Over the last two decades, risk-sensitive control has evolved into an innovative and successful framework for solving dynamically a wide range of practical investment management problems.This book shows how to use risk-sensitive investment management to manage portfolios against an investment benchmark, with constraints, and with assets and liabilities. It also addresses model implementation issues in parameter estimation and numerical methods. Most importantly, it shows how to integrate jump-diffusion processes which are crucial to model market crashes.With its emphasis on the interconnection between mathematical techniques and real-world problems, this book will be of interest to both academic researchers and money managers. Risk-sensitive investment management links stochastic control and portfolio management. Because of its distinct emphasis on integrating advanced theoretical concepts into practical dynamic investment management tools, this book stands out from the existing literature in fundamental ways. It goes beyond mainstream research in portfolio management in a traditional static setting. The theoretical developments build on contemporary research in stochastic control theory, but are informed throughout by the need to construct an effective and practical framework for dynamic portfolio management.This book fills a gap in the literature by connecting mathematical techniques with the real world of investment management. Readers seeking to solve key problems such as benchmarked asset management or asset and liability management will certainly find it useful.

We consider an optimal risk-sensitive portfolio allocation problem accounting for the possibility of cascading defaults. Default events have an impact on the distress state of the surviving stocks in the portfolio. We study the recursive system of non-Lipschitz quasi-linear parabolic HJB-PDEs associated with the value function of the control problem in the different default states of the economy. We show the existence of a classical solution to this system via super-sub solution techniques and give an explicit characterization of the optimal feedback strategy in terms of the value function. We prove a verification theorem establishing the uniqueness of the solution. A numerical analysis indicates that the investor accounts for contagion effects when making investment decisions, reduces his risk exposure as he becomes more sensitive to risk, and that his strategy depends non-monotonically on the aggregate risk level.

A new jump diffusion regime-switching model is introduced, which allows for linking jumps in asset prices with regime changes. We prove the existence and uniqueness of the solution to the risk-sensitive asset management criterion maximisation problem in this setting. We provide an ODE for the optimal value function, which may be efficiently solved numerically. Relevant probability measure changes are discussed in the appendix. The approach of Klebaner & Lipster (2014) is used to prove the martingale property of the relevant density processes.

Dieser Band füllt eine echte Marktlücke. "Goldman Sach's Modern Investment" gibt eine Einführung in moderne Investment Management Verfahren, wie sie von Goldman Sachs Asset Management verwendet werden, um erstklassige Investitionsrenditen zu erzielen. Erläutert werden u.a. die moderne Portfoliotheorie (Portfoliodiversifikation zur Risikostreuung), Capital Asset Pricing (Verfahren zur Ermittlung des Risiko-Rendite-Austauschverhältnisses von Finanzanlagen, bei dem der unterschiedliche Risikogehalt von Finanztiteln berücksichtigt wird) sowie eine Reihe aktueller Themen wie z.B. strategische Portfoliostrukturierung, Risikobudgetierung und aktives Portfolio Management. Hier erhalten Sie die Mittel an die Hand, um die Goldman Sachs Asset Management Methode für sich selbst umzusetzen. Das von Fischer Black und Bob Litterman gemeinsam entwickelte Black-Litterman Asset Allocation Model gehört zu den angesehensten und meist verwendeten Modellen zur Portfoliostrukturierung. Litterman und seine Asset Management Group sind oft die treibende Kraft, wenn es um Portfoliostrukturierung und Investmententscheidungen der 100 international größten Pensionsfonds geht.

This volume provides the definitive treatment of fortune's formula or the Kelly capital growth criterion as it is often called. The strategy is to maximize long run wealth of the investor by maximizing the period by period expected utility of wealth with a logarithmic utility function. Mathematical theorems show that only the log utility function maximizes asymptotic long run wealth and minimizes the expected time to arbitrary large goals. In general, the strategy is risky in the short term but as the number of bets increase, the Kelly bettor's wealth tends to be much larger than those with essentially different strategies. So most of the time, the Kelly bettor will have much more wealth than these other bettors but the Kelly strategy can lead to considerable losses a small percent of the time. There are ways to reduce this risk at the cost of lower expected final wealth using fractional Kelly strategies that blend the Kelly suggested wager with cash. The various classic reprinted papers and the new ones written specifically for this volume cover various aspects of the theory and practice of dynamic investing. Good and bad properties are discussed, as are fixed-mix and volatility induced growth strategies. The relationships with utility theory and the use of these ideas by great investors are featured.
