Your research has found that the returns of all securities in the economy share oil price as one common factor,
Rie=i+iOt+ei
where Rie is the excess return Ri Rf . Consider two well diversified portfolios, A and B with following characteristics:
Answer the following questions (they can all be answered independently).
- (6 points) Suppose Rf = 5% and E(Ot) = 4%. Check if there are arbitrage opportunities in this market.
- (6 points) Suppose A = 0.5% and B = 1%. Calculate the weights of A and B in a zero-beta portfolio. Then describe how you would exploit the arbitrage opportunity and what is the return of doing so.
- (8 points) Given the information provided, What must be the risk-free rate Rf and E(Ot) in this economy if there are no arbitrage opportunities?
