Suppose that two factors have been 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 3.0%. A stock with a beta of 1.3 on IP and 0.7 on IR currently is expected to provide a rate of return of 9%. If industrial production actually grows by 8%, while the inflation rate turns out to be 4.0%, what is your revised estimate of the expected rate of return on the stock?
