Market Risk Management for Hedge Funds: Foundations of the Style and Implicit Value-at-Risk

توضیحات

Market Risk Management for Hedge Funds provides a clear understanding of the fundamentals of quantitative risk measurement, as well as covering the technical aspects of the Style Value-at-Risk and the Implicit Value-at-Risk measurements applied to hedge funds.

The book is divided into three parts. The first part explains the fundamentals of the Style and Implicit Value-at-Risk measurements as seen through the eyes of the alternative industry practitioner. It describes the effects of the ongoing institutionalisation of the hedge fund domain and examines one of the most important features of an absolute return industry. This section also addresses the issues of active and passive hedge fund indices, the failure of both approaches to provide a good representation of hedge funds, and finally provides a qualitative insight of the four dimensions of risk management for the hedge fund investor.

Part two is devoted to Style Value-at-Risk measurement, presenting the original model as well as out-of-the-sample back-testing. It also proposes a new parameterisation of the Style Model, addresses the issue of the annualisation of risk measurement for hedge funds, and illustrates a fundamental difference between traditional and alternative investments.

Part three presents the Best Choice Implicit Model by addressing the limits of the Style analysis and introducing the Best Choice Implicit Value-at-Risk. It also addresses the issue of hedge fund return cloning within the Best Choice Implicit Model framework, and details the Risk Budgeting approach that can be used with these types of models. Finally, it examines the forecasting power of Value-at-Risk exception monitoring, and provides some adjustments to Value-at-Risk that are particularly relevant during financing crises.
