8 (Correlation and Diversification)
Assume we have two stocks, A and B, show that a particular combination
of the two stocks produce a risk-free portfolio when the correlation between
the return of A and B is -1.
9 (Portfolio allocation)
Suppose R₁ and R2 are returns of 2 assets and with expected return and
variance respectively r₁ and 72 and variance-covariance σ2, 0%½ and σ12. Find
−∞ ≤ w ≤ ∞ such that the portfolio wR₁ + (1 - w) R₂ has the smallest
risk.
7 (Multivariate random variable)
Suppose X, €1, €2, €3 are IID N(0, 1) and
Y2
Y₁ = 0.2 0.8X + €1, Y₂ = 0.3 +0.7X+ €2, Y3 = 0.2 + 0.9X + €3.
=
(In models like this, X is called the common factors of Y₁, Y₂, Y3.)
Y = (Y1, Y2, Y3).
(a) Find E(Y) and cov(Y).
(b) What can you observe from cov(Y).
