    Abstract : 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. READ MORE

  4. 3. The impact of macro-economic indicators on credit spreads

    University essay from KTH/Matematisk statistik

    Author : Marouane Brahimi; [2017]
    Keywords : ;

    Abstract : A model of credit spreads variations, based on macroeconomic and market variables, has been developed and presented in this paper. Credit spreads of speculative and investment grade bonds have been investigated, leading us to a linear relationship between their quarterly variations. READ MORE

  5. 4. Risk contribution and its application in asset and risk management for life insurance

    University essay from KTH/Matematisk statistik

    Author : Jesper Sundin; [2016]
    Keywords : Risk contribution; capital allocation; Value-at-Risk; elliptical distri-bution; multivariate log-normal distribution; kernel estimation;

    Abstract : In risk management one important aspect is the allocation of total portfolio risk into its components. This can be done by measuring each components' risk contribution relative to the total risk, taking into account the covariance between components. READ MORE
