A Portfolio Theory of Market Risk Load

Abstract
In insurance pricing, it is convenient to split the total risk load for a policy into the market risk load and the insurer specific risk load, and calculate each separately. The market risk load represents an equilibrium price on a competitive insurance market. A portfolio theory is developed along the line of the classic CAPM, where a policy's market risk load is a function of its systematic risk and the risk load of the entire insurance market. The model is mathematically proved. As a corollary a formula for the risk adjusted discount rate is obtained. Issues about the real world application and testing are also discussed.
