1. You found two portfolios with returns that are perfectly described by the growth rate of Covid-19 cases in the world, F. Portfolio A has expected rate of return E[RA]=10% and ba=0.35; portfolio B has expected rate of return E[Re]=17% and bg=0.7. The expected growth rate of Covid-19 cases is E[F]=12%. a) Write down the factor equations in deviation from means form. (2 pts) b) Suppose there is no arbitrage opportunity between portfolios A and B, what must the risk-free return be? (4 pts) c) Suppose there is a third portfolio, C, whose growth also only depends on the rate of growth in Covid-19 cases. Its bc is 0.875. What expected rate of return must portfolio Chave so that there is no arbitrage opportunity? (4 pts) 1.
