Using a parametric portfolio optimization approach, I show how international momentum strategies can be significantly improved by decomposing global momentum returns. The parametrization models the optimal portfolio weights as a function of the decomposed components and overweights equity...

In this paper, we study the effectiveness of carry trade strategies during and after the financial crisis using a flexible approach to modeling currency returns. We decompose the currency returns into multiplicative sign and absolute return components, which exhibit much greater predictability...

This paper investigates the factors that affect the covariance between the federal funds rate and stock returns. I estimate a VAR system and implement covariance decomposition analysis. Most of the covariance between the federal funds rate and stock returns is affected by changes in stock market...
