Nonlinear Valuation and Non-Gaussian Risks in Finance

Explore how market valuation must abandon linearity to deliver efficient resource allocation.

Targeting practitioners and researchers in financial risk, this book provides new ways of describing and valuing risk to deliver novel solutions to classical financial problems. All solutions are illustrated in detail using financial market data. Problems studied cover univariate and multivariate issues as well as static and dynamic modeling.What happens to risk as the economic horizon goes to zero and risk is seen as an exposure to a change in state that may occur instantaneously at any time? All activities that have been undertaken statically at a fixed finite horizon can now be reconsidered dynamically at a zero time horizon, with arrival rates at the core of the modeling. This book, aimed at practitioners and researchers in financial risk, delivers the theoretical framework and various applications of the newly established dynamic conic finance theory. The result is a nonlinear non-Gaussian valuation framework for risk management in finance. Risk-free assets disappear and low risk portfolios must pay for their risk reduction with negative expected returns. Hedges may be constructed to enhance value by exploiting risk interactions. Dynamic trading mechanisms are synthesized by machine learning algorithms. Optimal exposures are designed for option positioning simultaneously across all strikes and maturities.
