1. Modeling of Foreign Exchange Swap Distributions : A statistical evaluation of two stochastic models
Master-uppsats, Linköpings universitet/ProduktionsekonomiSammanfattning : 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
2. Copula approach to fitting bivariate time series
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : 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
3. DCC-GARCH Estimation
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : When modelling more that one asset, it is desirable to apply multivariate modeling to capture the co-movements of the underlying assets. The GARCH models has been proven to be successful when it comes to volatility forecast- ing. LÄS MER
4. A heteroscedastic volatility model with Fama and French risk factors for portfolio returns in Japan
Kandidat-uppsats, Stockholms universitet/Statistiska institutionenSammanfattning : This thesis has used the Fama and French five-factor model (FF5M) and proposed an alternative model. The proposed model is named the Fama and French five-factor heteroscedastic student's model (FF5HSM). The model utilises an ARMA model for the returns with the FF5M factors incorporated and a GARCH(1,1) model for the volatility. LÄS MER
5. Risk Modeling of Sustainable Mutual Funds Using GARCH Time Series
Master-uppsats, KTH/Matematisk statistikSammanfattning : The demand for sustainable investments has seen an increase in recent years. There is considerable literature covering backtesting of the performance and risk of socially responsible investments (SRI) compared to conventional investments. LÄS MER
