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 2%, and IR 4%. A stock with a beta of 1.2 on IP and 0.7 on IR currently is expected to provide a rate of return of 10%. If industrial production actually grows by 5%, while the inflation rate turns out to be 7%, what is the revised estimate of the expected rate of return on the stock?
