Exercise 9 (A) An investor seeks an efficient n-asset portfolio with a fixed return equal to p. Otherwise the only other constraint is the budget condition. Show by solving a QP-problem with two equality constraints, that (in the usual notation) the optimal allocation vector is the solution of: 'c bp ap b e+ d d Sx= Show that the same result is obtained from the optimal portfolio equations derived in lectures in terms of the investor's risk aversion parameter t.
