This paper explores a linear hedge fund replication and alternative beta methodology that is robust to the presence of non linearities and the possibility of model mis-specification. In a fashion similar to Roncalli and Weisang (2009a), the problem is cast as a tracking problem in order to allow...

While the use of dynamic factor models for Hedge Fund Replication (HFR) has proven to be superior to standard OLS methodologies (e.g., Roncalli and Weisang, 2009a,b), current factor selection methodology in these dynamic settings by means of direct PCA-based estimation of the factors (e.g.,...

Portfolio construction and risk budgeting are the focus of many studies by academics and practitioners. In particular, diversification has spawn much interest and has been defined very differently. In this paper, we analyze a method to achieve portfolio diversification based on the decomposition...
