Risk Averse: Definition, Examples & Investment Strategy
Understand risk aversion: Learn how risk-averse investors make decisions and build safer portfolios.
What Is Risk Averse?
Risk aversion is a fundamental concept in finance and investment management that describes the tendency of individuals to prefer outcomes with low uncertainty to those with high uncertainty, even when the average outcome of the higher-risk option is equal to or greater in monetary value. In simpler terms, a risk-averse person would rather have a guaranteed but smaller return than an uncertain but potentially larger return.
Someone who is risk averse has the characteristic or trait of preferring to avoid losses over making gains. This characteristic is typically associated with conservative investors or market participants who favor investments with lower returns and relatively known risks over investments with potentially higher returns but also with higher uncertainty and greater volatility. The concept is rooted in behavioral economics and helps explain why many investors choose stability and predictability over the possibility of higher profits that come with greater risk.
Understanding Risk Aversion in Finance
In economics and finance, risk aversion explains the inclination to agree to a situation with a lower average payoff that is more predictable rather than another situation with a less predictable payoff that is higher on average. For example, a risk-averse investor might choose to put their money into a bank account with a low but guaranteed interest rate, rather than into a stock that may have high expected returns but also involves a chance of losing value.
The concept of risk aversion is central to understanding investor behavior and portfolio construction. It acknowledges that investors are not purely rational actors seeking maximum returns; instead, they value certainty and are willing to sacrifice potential gains to reduce uncertainty. This preference for certainty has significant implications for how individuals allocate their capital across different asset classes and investment vehicles.
Risk Preferences: Three Categories
Economists and financial professionals classify individuals into three distinct categories based on their relationship with risk:
Risk Averse (or Risk Avoiding) — A person is considered risk averse if they would accept a certain payment of less than the expected value of a gamble, rather than taking the gamble and possibly receiving nothing. For instance, if presented with a bet where you have a 50% chance of winning $100 and a 50% chance of winning nothing (expected value of $50), a risk-averse person might accept a guaranteed $40 instead of taking the bet.
Risk Neutral — A person is risk neutral if they are indifferent between the bet and a certain payment equal to the expected value. In the example above, a risk-neutral person would be equally satisfied with either the gamble or a guaranteed $50 payment.
Risk Loving (or Risk Seeking) — A person is considered risk loving if they would accept a bet even when the guaranteed payment is more than the expected value. They would prefer the gamble over a guaranteed $60 payment in the example above, hoping to win the full $100.
The Certainty Equivalent and Risk Premium
Two important concepts help measure and understand risk aversion: the certainty equivalent and the risk premium. The certainty equivalent is the smallest guaranteed dollar amount that an individual would be indifferent to compared to an uncertain gain of a specific average predicted value. For risk-averse individuals, the certainty equivalent is smaller than the expected value of the uncertain gain.
The risk premium is the difference between the expected value and the certainty equivalent. It represents how much value a risk-averse person is willing to sacrifice to achieve certainty. For risk-averse individuals, the risk premium is positive, meaning they require compensation to take on additional risk. For risk-neutral persons, the risk premium is zero, and for risk-loving individuals, their risk premium is negative.
For example, if a risk-averse investor with a certainty equivalent of $40 faces a gamble with an expected value of $50, the risk premium is $10. This means the person would be willing to sacrifice as much as $10 in expected value to achieve perfect certainty about how much money will be received.
Measuring Risk Aversion: Mathematical Approaches
Economists have developed several mathematical measures to quantify risk aversion. One fundamental principle is that an agent is risk-averse if and only if their utility function is concave. A concave utility function reflects the concept that additional units of wealth provide diminishing satisfaction.
The Arrow-Pratt Measure of Absolute Risk Aversion (ARA)
The Arrow-Pratt measure of absolute risk aversion, named after economists Kenneth Arrow and John W. Pratt, provides a standardized way to measure risk aversion. This coefficient of absolute risk aversion accounts for the curvature of a person’s utility function. The higher the curvature of the utility function, the higher the risk aversion. However, because expected utility functions are not uniquely defined, economists use measures that remain constant across different mathematical representations of the same preferences.
The concept of Decreasing or Increasing Absolute Risk Aversion (DARA or IARA) describes how risk aversion changes as wealth increases. With DARA, individuals become less risk-averse as their wealth grows, which reflects the reality that wealthier individuals can often afford to take more risks. Conversely, IARA describes situations where risk aversion increases with wealth, though this is less commonly observed in practice.
The Arrow-Pratt Measure of Relative Risk Aversion (RRA)
The coefficient of relative risk aversion provides another important measure, focusing on how risk aversion changes proportionally with wealth. This measure is particularly useful for comparing risk aversion across individuals with different levels of wealth or for understanding how investment preferences should change as an individual’s financial situation evolves.
Risk Aversion in Portfolio Theory
In modern portfolio theory, risk aversion is measured as the additional expected reward an investor requires to accept additional risk. This concept is central to constructing optimal portfolios that balance return expectations with risk tolerance. If an investor is risk-averse, they will invest in multiple uncertain assets, but only when the predicted return on a portfolio that is uncertain is greater than the predicted return on one that is certain will the investor prefer the former.
The relationship between risk and return is a cornerstone of investment theory. Risk-averse investors demand a higher expected return to compensate them for taking on additional risk. The size of this compensation, known as the risk premium, varies depending on the nature of the risk and the investor’s specific risk aversion profile.
Investment Choices for Risk-Averse Investors
A risk-averse investor tends to avoid relatively higher risk investments such as stocks, options, and futures. Instead, they prefer to stick with investments that offer guaranteed returns and lower-to-no risk. Understanding which investments align with risk-averse preferences is crucial for building an appropriate portfolio.
Low-Risk Investment Options
Risk-averse investors typically gravitate toward several categories of investments known for their lower risk profiles:
Government Bonds and Treasury Bills — These are considered among the safest investments available, backed by the full faith and credit of the government. They offer guaranteed interest rates and have virtually no default risk.
Corporate Debt Instruments — Any type of debt instrument issued by a company, including corporate bonds, is generally considered a safe, low-risk investment compared to equity securities. These instruments are lower risk partly due to their characteristic of absolute priority. In the event of dissolution or bankruptcy of a company, there is a definite order of payback to the company’s creditors and investors. Legally, the company must first pay off debtors before paying off preferred shareholders and common shareholders.
Exchange-Traded Funds (ETFs) — While some ETFs come with higher risk, most ETFs, especially those invested in market indexes, are considered quite safe, particularly when compared to investments in individual stocks. They typically experience relatively lower volatility due to their diversified nature. However, it’s important to note that some ETFs are invested in significantly higher-risk securities, so careful selection is necessary.
Savings Accounts and Certificates of Deposit — These traditional banking products provide guaranteed returns and federal insurance protection (up to applicable limits), making them extremely low-risk options for conservative investors.
High-Risk Investments to Avoid
Risk-averse investors typically avoid the following types of investments:
– Individual stocks, particularly those of small or volatile companies- Options and derivatives, which can result in total loss of investment- Futures contracts with high leverage- Speculative or penny stocks- Cryptocurrency and other highly volatile digital assets- Emerging market investments with political or economic instability- Penny stocks and micro-cap companies
Constructing a Risk-Averse Portfolio
Building an appropriate portfolio for a risk-averse investor requires a strategic approach focused on capital preservation and steady, predictable returns. The typical allocation for a conservative investor might look significantly different from that of a risk-tolerant investor.
A conservative portfolio might include allocations such as 30-40% stocks (primarily large-cap, dividend-paying companies), 50-60% bonds and fixed-income securities, and 10-15% cash equivalents. However, the exact allocation depends on the individual’s specific circumstances, including age, income needs, time horizon, and personal risk tolerance.
Diversification is a key principle for risk-averse investors. By spreading investments across different asset classes and securities, investors reduce the impact of any single investment’s poor performance on their overall portfolio. This approach reduces unsystematic risk without necessarily sacrificing expected returns significantly.
Factors Influencing Risk Aversion
Several factors influence an individual’s level of risk aversion:
Age and Time Horizon — Younger investors with longer time horizons before retirement typically can afford to take more risk, while those closer to retirement often become more risk-averse as they focus on capital preservation.
Financial Situation — Individuals with strong financial positions and multiple income streams may be able to take more risk, while those with limited savings or dependents may prefer more conservative investments.
Experience and Knowledge — Investors with more experience and knowledge of financial markets may feel more comfortable taking calculated risks, while novice investors often prefer conservative approaches.
Past Experiences — Those who have experienced significant financial losses may become more risk-averse, while those who have benefited from taking risks might be more inclined to pursue riskier opportunities.
Personal Psychology — Individual temperament and emotional responses to market volatility play significant roles in determining risk aversion levels.
Frequently Asked Questions
What does it mean to be risk-averse?
Being risk-averse means preferring outcomes with certainty and lower returns over outcomes with higher uncertainty and potentially higher returns. Risk-averse individuals are willing to accept lower profits to reduce the possibility of experiencing losses.
How is risk aversion different from risk neutrality?
A risk-averse person prefers a guaranteed lower return to an uncertain higher return, while a risk-neutral person is indifferent between them. Someone who is risk-loving prefers uncertain higher returns even when a guaranteed lower return is offered.
Can risk aversion change over time?
Yes, risk aversion typically changes with life circumstances. As individuals age, accumulate more wealth, or experience significant financial events, their risk tolerance and aversion levels can shift. Generally, risk aversion tends to increase as people approach retirement.
What are the best investments for risk-averse investors?
Risk-averse investors should focus on government bonds, Treasury bills, corporate bonds, dividend-paying stocks of established companies, diversified ETFs, savings accounts, and certificates of deposit. These investments typically offer lower volatility and more predictable returns.
How do I know if I’m risk-averse?
If you prioritize capital preservation over maximum returns, feel uncomfortable with significant market fluctuations, prefer knowing exactly how much you’ll earn from an investment, or lose sleep over portfolio volatility, you likely have a risk-averse personality.
Is being risk-averse a bad investment strategy?
Not at all. Being risk-averse is a perfectly valid investment approach that aligns with many people’s financial goals and circumstances. However, extremely high risk aversion may result in returns that don’t keep pace with inflation over long periods.
