This original book examines how investment theory and regulatory constraints are linked to the professional processes of portfolio investments, and how the principles of Islam as defined by sharia fit into these processes. It also explores the measures required to create and grow a global Islamic asset management industry. Established on a foundation of Modern Portfolio Theory, the book extends the theory to include asset management based on sharia. Chapters also consider how ethical investing is quickly becoming the driving force of the $100 trillion asset management industry. Taking a practical approach, John A. Sandwick, M. Kabir Hassan and Pablo Collazzo compare conventional and sharia portfolio performance and risk through measurement tools commonly used in asset management, including Sharpe ratio, standard deviation, Value at Risk, annualized mean return, and correlation. They map conventional portfolio construction and optimization, then reproduce the same processes with real-world, sharia-compliant portfolios. This book will be critical reading for scholars and students of Islamic economics and finance, Islamic studies, and financial regulation. Considering Islamic asset management as a unique function of Islamic finance, this book will also be a useful resource for practitioners and finance professionals.
