Consider a single-factor model economy. Portfolio M has a beta of 1.0 on the factor and portfolio P has a beta of 0.5 on the factor. The expected returns on portfolios M and P are 11% and 10.5%, respectively. Assume that the risk-free rate is 6% and that arbitrage opportunities exist. Suppose your funds size is 200,000, i.e., both of your long and short position will be 200,000. What would be your expected profit from forming a zero-beta portfolio Z and taking the arbitrage opportunity? (10 marks)
