Consider the following two stocks: Stock "True" Expected Return Beta ABC DEF 10.0% 12.5% 1.1 1.8 The risk-free rate is 2% and the expected market return is 7%. a) According to the CAPM, which stock is the better buy and why? [2 marks] b) Suppose returns follow a single-factor structure, and the factor is the market return. Given the above information, is there an arbitrage opportunity?
