Question: Two risky assets have returns generated by the single factor (CAPM) model R 1 R f = 2(R m - R f )+ e 1
Two risky assets have returns generated by the single factor (CAPM) model
R1 Rf = 2(Rm - Rf)+ e1.
R2 Rf = 0.8(Rm - Rf)+ e2.
Stdev(Rm) = 0.20, stdev(e1) = stdev(e2) = 0.20, and covar(e1,e2) = 0. Rf = 0.02 is the riskfree rate. Stdev is short for standard deviation (square root of variance).
- Compute the standard deviation of asset 1, asset 2, and their covariance.
- Compute the of the equal-weighted portfolio of the two stocks.
- Suppose E[Rm] = 0.10. Compute the expected return on the equal-weighted portfolio of stocks 1 and 2.
