Institutionelle Anleger, Fonds- und Portfoliomanager müssen Risiken eingehen, wenn sie Spitzengewinne erzielen wollen. Die Frage ist nur wieviel Risiko. Risk Budgeting liefert die Antwort auf diese Frage. Mit Hilfe quantitativer Methoden zur Risikomessung, einschließlich der Value at Risk-Methode läßt sich das Risiko ermitteln und bewerten. Value at Risk (VaR) ist ein Verfahren zur Risikobewertung, das Fondsmanager verstärkt zum Risikomanagement einsetzen. Dieses Buch bietet eine fundierte Einführung in die VaR-Methode sowie in Verfahren zur Risikomessung bei Extremereignissen und Krisenszenarien (Stress Testing). Darüber hinaus erklärt es, wie man mit Hilfe des Risk Budgeting ein effizienteres Portfoliomanagement erreicht. Das einzige Buch auf dem Markt, das Risk Budgeting und VaR - zwei brandaktuelle Themen im Portfoliomanagement - speziell für institutionelle Investment- und Portfolio-Manager aufbereitet.
Praise for Risk budgeting
"Professor Pearson has raised the bar for books on market risk. Moving beyond descriptions of VaR calculation and stress testing, he provides careful discussions of both the refinements and the limits of the VaR technique. Even more importantly, this book provides structure to the heretofore vague idea of 'risk budgeting.' "
-Charles Smithson, Managing Partner, Rutter Associates
"Pearson has written an excellent resource for risk management practitioners who actually need to compute and use VaR. Numerous concrete examples make a broad range of VaR techniques accessible to the people who actually need to use them. The book also provides tangible applications of risk budgeting, a term often used but rarely made relevant. Pearson has put meat on the bones for plan sponsors who want to actually employ risk budgeting techniques."
-Bennett Golub, Co-head of Risk Management and Analytics,
Founding Partner, BlackRock
"An excellent book. This text provides a bridge from the theoretical to the practical, and clears the fog between the buzzwords of risk budgeting and the realities of a useful new portfolio management tool. Pearson's writing is well balanced between needed academic foundation and the practicalities of managing portfolios."
-Rob Roy, Director, Cash and Investments, Adventist Health System
"I just wish I could summarize this book as ably as Professor Pearson summarizes the voluminous literature on Value-at-Risk. Unfortunately, I suspect no further compression is possible. To reduce the risk of reading rubbish, your best bet is to read this book."
-Dr. Peter Carr, Senior Consultant, Risk Capital Management
