Consider the expected return and standard deviation of the following two assets:
Asset 1: E[r1]=0.1 und σ1=0.3
Asset 2: E[r2]=0.2 und σ2=0.4
(a) Draw (e.g. with Excel) the set of achievable portfolios for the cases: (i) ρ12=-1, (ii) ρ12=0.
(b) Suppose ρ12=0. Which portfolio has the minimal variance? What is the minimal variance?
