What Drives Bond Yields?
July 26, 2021
In this overview of the various factors that influence government bond yields, we show that both in theory and in the data, non-monetary policy factors drive significant variation in yields, particularly at longer maturities. Despite the exceptionally low yield environments we have witnessed, fundamentals continue to drive bond markets.

2021 Capital Market Assumptions for Major Asset Classes
Q1 2021
We update our estimates of medium-term (5- to 10-year) expected returns for major asset classes. We also discuss what investors should expect from the stock-bond correlation in the coming decade.

Fire and Ice: Confronting the Twin Perils of Inflation and Deflation
Q4 2020
The COVID-19 pandemic and the responses to it by governments, central banks and consumers have unleashed both disinflationary and inflationary forces, but we do not know which forces will win over the longer term. We explore the historical inflation sensitivities of a range of different investments and present the benefits of both risk-balanced asset allocations and dynamic directional strategies to prepare for uncertain times.

It’s Not a Bound; It’s an Opinion
November 20, 2020
In the second paper of our “Bonds Today” series, we review the popular belief that bond yields are too close to zero to fall much further and then explain why we disagree.

Don’t Hate the Asset; Hate the Constraint
November 20, 2020
What role do bonds play in a portfolio today? We explain why it all depends on investors’ ability to own them in a capital efficient way.

Was That Intentional? Ways to Improve Your Active Risk
September 28, 2020
Investors try to outperform their strategic asset allocation benchmarks by taking active risks. Some of these are intentional, but others are low-conviction or even unintentional, which can be a large part of a portfolio’s total active risk. When it comes to beating a strategic asset allocation benchmark, reducing these unintentional active risks may among the clearest sources of “low hanging fruit”.
Working Paper
Principal Portfolios
July 7, 2020
We propose a new asset-pricing framework in which all securities’ signals are used to predict each individual return. While the literature focuses on each security’s own- signal predictability, assuming an equal strength across securities, our framework is flexible and includes cross-predictability.

Biases in Long-Horizon Predictive Regressions
June 4, 2020
This paper derives the small sample bias of estimators in J horizon predictive regressions, providing a plug-in adjustment for these estimators. A number of surprising results emerge, including a higher bias for overlapping than nonoverlapping regressions despite the greater number of observations and particularly higher bias for an alternative long-horizon predictive regression commonly advocated for in the literature.

2020 Capital Market Assumptions for Major Asset Classes (Supplemental Estimates as of March 31, 2020)
May 6, 2020
This supplement provides a special update to our estimates of medium-term (5- to 10-year) expected returns for major asset classes. This update reflects the large changes in prices for many asset classes due to the impact of COVID-19 in Q1 2020.

Enhanced Portfolio Optimization
March 2, 2020
We show how to identify the portfolios that cause problems in standard mean-variance optimization (MVO) and develop an enhanced portfolio optimization (EPO) method that addresses the problems. Applying EPO on several realistic datasets, we find significant gains relative to standard benchmarks.
