Suppose there are n assets which are uncorrelated. (They might
be n different “wild cat” oil well prospects.) You may invest in any one, or in
any combination of them. The mean rate of return r¯ is the same for each asset,
but the variances are different. The return on asset i has a variance of σ2
i for
i = 1, 2, . . . , n.
(a) Show the situation on an r¯-σ diagram. Describe the efficient set.
