1. Suppose that two factors have been identified for the U.S. economy: thegrowth rate of industrial production, IP, and the inflation rate, IR. IP isexpected to be 3%, and IR 3.3%. A stock with a beta of 1.8 on IP and 1.3on IR currently is expected to provide a rate of return of 15%. If industrialproduction actually grows by 6%, while the inflation rate turns out to be5.2%, what is your revised estimate of the expected rate of return on thestock? (Do not round intermediate calculations. Round your answer to1 decimal place. Omit the "%" sign in your response.)2.Assume that security returns are generated by the single-index model,Ri = i + iRM + eiwhere Ri is the excess return for security i and RM is the markets excess return.
