Capital Asset Pricing Model
Diversifiable risk commonly known as unsystematic risk entails the risks that affects a particular security or industry. The risk can be reduced by the investor diversifying his investments portfolio in different stocks and different industries. Undiversifiable risks can also be termed as systematic risks which affect the whole market without effects on a particular industry or stock. Systematic risk is hard to predict when it will occur and also cannot be avoided completely though it can be mitigated.
