Finance[ edit ] In financea common approach for measuring risk premia is to compare the risk-free return on T-bills and the risky return on other investments using the ex post return as a proxy for the ex ante expected return.

In the stock market the risk premium is the expected return of a company stock, a group of company stocks, or a portfolio of all stock market company stocks, minus the risk-free rate.
The return from equity is the sum of the dividend yield and capital gains. The risk premium for equities is also called the equity premium. This risk premium is an unobservable quantity since it is not known what the expected rate of return on equities is for the average market participant even though each individual participant knows their own expectation.
Nonetheless, most people believe that there is a risk premium built into equities, and this is what encourages investors to place at least some of their money in equities.
