Book excerpt: We describe a simple robust technique for incorporating any type of views on expected returns into the Risk parity framework. Optimal allocations with views are characterized by two key properties. First, assets that are not subject to views remain at risk parity. Second, agnostic (cautious) views always result in a more diversified allocation. We further extend this framework to arbitrary initial risk budgets, and suggest an alternative to the Black-Litterman methodology.

Book excerpt: Within the finance literature there is an apparent gap between the inherent risk premium ignorance of a risk parity approach on the one hand and the assumed risk premium clairvoyance of a mean variance approach on the other. We propose a portfolio selection framework that allows an investor to position herself between these two extremes. Depending on the confidence in one's risk premium estimates, the optimal portfolio will be tilted more towards the risk parity portfolio or to the mean variance portfolio. We illustrate the framework for an investor in an asset allocation context.

Download or read book Advances in Risk Parity Portfolio Optimization written by Giorgio Costa Del Pozo and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk parity is an asset allocation strategy that seeks to equalize the risk contributions of the constituent assets in a portfolio. The resulting portfolio is fully diversified from a risk perspective. However, like other asset allocation strategies, risk parity is susceptible to estimation errors. Moreover, its mathematical formulation imposes some fundamental limitations. This thesis aims to modernize risk parity by addressing all of the aforementioned issues. We address the susceptibility to estimation errors through three different frameworks. First, we introduce a robust framework that quantifies estimation error and embeds this information during optimization to construct a robust risk parity portfolio. Our second framework takes a different approach, introducing robustness during the parameter estimation step. This is formulated as a game-theoretic minimax problem to make an optimal investment decision against the most adversarial estimate of our parameters. Our third framework improves the quality of our estimated parameters before optimization takes place. We posit that we can embed the cyclical information of financial markets directly into our estimates, resulting in risk parity portfolios aligned with the current market regime. The result is a Markov regime-switching factor model of asset returns from which we can naturally derive regime-dependent parameters for use during optimization. The final component of this thesis addresses the fundamental limitations of risk parity: its lack of accountability for the investor's risk and reward appetite and its prohibition of short sales. We propose a generalized risk parity framework where the investor's risk and reward appetite define our objective, while still enforcing a desirable degree of risk-based diversification. Moreover, we propose an algorithm that allows us to consider portfolios with short positions. Thus, our generalized framework addresses the fundamental limitations of risk parity while retaining the desirable property of risk-based diversification. The frameworks proposed in this thesis can be used independently or in tandem, depending on the investor's needs and goals. The unifying subject of this thesis is to advance risk parity by addressing its fundamental weaknesses. This is achieved by proposing different frameworks and algorithms, with the overarching property of preserving the interpretability and computational tractability of our solutions.

Download or read book Factor Based Approaches to Risk Parity written by Peter Williams and published by . This book was released on 2014 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper finds that factor based risk parity portfolios are able to outperform other standard asset allocation approaches, including 60/40 and long-only risk parity. By using a group of factors which have negligible correlations with each other and the market, this portfolio generates a stable return stream with little exposure to macroeconomic risks. If these factors are dynamically scaled according to their conditional volatility the portfolio's performance markedly increases. While this portfolio is composed of well known factors it exhibits 'alpha through construction' by scaling out of strategies when their expected returns are lowest and using minimally correlated components.

Download or read book Introducing Expected Returns Into Risk Parity Portfolios written by Thierry Roncalli and published by . This book was released on 2014 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk parity is an allocation method used to build diversified portfolios that does not rely on any assumptions of expected returns, thus placing risk management at the heart of the strategy. This explains why risk parity became a popular investment model after the global financial crisis in 2008. However, risk parity has also been criticized because it focuses on managing risk concentration rather than portfolio performance, and is therefore seen as being closer to passive management than active management. In this article, we show how to introduce assumptions of expected returns into risk parity portfolios. To do this, we consider a generalized risk measure that takes into account both the portfolio return and volatility. However, the trade-off between performance and volatility contributions creates some difficulty, while the risk budgeting problem must be clearly defined. After deriving the theoretical properties of such risk budgeting portfolios, we apply this new model to asset allocation. First, we consider long-term investment policy and the determination of strategic asset allocation. We then consider dynamic allocation and show how to build risk parity funds that depend on expected returns.

Available in PDF, EPUB and Kindle. Book excerpt: While it is often argued that allocation decisions can be best expressed in terms of exposure to rewarded risk factors, as opposed to somewhat arbitrary asset class decompositions, the practical implications of this paradigm shift for the optimal design of the policy portfolio still remain largely unexplored. This paper aims at analyzing whether the use of uncorrelated underlying risk factors, as opposed to correlated asset returns, can lead to a more efficient framework for measuring and managing portfolio diversification. Following Meucci (2009), we use the entropy of the factor exposure distribution as the number of uncorrelated bets (also known as the effective number of bets, or ENB in short), implicitly embedded within a given asset allocation decision. We present a set of formal results regarding the existence and unicity of portfolios designed to achieve the maximum effective number of bets. We also provide empirical evidence that incorporating constraints, or target levels, on a portfolio effective number of bets generates an improvement in out-of-sample risk-adjusted performance with respect to standard mean-variance analysis.

Download or read book The Risks of Risk Parity written by Brandes Institute and published by . This book was released on 2015 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk parity is an asset allocation strategy designed so each asset class contributes equally to overall portfolio risk (as measured by volatility). While risk parity offers potential advantages, its success hinges on key assumptions and a favorable environment for bonds. Like the traditional asset allocation approach it seeks to supplant, risk parity demands a long-term perspective. Unlike the traditional approach, however, risk parity uses a narrow definition of risk and makes no consideration for a critical element in long-term investing: valuations.

Download or read book Generalized Risk Parity Portfolio Optimization written by Giorgio Costa and published by . This book was released on 2020 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The risk parity solution to the asset allocation problem yields portfolios where the risk contribution from each asset is made equal. We consider a generalized approach to this problem. First, we set an objective that seeks to maximize the portfolio expected return while minimizing portfolio risk. Second, we relax the risk parity condition and instead bound the risk dispersion of the constituents within a predefined limit. This allows an investor to prescribe a desired risk dispersion range, yielding a portfolio with an optimal risk-return profile that is still well-diversified from a risk-based standpoint. We add robustness to our framework by introducing an ellipsoidal uncertainty structure around our estimated asset expected returns to mitigate estimation error. Our proposed framework does not impose any restrictions on short selling. A limitation of risk parity is that allowing of short sales leads to a non-convex problem. However, we propose an approach that relaxes our generalized risk parity model into a convex semi-definite program. We proceed to tighten this relaxation sequentially through the alternating direction method of multipliers. This procedure iterates between the convex optimization problem and the non-convex problem with a rank constraint. In addition, we can exploit this structure to solve the non-convex problem analytically and efficiently during every iteration. Numerical results suggest that this algorithm converges to a higher quality optimal solution when compared to the competing non-convex problem, and can also yield a higher ex post risk-adjusted rate of return.

Download or read book Asset Management at Central Banks and Monetary Authorities written by Jacob Bjorheim and published by Springer Nature. This book was released on 2020-09-07 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to the Global Financial Crisis and the COVID-19 pandemic, central banks have used all available instruments in their monetary policy tool-kit to avoid financial market disruptions and a collapse in real economic activities. These actions have expanded the size of their balance sheets and altered the composition of the asset-side. This edited book highlights how these assets are managed, providing an intellectual and practical contribution to an under-researched field of central bank responsibilities. It first reviews the sources and uses of domestic and international assets and how they complement—or possibly conflict with—the implementation of monetary policy goals. Next, the book examines the asset management mandate in a balance sheet context before turning to the investment decision-making process from strategic and tactical asset allocation to investment strategies, risk management, governance, reporting and control. Finally, it presents new developments in the field of managing assets at central banks. The individual chapters are written by central bankers, academics, and representatives from International Financial Institutions, each representing a particular aspect of the asset management practice. Practical and powerful insights from a hall of fame of investors, central bankers and scholars, are packed into this one volume. If you could have only one book on central bank asset management, this would be it. —Peter R. Fisher, Clinical Professor, Tuck School of Business at Dartmouth Jacob Bjorheim draws on his long experience in sovereign asset management to pull together a rich collection of insights from a broad range of expertise. Asset management at central banks has evolved and expanded considerably over the past decade. This book is a timely source of information and guidance. —Guy Debelle, Deputy Governor, Reserve Bank of Australia Central bank balance sheets have grown at a tremendous pace over the last decade and a half. Drawing on contributions from scholars and experienced central bankers from around the world, this timely and insightful book sheds light on how central banks are, and should be, managing their growing balance sheets. —Kjell G. Nyborg, Chaired Professor of Finance, University of Zurich, Author of Collateral Frameworks: The Open Secret of Central Banks Central banks and monetary authorities are charged with, and being held accountable for, managing portfolios of foreign currency assets of unprecedented size. The essays in this admirable book, written by some of the worlds most highly experienced officials, cover the full range of why and how this is currently being done and how new developments are affecting old practices. Interesting conceptually and immensely useful practically. —William White, Senior Fellow at the C.D. Howe Institute, former Head of the Monetary and Economic Department with the Bank for International Settlements (BIS) and chairman of the Economic and Development Review Committee at the OECD An excellent and timely review of modern international reserve management, which ought to be read by everyone working with, or simply interested in, international asset management and finance as well as monetary and economic policy. The spectrum of authors is broad and their combined insight is very valuable. —Tom A. Fearnley, Investment Director, Norwegian Ministry of Finance With “Asset Management at Central Banks and Monetary Authorities”, Jacob Bjorheim has achieved an editorial tour de force. The book assembles the insightful views of the leading experts in the field, both from an academic and practitioners’ perspective. It bridges the gap between the macroeconomics of central banks and the financial management of their reserves. A must read to understand how central banks are special in the group of institutional investors. —Eric Bouyé, Head of Asset Allocation and Quantitative Strategies, Treasury Department, The World Bank The balance sheet is a large and important toolbox for any central bank and specifically the foreign exchange reserves constitute one the more powerful of these tools. This book provides excellent insight in the various perspectives of managing reserves at a central bank. —Heidi Elmér, Director of Markets Department, Severiges Riksbank The world of international reserves has changed since the global financial crisis. In this volume, Jacob Bjorheim has assembled a stellar cast of experts to explain how and what that means for reserves management. With chapter authors like Andrew Ang, Jennifer Johnson-Calari, Robert McCauley, Ravi Menon, Simon Potter and Philip Turner, it is a book that every reserve manager must read. —Eli Remolona, Professor of Finance and Director of Central Banking, Asia School of Business in collaboration with MIT Sloan Jacob Bjorheim has succeeded in bringing together a first-class team of experts, and organising their contributions in an articulated journey from the central banks’ policy mandate to their asset management practices. An indispensable post-crisis update of the subject and a a required reading for anyone professionally involved with central bank’s asset management, or simply curious about a topic benefitting otherwise from limited research. —Louis de Montpellier, Former Global Head, Official Institutions Group, SSGA, and former Deputy Head, Banking Department, Bank for International Settlements (BIS), Basel At last, a book that shares with a wider audience, deep insight in a unique, challenging and ethical approach of asset management developed and implemented in the secretive world of central banks. If you wonder how to manage funds that stand ready for use at short notice in times of stress then this book is for you. Two features make it such a valuable read and a must-have reference: First, the very comprehensive list of themes covered from a rich diversity of angles. Second, the very impressive list of prominent institutions and authors that have contributed and shared their analysis and practical approaches of the issues presented. What is better than to get the information directly from first-hand practitioners, experts and managers themselves in their own words? —Jean-Pierre Matt, Former Head of Financial Analysis at the Bank for International Settlements (BIS) and founder of Quanteis This book holds the promise to become the go-to guide for anyone wishing to learn more about the management of official foreign exchange reserves. Central bankers in particular, but also those providing services to central banks, will find benefit from the broad scope in subject matter and varied perspectives being presented. I am yet to see a compendium on official reserve management with similar reach in subject matter. —Leon Myburgh, Former Head Financial Markets Department, South African Reserve Bank (SARB), Pretoria This is an immensely timely book at a time when central bank operations, and their balance sheets, remain “larger for longer”. Following the Financial Crisis 10 years ago, and with the Covid-19 Recession about to break, central bank balance sheets are at the forefront of the authorities’ response to economic issues as never before. Yet the management of their now large-scale assets remains a little known and little studied area. The authors of this book combine extensive technical and practical experience, and their observations will fill an important gap in the literature at a critical time. —Freyr Hermannsson, Former Head of Treasury, Central Bank of Iceland, Reykjavík

Download or read book Extending Risk Parity Beyond Volatility written by Michael Frei and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in risk management and lessons from the 2007 financial crisis have increased interest in asset allocation strategies that focus on portfolio risk. The risk parity model has gained interest amongst academics and practitioners due to its intuitive concept of diversifying risk by equalizing the risk contributions of the portfolio constituents. So far academic research has focused on using solely volatility as a risk measure within risk parity. This paper extends the risk parity model by incorporating VaR and CVaR as risk measures and providing analytical and numerical definitions of the problems. We specify an extended multi-period and multi-asset class risk parity model and test it using historic data and simulated returns. Our results show that we are able to outperform common benchmark strategies both on an absolute as well as relative basis. Furthermore, the extended risk parity model outperforms the volatility-constrained risk parity strategy and achieves a superior risk-adjusted performance.

Download or read book Flexibility and Real Estate Valuation under Uncertainty written by David Geltner and published by John Wiley & Sons. This book was released on 2018-02-19 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides a revolutionary conceptual framework and practical tools to quantify uncertainty and recognize the value of flexibility in real estate development This book takes a practical "engineering" approach to the valuation of options and flexibility in real estate. It presents simple simulation models built in universal spreadsheet software such as Microsoft Excel®. These realistically reflect the varying and erratic sources of uncertainty and price dynamics that uniquely characterize real estate. The text covers new analytic procedures that are valuable for existing properties and enable a new, more profitable perspective on the planning, design, operation, and evaluation of large-scale, multi-phase development projects. The book thereby aims to significantly improve valuation and investment decision making. Flexibility and Real Estate Valuation under Uncertainty: A Practical Guide for Developers is presented at 3 levels. First, it introduces and explains the concepts underlying the approach at a basic level accessible to non-technical and non-specialized readers. Its introductory and concluding chapters present the important “big picture” implications of the analysis for economics and valuation and for project design and investment decision making. At a second level, the book presents a framework, a roadmap for the prospective analyst. It describes the practical tools in detail, taking care to go through the elements of the approach step-by-step for clarity and easy reference. The third level includes more technical details and specific models. An Appendix discusses the technical details of real estate price dynamics. Associated web pages provide electronic spreadsheet templates for the models used as examples in the book. Some features of the book include: • Concepts and tools that are simple and accessible to a broad audience of practitioners; • An approach relevant for all development projects; • Complementarity with the author's Commercial Real Estate Analysis & Investments—the most-cited real estate investments textbook on the market. Flexibility and Real Estate Valuation under Uncertainty: A Practical Guide for Developers is for everyone studying or concerned with the implementation of large-scale or multi-phase real estate development projects, as well as property investment and valuation more generally.

Download or read book Diversifying Risk Parity written by Harald Lohre and published by . This book was released on 2014 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Striving for maximum diversification we follow Meucci (2009) in measuring and managing a multi-asset class portfolio. Under this paradigm the maximum diversification portfolio is equivalent to a risk parity strategy with respect to the uncorrelated risk sources embedded in the underlying portfolio assets. Our paper characterizes the mechanics and properties of this diversified risk parity strategy. Moreover, we explore the risk and diversification characteristics of traditional risk-based asset allocation techniques like 1/N, minimum-variance, or risk parity and demonstrate the diversified risk parity strategy to be quite meaningful when benchmarked against these alternatives.
