  1. 1. Volatility Forecasting - A comparative study of different forecasting models.

    Kandidat-uppsats,

    Författare :Emil Sturesson; Anton Wennström; [2023-06-29]
    Nyckelord :Volatility; GARCH; EGARCH; t-GAS; HAR-RV; Realized GARCH; Volatility Forecasting; Volatility Modelling;

    Sammanfattning : This study evaluates the out-of-sample forecasting performance of different volatility mod- els. When applied to XACT OMXS30, we use GARCH(1,1), EGARCH(1,1), and t- GAS(1,1) to forecast squared daily returns while Realized GARCH(1,1) and HAR-RV are used to forecast Realized Variance. LÄS MER

  3. 2. Value at Risk Estimation using GARCH Family Models: A Comparison of Different Specifications and Distributions.

    Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Författare :Khaled Jrideh; [2023-05-26]
    Nyckelord :;

    Sammanfattning : The objective of this study is to compare the performance of different GARCH models, under various conditional distribution assumptions, to predict one-day-ahead Value-at-Risk (VaR) for three stocks: Swedbank, Handelsbanken, and SEB over the Covid-19 period. The performance is evaluated using Kupiec, Christoffersen tests and the Quadratic Loss. LÄS MER

  4. 3. Modeling of Foreign Exchange Swap Distributions : A statistical evaluation of two stochastic models

    Master-uppsats, Linköpings universitet/Produktionsekonomi

    Författare :Ludvig Ehrenpreis; Eriksson Oscar; [2023]
    Nyckelord :term structure measurement; optimization; foreign exchange swaps; interest rates; FX; model comparison; FX swap models;

    Sammanfattning : The global foreign exchange (FX) market is one of the world's largest financial markets and a significant part of this market concerns the trading of FX swaps. For banks and other financial institutions, it is of great interest to model these swaps as accurately as possible, as this could improve their risk management. LÄS MER

  5. 4. 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

  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
