What is Idiosyncratic Risk?

Idiosyncratic risk also known as unsystematic or specific risk refers to risk inherent to a particular company or industry. Unlike systematic risk which affects entire market, idiosyncratic risk is unique to a single company or small group of assets. It stems from factors such as company’s management decisions financial health or industry-specific events

For example consider two companies operating in technology sector. One company might experience significant decline in stock price. This is due to an internal scandal. The other might remain unaffected. This decline in the first company’s stock price is an example of idiosyncratic risk. It is specific to that company and does not impact the broader market.

Idiosyncratic Risk vs. Systematic Risk

To fully grasp the concept of idiosyncratic risk it’s essential to understand how it differs from systematic risk. Systematic risk also known as market risk refers to risk that affects the entire financial market or large segment of it. Factors like changes in interest rates, inflation. Recessions or political instability contribute to systematic risk.

Systematic risk cannot be eliminated through diversification because it impacts the entire market. For instance during the global financial crisis almost all assets across different sectors and geographies are likely to be affected. On the other hand idiosyncratic risk is specific to individual companies or industries. It can be mitigated by holding diversified portfolio.

Example of Idiosyncratic Risk

• Accounting Fraud: A company might engage in unethical accounting practices to inflate its earnings leading to scandal that causes its stock price to plummet. This risk is unique to the company involved in fraud. It does not affect the entire market.  
• Cyberattacks: If a company’s data security is breached it could suffer significant financial losses and reputational damage. Other companies in the same industry might also be vulnerable to cyberattacks. The impact on each company would vary based on their security measures and response strategies.  
• Loss of Key Personnel: The sudden departure of a CEO or other key executives can create uncertainty. It can negatively impact a company’s stock price. This risk is specific to the company. It can be mitigated by having a strong succession plan in place.  
• Product Recalls: A company that manufactures consumer goods might face an idiosyncratic risk if it has to recall a defective product. This event can lead to significant financial losses. It can damage company’s brand reputation
