We provide the solution to a fusion of two fundamental problems in
mathematical finance. The first problem is that of maximizing the
expected utility of terminal wealth of an investor who holds a short
position in a contingent claim, and the second is that of maximizing
terminal wealth where the utility function allows the investor to have
negative wealth. Under assumptions of reasonable asymptotic elasticity
on the investor's utility function, we present an optimal investment
theorem and simultaneously treat the corresponding dual problem.
