  1. 1. Impact of Quantitative and Qualitative Parameters on Stock Performance

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Fredrik Nivre; Martin Sjöbohm; [2022]
    Nyckelord :Applied mathematics; regression analysis; financial markets; qualitative parameters; quantitative parameters; Tillämpad matematik; regressionsanalys; finansiella marknader; kvalitativa parametrar; kvantitativa parametrar;

    Sammanfattning : Stocks belonging to publicly traded companies is a topic which in society is mystified and by some considered to be an unpredictable phenomenon where you either make an economic loss or gain seemingly by chance. Despite this, there are numerous fields of work where the sole purpose is to predict the movement of stocks in order to maximize economic gain. LÄS MER

  3. 2. Online intra-day portfolio optimization using regime based models

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Matematisk statistik

    Författare :Sara Hafström Fremlin; [2019]
    Nyckelord :Multi-period portfolio selection; Model predictive control; Hidden Markov model; Mathematics and Statistics;

    Sammanfattning : In this thesis model predictive control (MPC) is used to dynamically optimize a portfolio where the data is sampled every 5 minutes. Previous research has shown how MPC optimization applied to daily sampled financial data can generate a portfolio that exceeds the value of standard portfolio strategies such as Strategic asset allocation.

  4. 3. Beating the MSCI USA Index by Using Other Weighting Techniques

    Master-uppsats, KTH/Matematisk statistik

    Författare :Trotte Boman; Samuel Jangenstål; [2017]
    Nyckelord :;

    Sammanfattning : In this thesis various portfolio weighting strategies are tested. Their performance is determined by their average annual return, Sharpe ratio, tracking error, information ratio and annual standard deviation. LÄS MER

  5. 4. Price Impact Correlation Between Buy-/Sell-Pressure in the Stock Market and Subsequent Price Changes

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Eric Saidac; Fredrik Lidefelt; [2017]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : In this thesis, the correlation between aggregated buy-/sell-pressure and price change is analyzed, something often referred to as price impact. The purpose is not only to find a model that can explain how prices change given a certain traded volume, but also to see how much of the variance in price changes results from the actual buy- or sell-pressure.

  7. 5. Robust portfolio optimization with Expected Shortfall

    Master-uppsats, KTH/Matematisk statistik

    Författare :Daniel Isaksson; [2016]
    Nyckelord :Robust Portfolio Optimization; Risk Management; Expected Shortfall; Elliptical Distributions; GARCH model; Normal Copula; Hybrid Generalized Pareto-Empirical-Generalized Pareto Marginals; Markowitz Mean-Variance Optimization; Contribution Expected Shortfall;

    Sammanfattning : This thesis project studies robust portfolio optimization with Expected Short-fall applied to a reference portfolio consisting of Swedish linear assets with stocks and a bond index. Specifically, the classical robust optimization definition, focusing on uncertainties in parameters, is extended to also include uncertainties in log-return distribution. LÄS MER
