Abstract:
We consider here several interrelated optimization models for portfolio selection and risk management which can be broadly classified as belonging to stochastic optimization models. In particular we consider
- Selection of VaR-optimal portfolios where we design numerical approach and software tools for computing mean-Value-at-Risk efficient portfolios starting from historic data. The underlying theory is presented together with the results of extensive in-sample and out of sample experiments with the data sets of interest to institutional investor.
- Risk budgeting models where investor faces the problem of portfolio selection from a set of financial instruments which are exposed to partially commeasurable risks. The typical example is budgeting of risk exposure between passive and active portfolio management strategies.
We show that the modern stochastic optimization methodology provides efficient solutions to risk management problems in context of portfolio selection.
