(1)Suppose that there are two independent economic factors, F₁ and F₂. The following are three securities:

SecurityXYZ

Beta on factor 11.52.21

Beta on factor 22.0-0.23

Expected return0.350.270.40

A)Write down the factor models for securities X, Y, and Z.

B)Write down the factor model for a portfolio composed of W₁ units of X, W₂ units of Y, and W₃ units of Z.

C)Construct a portfolio whose beta on factor one is 1 and whose beta on factor two is 0. What is its expected return?
