What Is Nonsystematic Risk and How Can You Manage It?

Investing involves navigating various uncertainties that can impact financial outcomes. Understanding the different types of risks associated with investments is a fundamental step for any investor. Being aware of these distinct risk categories allows individuals to make more informed decisions about their portfolios and anticipate potential challenges. This knowledge is crucial for effective investment management.

Understanding Nonsystematic Risk

Nonsystematic risk refers to uncertainties specific to a particular company, industry, or asset, rather than the entire market. It is often called “specific risk” because its impact is localized to a single investment or group. This risk stems from unique circumstances affecting only a subset of the market.

Another common term for nonsystematic risk is “diversifiable risk.” Investors can potentially reduce or even eliminate this risk through strategic portfolio construction. It arises from factors internal to a specific entity, such as management decisions, operational issues, or product-specific challenges. These factors do not typically influence the broader economic landscape or unrelated companies.

For instance, a sudden labor dispute impacting one company’s production line is a manifestation of nonsystematic risk. This event would primarily affect that specific company’s stock performance without impacting its competitors or the overall stock market. The localized nature of nonsystematic risk means its effects are confined, making it distinct from risks broadly affecting all investments.

Distinguishing from Systematic Risk

While nonsystematic risk is unique to specific investments, systematic risk, also known as “market risk,” affects the entire market. Unlike nonsystematic risk, systematic risk cannot be easily mitigated through diversification. It stems from broad economic, political, or social forces that influence all investments.

Factors contributing to systematic risk include widespread economic recessions, changes in central bank interest rates, or major geopolitical events. These events cause market-wide downturns that affect most companies and asset classes. For example, a significant rise in inflation could lead to higher borrowing costs across the economy, impacting the profitability of most businesses.

The core difference lies in their scope and origin. Nonsystematic risk originates from factors specific to an individual company or sector. In contrast, systematic risk arises from macroeconomic or global events, casting a wide net and influencing diverse investments. While investors can manage nonsystematic risk, they remain exposed to systematic risk as it is an inherent part of financial markets.

Examples of Nonsystematic Risk

Nonsystematic risk manifests from events unique to a specific company or industry. For instance, a technology company facing a sudden product recall due to a manufacturing defect would primarily impact its sales and stock price, not the broader market. The negative publicity and financial burden are specific to that company.

Another example is a pharmaceutical company failing to obtain regulatory approval for a new drug. The investment in research and development for that drug would be lost, negatively impacting future revenue projections. This setback is contained within the pharmaceutical firm.

A company could also experience nonsystematic risk if its key executive resigns unexpectedly. Similarly, a labor strike at a single manufacturing plant could halt production and reduce revenue. These examples illustrate how internal operational issues or specific corporate events create financial risk for an individual investment.

Managing Nonsystematic Risk

The primary strategy for managing nonsystematic risk is diversification. This involves spreading investments across various assets, industries, or geographic regions to reduce the impact of a negative event affecting any single investment. This approach aims to balance the portfolio so that gains from some investments can offset losses from others.

For example, an investor might diversify by holding stocks from different sectors, such as technology, healthcare, and consumer goods, rather than concentrating all holdings in one. They might also include different asset classes, such as bonds or real estate. The core principle is that events negatively impacting one company or industry are unlikely to simultaneously affect all others in a diversified portfolio.

While diversification is highly effective at reducing nonsystematic risk, it cannot eliminate systematic risk, which affects the entire market. Therefore, even a highly diversified portfolio will still be susceptible to broad economic downturns. However, for risks specific to individual companies or industries, diversification remains the most potent tool for investors.
