 InvestHub.com's Finance Dictionary and Glossary of Investment Terms Equilibrium market price of risk Definition 1.
The slope of the capital market line (CML). Since the C.M.L. represents the expected return offered to compensate for a perceived level of risk, each point on the line is a balanced market condition, or equilibrium. The slope of the line determines the additional expected return needed to compensate for a unit change in risk. The equation of the CML is defined by the capital asset pricing model.
