Diversifiable risk is the possibility that there will be a change in the price of a security because of the specific characteristics of that security. Diversification of an investor's portfolio can be used to offset and therefore eliminate this type of risk.

What does Diversifiable risk include?

Unsystematic risk (also called diversifiable risk) is risk that is specific to a company. This type of risk could include dramatic events such as a strike, a natural disaster such as a fire, or something as simple as slumping sales. Two common sources of unsystematic risk are business risk and financial risk.

What is Diversifiable risk and Nondiversifiable risk?

In this framework, the diversifiable risk is the risk that can be “washed out” by diversification and the nondiversifiable risk is the risk which cannot be diversified away. It appears to us that the decomposition of risk into its components is in some cases vague and in most cases imprecise.
