uppose 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 3% and IR 5%. A stock with a beta of 1 on IP and 0.5 on IR currently is expected to provide a rate of return of 15%. If industrial production actually grows by 4%, while the inflation rate turns out to be 7%, what is your best guess for the rate of return on the stock? (Round your answer to 1 decimal place.)
