1. Simulation-Based Portfolio Optimization with Coherent Distortion Risk Measures
Master-uppsats, KTH/Matematisk statistikSammanfattning : 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
2. 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 statistikSammanfattning : 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
3. Robust portfolio optimization with Expected Shortfall
Master-uppsats, KTH/Matematisk statistikSammanfattning : This thesis project studies robust portfolio optimization with Expected Short-fall applied to a reference portfolio consisting of Swedish linear assets with stocks and a bond index. Specifically, the classical robust optimization definition, focusing on uncertainties in parameters, is extended to also include uncertainties in log-return distribution. LÄS MER
4. Prediction of Volatility and Value at Risk with Copulas for Portfolios of Commodities
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Value at Risk (VaR) is a popular measurement for valuing the risk exposure. Correct estimates of VaR are essential in order to properly be able to monitor the risk. This thesis examines a copula approach for estimating VaR for portfolios of commodities. The predictions are made from a semi- parametric model with Monte Carlo methods. LÄS MER
