The authors of this article, Nicolas Firzli, WPC, David Weeks, AMNT, and the Hon. Nick Sherry, SEF, co-chaired the main financial roundtable during the COP21/Paris Agreement conference: the Paris Climate Finance Roundtable (CFR) , alongside Dr. Jeffrey Sachs, Director, Center for Sustainable...

Extended examples of long-term, annually rebalanced portfolio performance using the modified risk parity (MRP) approach are presented. The analysis considers three distinct diversified portfolio holdings, comprising index funds, sector funds and a blended portfolio of index and sector funds.The...

We examine the relation between households’ wealth and relative risk aversion (RRA) in two different frameworks: the Behavioral Portfolio Theory (BPT) and Merton’s consumption and portfolio choice model (CPCM). We apply the BPT to field data for the first time and show that the BPT provides...

I derive two valid forecasting models of the equity premium in monthly frequency, based on little more than no-arbitrage: A "predictability timing" version of partial least squares, given that predictability is theoretically time-varying; and a least squares model with realized market premiums...

Motivated by the recent rise of populism in western democracies, we develop a tractable equilibrium model in which a populist backlash emerges endogenously in a strong economy. In the model, voters dislike inequality, especially the high consumption of ``elites." Economic growth exacerbates...

We propose target date funds modified to exploit stock return predictability driven by the variance risk premium. The portfolio rule of these tactical target date funds (TTDFs) is extremely simplified relative to the optimal one, making it easy to implement and communicate to investors. We show...

We show that a new measure of buy-side competition explains momentum profits. The momentum quintile spread is 1.11% when competition is low and negligible when competition is high. Better alphas are attained with superior Sharpe and Sortino ratios, no negative skewness and in more investible...

The prudent investor rule, enacted in every state over the last 30 years, is the centerpiece of trust investment law. Repudiating the prior law’s emphasis on avoiding risk, the rule reorients trust investment toward risk management in accordance with modern portfolio theory. The rule directs a...

Machine Learning algorithms have been widely used and proven effective in financial markets. In this paper, we introduced a Machine Learning model set trained on the residual factors from the Fama-French three-factor model (Fama and French, 1992) to find significant alpha factors. To include...

Investors have access to a multitude of personalized indexing products, a key benefit of which is to allow for tax-loss harvesting (TLH). Using a simple example, we demonstrate many features of TLH and establish an invariance result which highlights circumstances where TLH does not matter. Using...
