Institutional investors and fund managers understand they must take risks to generate superior investment returns, but the question is how much risk. Enter the concept of risk budgeting, using quantitative risks measurements, including VaR, to solve the problem. VaR, or value at risk, is a concept first introduced by bank dealers to establish parameters for their market short-term risk exposure. "Risk Budgeting" introduces VaR, extreme VaR, and stress-testing risk measurement techniques to major institutional investors, and shows them how they can implement formal risk budgeting to more efficiently manage their investment portfolios. It includes case studies which show all potential users of VAR and risk budgeting concepts how they can implement this highly disciplined and quantitative risk measurement process themselves. and introduces state- of-the-art VAR techniques and uncovers new mathematical wrinkles.
