress and anxiety, potentially leading to decisions that undermine their long-term financial health, such as liquidating assets during a market correction. Financial advisors often use questionnaires to gauge this, assessing an individual's comfort with potential downside risk and market fluctuations.
Hypothetical Example
Consider two investors, Sarah and David, each with $100,000 invested.
-
Sarah (High Tolerance Level): Sarah invests primarily in growth-oriented equities. When the market experiences a 20% downturn, her portfolio value drops to $80,000. Sarah understands that market corrections are temporary and views this as part of the long-term investment journey. Her tolerance level allows her to stay calm, adhere to her investment horizon, and even consider buying more shares at lower prices, focusing on her growth investing strategy.
-
David (Low Tolerance Level): David has a lower tolerance level. When his $100,000 portfolio similarly drops to $80,000 during the same market downturn, he experiences significant panic and fear of further losses. Despite his initial long-term plan, his discomfort overrides his rational judgment. He decides to sell all his remaining investments to prevent more losses, locking in a $20,000 loss, effectively missing out on the subsequent market recovery.
This example highlights how different tolerance levels can lead to vastly different outcomes, especially during stressful market conditions.
Practical Applications
Understanding an individual's tolerance level is fundamental in various aspects of personal finance and investment management. Financial professionals use it extensively when developing a client's portfolio diversification strategy, ensuring that recommended investments align with the client's psychological comfort zone. For instance, regulatory bodies like the Financial Industry Regulatory Authority (FINRA) emphasize the importance of suitability, requiring investment professionals to consider a customer's investment profile, including their risk tolerance, when making recommendations.4, 5 This helps protect investors by ensuring they are not placed into products that are unsuitable for their comfort levels. During periods of market stress, such as the 2008 financial crisis, investor behavior, often influenced by their inherent tolerance level, played a significant role in market dynamics, with many reacting emotionally to widespread financial disruption.2, 3
Limitations and Criticisms
While essential, the assessment of tolerance level is not without its limitations. One common criticism is that an individual's self-assessed tolerance level can be highly subjective and may change with market conditions or personal circumstances. For example, an investor might report a high tolerance for risk during a bull market, only to find their actual emotional capacity much lower during a severe downturn. Questionnaires designed to measure tolerance level can also be flawed, as they rely on self-reporting and hypothetical scenarios that may not fully capture real-world emotional responses to financial loss.1 Some experts argue that focusing too heavily on "risk tolerance" can lead investors to misjudge their true capacity to bear losses, potentially setting them up for panic selling. The concept can sometimes conflate an investor's willingness to take risk with their actual ability to withstand losses, overlooking the objective reality of their capital preservation needs.
Tolerance Level vs. Risk Capacity
While often used interchangeably, tolerance level and risk capacity are distinct concepts crucial for comprehensive retirement planning.
- Tolerance Level refers to an investor's psychological willingness to take on risk. It is a subjective measure of comfort with potential investment losses and market volatility. It answers the question: "How much stress can I handle if my investments go down?"
- Risk Capacity, on the other hand, is an objective measure of an investor's financial ability to take on risk without jeopardizing their financial goals. It considers factors such as income, assets, liabilities, time horizon, and essential living expenses. It answers the question: "How much can I afford to lose without it negatively impacting my financial future?"
An individual might have a high tolerance level (psychologically comfortable with risk) but a low risk capacity (financially unable to absorb significant losses), or vice-versa. A sound investment strategy must align both.

An investor's tolerance level is influenced by several factors, including their personal experiences with money, personality traits (e.g., emotional intelligence), financial knowledge, and overall comfort with uncertainty. Market conditions can also temporarily affect perceived tolerance.
How is tolerance level typically assessed by financial advisors?
Financial advisors commonly assess tolerance level through detailed questionnaires that present hypothetical investment scenarios, ask about past reactions to market fluctuations, and inquire about an investor's comfort with various levels of investment risk. These assessments help tailor a suitable portfolio strategy.
Can an investor's tolerance level change over time?
Yes, an investor's tolerance level can evolve. Significant life events such as retirement, a change in financial status, or major market events can alter an individual's emotional readiness to accept risk. Regular reassessment with a financial advisor is advisable.
