The Legacy of Modern Portfolio Theory

Abstract

Fifty years have passed since the publication of Harry Markowitz9s article on portfolio selection, setting forth the ground-breaking concepts that have come to form the foundation of what is now popularly referred to as Modern Portfolio Theory (MPT). In this article the authors briefly explain the theory underlying MPT and using illustrations highlight the application of MPT to the current practice of asset management and portfolio construction. The authors also survey most of the relevant research that has directly or indirectly been either an outcome of MPT or has contributed to the implementation of MPT.
