Abstract: For a locally bounded local martingale S, we investigate the vector space generated by the convex cone of maximal admissible contingent claims. By a maximal contingent claim we mean a random variable (H⋅S)∞, obtained as a final result of applying the admissible trading strategy H to a price process S and which is optimal in the sense that it cannot be dominated by another admissible trading strategy. We show that there is a natural, measure-independent, norm on this space and we give applications in Mathematical Finance.
