  1. 1. Extremvärdesanalys och VaR : En metod för finansiell riskberäkning

    Kandidat-uppsats, Uppsala universitet/Matematiska institutionen

    Författare :Mattis Rosengren; [2023]
    Nyckelord :Extremvärdesanalys; statistik; VaR;

    Sammanfattning : Riskanalys handlar i stora drag om att studera förekomsten och konsekvenserna av särskilda händelser. Av särskild vikt är de så kallade \emph{extrema} händelserna; de som sällan inträffar, men medför påtagliga konsekvenser när det väl sker. LÄS MER

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

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

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

    Sammanfattning : 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. LÄS MER

  4. 3. Into the Trading Book: Estimating Expected Shortfall

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Robin Eric Schmutz; Leonard Schneider; [2023]
    Nyckelord :Expected shortfall; Trading book; Historical simulation; Parametric estimation; Backtesting; Business and Economics;

    Sammanfattning : In light of the revised 2019 proposals constituting the Fundamental Review of the Trading Book, which amend the third Basel Accord, expected shortfall is set to replace value at risk as the risk measure dictating banks' capital reserving requirements for exposure to market risk. This paper examines how best to accurately estimate expected shortfall from a regulatory perspective by carrying out an array of non-parametric as well as parametric methods over the recent years of financial instability.

  5. 4. Modelling Risk in Real-Life Multi-Asset Portfolios

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Karin Hahn; Axel Backlund; [2023]
    Nyckelord :Risk modelling; multi-asset portfolios; risk factor models; time series analysis; regression; Riskmodellering; finansiella portföljer; riskfaktormodeller; tidsserieanalys; regression;

    Sammanfattning : We develop a risk factor model based on data from a large number of portfolios spanning multiple asset classes. The risk factors are selected based on economic theory through an analysis of the asset holdings, as well as statistical tests. LÄS MER

  7. 5. 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
