Company Specific Risk
What Is Company Specific Risk?
Company specific risk, also known as unsystematic risk or diversifiable risk, refers to the uncertainties inherent in a single asset or a small group of assets. This category of investment risk management focuses on factors unique to a particular company or industry, rather than broader market movements25. Unlike risks that affect the entire market, company specific risk can often be mitigated through strategic diversification within an investment portfolio.
History and Origin
The concept of company specific risk gained prominence with the advent of Modern Portfolio Theory (MPT), largely attributed to Harry Markowitz's seminal work "Portfolio Selection" in 1952. Markowitz, who later received the Nobel Memorial Prize in Economic Sciences in 1990 for his pioneering work, demonstrated mathematically how combining various assets could reduce overall portfolio risk, specifically by diversifying away unsystematic risks21, 22, 23, 24. Before MPT, investors primarily focused on the risk and return of individual securities in isolation. Markowitz's insights shifted the focus to how assets interact within a portfolio, highlighting that an asset's contribution to portfolio risk is not solely its individual volatility but also its correlation with other assets. This laid the foundation for understanding how diversification could reduce company specific risk.
Key Takeaways
- Company specific risk is unique to a particular company or industry.
- It is also known as unsystematic risk or diversifiable risk.
- This type of risk can be reduced or eliminated through proper diversification of an investment portfolio.20
- Examples include issues like a product recall, management changes, or a company-specific lawsuit.

Formula and Calculation
While there isn't a universally agreed-upon standalone formula for "company specific risk" as a direct, quantifiable value, it is often considered as the portion of an asset's total risk that is not explained by market risk. In financial modeling, particularly in the context of valuation, a "company-specific risk premium" (CSRP) is sometimes added to the discount rate to account for unique risks not captured by models like the Capital Asset Pricing Model (CAPM), which primarily accounts for systematic risk18, 19.
The total risk of an asset can be broadly decomposed into two components: systematic risk and unsystematic (company specific) risk.
The company-specific risk premium (CSRP) can be considered a subjective adjustment. However, some models attempt to quantify it, often as part of a "build-up method" for calculating the cost of equity. For example:
Here, "Total Beta" attempts to capture the total volatility of a standalone asset, while "Beta" specifically measures its systematic risk relative to the market.17
Interpreting the Company Specific Risk
Company specific risk is interpreted as the portion of an individual security's risk that is unique to the issuing company and can be mitigated by holding a sufficiently diverse range of assets. When evaluating a company, investors and analysts assess various internal and external factors that contribute to this risk. These include the quality of management, competitive landscape, product innovation, legal and regulatory challenges, and financial health16. A high level of company specific risk suggests that an investment's investment return could be significantly impacted by events unique to that company. Therefore, investors often conduct thorough due diligence and fundamental analysis to understand and evaluate these distinct risks before making investment decisions.
Hypothetical Example
Consider an investor, Sarah, who places all her investment capital into shares of a single fictional company, "TechInnovate Inc." TechInnovate Inc. is a small startup specializing in a single, unproven technology.
One morning, news breaks that a major competitor has developed a superior and cheaper alternative to TechInnovate Inc.'s core product. This news is devastating for TechInnovate Inc., causing its stock price to plummet by 50% in a single day. Since Sarah had all her capital in this one company, her entire equity securities holding experiences this significant loss.
This event illustrates company specific risk. The downfall was not due to a widespread economic downturn or a general decline in the technology sector (which would be market risk). Instead, it was caused by a factor unique to TechInnovate Inc. – a competitor's breakthrough. If Sarah had diversified her portfolio across multiple companies in different industries, the impact of TechInnovate Inc.'s decline on her overall wealth would have been significantly lessened.
Practical Applications
Company specific risk is a critical consideration in various financial practices:
- Portfolio Management: Professional fund managers and individual investors actively use asset allocation and diversification strategies to minimize exposure to company specific risk. By combining different assets whose unique risks are uncorrelated, the overall volatility of the portfolio can be reduced. For example, a portfolio holding shares in a technology company, a utility company, and a healthcare provider would likely have less company specific risk than one concentrated in just one of those sectors.
- Business Valuation: In valuing a private company or a specific project, financial analysts often incorporate a company-specific risk premium into the discount rate. This adjustment accounts for the unique operational, financial, or competitive risks that might not be captured by market-wide risk measures.
- Regulatory Filings: Publicly traded companies are required to disclose significant company specific risk factors in their annual reports, such as Form 10-K, filed with the U.S. Securities and Exchange Commission (SEC). 13, 14, 15These disclosures detail potential threats to the company's business, including legal challenges, reliance on key customers or suppliers, and management stability. Analyzing these factors is a key part of thorough investment analysis. For instance, the collapse of Enron in 2001, spurred by accounting fraud and internal mismanagement, stands as a stark example of how acute company specific risks, if undisclosed or poorly managed, can lead to catastrophic failure for a business and significant losses for its investors.
Limitations and Criticisms
While the concept of company specific risk is widely accepted, its precise quantification and complete elimination are not always straightforward. A primary criticism is the subjective nature of assigning a numerical value to company-specific risk premiums in valuation models. 12There is no single objective source for this data, often relying on the judgment and experience of the valuator.
Furthermore, while diversification is touted as the "only free lunch" in finance for mitigating company specific risk, there are practical limits to its effectiveness. 9, 10, 11True complete diversification across all possible company-specific factors is difficult to achieve, especially for individual investors with limited capital or who specialize in niche markets. Even a portfolio with a large number of holdings may still have some residual company specific risk if those holdings share underlying exposures or correlations not immediately apparent. Additionally, in extreme market downturns or "black swan" events, correlations between assets can increase, meaning that even well-diversified portfolios may still experience significant losses, blurring the line between systematic and company specific risk effects.
Company Specific Risk vs. Market Risk
Company specific risk, also known as unsystematic risk or idiosyncratic risk, refers to the uncertainties that are unique to a particular company or industry. These risks arise from factors such as a company's management decisions, product success, labor disputes, or specific regulatory changes impacting only that industry. 7, 8Importantly, company specific risk can generally be reduced or eliminated through proper diversification of an investment portfolio. For example, if an investor owns stock in ten different companies across various sectors, the negative impact of a product recall at one company is likely offset by stable or positive performance from the other nine, effectively minimizing the company-specific event's effect on the total portfolio.
In contrast, market risk, also called systematic risk, is the uncertainty associated with broad market movements that affect all investments to some degree. 6These factors are external to any single company and include economic recessions, changes in interest rates, inflation, political instability, or major global events. 5Market risk cannot be eliminated through diversification because it impacts the entire market simultaneously. Investors accept market risk as an inherent part of participating in financial markets and often seek compensation for bearing it through expected returns. The key distinction is that company specific risk is unique and diversifiable, while market risk is pervasive and non-diversifiable.
FAQs
How can investors manage company specific risk?
Investors manage company specific risk primarily through diversification. By investing in a variety of assets across different companies, industries, and geographic regions, investors can reduce the impact of any single adverse event affecting a specific company. 3, 4This strategy aims to ensure that the unique setbacks of one investment do not disproportionately affect the overall investment portfolio.
Is company specific risk the same as unsystematic risk?
Yes, company specific risk is synonymous with unsystematic risk. Both terms refer to the portion of an investment's total risk that is unique to a particular company or asset, rather than being driven by broader market factors. It is also sometimes called diversifiable risk because it can be mitigated through diversification.
Can company specific risk be completely eliminated?
While company specific risk can be significantly reduced through robust diversification, completely eliminating it in practice can be challenging. A perfectly diversified portfolio would theoretically have zero company specific risk, but achieving this requires investing across a vast number of uncorrelated assets, which may not always be practical or cost-effective for every investor. However, holding a reasonably diversified portfolio, typically consisting of 25-30 or more different securities, can remove most unsystematic risk.
What are common examples of company specific risk?
Common examples of company specific risk include a company experiencing a product recall, facing a significant lawsuit, undergoing a change in its senior management, suffering a major operational failure, or losing a key patent or contract. These events typically impact only the specific company involved, not the entire market.
Why is company specific risk important for valuation?
Company specific risk is important for business valuation because it reflects unique uncertainties that affect a company's future cash flows and profitability. 1, 2When valuing a private business or a specific project, financial analysts often add a "company-specific risk premium" to the discount rate. This adjustment accounts for the unique operational, financial, and competitive challenges specific to that business, providing a more accurate assessment of its intrinsic value.
