Required: Suppose two factors are identified for the U.S. economy: the growth rate of industrial production, IP. and the inflation rate, IR, IP is expected to be 6% and IR 6%. A stock with a beta of 1 on IP and 0.5 on IR currently is expected to provide a rate of return of 10%. If industrial production actually grows by 7%, while the inflation rate furns out to be 8%, what is your best guess for the rate of return on the stock? (Round your answer to 1 decimal place.)
