This book is a comprehensive, quantitative treatment of the theory and practice of portfolio management as practised in India. Across 21 chapters, it spans the full investment-management value chain—asset classes and their valuation, portfolio theory (MPT, CAPM and market efficiency, behavioural finance), risk measurement, active and passive equity and fixed-income strategy, performance attribution, and rebalancing—set within the Indian taxation, regulatory and ethical framework, including the SEBI (Portfolio Managers) Regulations 2020. Every concept is built from first principles and demonstrated through worked examples, supported by exhibits, statutory extracts, sample questions and caselets. The September 2025 Workbook Version, published exclusively by Taxmann, is the official text for the NISM-Series-XXI-B certification examination and also serves as a standalone reference for PMS professionals, advisers, and finance students.
