In this Paper we evaluate (return based) style analysis. The portfolio and positivity constraints imposed by style analysis are useful in constructing mimicking factor portfolios without short positions. We use a simple simulation experiment to show that imposing these constraints in estimating...

Copulas offer financial risk managers a powerful tool to model the dependence between the different elements of a portfolio and are preferable to the traditional, correlation-based approach. In this paper we show the importance of selecting an accurate copula for risk management. We extend...
