Application of multistage stochastic programs solved in parallel in portfolio management

چکیده
We present a multistage model for allocation of financial resources to bond indices in different currencies. The model was tested on historical data of interest and exchange rates. We compare a two-stage and a three-stage stochastic programming model from a financial performance point of view. For solving two-stage and three-stage stochastic programs the interior point method (IPM) in the frame of the primal-dual path following formulation is used. An application of the Birge and Qi factorization to the IPM allows decomposition of large linear system to smaller blocks allowing thus to solve it in parallel. The parallel code is written in the Fortran programming language, using the Message Passing Interface (MPI) for communication. Parallel and financial performance is illustrated on experiments executed on the IBM 1350 Linux cluster.

A Defined Benefit Pension Fund ALM Model through Multistage Stochastic Programming
We consider an asset-liability management (ALM) problem for a defined benefit pension fund (PF). The PF manager is assumed to follow a maximal fund valuation problem facing an extended set of risk factors: due to the longevity of the PF members, the inflation affecting salaries in real terms and future incomes, interest rates and market factors affecting jointly the PF liability and asset p...
متن کاملMultistage stochastic portfolio optimisation in deregulated electricity markets using linear decision rules
The deregulation of electricity markets increases the financial risk faced by retailers who procure electric energy on the spot market to meet their customers’ electricity demand. To hedge against this exposure, retailers often hold a portfolio of electricity derivative contracts. In this paper, we propose a multistage stochastic mean-variance optimisation model for the management of such a por...
متن کاملScenario tree modelling for multistage stochastic programs
An important issue for solving multistage stochastic programs consists in the approximate representation of the (multivariate) stochastic input process in the form of a scenario tree. In this paper, forward and backward approaches are developed for generating scenario trees out of an initial fan of individual scenarios. Both approaches are motivated by the recent stability result in [15] for op...
متن کاملScenario tree modeling for multistage stochastic programs
An important issue for solving multistage stochastic programs consists in the approximate representation of the (multivariate) stochastic input process in the form of a scenario tree. In this paper, we develop (stability) theory-based heuristics for generating scenario trees out of an initial set of scenarios. They are based on forward or backward algorithms for tree generation consisting of re...
متن کاملOptimal Multistage Portfolio Management Using a Parallel
We present a multi-stage model for allocation of financial resources to different currencies. The model is tested using a three-stage scenario tree with a mean-reversion property. For solving three-stage stochastic programs the interior point method (IPM) in the frame of the primal-dual path-following formulation is used. Because the matrix of the corresponding linear system is large, sparse an...
