What Is Non Market Risk?
Non market risk, also known as unsystematic risk or diversifiable risk, refers to the inherent uncertainty within a specific company, industry, or asset that is not related to broad market fluctuations. This type of risk is distinct from systematic risk, which impacts the entire market. In the context of portfolio theory, non market risk highlights factors unique to an individual investment that can be mitigated through proper diversification.
Unlike market-wide events such as recessions or changes in interest rates, non market risk arises from company-specific issues, like a product recall, a labor strike, or poor management decisions. While it cannot be entirely eliminated for a single asset, a well-constructed investment portfolio can significantly reduce its impact. Understanding non market risk is crucial for investors aiming to optimize their asset allocation and manage their overall portfolio risk effectively.
History and Origin
The concept of non market risk, often termed unsystematic risk, gained prominence with the development of Modern Portfolio Theory (MPT). Pioneered by economist Harry Markowitz in his seminal 1952 paper, "Portfolio Selection," MPT fundamentally changed how investors perceive and manage risk. Markowitz's work, for which he later received a Nobel Memorial Prize, emphasized that an investment's risk should not be assessed in isolation but rather by its contribution to a portfolio's overall risk and expected return.6
Markowitz demonstrated that combining assets with less than perfect correlation could reduce the total risk of a portfolio without necessarily sacrificing returns. This insight highlighted that certain risks, those specific to individual securities or industries (i.e., non market risk), could be "diversified away," while broader market risks could not. His paper laid the groundwork for modern portfolio management and the understanding of how to construct an efficient frontier of investments. The original paper, "Portfolio Selection," was published in The Journal of Finance.4, 5

- This type of risk can be significantly reduced, or even nearly eliminated, through portfolio diversification.
- Unlike systematic risk, non market risk is not compensated with higher expected returns in efficient markets.
- Understanding and managing non market risk is a cornerstone of Modern Portfolio Theory.
Interpreting Non Market Risk
Interpreting non market risk involves recognizing that not all risks in an investment portfolio are created equal. This type of risk is unique to a particular investment and does not affect the broader market. For instance, a pharmaceutical company faces the non market risk that one of its new drugs might fail clinical trials, or a retail chain might face business risk from a decline in popularity of its specific product line. These events would primarily impact the value of that company's stock, not necessarily the entire stock market.
The key insight is that because these risks are independent across different companies, holding a diverse array of investments can smooth out the impact of negative events affecting any single holding. If one company faces a setback due to non market risk, others in the portfolio might remain unaffected or even perform well, thus dampening the overall portfolio's volatility. Investors assess non market risk as part of their comprehensive risk analysis, factoring it into decisions about how much to diversify their holdings to align with their risk tolerance.
Hypothetical Example
Consider an investor, Sarah, who holds a portfolio consisting solely of stock in "Tech Innovations Inc." (TII). TII is a company that specializes in a single product: a new virtual reality headset.
Sarah's portfolio is heavily exposed to non market risk. If TII's new headset faces a manufacturing defect, or if a major competitor releases a superior product, the value of TII's stock could plummet. This is a specific operational risk and strategic risk unique to TII.
Now, imagine Sarah diversifies her portfolio. She sells half of her TII stock and invests in a well-established food production company, "Global Harvest Foods" (GHF), and a utility company, "Reliable Power Co." (RPC).
If TII's headset subsequently fails in the market, while her TII shares might still decline, the impact on her overall portfolio is lessened because GHF and RPC are unlikely to be affected by the same product-specific issue. GHF's value might be influenced by commodity prices or consumer trends, and RPC's by regulatory changes or infrastructure projects, but not by a virtual reality headset's sales. This example illustrates how diversification helps cushion the blow from non market risk.
Practical Applications
Non market risk is a critical consideration across various financial disciplines, influencing decisions from individual investing to institutional portfolio management. Its practical application primarily revolves around the principle of diversification to mitigate specific risks.
In individual investing, understanding non market risk encourages investors to avoid concentrating their holdings in a single company or industry. Instead, they spread their investments across different sectors, asset classes, and geographies to reduce the impact of an adverse event affecting one particular entity. This might involve investing in a mix of equities, fixed-income securities, and real estate, or holding shares in companies from various industries like technology, healthcare, and consumer goods.
For institutional investors and financial firms, managing non market risk is formalized through robust internal controls and risk management frameworks. For example, the U.S. Securities and Exchange Commission (SEC) has brought enforcement actions against firms for failures in internal policies and procedures designed to prevent misuse of information or address operational vulnerabilities. One such case involved an investment advisor that faced significant penalties and restitution due to "significant compliance failures" in managing proprietary investment models, underscoring the importance of addressing specific internal risks.3 Strong internal governance and oversight are essential to address these unique, company-specific vulnerabilities, including credit risk from counterparties or liquidity risk related to specific assets.
Limitations and Criticisms
While the concept of non market risk highlights the benefits of diversification, it is not without limitations and nuances. A primary criticism, particularly from the perspective of active management, is the ongoing debate about whether all "unsystematic" risks are truly uncompensated in the market. Some argue that certain company-specific risks might still offer a premium if they are not perfectly diversified away, or if investors are not fully rational in their diversification efforts. Discussions within investment communities, such as Bogleheads, sometimes delve into what constitutes "uncompensated risk" beyond the theoretical framework, questioning if an investor can ever truly eliminate all diversifiable risks or if some residual, unique risks might still be present in a concentrated portfolio.2
Furthermore, even with extensive diversification, non market risk can still manifest in unexpected ways. For example, a severe lapse in corporate governance or an unforeseen legal challenge specific to a widely held company could still cause significant, albeit localized, disruption. The recent scandal involving PwC Australia, where the firm faced a long-term ban from government work due to the misuse of confidential Treasury information, illustrates how internal control failures can lead to severe reputational and financial consequences, regardless of broader market conditions.1 While such an event is company-specific, its impact on stakeholders and even broader confidence in the consulting industry can be substantial. The effectiveness of diversification relies on the imperfect correlation between assets, but in extreme scenarios or highly concentrated portfolios, the impact of non market risk can still be significant.
Non Market Risk vs. Market Risk
Non market risk and market risk represent two distinct categories of investment risk, fundamentally differing in their scope and how they can be managed.
Feature | Non Market Risk (Unsystematic Risk) | Market Risk (Systematic Risk) |
---|---|---|
Scope | Specific to a particular company, industry, or asset. | Affects the entire market or a broad segment of it. |
Origin | Company-specific events (e.g., product recall, labor strike, management changes, legal issues). | Macroeconomic factors (e.g., inflation, interest rate changes, recessions, political events, pandemics). |
Diversifiable | Yes, can be significantly reduced or nearly eliminated through diversification across different assets and sectors. | No, cannot be eliminated through diversification; it is inherent to investing in the overall market. |
Compensation | Generally, no additional expected return for bearing this risk in efficient markets. | Investors are typically compensated with a risk premium for bearing this unavoidable risk. |
Other Names | Diversifiable risk, specific risk, idiosyncratic risk. | Non-diversifiable risk, beta risk. |
The primary point of confusion often arises because both types of risk can lead to investment losses. However, understanding their fundamental difference is crucial for effective portfolio management. Non market risk focuses on the unique vulnerabilities of individual investments, which can be mitigated by holding a diverse mix of assets. Market risk, conversely, is the pervasive risk of investing in the overall financial system, impacting all assets to some degree and requiring different strategies for management, such as hedging or adjusting overall portfolio beta.
FAQs
What are common examples of non market risk?
Common examples of non market risk include a company's executive team making poor strategic decisions, a specific product failing in the market, a lawsuit targeting a single company, a factory shutdown due to an accident, or a company defaulting on its debt obligations. These events primarily impact the individual company or a very narrow segment of the market.
Can non market risk be completely eliminated?
While non market risk cannot be entirely eliminated for any single investment, it can be significantly reduced, or effectively diversified away, at the portfolio level. By investing in a wide variety of assets that are not perfectly correlated, the negative impact of an adverse event on one asset is typically offset by the performance of others, minimizing the overall portfolio's exposure to this type of risk.
Is non market risk compensated with higher returns?
In an efficient market, investors are generally not compensated with higher expected return for bearing non market risk. This is because this type of risk is diversifiable; a rational investor can eliminate it through portfolio construction without needing extra compensation. Only systematic risk, which cannot be diversified away, is typically associated with a risk premium.
How does non market risk impact my investment strategy?
Understanding non market risk encourages a diversified investment approach. Instead of concentrating investments in a few individual stocks or sectors, an investor should spread their capital across a broad range of assets, industries, and geographies. This strategy helps to cushion the portfolio against the unique negative events that might affect any single holding, contributing to a more stable and potentially more consistent return profile over time.
