Unsystematic risk (risk that can be diversified away) is not rewarded. Systematic risk is the risk for which investors are compensated. Systematic risk is that part of total risk that is correlated with the market and related to changes in macroeconomic variables (such as changes in interest rate volatility). Standard deviation of returns of the market portfolio is a measurement of systematic risk.
