  1. 1. Portfolio Optimization Problems with Cardinality Constraints

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Abolgasem Esmaeily; Felix Loge; [2023]
    Nyckelord :Portfolio Optimization; Modern Portfolio Theory MPT • Mixed Integer Programming MIP ; Efficient Frontier; Cardinality Constraints; Daily Returns; Expected Returns; Asset Allocation; Diversification;

    Sammanfattning : This thesis analyzes the mean variance optimization problem with respect to cardinalityconstraints. The aim of this thesis is to figure out how much of an impact transactionchanges has on the profit and risk of a portfolio. We solve the problem by implementingmixed integer programming (MIP) and solving the problem by using the Gurobi solver. LÄS MER

  3. 2. Portfolio Optimization Problems with Transaction Costs

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Stina Gustavsson; Linnéa Gyllberg; [2023]
    Nyckelord :Portfolio optimization; variable transaction costs; fixed transaction costs;

    Sammanfattning : Portfolio theory is a cornerstone of modern finance, and it is based on the idea that an investor can reduce risk by diversifying their investments across various assets. In practice, Harry Markowitz mean-variance optimization theory is expanded upon by taking into account variable and fixed transaction cost, making the model slightly more reliable. LÄS MER

  4. 3. Dynamic Covariance Modelling Using Generalised Wishart Processes

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Fredrik Nilsson; [2023]
    Nyckelord :Covariance matrix; generalised Wishart process; Bayesian inference; Markov chain Monte Carlo; Hamiltonian Monte Carlo; Mathematics and Statistics;

    Sammanfattning : Modern portfolio theory was pioneered by Markowitz who formulated the mean-variance problem, without which any discussion on quantitative approaches to portfolio selection would be incomplete. The framework boils down to finding the expected return $\mu$ and covariance $\Sigma$, after which the solution is proportional to $\Sigma^{-1}\mu$. LÄS MER

  5. 4. How to Get Rich by Fund of Funds Investment - An Optimization Method for Decision Making

    Master-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Författare :Sabina Colakovic; [2022]
    Nyckelord :Modern Portfolio Theory; Markowitz Model; Mean-Variance Optimization; Valueat-Risk; Conditional Value-at-Risk; Geometric Mean Return; Efficient Frontier; Portfolio Optimization; Markowitz 2.0;

    Sammanfattning : Optimal portfolios have historically been computed using standard deviation as a risk measure.However, extreme market events have become the rule rather than the exception. To capturetail risk, investors have started to look for alternative risk measures such as Value-at-Risk andConditional Value-at-Risk. LÄS MER

  7. 5. Black – Litterman eller Markowitz : En jämförelse av optimerade portföljer och OMXS30 index

    Kandidat-uppsats, KTH/Fastigheter och byggande

    Författare :Andreas Andrijasevic; Emma Viberg; [2022]

    Sammanfattning : Varje investerare vill se sitt kapital växa så mycket som möjligt men samtidigt inte utsätta kapitalet för onödiga risker. Högre risk, högre avkastning är två synonymer inom den finansiella världen. Investerare världen över söker hela tiden nya möjligheter att öka sin avkastning utan att behöva höja sin risk. LÄS MER
