Answer:
C.13.6 percent
Step-by-step explanation:
GDP Market STOCK
ER 7,2% 2,4% 13,6% Expected Return of Investment Rf 4,00% Risk-Free Rate
Bi 1,2 0,6 1,0 Beta of the Investment
(Erm-Rf) 6,00% 4,00% 9,60% Market Risk Premium
It's necessary to calculate how much impact each item has with the corresponding Beta in the stock
Then, to know the impact of exposure to the Aluminum market, we have to multiply the risk premium of 4% by the beta of 0,6
Then, to know the impact of the exposure to GDP, we do the same procedure, we multiply the risk premium of GDP by the beta of 1,2.
With these calculations we reach how much of the return on this stock corresponds to the market and then we add 4% of risk free.
