Answer:
The risk premium on the market is 8%
Step-by-step explanation:
In solving this example given, we define the method called market risk premium.
Market Risk Premium:
The market risk premium is the difference between the risk free rate and average market return . The market return is often estimated by the return on some market stock index, known as the S&P 500 index
Therefore we apply the capital asset pricing model to compute the market risk premium as follows:
The return of the market portfolio = 13%
The risk free rate =5%
market risk premium = market return - risk free rate
market risk premium = 13% - 5%
market risk premium = 8%
