Consider a three$-$factor APT model. The factors and associated risk premiums are:

Factor Risk Premium $(\%)$

Change in gross national product $($GNP$)+6\mathrm{.}5$

Change in energy prices $0\mathrm{.}5$

Change in long$-$term interest rates $+2\mathrm{.}9$

Calculate expected rates of return on the following stocks. The risk$-$free interest rate is $6\mathrm{.}8\%.$

A stock whose return is uncorrelated with all three factors.
