    Sammanfattning : The financial portfolio model often referred to as the Black-Litterman model is analyzed using two approaches; a mathematical and a behavioral finance approach. After a detailed description of its framework, the Black-Litterman model is derived mathematically using a sampling theoretical approach. LÄS MER

  3. 2. Pricing Portfolio Credit Derivatives

    Författare :Alexander Herbertsson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Portfolio credit risk; intensity-based models; dynamic dependence modelling; default contagion; CDS; synthetic CDO tranches; index CDS; k-th-to-default swaps; CDS-correlation; default-correlation; Markov jump processes; multivariate phase-type distributions; matrix-analytic methods;

    Sammanfattning : This thesis consists of four papers on dynamic dependence modelling in portfolio credit risk. The emphasis is on valuation of portfolio credit derivatives. The underlying model in all papers is the same, but is split in two different sub-models, one for inhomogeneous portfolios, and one for homogeneous ones. LÄS MER

  7. 5. Mean-Variance Portfolio Optimization : Eigendecomposition-Based Methods

    Författare :Fred Mayambala; Torbjörn Larsson; Elina Rönnberg; Juma Kasozi; Ann-Brith Strömberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Modern portfolio theory is about determining how to distribute capital among available securities such that, for a given level of risk, the expected return is maximized, or for a given level of return, the associated risk is minimized. In the pioneering work of Markowitz in 1952, variance was used as a measure of risk, which gave rise to the wellknown mean-variance portfolio optimization model. LÄS MER
