Mind the Cap! -- Constrained Portfolio Optimisation in Heston's Stochastic Volatility Model

no code implementations19 Jun 2023 Marcos Escobar-Anel, Michel Kschonnek, Rudi Zagst

We consider a portfolio optimisation problem for a utility-maximising investor who faces convex constraints on his portfolio allocation in Heston's stochastic volatility model.

Portfolio Optimization with Allocation Constraints and Stochastic Factor Market Dynamics

no code implementations17 Mar 2023 Marcos Escobar-Anel, Michel Kschonnek, Rudi Zagst

Using this representation, we provide a condition on the market dynamics and the allocation constraints, which ensures that the solution to the HJB PDE is exponentially affine and separable.

Value-at-Risk constrained portfolios in incomplete markets: a dynamic programming approach to Heston's model

no code implementations30 Aug 2022 Marcos Escobar-Anel, Yevhen Havrylenko, Rudi Zagst

Via the same financial derivative, the optimal wealth and the optimal investment strategy in the constrained problem are linked to the optimal wealth and the optimal investment strategy in the unconstrained problem.

Risk sharing in equity-linked insurance products: Stackelberg equilibrium between an insurer and a reinsurer

no code implementations8 Mar 2022 Yevhen Havrylenko, Maria Hinken, Rudi Zagst

The reinsurer is the leader in the game and maximizes its expected utility by selecting its optimal investment strategy and a safety loading in the reinsurance contract it offers to the insurer.

Decrease of capital guarantees in life insurance products: can reinsurance stop it?

no code implementations5 Nov 2021 Marcos Escobar-Anel, Yevhen Havrylenko, Michel Kschonnek, Rudi Zagst

We analyze the potential of reinsurance for reversing the current trend of decreasing capital guarantees in life insurance products.

Closed-form portfolio optimization under GARCH models

no code implementations1 Sep 2021 Marcos Escobar-Anel, Maximilian Gollart, Rudi Zagst

This paper develops the first closed-form optimal portfolio allocation formula for a spot asset whose variance follows a GARCH(1, 1) process.

Optimal life-cycle consumption and investment decisions under age-dependent risk preferences

no code implementations27 Aug 2019 Andreas Lichtenstern, Pavel V. Shevchenko, Rudi Zagst

In this article we solve the problem of maximizing the expected utility of future consumption and terminal wealth to determine the optimal pension or life-cycle fund strategy for a cohort of pension fund investors.
