In answer to the demand for more sophisticated portfolio strategies, Daniel Giamouridis , Associate Professor in the Department of Accounting and Finance at the Athens University of Economics and Business , and his co-authors from Citigroup have developed an innovative model for factor weighting that uses decision-tree analysis and a comprehensive view of factor risk to improve the reward-to-risk ratio for multifactor investors.In a discussion with Institutional Investor Journals , Giamouridis explains how this model improves dynamic multifactor predictability, thus improving potential portfolio alpha for active equity managers.
