  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

  2. 2. Statistical Inference of Tangency Portfolio in Small and Large Dimension

    Författare :Stanislas Muhinyuza; Taras Bodnar; Dietrich von Rosen; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Tangency portfolio; Mean-variance portfolio; High-dimensional asymptotics; Test theory; Mathematical Statistics; matematisk statistik;

    Sammanfattning : This thesis considers statistical test theory in portfolio theory. It analyses the asymptotic behavior of the considered tests in the high-dimensional setting, meaning k/n → c ∈ (0, ∞) as n → ∞, where k and n are portfolio size and sample size, respectively. LÄS MER

    Sammanfattning : The purpose of this thesis is to analyze real estate investments from the vantage point of an institutional multi asset investor perspective, both in terms of the potential benefits real estate can bring as well as the challenges it can pose. The thesis consists of six papers and approaches the research question from three distinct perspectives. LÄS MER
