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 4% and ir 7%. a stock with a beta of 1 on ip and 0.5 on ir currently is expected to provide a rate of return of 13%. if industrial production actually grows by 5%, while the inflation rate turns out to be 8%, what is your best guess for the rate of return on the stock? (round your answer to 1 decimal place.)
