Key examples of unsystematic risk include management inefficiency, flawed business models, liquidity issues, or worker strikes. Systematic risk is not diversifiable i. Systematic risk affects much of the market and can include purchasing power or interest rate risk. Unsystematic risk—when it comes to investing in stocks—can be considered the unsystematic variance.
That is calculated by subtracting systematic variance from the total variance. Unsystematic risk is diversifiable, meaning that in investing if you buy shares of different companies across various industries you can reduce this risk.
Unsystematic risks are often tied to a specific company or industry and can be avoided. Systematic risk is a non-diversifiable risk or market risk. These factors are beyond the control of the business or investor, such as economic, political, or social factors. Meanwhile, microeconomic factors that affect companies are unsystematic risks.

Types of Unsystematic Risk. Unsystematic vs. Systematic Risk. Example of Unsystematic Risk. Unsystematic Risk FAQs. The Bottom Line. Key Takeaways Unsystematic risk, or company-specific risk, is a risk associated with a particular investment. Unsystematic risk can be mitigated through diversification, and so is also known as diversifiable risk.
Once diversified, investors are still subject to market-wide systematic risk. Total risk is unsystematic risk plus systematic risk. Article Sources. Investopedia requires writers to use primary sources to support their work. These include white papers, government data, original reporting, and interviews with industry experts. Unsystematic risk , also referred to as specific or idiosyncratic risk, is specific to a particular asset like a stock or property, or a similar group of assets such as technology or airline stocks.
The factors that contribute to each type of risk are different. For systematic risk, aspects like interest rate changes and recessions can cause entire markets to move. For unsystematic risk, the factors are more localised, like business failure of a specific company or industry e. While all investments are exposed to both types of risks on some level, diversification can help manage them to some extent.
The idea behind diversification is simple: by diversifying your investment portfolio, you are spreading your risks around.
Hence, a dip in a single security or asset class will not have as large a negative effect. The key to this is correlation — offsetting the risk of one type of asset against another. Correlation is the degree by which two securities move in tandem. For example, an index fund that tracks the Straits Time Index will be perfectly correlated with the index. A well-diversified portfolio thus consists of groups of assets which are lowly or negatively correlated with each other.
An investor holding a portfolio of 30 different technology stocks is not diversified at all. But an investor with a stock portfolio covering a range of industries, bonds and real estate, has a decent level of diversification. An empirical example relating diversification to risk reduction : In Elton and Gruber worked out an empirical example of the gains from diversification.
Their approach was to consider a population of 3, securities available for possible inclusion in a portfolio, and to consider the average risk over all possible randomly chosen n-asset portfolios with equal amounts held in each included asset, for various values of n.
Their results are summarized in the following table. Systematic risk is intrinsic to the market, and thusly diversification has no effect on its presence in investments. Recall that previously we talked about the security market line and the implication that investors require more compensation for extra risk.
One might pay the same amount for a safe investment as for an investment carrying more risk; however, the riskier investment will, in theory, provide a higher return. This is the principle behind the security market line. Diversification is a technique for reducing risk that relies on the lack of a tight positive relationship among the returns of various types of assets. By diversifying a portfolio of assets, an investor loses the chance to experience a return associated with having invested solely in a single asset with the highest return.
On the other hand, the investor also avoids experiencing a return associated with having invested solely in the asset with the lowest return — sometimes even becoming a negative return.
Thus, the role of diversification is to narrow the range of possible outcomes. As a result, the portion of risk that is unsystematic — or risk that can be diversified away — does not require additional compensation in terms of expected return. For example, consider the case of an individual who buys 50 corporate bonds from a single company. The individual receives a certain yield based on the purchase price.
However, if unexpected business risks lead to liquidity problems, the company might go bankrupt and default on its loans. In such a case, the investor will lose the entirety of the investment. Now, imagine that these 50 corporations are all given a lesser credit rating because of the risk of their overall market segment.
