Dynamic Portfolio Optimization with a Defaultable Security and Regime‐Switching

A Capponi, JE Figueroa‐López - Mathematical Finance, 2014 - Wiley Online Library
We consider a portfolio optimization problem in a defaultable market with finitely‐many
economical regimes, where the investor can dynamically allocate her wealth among a …

[HTML][HTML] European option pricing with market frictions, regime switches and model uncertainty

TK Siu - Insurance: Mathematics and Economics, 2023 - Elsevier
The impact of market frictional costs on pricing insurance and financial products in a regime-
switching environment has not been well-explored. This paper introduces a general pricing …

Pricing European Vulnerable Options with Jumps and Stochastic Default Obstacles Barrier under Regime Switching

X Liu, Z Zhang - Mathematics, 2023 - mdpi.com
In this paper, we propose an enhanced model for pricing vulnerable options. Specifically,
our model assumes that parameters such as interest rates, jump intensity, and asset value …

Detecting stock market regimes from option prices

WN Lai - Operations Research Letters, 2022 - Elsevier
Equity market returns alternate between periods of calm and crises. Researchers commonly
employ regime switching models to capture this behaviour. We show that forward-looking …

Hedging options in a doubly Markov-modulated financial market via stochastic flows

TK Siu, RJ Elliott - International Journal of Theoretical and Applied …, 2019 - World Scientific
The hedging of a European-style contingent claim is studied in a continuous-time doubly
Markov-modulated financial market, where the interest rate of a bond is modulated by an …

Risk sensitive portfolio optimization with default contagion and regime-switching

L Bo, H Liao, X Yu - SIAM Journal on Control and Optimization, 2019 - SIAM
We study an open problem of risk-sensitive portfolio allocation in a regime-switching credit
market with default contagion. The state space of the Markovian regime-switching process is …

Optimal portfolio in a regime-switching model

ARL Valdez, T Vargiolu - Seminar on Stochastic Analysis, Random Fields …, 2013 - Springer
In this paper we derive the solution of the classical Merton problem, ie, maximizing the utility
of the terminal wealth, in the case when the risky assets follow a diffusion model with …

Optimal investment of variance-swaps in jump-diffusion market with regime-switching

L Bo, D Tang, Y Wang - Journal of Economic Dynamics and Control, 2017 - Elsevier
We consider a general jump-diffusion market with regime-switching where the jump risk is
modeled as a Markov-modulated Poisson random measure. In this incomplete market, we …

Optimal credit investment and risk control for an insurer with regime-switching

L Bo, H Liao, Y Wang - Mathematics and Financial Economics, 2019 - Springer
This paper studies an optimal investment and risk control problem for an insurer with default
contagion and regime-switching. The insurer in our model allocates his/her wealth across …

Portfolio optimization in a defaultable Lévy-driven market model

S Pagliarani, T Vargiolu - OR spectrum, 2015 - Springer
In this paper, we analyse a market where the risky assets follow defaultable exponential
additive processes, with coefficients depending on the default state of the assets. In this …
