Systematic risk
VULNERABILITY TO SIGNIFICANT EVENTS WHICH AFFECT AGGREGATE OUTCOMES SUCH AS BROAD MARKET RETURNS, TOTAL ECONOMY-WIDE RESOURCE HOLDINGS, OR AGGREGATE INCOME
Aggregate risk; Unsystematic risk
In finance and economics, systematic risk (in economics often called aggregate risk or undiversifiable risk) is vulnerability to events which affect aggregate outcomes such as broad market returns, total economy-wide resource holdings, or aggregate income. In many contexts, events like earthquakes, epidemics and major weather catastrophes pose aggregate risks that affect not only the distribution but also the total amount of resources.
