Back in the distant days of the mid‐1980s I began my career focused on equity markets. Over the next two decades, the abundance of price and volume data, along with the relatively limited set of variables required to describe equity risk, led to the development of fundamental and statistical equity risk models that are now ubiquitous across the asset management industry.
In due course it became obvious to me that in order to understand investment risk in all its forms, some knowledge of fixed‐income markets and products was also necessary. Many years before my association with BlackRock, I came across a book, Risk Management: Approaches for Fixed Income Markets (2000) by Bennett W. Golub and Leo M. Tilman. I remember reading it with some fascination. The statistical constructs were, at least in part, similar to those used in equity markets. However, the markets themselves were very different. Nonetheless, the rigor of the discussions and the practicality of the contents were incredibly useful to me back then.
Some years later Ben Golub and I became colleagues when BlackRock acquired Merrill Lynch Investment Management, where I was then the head of its Risk & Quantitative Analysis group in London. This brought me for the first time into contact with BlackRock's fixed‐income analytics and risk management teams. My equities background combined with BlackRock's fixed‐income expertise made for a good match, and I was appointed the co‐head with Ben Golub of a merged Risk & Quantitative Analysis group.
Over the subsequent 16 years, much has taken place in both markets and risk management. The contrasts between equities and fixed‐income investing were, in many respects, palpable. Some of the characteristics of fixed‐income securities became clearer to me, such as the limited trading and even more limited price data, the lags in the availability of the limited amount of pricing data, the astounding number of individual securities, and the nonstandard terms and conditions of securities. Real‐world risk management meant making necessary compromises from the equity ideal.
Currently, changes and reforms are moving fixed‐income markets somewhat closer to the more idealized equity markets, making certain types of analyses that were routine in the equity markets partially available for fixed‐income securities.
The last 16 years have also contained some major market events, including the Global Financial Crisis and the Coronavirus pandemic, that challenged the notion that even exchange markets operate efficiently all the time. Some of the later chapters in this book that focus on financial crises contain lessons that we learned that are genuinely worth remembering.
This book introduces the notion of an Investment Risk Management Paradigm (IRMP). This is particularly useful as a reminder of the need to enforce consistent levels of rigor across all of the firm's investment processes. Having a formal notion of this standardization has been extremely useful, especially when investment processes change or activities are added.
History will not be kind to some notions of risk management that turn out to be formalized manifestations of self‐delusion. Other analytics or frameworks will better last the test of time. But while I am certain that some of the notions described in this book will eventually need to change, just as many were eventually edited out of the first edition, many will stand the test of time. This book presents techniques and practices that are actually used and are actually useful. I recommend it to investors and risk managers who wish to get an insight into how investment risk management is contemporaneously practiced at a major global multi‐investment process asset manager.

Changing market dynamics, technological advances, and geopolitical stresses have transformed investment risk management. As new and bespoke products have emerged, new risks and additional complexities have driven advances in risk management processes and analytics. Consider, for example, all the forced and rapid innovations that arose from the Coronavirus pandemic. Given the abundance of change, risk managers have had to adapt their processes and tools to address market turbulence, structural bond market changes, product complexity, and increased regulatory oversight. Additionally, risk managers have learned to take advantage of some of these technological advances, resulting in better analytics and the ability to analyze bigger and broader data sets. An intellectually curious risk management culture, coupled with rigorous risk management processes and technological competence, facilitates risk managers' ability to rapidly and effectively adapt to new circumstances.
Recognizing the dynamic nature of investment risk management informs us that it is almost certain that some of the ideas and methodologies presented in this book will inevitably become obsolete themselves. Similarly, there inevitably are important omissions, either intentionally due to the limitations of time or are outside the wisdom and firsthand knowledge of the authors.
This book is a heavily edited and expanded edition of Risk Management: Approaches for Fixed Income Markets (2000) by Bennett W. Golub and Leo M. Tilman (the first edition). In the 23 years following the original English language publication, much has happened to reshape the investment risk management landscape. For example, the heightened attention by markets and investors to ESG (environmental, social, and governance) characteristics was never envisioned when the original book was published. The definitive book on ESG risk management has probably not been written yet; this book intentionally omits much of that topic, while the profession awaits a conclusive state‐of‐the‐practice volume. Also, while currently a hot topic and one that certainly has demonstrated the ability to generate multiple risk management failures, this book is intentionally silent on the risk management of cryptocurrencies; we await those markets' risk management processes maturing.
The technological intensity of investment risk management has increased dramatically. Twenty‐three years ago, technology was not necessarily at the forefront of most investment management firms. Now, technology is one of the critical success factors—allowing firms to continue to evolve to meet clients' needs, respond to market changes and regulatory requirements, and create operational efficiencies and scale. With improvements in technology, firms are now able to perform tasks that were previously technologically impossible or would take too much time or too much expensive hardware to be useful. When editing sections of the original book for inclusion in this new edition, references to analytic techniques that involved compromising accuracy for computational efficiency were removed from the manuscript; there is much less need to compromise precision for the sake of economizing computational resources. The implications of Moore's Law, broadly speaking, continue to make more and more computational resources economical. Cloud‐based applications, for example, can summon massive amounts of computational power on demand. Organizations can store, analyze, manipulate, and synthesize what would have been unimaginable amounts of data more cheaply and quickly than ever before. The sophisticated and creative use of technology, has become an essential part of effective investment risk management. Having the right technology to manage risk is no longer a luxury; it is a necessity.
BlackRock's commitment to innovation and the use of technology has been one of the key drivers of its ongoing robust growth. Developing and evolving Aladdin and leveraging technology has been part of BlackRock's founding vision and has enabled the firm to become a massive scale operator, highly efficient, integrated, and dynamic. As the firm grows and technology evolves, Aladdin continues to be a best‐in‐class solution, used by BlackRock to operate efficiently at scale. The same Aladdin technology used by BlackRock is also available and heavily used by many major global financial institutions.
The motivation for this book originated due to an inquiry from a BlackRock client about when the first edition would be revised. Initially, this seemed to be a relatively straightforward task, and the project was initiated in 2017. At first, the plan was to update data, tables, and exhibits and remove topics that were no longer relevant. However, after this editing process, it became apparent that simply updating the data and removing obsolete sections would be sorely inadequate given how much markets, products, and risk management have evolved. Instead, it became clear that if the original book were to be properly updated, a substantial expansion of the topics covered would be required. That, of course, made creating the second edition a materially greater task. Given my then current role as chief risk officer of BlackRock, this task would have been beyond my ability to complete. In 2018, I concluded that if we expanded the scope of the book, the only feasible path forward was to ask my fellow BlackRock colleagues to contribute their expertise and enthusiasm and author or coauthor the needed chapters. Unlike the original book, which was written as a unified whole in a single voice, the new edition would include chapters on a wide range of topics written by many authors.
Bringing together BlackRock's leaders in risk management, portfolio management, trading, financial modeling, psychology, and analytics, this successor book to the first edition, now titled BlackRock's Guide to Fixed-Income Risk Management, represents a combination of revised and updated chapters from the original book and a collection of new standalone chapters covering a range of investment risk management topics. Each chapter has been authored by BlackRock's current or former senior subject matter experts. While the book focuses primarily on fixed‐income practices, analytics, and models, many of the concepts presented are equally meaningful in a multi‐asset context. This book can first be considered a practitioner's guide to fixed‐income risk management, leveraging BlackRock's overall investment risk management framework for operating a viable risk management program at scale, heterogeneity, and complexity.
This book is organized into three sections and covers the following themes:
An Approach to Fixed‐Income Investment Risk Management
Fixed‐Income Risk Management—Then and Now
Lessons from the Credit Crisis and Coronavirus Pandemic
In Section I, we describe the pillars of BlackRock's Investment Risk Management Paradigm (IRMP). This paradigm evolved over many years as a tool to bring consistency and structure to BlackRock's risk management activities across its various investment management businesses to ensure that risks are properly identified, measured, governed, and reconciled with actual performance. The IRMP rests upon on the following five pillars:
Ex ante risk measurement
Risk governance (i.e., having and maintaining agreed upon levels of risks)
Portfolio manager risk-return awareness
Performance attribution
Performance analysis
Each component of the paradigm is discussed in detail in one or more of the following chapters. Given the various risks to which portfolios are exposed and the diversity of measurements available, several chapters expand upon the first pillar, ex ante risk measurement. Examples and case studies are incorporated to help illustrate the risk management approaches and analytics presented.
Chapter 1 provides an overview of risk management at BlackRock and discusses several elements that underpin a strong risk management program. The chapter reinforces the importance of governance and oversight and introduces BlackRock's approach to investment risk management. To be clear, though, establishing a comprehensive and pervasive risk management program and culture requires commitment and support from all levels of an organization, starting with senior management. My colleagues and I were fortunate to be able to develop our ideas and methodologies in such an environment. This chapter was coauthored by myself and Rick Flynn, managing director in the Risk & Quantitative Analysis group.
Chapter 2 presents parametric approaches to risk management and was initially included in the first edition. This chapter aligns with the first pillar of BlackRock's IRMP, ex ante risk measurement. This chapter includes a discussion of analytical and empirical durations, partial durations, interest rate scenario analysis, and horizon rate of return analysis. The parametric measures of market risk continue to form the backbone of more elaborate and compressive risk methodologies and techniques, which is why we felt that it was an important chapter to revisit and revise in this edition. This chapter has been updated with more recent data. It also includes additional concepts, such as duration times spread (DxS), authored by David Greenberg, former managing director in Technology & Operations—Artificial Intelligence (AI) Labs. Additionally, we added a new section on option usage in portfolio management, which was authored by Jack Hattem, managing director in the Portfolio Management Group. Yury Krongauz, managing director in the Financial Modeling Group, included additional details regarding wave shocks to the Key Rate Duration section. This chapter was updated by Matthew Wang, managing director in the Fundamental Fixed Income Portfolio Management Group.
Chapter 3 reviews the dynamics of interest rate shocks and was also previously published in the first edition. The concepts in this chapter are also part of the first pillar of BlackRock's IRMP and contain an introduction to principal component analysis as well as an investigation of the probability distribution of interest rate shocks. In this chapter, the relationship between the first principal component and the term structure of volatility is explored and the results are applied to the study of big market move days as well as the historical steepeners and flatteners of the US Treasury curve. This chapter was updated by Matthew Wang.
Chapter 4 focuses on estimating and decomposing portfolio risk and also aligns with the first pillar of BlackRock's IRMP. This chapter reviews portfolio volatility estimation and factor structure, along with the empirical challenges associated with estimating covariance matrices. It contains an overview of Value at Risk (VaR) estimation, including a focus on Enhanced Historical VaR (EHVaR), which is a proprietary approach developed for modeling the forward distribution of asset returns. EHVaR blends the advantages of both parametric and nonparametric forecasting techniques. Finally, the chapter discusses decomposition of realized risk and return. This chapter was coauthored by Amandeep Dhaliwal, managing director in the Financial Modeling Group, along with Tom Booker, director in the Financial Modeling Group.
Chapter 5 introduces the Market‐Driven Scenarios (MDS) framework, which is designed to provide structure to the often subjective and ad hoc nature of hypothetical scenario generation. Macroeconomic fundamentals typically drive the general direction of financial market returns. However, tail risks, which can be triggered by geopolitical events, can arise that are difficult to forecast but can have significant adverse effects on fund returns. As an element of the first pillar, this chapter highlights the use of specific econometric techniques and the application of a disciplined multistep process to create Market‐Driven Scenarios. The MDS process is inherently multi‐asset versus being particularly fixed‐income oriented. This chapter was coauthored by myself, David Greenberg, and Ronald Ratcliffe, managing director in the Analytics & Quantitative Solutions team within BlackRock Solutions.
Chapter 6 uses the MDS framework to analyze geopolitical risks and assess their potential market impact in a systematic way. The chapter reviews market responses to unexpected historical geopolitical shocks from 1962–2019. Using one of the top geopolitical risks from 2019 as an example, this chapter demonstrates the application of the MDS framework. This chapter aligns with the first pillar of the IRMP and reinforces the importance of scenario analysis and stress testing portfolios. It was coauthored by Catherine Kress, director and head of Geopolitical Research & Strategy within the BlackRock Investment Institute; Carl Patchen, former vice president in the Risk & Quantitative Analysis group; Ronald Ratcliffe; Eric Van Nostrand, former managing director in the BlackRock Sustainable Investment group; and Kemin Yang, former associate in the BlackRock Investment Institute. Additional contributors include myself, Tom Donilon, chairman of the BlackRock Investment Institute; and Isabelle Mateos y Lago, global head of BlackRock's Official Institutions group.
Chapter 7 presents some approaches for measuring liquidity risk, one of the many investment risks that demands rigorous and continuous oversight. While liquidity risk can have different meanings, this chapter focuses on fund liquidity risk. As a component of the first pillar, this chapter contains a brief history of how liquidity risk management has evolved and covers the various elements of a liquidity risk management framework, including asset liquidity, redemptions, and extraordinary measures. This chapter was coauthored by myself; Philip Sommer, director in the Liquidity & Trading Research Group within BlackRock Solutions; Stefano Pasquali, head of the Liquidity & Trading Research Group within BlackRock Solutions; Michael Huang, managing director in the Risk & Quantitative Analysis group; Kristen Walters, former managing director in the Risk & Quantitative Analysis group; and Nikki Azznara, vice president in the Portfolio Management Group.
Chapter 8 presents approaches for managing market risk in fixed‐income portfolios using portfolio optimization techniques. An earlier version of this chapter was previously included in the first edition. However, it has been significantly updated and transformed to reflect new approaches for optimization, including many that are also applicable to multi‐asset portfolios. The chapter begins with a discussion of the differences between risk measurements versus risk management and covers typical fixed‐income hedges. Then, the chapter transitions to discuss parametric hedging techniques, generalized approaches to hedging, and advanced portfolio optimization and risk management techniques. Various examples are included in the chapter to demonstrate how optimization approaches can be utilized in different situations. This chapter does not necessarily align uniquely with a specific IRMP pillar. Rather, portfolio optimization is a powerful and versatile tool that allows portfolios to be engineered for a variety of reasons. This chapter was primarily authored by Alex Ulitsky, managing director in the Financial Modeling Group. Jack Hattem provided significant updates to this chapter.
Chapter 9 introduces the second pillar, risk governance, and also introduces the concept of risk scans to identify potential risk issues. Specifically, properly designed risk and exposure scans can flag portfolios and positions that may not align with client objectives or expectations. Given the increasing size and heterogeneity of investment processes and products, risk managers need to efficiently analyze a multitude of portfolios. This chapter presents a basic univariate risk scan framework that uses simple algorithms to identify potential risk exceptions—what came to be known at BlackRock as Risk and Performance Targets (RPT). I was the primary author of this chapter. Rory van Zwanenberg, director in the Risk & Quantitative Analysis group, significantly contributed to this chapter, along with Katie Day, managing director in the Risk & Quantitative Analysis group.
The third pillar, portfolio manager risk-return awareness, focuses on the relationship between portfolio and risk managers. Chapter 10 discusses the importance of risk managers working together with portfolio managers to ensure that risks are properly detected, understood, and then appropriately managed for clients. Effective risk management requires regular interaction with portfolio managers to discuss risk positioning and can include identifying potential adverse behavioral aspects of investing. The chapter concentrates on behavioral finance, an evolving risk management domain, which seeks to identify cognitive blind spots that can impact investment decisions. The chapter includes details on decision‐making analytics such as loss aversion, disposition bias, and the endowment effect. The chapter also includes a framework for evaluating behavioral aspects of the investment processes. This chapter was coauthored by Emily Haisley, managing director of the behavioral finance initiatives in the Risk & Quantitative Analysis group, and Nicky Lai, director in the Risk & Quantitative Analysis group.
The fourth pillar, performance attribution, decomposes investment returns into their sources of performance, providing portfolio and risk managers with an understanding of the drivers of investment results. Chapter 11 covers approaches and analytical techniques that practitioners can leverage to conduct performance attribution, including Brinson and factor‐based methodologies. The chapter provides multiple examples to demonstrate how portfolio returns can be viewed and interpreted. This chapter was coauthored by Reade Ryan, managing director in the Risk & Quantitative Analysis group, and Carol Yu, former vice president in the Risk & Quantitative Analysis group.
The fifth pillar, performance analysis, presents a framework to review a portfolio's realized performance relative to its benchmarks, peers, and other comparable accounts. Chapter 12 discusses how to meaningfully measure aggregate platform performance, especially across a heterogeneous set of funds with different benchmarks and risk and performance targets. The chapter covers active performance metrics, such as alpha target ratio, weighted peer percentile, and alpha dollars, along with index performance metrics. Strengths and weaknesses of the various active and index performance measurements are presented. This chapter was coauthored by Mark Paltrowitz, managing director and chief performance officer for BlackRock and the head of fixed‐income and multi‐asset investment risk; Mark Temple‐Jones, former director in the ETF & Index Investments group; Viola Dunne, former managing director in the Risk & Quantitative Analysis group; and Christopher Calingo, director in the Risk & Quantitative Analysis group.
Chapter 13 marks the conclusion of the first section of this book and discusses further evolving the Investment Risk Management Paradigm. Given the dynamic nature of financial risk, continuously evolving a risk management framework to address emerging risks and changing market themes is crucial for a growing investment manager. This chapter starts by covering the characteristics of a traditional buy‐side risk management framework and then discusses evolving the framework to better manage a multiplicity of risks at scale. BlackRock Solutions' Aladdin implementation of the Risk Radar system is presented as a tangible example of how risk governance can be successfully executed at scale. This chapter was coauthored by myself; Michael Huang; and Joe Buehlmeyer, director in the Aladdin Product Group.
Despite rapid transformation in other areas of financial markets, for decades, the core transactional underpinnings of bond markets remained largely the same—high touch, over‐the‐counter markets dependent on dealers' balance sheets with only limited timely price, volume, and order book transparency. However, in the years following the 2008 Global Financial Crisis, significant structural changes in bond markets have occurred. This section briefly discusses some of those bond market changes over the past 20 years.
Chapter 14 discusses the modernization of the bond market and the emergence of fixed‐income exchange‐traded fund products. The chapter covers the evolution of bond markets, the development of index‐based ecosystems, the implications for investing, portfolio management and risk management, and the future state of portfolio construction. This chapter was coauthored by Daniel Veiner, managing director, co‐head of Global Trading; Stephen Laipply, managing director, global co-head of Fixed Income ETFs; Carolyn Weinberg, managing director, chief product innovation officer and co‐head of the Global Product Group; Samara Cohen, senior managing director, chief investment officer of ETF and Index Investments; Vasiliki Pachatouridi, managing director, head of iShares Fixed Income Product Strategy EMEA; and Hui Sien Koay, director, lead Index Fixed Income Product Strategist for APAC.
Chapter 15 discusses the cessation of LIBOR and the massive undertaking required to shift to Alternative Reference Rates (ARRs). Given the transition's size and scope, the migration away from LIBOR required a significant amount of coordination and organization from various market participants. This chapter also discusses the implications to portfolio management along with risk management. This chapter was written by Jack Hattem.
Chapter 16 covers derivatives reform and the rise of Swap Execution Facilities (SEFs) and central counterparties (CCPs). Following the Global Financial Crisis, market reforms sought to improve transparency in derivatives. Electronification of most trading was required, and counterparty credit risk was reduced by mandating much greater usage of CCPs. This chapter was written by Eileen Kiely, managing director and deputy head of Counterparty Risk in the Risk & Quantitative Analysis group, and Jack Hattem.
Major market disruptions, almost by definition, present the opportunity (and need) to reflect on the necessary changes to risk management practices. The following three chapters were previously published articles that identify some lessons to be learned.
Chapter 17 presents seven specific lessons worth remembering from the Global Financial Crisis of 2007–2008. The credit crisis demonstrated that many widely used risk management techniques relied on critical assumptions that turned out to be profoundly flawed. The Global Financial Crisis changed the risk management profession, with unprecedented extreme market moves and the downfall of well‐known financial institutions. Recommendations to enhance risk management practices and beliefs are included in this chapter to correct or mitigate the negative impact of relying on those faulty assumptions.
Chapter 18 highlights the importance of eight principles for buy‐side risk management. Chapter 17 and Chapter 18 were initially published in the Journal of Portfolio Management and coauthored by myself and Conan Crum, former vice president in the Risk & Quantitative Analysis group.
Finally, the book concludes with a chapter on lessons worth considering from the Coronavirus pandemic. Chapter 19 summarizes 10 key lessons from COVID‐19 and considers the implications of the COVID‐19 crisis across capital markets. This chapter reviews the key market events from March 2020 and the official sector's interventions. The chapter includes some lessons drawn from COVID‐19, identifying what worked and what needs to be addressed further, including policy recommendations and areas for future consideration. This chapter was originally published as a BlackRock ViewPoint and was adapted for this book by coauthors Barbara Novick, a co-founder and former vice chairman of BlackRock; Joanna Cound, managing director and global head of Public Policy; Kate Fulton, managing director and head of Americas Public Policy; and Winnie Pun, former managing director within the Global Public Policy group.
BlackRock's Guide to Fixed-Income Risk Management is written for financial services professionals, including chief investment officers, portfolio managers, risk managers, traders, researchers, compliance officers, and modelers. Using BlackRock's approach to risk management as its foundation, the book is particularly intended for buy‐side firms. It is also suitable in an academic setting for undergraduate students as well as MBA and PhD candidates.

Several current and former BlackRock subject matter experts authored or coauthored multiple chapters in this book. Their names are listed in the following section and their current (or last) BlackRock titles and team affiliations are provided the first time their names appear. For current BlackRock employees, their titles and team affiliations are representative of their roles as of March 2023.
The challenge of measuring and managing the risk of thousands of complex and diverse fixed‐income portfolios during periods of both calm and extremely stressed markets offers the ideal setting for developing and applying new ideas. For 34 years, I was fortunate to work in precisely such an environment at BlackRock, Inc., a premier global asset management and risk advisory firm, which served as a state‐of‐the‐practice “laboratory.” That laboratory grew in assets under management (AUM) massively during my tenure there, along the dimensions of new products, new asset classes, and new geographies. This environment provided a never‐ending and extremely focused demand for practical solutions to real‐life problems. Fortunately, because of sophisticated, knowledgeable, and experienced colleagues, who were never shy about providing critiques and feedback, creative and innovative solutions to many risk management challenges developed naturally. The very nature of the problems faced by risk managers—forecasting and mitigating potential severe financial losses—creates the sense of urgency needed to get things done.
BlackRock's risk management philosophy is embedded in the firm's culture and requires the constant development, enhancement, and validation of rigorous techniques for risk measurement and management. Since inception, the firm's commitment to technology and analytics has led to a significant amount of resources being made available for risk management. At the same time, BlackRock's disciplined investment styles and diversity of investment products and services, ranging from mutual funds and institutional accounts to hedge funds, real estate investments trusts (REITs), and collateralized loan obligations (CLOs), created demand for methodologies that are theoretically sound, accurate, intuitive, and computationally feasible. On the other hand, the collaborative approach to portfolio and risk management has led to empirical validation and enhancement of models through constant interaction among financial modelers, portfolio managers, traders, and analysts. This provided a unique opportunity for reconciling theory with reality. Simply put, nothing makes a risk manager's mind focus better than being 20 feet away from a fixed‐income trading desk!
The conceptual and computational challenges of risk measurement and management increase exponentially with the size of a financial institution and the diversity of asset classes in which it invests. BlackRock was founded in 1988 as a niche fixed‐income investment firm. Since then, it has transformed itself into a global investment company with over $9 trillion of AUM1 and independently provides a wide range of risk management services to third‐parties. This rapid growth created unique challenges. It was not only critical to develop risk management methodologies universally pertinent to (almost) all classes of fixed‐income securities, portfolios, and benchmarks, but to ensure that these approaches were suitable for large‐scale practical application in a computationally and operationally feasible manner.
It goes almost without saying that the BlackRock that served as a hothouse for risk management innovations would not have existed as we know it without the leadership provided by Larry Fink and Rob Kapito. Risk management does not have much value if no risks are being taken. Larry, BlackRock's “fearless leader,” and Rob provided much of the boldness that, in retrospect, seemed so obvious. Rob Goldstein and Derek Stein kept the shop running, defying the challenges of scale, and Barbara Novick worked hard to keep BlackRock out of political and regulatory troubles.
This book builds on the concepts that were published in the first edition and introduces new methodologies and topics. This book represents the thought leadership, research, and analysis of many BlackRock risk managers, portfolio managers, traders, financial modelers, and other subject matter experts who have helped to advance the field.
No list of acknowledgments would be complete without singling out my colleague and friend, Ed Fishwick. Ed was my partner co‐managing BlackRock's Risk & Quantitative Analysis group starting when BlackRock acquired Merrill Lynch Investment Management in 2006. For almost 16 years, we worked together very closely, evolving BlackRock's risk management processes and procedures to ever‐changing circumstances. Ed is a world‐renowned expert in all matters relating to equity and multi‐asset risk management. Yet, this fixed‐income‐oriented book benefited greatly from his insights and wisdom.
I want to recognize the contribution of my former colleague and friend, Charlie Hallac, who was taken from us before his time, for his extraordinary ability to turn many of the ideas presented in this book into practical reality through robust implementation and infrastructure. Absent his efforts, much that was achieved would have only been academic.
