Systematic Risk

Systematic risk refers to the risk inherent to the entire market or market segment. Systematic risk, also known as undiversifiable risk, volatility risk, or market risk, affects the overall market, not just a particular stock or industry. Systematic risk is both unpredictable and impossible to completely avoid. It cannot be mitigated through diversification, only through hedging or by using the correct asset allocation strategy.

Systematic risk underlies other investment risks, such as industry risk. For example, if an investor has placed too much emphasis on cybersecurity stocks, it is possible to diversify by investing in a range of stocks in other sectors, such as healthcare and infrastructure.

However, systematic risk incorporates interest rate changes, inflation, recessions, and wars, among other major changes. Shifts in these domains can affect the entire market and cannot be mitigated by changing positions within a portfolio of

public equities.

To help manage systematic risk, investors should ensure that their portfolios include a variety of asset classes, such as fixed income, cash, and real estate, each of which will react differently in the event of a major systemic change. An increase in interest rates, for example, will make some new-issue bonds more valuable, while causing some company stocks to decrease in price as investors perceive executive teams to be cutting back on spending. In the event of an interest rate rise, ensuring that a portfolio incorporates ample income-generating securities will mitigate the loss of value in some equities.

The opposite of systematic risk is unsystematic risk, which affects a very specific group of securities or an individual security. Unsystematic risk can be mitigated through diversification. While systematic risk can be thought of as the probability of a loss that is associated with the entire market or a segment thereof, unsystematic risk refers to the probability of a loss within a specific industry or security.

If you want to know how much systematic risk a particular security, fund, or portfolio has, you can look at its beta, which measures how volatile that investment is compared to the overall market. A beta of greater than one means the investment has more systematic risk (i.e., higher volatility) than the market, while less than one means less systematic risk (i.e., lower volatility) than the market. A beta equal to one means the investment carries the same systematic risk as the market.

The Great Recession also provides an example of systematic risk. Anyone who was invested in the market in 2008 saw the values of their investments change drastically from this economic event.
