Q1. Consider the multifactor model APT with two factors. Portfolio A has a beta of 1.20 on factor 1 and a beta of 1.50 on factor 2. The risk premiums on the Factor 1 and Factor 2 portfolios are 1% and 7%, respectively. The risk-free rate of return is 4%. If no arbitrage opportunities exist, what is the expected return on portfolio A ? Q2. Consider the single-factor APT. Stocks A and B have expected returns of 12% and 14%, respectively. The risk-free rate of return is 5%. Stock B has a beta of 1.2. If arbitrage opportunities are ruled out, what is the beta of stock A ? Q3.
