This book aims to cover the following general topics: development and assessment of theories for evaluating commodity risk; the role of derivative securities in managing commodity risk; and, an assessment of the actual management of commodity risk in specific situations. The primary contribution of the book is the explicit development of the often overlooked connection between risk management and speculation. The central theme is to demonstrate that commodity risk management decisions require an in depth understanding of speculative strategies. To this end, this book aims to provide a unified treatment of important concepts and techniques that are useful in applying derivative securities in the management of risk arising in commodity markets.
