    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

    Författare :Viktor Ågren; [2023]
    Nyckelord :risk metric; expected shortfall; backtest; value at risk; empirical analysis;

    Sammanfattning : In this work, we look into the practical applicability of three joint quantile and expected shortfall regression backtests. The strict, auxiliary, and intercept ESR backtests are applied to the historical log returns of the OMX Stockholm 30 market-weight price index. LÄS MER

  4. 3. 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

  5. 4. A time series analysis of the impact of the COVID-19 pandemic on container shipping freight rates: An application to the Asia-Europe trade route

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Chen Yuchun; Zhou Shiyu; [2022-08-03]
    Nyckelord :Container shipping; Freight rates; COVID-19; Oil prices; Stock market prices; Time series model; GARCH;

    Sammanfattning : The outbreak of the COVID-19 pandemic caused a sudden disruption to the shipping industry. However, for container shipping, freight rates have reached record highs during the pandemic. Shipping companies realise that understanding the impact of exogenous shocks on freight rate fluctuations to forecast freight rates is critical. LÄS MER

  7. 5. Covid-19 och börsvärdets påverkan av volatiliteten

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