  1. 1. Copula approach to fitting bivariate time series

    Master-uppsats, Lunds universitet/Matematisk statistik

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

    Sammanfattning : 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. LÄS MER

  2. 2. A short bit on copulas and alternative versions of Spearmans rho

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Filip Carlsson; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : This thesis aims to understand copula theory and its application in measuring dependence, particularly in the context of the paper "Multivariate conditional versions of Spearman’s rho and related measures of tail dependence" by Schmid and Schmidt. We clarify certain statements and formulas in Schmid and Schmidt's work, explore the potential of the conditional version of Spearman's rho, and demonstrate empirical versions of copulas and Spearman's rho using a bivariate normal distribution.

  3. 3. Simulation-Based Portfolio Optimization with Coherent Distortion Risk Measures

    Master-uppsats, KTH/Matematisk statistik

    Författare :Andreas Prastorfer; [2020]
    Nyckelord :Risk Management; Portfolio Optimization; Conditional Value-at-Risk; Coherent Distortion Riks Measures; Elliptical Distribution; GARCH model; Normal Copulas; Extreme Value Theory; Risk Contributions; Riskhantering; Portföljoptimering; Conditional Value-at-Risk; Koherenta distortionsriskmått; Elliptiska fördelningar; GARCH modeller; Normal-copula; Extremvärdes teori; Riskbidrag;

    Sammanfattning : This master's thesis studies portfolio optimization using linear programming algorithms. The contribution of this thesis is an extension of the convex framework for portfolio optimization with Conditional Value-at-Risk, introduced by Rockafeller and Uryasev. LÄS MER

  4. 4. Quantitative Portfolio Construction Using Stochastic Programming

    Master-uppsats, KTH/Matematisk statistik

    Författare :Aidin Ashant; Elisabeth Hakim; [2018]
    Nyckelord :Asset Allocation; Dynamic Portfolio Construction; Stochastic Programming; Scenario Generation; Multivariate GARCH; DCC-GARCH; Copula-GARCH; Transaction Costs; Mean-Absolute Deviation; Risk Parity; Mean-Variance; Tillgångsallokering; Dynamisk Portfölj Konstruktion; Stokastisk Programmering; Scenario Generation; Multivariat GARCH; DCC-GARCH; Copula- GARCH; Transaktionskostnader; Mean-Absolute Deviation; Risk Parity; Mean-Variance;

    Sammanfattning : In this study within quantitative portfolio optimization, stochastic programming is investigated as an investment decision tool. This research takes the direction of scenario based Mean-Absolute Deviation and is compared with the traditional Mean-Variance model and widely used Risk Parity portfolio. LÄS MER

  5. 5. The Performance of Market Risk Models for Value at Risk and Expected Shortfall Backtesting : In the Light of the Fundamental Review of the Trading Book

    Master-uppsats, KTH/Matematisk statistik

    Författare :Katja Dalne; [2017]
    Nyckelord :Risk Management; Financial Time Series; Value at Risk; Expected Shortfall; Monte Carlo Simulation; GARCH modeling; Copulas; Hybrid Distribution; Generalized Pareto Distribution; Extreme Value Theory; Backtesting; Liquidity Horizon; Basel regulation.;

    Sammanfattning : The global financial crisis that took off in 2007 gave rise to several adjustments of the risk regulation for banks. An extensive adjustment, that is to be implemented in 2019, is the Fundamental Review of the Trading Book (FRTB). LÄS MER
