    Description of Option Valuation under Stochastic Volatility

    This book provides an advanced treatment of option pricing for traders, money managers, and researchers. Providing largely original research not available elsewhere, it covers the new generation of option models where both the stock price and its volatility follow diffusion processes.

    These new models help explain important features of real-world option pricing that are not captured by the Black-Scholes model. These features include the 'smile' pattern and the term structure of implied volatility. The book includes Mathematica code for the most important formulas and many illustrations.

    Reviews

    "This exciting book is the first one to focus on the pervasive role of stochastic volatility in option pricing. Since options exist primarily as the fundamental mechanism for trading volatility, students of the fine art of option pricing are advised to pounce."
    - Peter Carr, Ph.D., Principal, Banc of America Securities

    "I found this book extremely interesting, and valuable for both academics and practitioners. It treats many important aspects of the stochastic volatility problem with novel methods. I especially liked the treatment of the term structure of implied volatility in Chapter 6. This book is a very nice contribution to the literature."
    - Prof. Nizar Touzi, Department of Mathematics, University of Paris I, Leading expert on stochastic volatility models

    "This book is an impressive collection of methods and results. I found Chapter 7 on equilibrium models particularly helpful, as very often people 'fudge' the discussion of the volatility risk premium by making simple assumptions."
    - Prof. Stephen Taylor, Accounting and Finance, Lancaster University
