Specific risk

In the Capital Asset Pricing Model specific risk is the component of total risk which is fully diversified away by rational investors by holding well-diversified portfolios of investments.

Under the CAPM, there is therefore no additional reward to investors for accepting specific risk.

Also known as Unsystematic risk, Diversifiable risk, or Idiosyncratic risk.
