  1. 1. Pricing and Modeling Heavy Tailed Reinsurance Treaties - A Pricing Application to Risk XL Contracts

    University essay from KTH/Matematisk statistik

    Author : Ormia Abdullah Mohamad; Anna Westin; [2023]
    Keywords : Reinsurance; Extreme Value Theory; POT-model; Hill estimator; Risk XL contracts; Generalized Pareto distribution; Method of Moments.; Återförsäkring; Extremevärdesteori; POT-modellen; Hill estimatorn; Risk XL kontrakt; generella Paretofördelningen; Momentmetoden.;

    Abstract : To estimate the risk of a loss occurring for insurance takers is a difficult task in the insurance industry. It is an even more difficult task to price the risk for reinsurance companies which insures the primary insurers. READ MORE

  3. 2. Forecasting Value-at-Risk and Expected Shortfall: A comparison of non- and parametric methods for crude oil amidst extreme volatility

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Otto Colbin; Yugam Sharma; [2023]
    Keywords : Value-at-Risk VaR ; Expected Shortfall ES ; Nonparametric estimation methods; Parametric estimation methods; Crude oil.; Business and Economics;

    Abstract : Practitioners primarily utilise nonparametric methods when estimating Value-at- Risk (VaR) and Expected Shortfall (ES) for computing capital requirements. However, various researchers assert that there are issues with those estimates, particularly amidst periods of market turmoil. READ MORE

  4. 3. Copula approach to fitting bivariate time series

    University essay from Lunds universitet/Matematisk statistik

    Author : Jun Wang; [2023]
    Keywords : VaR; Copula; ARMA-GARCH; Extreme Value Theory; GPD; Hill estimator; Mathematics and Statistics;

    Abstract : We apply the GARCH-copula method to estimate Value at Risk (VaR) for European and Stockholm stock indices. First, marginal distributions are estimated by the ARMA-GARCH model with normal, Student-t, and skewed t distributions. READ MORE

  5. 4. Generating Extreme Value Distributions in Finance using Generative Adversarial Networks

    University essay from KTH/Matematik (Avd.)

    Author : William Nord-Nilsson; [2023]
    Keywords : Extreme Value Theory; Generative Adversarial Networks; Stress Testing; Machine Learning; Convolutional Neural Networks; evtGAN; Extreme Events; Extremvärdesteori; Generativa nätverk; Stresstestning; Maskininlärning; Djupt neuralt nätverk; evtGAN; Extrema händelser;

    Abstract : This thesis aims to develop a new model for stress-testing financial portfolios using Extreme Value Theory (EVT) and General Adversarial Networks (GANs). The current practice of risk management relies on mathematical or historical models, such as Value-at-Risk and expected shortfall. READ MORE

  6. 5. Risk Assessment of International Mixed Asset Portfolio with Vine Copulas

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Axel Nilsson; [2022]
    Keywords : Vine Copulas; Extreme Value Theory; Financial Risk Management; Vine Copulas; Extremvärdesteori; Finansiell riskhantering;

    Abstract : This thesis gives an example of assessing the risk of a financial portfolio with international assets, where the assets may be of different classes, by the use of Monte Carlo simulation and Extreme Value Theory. The simulation uses univariate modelling, models of the assets’ returns as stochastic processes, as well as vine copulas to create dependency between the variables. READ MORE
