We use the Shiller CAPE Model proposed by Mebane Faber as a template for the exploration of a variety of portfolio optimization methods. By virtue of the Model's systematic allocation to the 'cheapest' markets with the highest theoretical risk premia, the model has the potential to extract high...

Retirees face longevity risk, or the risk of living longer (or less long) than expected; market risk, or the risk of poor investment returns over the retirement horizon, and finally; failure risk, or the risk of running out of money before death. The authors examine the sensitivity of these three...

The paper addresses flaws in the traditional application of Modern Portfolio Theory related to Strategic Asset Allocation. Estimates of parameters for portfolio optimization based on long-term observed average values are shown to be inferior to alternative estimates based on observations over...

Mean-Variance Optimization (MVO) as introduced by Markowitz (1952) is often presented as an elegant but impractical theory. MVO is "an unstable and error-maximizing" procedure (Michaud 1989), and "is nearly always beaten by simple 1/N portfolios" (DeMiguel, 2007). And to quote Ang (2014):...

Information on the uncertainty of quantitative results feeding into public decision making is essential for designing robust policies. However, this information is often not available in relation to the economics of greenhouse gas (GHG) mitigation in agriculture. This paper analyses the...

This paper follows Keller (2012), which introduced the Flexible Asset Allocation (FAA) concept. FAA is based on a weighted ranking score of historical asset returns (R), volatilities (V), and correlations to an equal weighted index (C). We call this “generalized momentum” since we assume...
