When it comes to investing, all investors understand the reality of risk.
However, properly distinguishing between systematic and unsystematic risks enables more targeted risk management through diversification and hedging strategies.
In this post, we will clearly define these two core types of investment risk, provide illustrative examples of each, and outline specific methods to mitigate them in order to construct an optimally balanced portfolio aligned with one's financial goals and risk tolerance.**
Introduction to Investment Risks and Portfolio Strategy
Investors face two main types of risk when making investment decisions - systematic and unsystematic risk. Understanding the differences between these risks is key for developing an effective investment strategy and portfolio.
Understanding Systematic Risk in Security Analysis
Systematic risk refers to macroeconomic factors that impact the overall market. This includes:
- Interest rate risk - The risk that interest rate changes will affect asset prices. Rising rates typically hurt bond prices and the stock prices of rate-sensitive sectors.
- Inflation risk - The risk that inflation erodes the purchasing power of investment returns.
Systematic risks affect all businesses, asset classes, and securities to some degree through volatility and correlations. While systematic risk cannot be eliminated, investors can hedge using strategies like diversification, Treasuries, and TIPS.
Unsystematic Risk and Its Influence on Individual Securities
Unsystematic risk refers to factors specific to a company or industry that impact individual securities differently than the broader market. Examples include:
- Real estate investment trusts (REITs) dependent on regional property markets
- Companies with heavy R&D costs and uncertain product pipelines
Since unsystematic risks are unique to each company, they can be minimized through diversification. Well-diversified portfolios face little unsystematic risk.
The Role of Diversification in Risk Management
Diversification involves allocating investments across different assets, sectors, markets, and geographic regions to mitigate risks. By limiting exposure to any single investment, diversification aims to reduce unsystematic risk.
While diversification is effective for controlling unsystematic risk, it cannot safeguard a portfolio against systematic risk. Broad macroeconomic factors impact the overall market too strongly. Still, diversification remains a key risk management tool for investors.
Investment Decisions and the Balance of Risk Types
Most investment strategies balance both risk types using asset allocation - distributing a portfolio between stocks, bonds, real estate, cash, and other assets based on goals, time horizon, and risk tolerance.
Stocks face higher systematic and unsystematic risks but offer growth potential. Bonds carry systematic risk due to interest rate sensitivity but provide stable income. Cash minimizes risks with principal preservation but no growth.
By optimizing asset allocation, investors manage systematic risk through position sizing while minimizing unsystematic risk through diversification. Maintaining this balance of risks is key for long-term returns.
What is the difference between systematic and unsystematic risk?
The key differences between systematic risk and unsystematic risk in investing are:
Systematic Risk
- Affects the entire market and cannot be avoided through diversification
- Influenced by macroeconomic factors like recessions, wars, political events etc.
- Also called "market risk" or "undiversifiable risk"
- Examples include interest rate risk, inflation risk, currency risk
Unsystematic Risk
- Affects only specific assets or industries
- Caused by internal factors unique to a company or sector
- Can be reduced through diversification
- Also called "diversifiable risk" or "asset-specific risk"
- Examples include business cycle risk, financial risk, default risk
In summary, systematic risk impacts the entire market, while unsystematic risk is limited to specific stocks. Crucially, unsystematic risk can be minimized through diversification, whereas systematic risk cannot.
All investments carry some systematic risk. But investors can manage unsystematic risks by holding a diversified portfolio across various assets, sectors and geographies. This diversification allows investors to eliminate firm-specific risks.
Understanding both types of risk is key for asset allocation and risk management in investing. Diversification works well for unsystematic risk, while hedging instruments like options are better suited to protect against market downturns from systematic risks.
What is the difference between systematic risk and systemic risk?
Systematic risk and systemic risk are two important concepts in finance and investing that are often confused. However, there are some key differences:
Systematic risk refers to the risk inherent to the entire market or an entire asset class. Systematic risk affects all securities and cannot be avoided through diversification. Examples of systematic risk include:
- Interest rate risk - The risk that interest rate changes will affect asset prices and returns
- Inflation risk - The risk that inflation will undermine an investment's returns
- Recession risk - The risk of a broad economic decline that depresses asset prices
In contrast, systemic risk refers to the possibility that an event could trigger severe instability or collapse an entire financial system or market. Systemic risk examples include:
- Bank failure - If a major bank collapses, it could have ripple effects throughout the financial system
- Debt default - A major debt default by a country or large corporation could damage investor confidence and spur a broader financial crisis
The key difference is that systematic risk affects particular asset classes or securities while systemic risk poses a threat to the overall stability of financial systems.
Investors use tools like diversification to manage systematic risk in their portfolios. However, systemic risk is harder to predict and control. It often requires coordination between regulators, governments, and central banks to try to reduce systemic risk factors and prepare contingency plans.
So in summary:
- Systematic risk is market-wide risk inherent across an asset class
- Systemic risk can trigger instability or collapse across financial systems
- Diversification helps address systematic but not systemic risk
- Systemic risk requires a coordinated regulatory response to try to reduce likelihood of events that could cause financial system instability
Understanding these two concepts can help investors consider both macro market risks as well as risk reduction strategies at a portfolio level.
Is business risk systematic or unsystematic?
Systematic risk refers to market-wide uncertainties that affect all businesses, while unsystematic risk is industry or company-specific.
Systematic Risk
Systematic risk, also known as "market risk," impacts the overall market and cannot be avoided through diversification. Examples include:
- Interest rate risk - A rise in interest rates can slow economic growth and reduce stock prices.
- Inflation risk - Higher inflation can decrease consumer spending and business profits.
- Recession risk - An economic recession leads to reduced demand and lower revenues.
Companies have little control over these macroeconomic factors. However, they can hedge systematic risks by holding diversified portfolios or assets like gold and Treasury bonds.
Unsystematic Risk
Unsystematic risks are uncertainties unique to a specific company or industry, such as:
- Supply chain disruptions
- Lawsuits
- Poor management
- Competition
Investors can reduce unsystematic risk by holding a diversified portfolio instead of investing in individual stocks. While individual companies can take steps to minimize unsystematic risks through strong internal controls, these risks cannot be fully avoided.
In summary, systematic risk impacts the whole market while unsystematic risk is specific to a company or sector. Proper portfolio diversification is key to reducing exposure to unsystematic risks.
What is an example of systematic risk?
Systematic risk refers to the risk inherent in the entire market or market segment. It is the risk that cannot be avoided through diversification and affects the overall market, not just individual stocks or industries.
Some common examples of systematic risk include:
-
Interest rate risk: Changes in interest rates by central banks can affect stock and bond prices across all industries. For example, when interest rates rise, bond prices tend to fall across the whole market.
-
Inflation risk: Rising inflation typically causes the prices of goods and services to increase across many sectors of the economy. This reduces consumer purchasing power and can lead to lower revenues and profits for many companies.
-
Recession risk: An economic recession causes declines in incomes, employment, production, and spending across most industries and asset classes. Stock and bond prices often decline significantly during recessions.
-
Geopolitical risk: Major events like wars, terrorism, elections, etc. can create uncertainty across global markets and cause large market swings. For example, outbreaks of conflict can cause spikes in oil prices which affect most industries.
So in summary, systematic risk stems from macroeconomic and market-wide factors that affect the overall market. Investors typically cannot avoid systematic risk through diversification alone since it impacts most asset classes. Other risk management strategies like hedging and shifting allocation can help mitigate systematic risk exposure.

Systematic Risk vs Unsystematic Risk: Core Concepts and Examples
Systematic risk refers to the risk inherent in an entire market or asset class. This type of risk affects the overall market, not just individual investments. Examples of systematic risk include:
Systematic Risk Examples in Global Markets
-
Recessions - An economic recession leads to declining corporate profits, higher unemployment, and volatile stock prices across sectors. Investors' portfolios can face significant losses during recessions.
-
Interest rate volatility - Changes in interest rates set by central banks impact the rates at which companies and consumers borrow money. Sudden rate hikes can negatively impact investments across many asset classes.
-
Inflation risk - Rising inflation erodes purchasing power over time. This can prompt central banks to aggressively raise rates to curb inflation, leading to market-wide ripple effects.
Unsystematic Risk Scenarios in Individual Investments
Unsystematic risk refers to the risk specific to a company or industry sector. This type of risk can be minimized through diversification. Examples include:
-
Corporate scandal - Misconduct at an individual company, such as accounting fraud, can cause its stock price to plummet due to eroded trust. However, diversified portfolios limit the damage.
-
Supply chain disruption - A flood wiping out a supplier's manufacturing plant may significantly impact the stock price of affected companies. But it's usually an isolated event.
Difference Between Systematic and Unsystematic Risk
While systematic risk impacts the whole market, unsystematic risk only affects individual assets. For example:
-
Rising inflation (systematic risk) causes most equities and bonds to decline due to expected rate hikes.
-
A tech company's faulty product (unsystematic risk) causes its own stock to nosedive but has little effect on overall tech sector performance.
The key difference is that investors can minimize unsystematic risk via diversification across assets, sectors, and geographies. But systematic risk cannot be diversified away, since entire markets are moving in sync.
Quantifying Risk: Systematic and Unsystematic Risk Formulas
Calculating Systematic Risk: The Beta Factor
The beta coefficient is used to measure a stock or portfolio's systematic risk relative to the overall market. It quantifies how volatile an investment's returns are compared to the market benchmark. The formula is:
Beta = Covariance(Asset, Market) / Variance(Market)
- A beta of 1 means the asset moves in lockstep with the market
- A beta above 1 indicates greater volatility than the market
- A beta below 1 means less volatility
By analyzing beta, investors can determine if adding a stock will increase or decrease the systematic risk exposure in their portfolio based on how correlated it is with market moves.
Unsystematic Risk Formula and Its Applications
Unsystematic risk is unique to a specific asset and can be mitigated through diversification. It is measured by an asset's variance or standard deviation.
The formula is:
Unsystematic Risk = Standard Deviation(Asset)
A higher standard deviation means higher unsystematic risk. When constructing a portfolio, combining assets with returns that are not perfectly correlated can reduce overall unsystematic risk.
Interpreting Risk Measurements for Investment Strategy
By quantifying systematic and unsystematic risk, investors can make more informed asset allocation decisions:
- Prioritize assets with higher beta to gain exposure during bull markets
- Balance with low beta stocks and bonds to mitigate losses in bear markets
- Diversify across sectors, geographies to minimize idiosyncratic risk
- Hedge against systematic risk factors like interest rates using derivatives
Regularly monitoring and rebalancing the risk factors in a portfolio enables adapting to changing market conditions.
Diversification and Risk Reduction Techniques
Diversification is an effective strategy for managing unsystematic risk in an investment portfolio. By investing in a variety of assets across different sectors, geographies, and risk profiles, investors can minimize their exposure to company-specific or industry-specific risks. Some best practices for achieving diversification include:
Is Unsystematic Risk Diversifiable? Best Practices
- Invest across multiple asset classes like stocks, bonds, real estate, commodities, etc. This reduces reliance on equities.
- Within equities, invest globally across developed and emerging markets. This mitigates country-specific and regional risks.
- Own a broad mix of sectors like technology, healthcare, consumer staples, utilities, etc. This minimizes industry concentration.
- Construct a portfolio of at least 15-20 stocks. This decreases reliance on individual companies.
- Rebalance periodically to maintain target asset allocations over time.
Following these guidelines allows investors to effectively distribute unsystematic risks across a wide range of underlying assets. This makes the portfolio more resilient to isolated events.
Systematic Risk: Is Diversification Possible?
While diversification works well for unsystematic risk, it has little effect on systematic or market-wide risks like recessions and interest rate changes. Since these risks impact the broad market, most asset classes tend to move together when systematic risk events occur.
Rather than diversification, alternative risk management strategies should be used:
- Purchase defensive assets like treasury bonds, gold, and utility stocks that hold value during market downturns
- Invest in inflation-protected securities like TIPS (Treasury Inflation-Protected Securities) to hedge inflation risk
- Hold adequate cash reserves to meet spending needs during periods of volatility
- Work with a financial advisor to actively reallocate assets in response to changing market conditions
Asset Allocation to Manage Systematic Risk
Determining the right strategic asset allocation suitable to an investor’s risk appetite and investment timeframe is key to managing systematic risk. This establishes exposure limits to volatile assets like equities while providing some downside protection through fixed income.
Tactical asset allocation then involves periodically rebalancing between asset classes to maintain the target allocation. This forces investors to buy low and sell high - adding equities after market declines and trimming them after rallies to capture value.
Setting asset allocation ranges rather than fixed targets also provides flexibility to adjust allocations in response to signals about the market cycle. This can help mitigate systematic risk events.
Hedging Strategies Against Market Volatility
Sophisticated investors can also use hedging instruments to protect against market volatility stemming from systematic risk events like changes in interest rates. Common hedging strategies include:
- Derivatives - Futures, options, swaps to insure against or short market exposures
- Stop losses - Automatically sell if market decline passes a threshold
- Income investing - Focus on high dividend stocks and bonds to generate cashflow during volatility
Used judiciously, these techniques can mitigate the impact of systematic risk. However, hedging also comes with added costs and complexity. Retail investors may be better served by maintaining a balanced, diversified asset allocation aligned to their risk tolerance.
The Role of Financial Advisors in Risk Management
Financial advisors play a critical role in helping investors understand and manage risks in their investment portfolios. By evaluating an investor's financial situation and risk tolerance, advisors can provide tailored guidance on constructing a properly diversified portfolio, monitoring market conditions, and rebalancing assets as needed.
Assessing Risk Tolerance and Investment Goals
A key first step is for advisors to thoroughly assess each client's risk tolerance based on their investment timeline, income needs, and emotional ability to withstand market volatility. Advisors can then recommend appropriate asset allocations across stocks, bonds, cash, and other securities to align with an investor's financial goals and comfort with risk. More conservative investors may favor a higher allocation to fixed-income assets, while more aggressive investors may tolerate more equities exposure.
Portfolio Construction and Risk Mitigation
Drawing on modern portfolio theory, advisors construct portfolios that balance systematic market risk with unsystematic risk tied to individual securities. This is achieved through broad diversification across asset classes, geographies, sectors, and other categories. Advisors may also employ hedging strategies using options, futures, and alternative investments to mitigate downside risk. Portfolios can be structured to align with an investor's liquidity needs and risk preferences.
Monitoring and Rebalancing in Response to Risk Dynamics
Skilled advisors actively monitor portfolios and rebalance holdings as changes in asset valuations and risk exposures occur over time. This discipline is key to maintaining target allocations and optimal risk-return characteristics. Advisors can rebalance by trimming overweight asset classes and directing proceeds into underweight areas. Ongoing portfolio reviews also allow advisors to assess if the current construct remains appropriate for the investor's goals as their life situation evolves.
In summary, leveraging financial advisors' expertise in evaluating risk tolerance, constructing diversified portfolios, and providing ongoing risk management can prove invaluable for many investors seeking to achieve their long-term investment objectives.
Conclusion: Integrating Risk Considerations into a Cohesive Investment Strategy
Recap of Systematic vs Unsystematic Risk Dynamics
Systematic risk refers to market-wide uncertainties that affect all firms, such as recessions, wars, interest rate changes, and inflation. These cannot be avoided through diversification. Unsystematic risk refers to firm-specific uncertainties like lawsuits, strikes, defective products, etc. These can be minimized through diversification.
Key differences:
- Systematic risk impacts the overall market, while unsystematic risk only impacts individual assets.
- Systematic risk cannot be diversified away, while unsystematic risk can be reduced through diversification.
- Factors driving systematic risk include economic policies, political events, interest rates, etc. Firm-specific factors like management, lawsuits, supply chain issues drive unsystematic risk.
- Investors expect higher returns for taking on systematic risk exposure, while unsystematic risks provide no risk premium.
In summary, systematic risks arise from macroeconomic factors and affect the wider market, while unsystematic risks are unique to individual assets and can be managed through diversification.
Final Thoughts on Risk Management and Diversification
Effectively managing portfolio risk requires addressing both systematic and unsystematic risks. While systematic risk cannot be avoided, investors can hedge these risks through assets like gold, Treasuries, etc. Diversifying across unrelated assets, sectors, geographies, etc. remains key to minimizing exposure to unsystematic risks.
Constructing a resilient portfolio requires:
- Monitoring economic and market cycles to gauge systematic risk levels
- Diversifying across assets with low correlations to hedge unsystematic risks
- Rebalancing periodically to lock in gains and maintain target allocations
- Having stable assets like bonds to mitigate volatility from equities
- Considering alternative assets like commodities and real estate for further diversification
By integrating risk management practices that address both systematic and unsystematic risks, investors can build robust portfolios positioned to weather different market environments. The keys are assessing risk exposures, diversifying strategically, and rebalancing prudently.
