  1. 1. Mean-Variance Portfolio Optimization : Eigendecomposition-Based Methods

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

    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
