A Fourier approach to the computation of conditional value-at-risk and optimized certainty equivalents
We consider the class of risk measures associated with optimized certainty equivalents.
Capital allocation principles are used in various contexts in which the risk capital or the cost of an aggregate position has to be allocated between its constituent parts.
The presence of options in a portfolio fundamentally alters the portfolio's risk and return profiles when compared with an all-equity portfolio. In this paper, we advocate modeling a risk-based criterion for optioned portfolio selection and rebalancing...
