Prediction Revisited: The Importance of Observation (2022)

A thought-provoking and startlingly insightful reworking of the science of prediction

In Prediction Revisited: The Importance of Observation, our team delivers a ground-breaking reassessment of the delicate science of prediction for anyone who relies on data to contemplate the future. The book reveals why standard approaches to prediction based on classical statistics fail to address the complexities of social dynamics, and it provides an alternative method based on the intuitive notion of relevance.

We describe, both conceptually and with mathematical precision, how relevance plays a central role in forming predictions from observed experience. Moreover, we propose a new and more nuanced measure of a prediction’s reliability. Prediction Revisited also offers:

  • Clarifications of commonly accepted but less commonly understood notions of statistics

  • Insight into the efficacy of traditional prediction models in a variety of fields

  • Colorful biographical sketches of some of the key prediction scientists throughout history

  • Mutually supporting conceptual and mathematical descriptions of the key insights and methods discussed within

With its strikingly fresh perspective grounded in scientific rigor, Prediction Revisited is sure to earn its place as an indispensable resource for data scientists, researchers, investors, and anyone else who aspires to predict the future from the data-driven lessons of the past.

Asset Allocation: From Theory to Practice and Beyond (2021)

In Asset Allocation: From Theory to Practice and Beyond—the newly and substantially revised Second Edition of A Practitioner’s Guide to Asset Allocation—accomplished finance professionals William Kinlaw, Mark P. Kritzman, and David Turkington deliver a robust and insightful exploration of the core tenets of asset allocation.

Drawing on their experience working with hundreds of the world’s largest and most sophisticated investors, the authors review foundational concepts, debunk fallacies, and address cutting-edge themes like factor investing and scenario analysis. The new edition also includes references to related topics at the end of each chapter and a summary of key takeaways to help readers rapidly locate material of interest.

A Practitioner's Guide to Asset Allocation (2017)

A Practitioner's Guide to Asset Allocation also explores the innovations that address key challenges to asset allocation and presents an alternative optimization procedure to address the idea that some investors have complex preferences and returns may not be elliptically distributed. Among the challenges highlighted, the authors explain how to overcome inefficiencies that result from constraints by expanding the optimization objective function to incorporate absolute and relative goals simultaneously. The text also explores the challenge of currency risk, describes how to use shadow assets and liabilities to unify liquidity with expected return and risk, and shows how to evaluate alternative asset mixes by assessing exposure to loss throughout the investment horizon based on regime-dependent risk. This practical text contains an illustrative example of asset allocation which is used to demonstrate the impact of the innovations described throughout the book.

The Portable Financial Analyst (2007)

Financial professionals are faced with increasingly technical topics that are theoretically complicated but practically necessary in determining the trade-off between risk and return. The Portable Financial Analyst, Second Edition is a unique collection of essays that address the heart of every analyst's and investor's dilemma: how to make decisions in the face of unknown forces and how to assert some control over the outcome

Puzzles of Finance (2000)

Puzzles of Finance takes on today's most persistently challenging financial questions and, through clever examples and just plain logic, helps you move beyond those questions to arrive at a deeper understanding of finance and the daily management of money. From Siegel's Paradox ("Is it possible to profit from asymmetry of exchange rate changes?") to questions of option value ("Why is the value of an option unaffected by the underlying asset's expected return?"), Puzzles of Finance goes beyond vague theoretical suppositions to supply practical, concrete solutions that investors and money managers can benefit from every day. While the intellectually curious will be drawn to Puzzles of Finance, it is the day-to-day finance professional who will derive the most benefit from this remarkable book.
