The financial market is described by Kabanov's model of foreign exchange markets over a finite probability space and finite-horizon discrete time steps. This framework allows us to compare vector-valued portfolios under a partial ordering, so that our model does not require liquidation into some numeraire at terminal time.\n  We embed the vector-valued portfolio problem into the set-optimization framework, and generate a problem dual to portfolio optimization.
